health check on mounted file system

[Stuart Powell]

I want to be able to create a script that will check the health of a mounted Serviceguard file system. From the man pages on fsck the -m option will not perform a sanity check on a mounted file system.
Anybody else been down this road?

you probably know this already but
lvdisplay -v /dev/vgxx/lvolxx|pg
gives you some info
fsadm /dev/vgxx/rlvolxx
gives you some config info, largefiles and such

You could run fsck with the -n option, but the results would not be reliable, since fsck would not be able to get a consistent view of the file system. If no errors are detected (unlikely on a busy fs) then all should be fine. However, there could be lots of errors reported (likely) although the fs is completely OK.

Best regards...
