[Xen-devel] LVM snapshotting on dom0 panics XFS root on pv domU
List,
When testing a script i''m using on a few linux domU''s, one
kept crashing.
Turns out this is related to XFS (root domu filesystem?) somehow,
here''s the
only useful output I managed to get out of a testing vm trying to reproduce
the problem:
DomU console:
slackware login: [9236870.652650] I/O error in filesystem ("sda1")
meta-data
dev sda1 block 0x101149 ("xlog_iodone") error 5 buf count 10240
[9236870.652699] Filesystem "sda1": Log I/O Error Detected. Shutting
down
filesystem: sda1
[9236870.652704] Please umount the filesystem, and rectify the problem(s)
This happens immediately after taking a snapshot of the volume i''m
using as
backend for sda1.
( disk = [ ''phy:/dev/SAS/xfsbug,sda1,w'' ] )
Thoughts? Is this a known bug? (I have yet to test this on anything but xen
3.3)
Kind regards,
-Bart Van Kerckhove
