Had a major power supply failure on a Linux server managing various VxVM file systems on
a DAS RAID.. The RAID itself wasn''t affected and after Linux had rebooted I was
able to run fsck and replay the intent log of each file system .
There is one file system though on which the 'vxdump' command now hangs at the
point of mapping directories.
Tried to find structural errors by using 'fsck -n' , but that also hangs; when checking directory linkages..
However I can still list the entire directory tree and 'vxstat' reports no IO errors
with the underlying volume..
But if a file system can't be backed up then it's of no use in our environment.
What do people think? Is this a failure mode anyone recognises?
