Summary: XFS_WANT_CORRUPTED_GOTO in xfs_bmap_read_extents
Product: Linux XFS
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: XFS kernel code
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: dean-oss.sgi.com@xxxxxxxxxx
i'm running 2.4.30 with linux-2.4.22-VFS-lock.patch (from EVMS sources)
and using lvm1 snapshots -- without doing xfs_freeze. the snapshots are
mounted -o ro.
last night i got this while a rdiff-backup was running on a snapshot:
XFS internal error XFS_WANT_CORRUPTED_GOTO at line 4340 of file xfs_bmap.c.

i can't tell if the above was the snapshot filesystem or not, is the
device node hidden in that debug output somewhere? none of my filesystems
went down at this point -- the backup continued for 3 more minutes without
error, and this error is about 7 minutes into the backup.
this hardware has been rock solid for over a year now, i just switched to
xfs last weekend. i have no reason to suspect hardware.
