Hi, Thanks for your reply. The file system type is xfs. And I found xfsdump/xfsrestore can undo the remove. I use dd to copy the partition as one image file. How do I mount the image as read-only device? Then I can try to recover the deleted files/directory anytime. Thanks!

I'm having some difficulty finding a method to shrink my /home to expand my /.? They both correspond to LVMs.? It is my understanding that one cannot shrink a xfs filesystem.? One must back it up (xfsdump), remove (lvremove) redefine it and then restore it back (xfsrestore). Okay, I'm running into a problem where /home? needs to be "unused".? If tried going in to "maintance mode", but I ran into a problem with the mount command (after issuing a 'chroot /sysroot').? I then tried using SystemRescueCD to boot to, but it wouldn't...

I just copied a file system using xfsdump|xfsrestore At least 1 new directory had been created on the source during the xfer (took 9+hours -- 7TB), so I wanted to verify I hadn't missed anything. Using rsync: > rsync --version rsync version 3.1.0 protocol version 31 Capabilities: 64-bit files, 64-bit inums, 64-bit timestamps, 64-bit...

...does not support ACLs. You must have the SGI supplied XFS enable RH kernel though. I'm not 100% positive, but I'm pretty sure that does support ACLs. (XFS has = had ACL support under IRIX for sometime, so it came in the package when it was = ported to Linux.) Unfortunately, xfsdump and xfsrestore had a bug until March of this year and = they don't save/restore ACLs. Normal Linux backup/restore programs definitely = don't support ACLs. =20 If you are going to backup/restore via another server on the network, it is not = a problem. If you are going to use Linux Tools to do backup/...
