Weird disk problems

Jason_309 — Thu, 24 Apr 2008 15:44:39 GMT

I have a disk that went down. While it was up i had oracle apps running. There are allot of proccesses that are still running and can not be killed do to the disk going down. I think i need to reboot to get rid of but not sure. Also i am getting the follwoing errors in syslog:

Apr 24 07:54:47 svr033 vmunix: msgcnt 121 vxfs: mesg 008: vx_direrr: vx_dirscan_2 - /u11 file system inode 7 block 775 error 5
Apr 24 07:54:47 svr033 vmunix: msgcnt 122 vxfs: mesg 025: vx_wsuper - /dev/vg02/lvol5 file system super-block update failed
Apr 24 07:55:00 svr033 vmunix: msgcnt 123 vxfs: mesg 016: vx_ilisterr - /u11 file system error reading inode 3
Apr 24 07:55:00 svr033 vmunix: msgcnt 124 vxfs: mesg 025: vx_wsuper - /dev/vg02/lvol5 file system super-block update failed

Can anyone tell me if replaceing the disk and booting will clear this up?

Thank you.

Hi Jason:

I would expect to see hung processes. They are waiting on an I/O that isn't going to happen and until it does, even a 'kill -9' isn't going to terminate them. A reboot will certainly vanquish them!

You need to replace your failed disk. Follow the guidelines herein:

Shalom,

There were open file handles when the disk died. It is not weird that processes will hang.

fuser -cuk /filesystem if there is still a filesystem mounted.

Reboot will clear this, but startup jobs may hang depending on what disk this is.

could not find file system mounted.

So i will replace the disk. Then reboot. Does this sound correct?

Hi (again) Jason:

I suggest that you take a few minutes, first, to read through the document I cited, *before* acting.
