New size too large to be expressed in 32 bits? e2fsprogs

I am running Ubuntu 11.04 and running into an issue expanding an ext4 filesystem to larger than 16 TBs. When I try to resize the filesystem using resize2fs, it gives me the error:

"New size too large to be expressed in 32 bits".

I am now aware that older versions of e2fsprogs couldn't go larger than 16 TBs but was wondering if anyone has had any luck creating a filesystem larger than 16 TB on EXT4? I know that their may have been some recent developments that allow for larger filesystems on EXT4..

Any help would be greatly appreciated!

EXT4 is still limited to 16TB. Think about how much storage that actually is even just a year ago and the decision to keep the limit that low doesn't seem as short-sighted. Now it's possible (though VERY difficult to find) to hit that limit with only 4 drives. If you actually have to have a filesystem that's >16TB and still use the EXT4 format than creating an lvm with multiple logical volumes would be the solution in that case. I'd recommend using something designed a bit more towards large volumes like XFS or ZFS. The only limitation you may run into with XFS is that you can not shrink a volume, and ZFS is really meant to be run on Solaris tho I can attest that it works well with linux.

You must have missed these two links when you Googled for a solution.

Do these not answer your question?
