Summary: intermittent xfs crash
Product: File System
Version: 2.5
Kernel Version: 2.6.32-rc8
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: XFS
AssignedTo: xfs-masters@xxxxxxxxxxx
ReportedBy: kevmitch@xxxxxxxxx
Regression: Yes
After upgrading from 2.6.32-rc7 to rc8 I have experienced a number of
unexpected crashes that appear to be related to my xfs filesystems. When these
occur, dmesg says:
[33091.758929] xfs_force_shutdown(sda6,0x2) called from line 1043 of file
fs/xfs/xfs_log.c. Return address = 0xffffffff8114c5d3
[33091.758951] Filesystem "sda6": Log I/O Error Detected. Shutting down
filesystem: sda6
[33091.758956] Please umount the filesystem, and rectify the problem(s)
...
[33171.850058] Filesystem "sda6": xfs_log_force: error 5 returned.
[33191.540124] No probe response from AP 00:16:b6:26:41:29 after 500ms,
disconnecting.
Any further attempts to access files on the affected filesystem hang, however
anything else that has already been loaded into memory continues to work fine.
An ls -l shows the mountpoint as red with question marks in the metadata
fields. Attempts to unmount the filesystem fail saying that it is in use, while
an fuser on the mount point hangs like everything else.
This appears to occur approximately once daily with the typical usage patterns
for my laptop. There does not appear to be a particular action on my part that
triggers it. So unfortunately it will be difficult to consistently reproduce.
It can occur quite suddenly under only mild disk usage such as saving,
compiling a latex document followed by rereading the postscript file. I recall
that it also occurred once after a suspend to ram.
Let me know if there is any additional information I can provide.
