"Unknown error 990" is a classic "wildcard" error message given by XFS. You may want to unmount and then run xfs_repair(8) and then coordinate with the XFS team on their mailing list for more information. For whatever it's worth, I have a production setup using Linux kernel 2.6.11.11, DRBD 0.7.10, and XFS, and am not having any problems at all. I am not using LVM2, though, because I was under the impression that DRBD+XFS+LVM was not a very stable combination (see the mailing list archives of both DRBD and XFS lists for details). You may want to try without LVM, too, and see if you fare better. --> Jijo -- Federico Sevilla III : jijo.free.net.ph : When we speak of free software GNU/Linux Specialist : GnuPG 0x93B746BE : we refer to freedom, not price.
