Summary: Error when remounting read-only
Product: Linux XFS
Version: Current
Platform: PC
OS/Version: Linux
Status: NEW
Severity: blocker
Priority: P1
Component: XFS kernel code
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: claes@xxxxxx
To repeat it I can just do "mount -o remount,ro /mnt". This problem prevents me
to do clean reboot. It hangs when rc-scripts are unmounting local filesystems
(root filesystem I assume). Problem does not occur when using Debian's stock
kernel. xfs_check does not report any error.
