Hi Lists, (XFS list CC'ed)
We are encountering what looks like a race on both ext3 and XFS on a high-load mailserver.
Here is the cituation: We have a high-load mailserver serving IMAP from Maildirs. We originally had the maildirs on ext3 but the kernel eventually Oopsed every ~20 hours (Oops - included) - we then moved the Maildirs to XFS thinking the problems where history, but now we get a somewhat similar error from XFS (inluded). They both look like a race to me but I am not able to get more out of it.
System: IBM Dual Xeon P4 - IBM ips raidcontroller (raid 0+1) ~150G. Kernel: Linux 2.6.9 SMP
So buttomline both ext3 and XFS causes crashes. Comments anyone? ...We are desperate.
Here is what XFS says: <SNIP> Filesystem "sdb1": xfs_trans_delete_ail: attempting to delete a log item that is not in the AIL xfs_force_shutdown(sdb1,0x8) called from line 382 of file fs/xfs/xfs_trans_ail.c.
