Questions about XFS

[Steve Bergman]

Hi Ben,

I'm setting up a new server right now, and I'm breaking it up into a
number of different LV's for flexibility. I've gone through a number
of possibilities, and I think it's going to look something like this:

/ - Ext4
/root - Ext4
/home - Ext4
/var - Ext4
/usr/local - Ext4
/usr/local/worktmp - XFS (Very intensive & time-consuming random
writes, here. But all files are temporary work files. XFS is
performing well here in my testing.)
/usr/local/data - Ext3 (Cobol doesn't know about fsync. I need
pony-magic in this LV.)

Backup on the /usr/local/worktmp is not critical, due to its nature.
But can't I just lvm2-snapshot an XFS LV and rsync that to USB drive
like I do everything else?
