Linux Creating a Partition Size Larger Than 2TBby NIX Crafton November 6, 2007 66 comments LAST UPDATED September 19, 2011

in CentOS, Debian Linux, File system

Frankly speaking, you cannot create a Linux partition larger than 2 TB using the fdisk command. The fdisk won't create partitions largerthan2 TB. This is fine for desktop and laptop users, but on server you need a large partition. For example, you cannot create 3TB or 4TBpartition size (RAID based) using the fdisk command. It will not allow you to create a partition that is greater than 2TB. In this tutorial, youwilllearn more about creating Linux filesystems greater than 2 Terabytes to support enterprise grade operation under any Linuxdistribution.

To solve this problem use GNU parted command with GPT. It supports Intel EFI/GPT partition tables. PartitionTable (GPT) is a standard for the layout of the partition table on a physical hard disk. It is a part of the ExtensibleFirmware Interface (EFI) standard proposed by Intel as a replacement for the outdated PC BIOS, one of the fewremaining relics of the original IBM PC. EFI uses GPT where BIOS uses a Master Boot Record (MBR).

(Fig.01: Diagram illustrating the layout of the GUID Partition Table scheme. Each logical block (LBA) is 512 bytes in size. LBA addresses that are negative indicate position from the end

of the volume, with 1 being the last addressable block. Imaged Credit Wikipedia)

Linux GPT Kernel Support

EFI GUID Partition support works on both 32bit and 64bitplatforms. You must include GPT support in kernelin order to use GPT. If you don't includeGPT support in Linux kernelt, after rebooting the server, the file system will no longer be mountable or the GPT table will get corrupted. By default RedhatEnterprise Linux / CentOS comes with GPT kernel support. However, if you are using Debian or Ubuntu Linux, you need to recompile the kernel. SetCONFIG_EFI_PARTITION

to y to compile this feature.File Systems

To create a partition start GNU parted as follows:# parted /dev/sdb

Output:

GNU Parted 2.3

Using /dev/sdb

Welcome to GNU Parted! Type 'help' to view a list of commands.

(parted)

Creates a new GPT disklabel i.e. partition table:

(parted)mklabel gpt

Sample outputs:

Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue?

Yes/No? yes

(parted)

Next, set the default unit to TB, enter:

(parted) unit TB

To create a 3TB partition size, enter:

(parted)mkpart primary 0 0

OR

(parted)mkpart primary 0.00TB 3.00TB

To print the current partitions, enter:

(parted) print

Make sure you replace /dev/sdb1 with actual RAID or Disk name or Block Ethernet device such as /dev/etherd/e0.0. Do not forget to update /etc/fstab, ifnecessary. Also note that booting from a GPT volume requires support in your BIOS / firmware. This is not supported on non-EFI platforms. I suggest you bootserver from another disk such as IDE / SATA / SSD disk and store data on /data.

Typically with Linux and large disks, I prefer just to use LVM directly on the disk, no partitioning at all. I find this to be very stable and manageable.

Ryan, how do you tell grub to load the kernel from a lvm partition? IMHO, grub wont mount logical volumes and thus, cannot find your kernel.

All supported releases of Ubuntu (ie 6.06 LTS and higher) do have CONFIG_EFI_PARTITION=y compiled into the kernel.

Reply

10Randall January 8, 2009 at 3:07 pm

Since recent versions of Ubuntu and Debian have CONFIG_EFI_PARTITION compiled into their stock kernels, you should remove the part abouthaving to recompile the kernel so that readers dont needlessly recompile their kernels.

What tripped me up is mkpart gpt is actually a lone command followed by a sub-command.Dont type them both at once, wait for the next prompt before typing gpt.

With EXT3 on most systems the max block size is 4096 bytes, which will still limit you to ~8TB for your filesystem.

14what? December 20, 2009 at 8:45 am

i dont understand the premise.

since i cant buy a > 2tb drive, i dont see the problem.

fdisk /dev/sda(make a partition of type fd, that spans the entire 2tb drive)fdisk /dev/sdbditto sdcditto sdd

mdadm (assemble sda through sdd into a raid 5 of size 6 terabytes)

then mkfs /dev/md0

show me where with the biggest drives you can buy as of today, that youll have to run fdisk against something larger then 2tb????

Great Post!!!

Prior to this article, I was having trouble partitioning a 6TB Raid 5 Array (4 x 2TB disks).Im running CentOS (2.6.18-164.10.1.el5) and used the following commands from this article and comments. Thanks!

-parted /dev/sda

mklabel gpt

mkpart primary 0 -0

quit

mkfs.ext3 /dev/sda

-

* Note:I first tried using gparted but something with the data types in the graphical interface didnt like the size of the raid array and was displaying

negative values. Stupid gui.

Reply

18Chad Farmer July 18, 2011 at 9:29 pm

Just for people who get search hits on this pageI suggest the commands:

parted /dev/sdamklabel gptmkpart primary 0 -0printquitmkfs.ext3 /dev/sda1

SassyZ needs to understand that file systems are created within partitions while GPT are applied to disks. In other words, parted mklabel gpt

/dev/sda writes a partition table to the first few sectors of a disk drive. The mkpart command creates a partition entry in that GPT. The firstpartition is named /dev/sda1. So the mistake in the last command is specifying the wrong device special file name. The command should bemkfs.ext3 /dev/sda1to create a file system in the first partition. The command mkfs.ext3will create a file system starting at sector zero andoverwrite the GPT. (Note Ive never tried a size of -0, so use print to verify the partition that was created.)

Try a hardware RAID for a change. The RAID controller will report a single huge drive to your OS. I just skip partitioning the RAID device altogether.*shrug*. Just mkfs /dev/sdb.No fiddling with exotic partitions. Not the prettiest of solutions, but very reliable nontheless.

Would this have anything to do with it

Warning: Device /dev/sdb has a logical sector size of 4096. Not all parts ofGNU Parted support this at the moment, and the working code is HIGHLYEXPERIMENTAL.

If so, how can I get around this? Im using four 2TB drives in RAID5 volume size is 5.9TB it is ISCSI.

No. Not unless you try to read the drive with a different operating system or reinstall the operating system. Without the partition table, other OSes will

think the drive is unpartitioned (blank). As long as you keep using Linux or perhaps BSD, just tell the system that the drive is a big single partition ( mount/dev/sdb -t ext3 /mnt/bigdrive -o noatime) and it should work fine.

If you want to protect the drive from another OS (I dont know why youd dual boot with a massive RAID like that) or make it more portable then youshould follow the instructions in the article for creating a GPT instead.

The BIOS does NOT use the MBR. It simply loads the first sector of the disk into memory at 0x7c00, and runs whatever is there. IBM way back whendecided to use an MBR to partition drives. The bios knows nothing about the partitions or how the MBR is layed out, and can perform perfectly withoutan MBR. So much mis information for such a small article. You can use a GPT with a standard bios, its just that EFI is aware of the GPT, where astandard bios knows nothing of it, and just loads the first sector of the disk, and lets it do its thing. All they did was move some code from the hard driveinto the firmware, doesnt really make any difference where it resides, its all software that performs the same function

A common message as there is not partition table. This also displayed when you have software raid devices such as /dev/md0

fdisk -l /dev/md0

Disk /dev/md0: 58.0 GB, 58004537344 bytes

2 heads, 4 sectors/track, 14161264 cylinders

Units = cylinders of 8 * 512 = 4096 bytes

Disk /dev/md0 doesn't contain a valid partition table

Nothing to worry. Just ignore warning.

I used parted as described to work with large arrays, so I am quite happy with it. One question though. What would be the easiest way to copy partitiontables between disks (not partitions!). I know in fdisk there was a tool called sfdisk that let you dump / rewrite partition tables from one disk to another.is there a similar procedure in parted? any hints greatly appreciated! Adrian

Reply

30Chad Farmer July 18, 2011 at 9:53 pm

GPT stands for GUID Partition Table. This mean that each partition is assigned a unique ID when the partition is created. So, copying the partitiontable is a BAD IDEA, even if you know to also copy the backup partition table at the end of the disk. You should run parted (or whatever) on eachdisk that needs the same partition table and create a new partition table with the same partition types and sizes, but with new (unique) GUIDvalues.

Although not well documented, parted will accept starting location and size in sectors, if values in MB are being rounded and causing slightlydifferent values than desired. To repartition the fourth disk sdd (and lose all of its content):parted -s /dev/sdd mkpart fat16 34s 1048609s

Note that Im worried about duplicating the GUID that uniquely identifies each partition, not the standardized GUID value that identifies thepartition type.

31Jord Wegge February 26, 2011 at 4:16 pm

Great Tut as always.

One question though All this assumes youve got a running system to which you plan to add a second >2TB device. When using GPT, most modernlinux distros will do as you described.

However, how do you install to such a device?

Situation = 8x2TB raid6 (hardware), and boot-able debian 6.0 cd -> The installer recognizes a 500 GB disk (I previously GPTed the device &partitioned it to my liking with gparted livecd).

Suggestions?

TIA,Jord.

32Jord Wegge March 11, 2011 at 7:36 pm

Solution for my original problem: ubuntu install cd (in my case 10.10) will only create GPT when the drive is large enough to require it, otherwiseit will stick to msdos mbr.So: make youre raid as you wish it to be and install straight from cd.

One smaller problem Im facing now is also GPT-related:I installed ubuntu on 3x2TB hw raid whilst there still was a 5X2TB soft raid in the same machine. Next I moved the data from the soft raid to thehw raid and expanded the hw raid to its full 8x2TB in raid 6.When now I want to enlarge /dev/sda3 (ext4) to full raid size I get blocked of by the GPT backup table

But I dont quite see how to do that.

quote missing in previous reply:

The backup GPT table is not at the end of the disk, as it should be. This might mean that another operating system believes the disk issmaller. Fix, by moving the backup to the end (and removing the old backup)?

Even when starting parted with: parted -a optimal, I was still seeing:Warning: The resulting partition is not properly aligned for best performance.on a large (3TB) Advanced Format 4k sector drive.

I found the solution is just to start at 1, not 0:

(parted) mkpart primary 1 -1

Will start the partition at the correct sector boundary, and the warning no loner appears. More info.

When you get ready to format your new huge partition, I recommend using -m0 with the mkfs command. This will give you the maximum amount of

space to use.The -m sets the reserved block to zero (0).

If you do not add that to the command, you will loose (i think) either 5 or 10% of the drive to reserved blocks.

Im getting the same errors from Parted as mentioned by Chris aboveWarning: Device /dev/sdd has a logical sector size of 4096. and Error: Invalid argument during write on /dev/sdd Retry/Ignore/Cancel? At whichpoint only Cancel does anything.

In my case the drive is a Hitachi XL3000 3TB (external USB 2.0) and I wanted to format it ext3. Since Parted didnt work for me, I partitioned it underOS X (Disk Utility) as a single 3TB partition. And then mkfs.ext3 and tune2fs -L for the label. Seems to be working now, but if someone smarter thanme wanted to explain how to do it without resorting to OS X, that would be awesome.

Any help?

Sean,

I seem to have just purchased the same drive you are talking about, and yes I had the same problem. I ended it up there by making an error in followingthe instructions above. If you look at the drive, you will notice two partitions on it. Both zero in size. Use rm command for each partition and go carefullyback to the beginning.Note, though, that the above instructions result with some empty space at the beginning of the drive. If you select units as Bytes, the empty space will bemoved to the end of the drive.

Hi Nick,

Thanks for the reply. While in Parted, I still cant get anywhere because the disks label remains unrecognized, and the mklabel command simply returnsthe above-mentioned error (pretty much every command in Parted returns the same error: unrecognised disk label). Should I be using a different Linuxtool to look at the drive?

>Gadgetman October 16, 2008>I could create on 3TB volume following guide above. But when rebooting, the pratition tabled is wrong. Pleas Help /T

Ive just found the cause of this problem.http://www.linuxquestions.org/questions/showthread.php?p=4519659#post4519659Maybe reply #9 explains the reason.Could anyone tell me whether this issue has already resolved or not.

Now the other question, how long will it take to fsck one of these 3TB filesystem? This could take many hours. Weve seen it take over 12 hours for a

large filesystem.

By default the OS will automatically fsck the filesystem every 25 mounts or 180 days, whichever comes first. This could be a serious issue if you wantto reboot the system 180 days from now, as your 4 minute reboot could turn into a 4+ hour wait for fsck to complete.

If you want to disable the automatic fsck upon boot, try this command:

# tune2fs -c 0 /dev/sdb1

tune2fs 1.41.12 (17-May-2010)

Setting maximal mount count to -1

`tune2fs -i 0 /dev/sdb1` will also disable the automatic fsck.

I am a little confused. Do I need to perform these steps prior to OS install, during the install or after the install?

Reply

52nixCraftApril 25, 2012 at 4:30 pm

Most modern installer will do these steps for you during installation only. If you add a new raid or large disk storage after the install, then you needto boot into os and type the commands.

Hi Master,i have problem when i create new partition:

Use the mkfs.ext3

#mkfs.ext3 /dev/mapper/mpath0/dev/mapper/mpath0 is apparently in use by the system; will not make a filesystem here!

Ive been working on this issue for almost day and I cant figure out how to format these partition.

Hi,

If I got a 20TB device /dev/sdb & I creat a 16TB parition /dev/sdb1

How do I create a second partition with the remaining space using parted?

Reply

57nixCraftJune 1, 2012 at 10:45 am

@Pete,

You can use the same command to create a partition:

mkpart primary 0.00TB 16.00TB

mkpart primary 16.00TB 20.00TB

print

You can do it interactively too. Just type mkpatand it will ask you various questions as follows:

(parted)mkpart

Partition type? primary/extended? primaryFile system type? [ext2]? ext4

Start? 16TB

End? 20TB

(parted) print free

Yeah, I should prbboaly wipe it clean and start over I just dont feel like reinstalling everything. There was a time when reinstalling windows felt excitinga new beginning, and all that shit. Now it just feels like work.I think Im gonna get one of those external USB drives. I saw dell selling 270 GB LaCie for$100 yesterday which seemed like a decent deal. Then I can back up both drives nightly (80G + 160G). a0|a0
