Hi i have tested a xfs+LVM installation with the scalix (HP OpenMail) Mailserver (it's a little time ago). I had at that time some problems using xfs_freeze. I used a script for freezing the fs and making storing the snapshots. Sometimes the complete Server hangs (no blinking cursor, no possible logins, no network). I don't know if it was a hardware problem or if it was the xfs-software. I installed/compiled the newest kernel for this system (i think it was a 2.6.9) to check out if it's maybe a kernel-problem. But on the next days, the system hangs again. After that i used reiserfs again.
I tested it with Suse Linux Enterprise Server 8. Has someone heared about such problems? That is the only reason that i have a bit fear to use xfs for a critical database :/.
