Summary: recovery panic
Product: Linux XFS
Version: Current
Platform: All
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: XFS kernel code
AssignedTo: xfs-master@xxxxxxxxxxx

I was running ranholes -l 6710884 -v -a foo
The system locked up and I had to reset it.
When it came back up it looks like it was unable to
run recovery.
