Disabled Filesystem

Regina Mitchell — Fri, 02 Jun 2006 15:25:50 GMT

I am getting the following errors and my syslog file and /u05 is disabled. Any ideas, could this be a kernel parameter that may need to be adjusted?
I have a n4000 server running 11.0.

Unmount the filesystem and run a full fsck.

This has happened approx 2 weeks ago and we did what you suggested here. It has happended again. I'm trying to determine the root cause. The DBA wants me to TC the server to get a crash dump for HP to analyze? Do you think a crash dump will capture the root cause?

I don't think an analysis is going to help
but this message is very suspicious:

extent allocation unit summary number 452 marked bad

This strongly suggest that you are seeing i/o problems. Is syslog reporting any disk errors?

It never hurts to make sure that you are up to date on the latest vxfs and SCSI patches but if this is recurring after a -o full,nolog fsck then disk problems (or poor termination) are certainly something to be considered.

The only thing that really comes to mind is to make a script that uses adb to probe the kernel for some of the vx_ variables but I am really leaning towards a hardware problem.
