Re: 2 Terabyte File System Size Limitation - More like 16TB??

["William L. Jones" <jones@xxxxxxxxxxxxxxxxxx>]

I should have looked closer at mkfs.xfs.  You have only control over 
agcount or agsize
not both.

Fortunately  their is one other nob that can be turned with mkfs.xfs the 
size of
an inode.   So, if an inode size of 256 gets you to 2TB then setting the 
inode size
to 512 should get you to 4TB.  Since you can set the indoe to a maxium 2048 
you should
be able to create a 16TB file system on linux using xfs and LVM. Assuming that
LVM will allow you to address a 16TB logical volume.
