Server Not booting, file system I/O error

Hello,

Our HP-UX server went down and its given error.

INIT: Command is respawning too rapidly.
Will try again in 5 minutes.
Check for possible errors.

When I further investigated the logs I found that some file systems are given I/O error.

vxfs fsck: V-3-20005: /dev/vg00/lvol8:read of super-block on /dev/vg00/lvol8 failed: I/O error
/dev/vg00/lvol8:file system check failure, aborting ...

When tried to run fsck manually in single user mode fsck is not working.

Please let us knw the issue

use fsck -F vxfs -o full /dev/vg00/rlvol8

Notice the "r" in front of lvol8

No difference its still the same:

# fsck -F vxfs -o full /dev/vg00/rlvol8
vxfs fsck: V-3-20005: read of super-block on /dev/vg00/rlvol8 failed: I/O error
file system check failure, aborting ...

Re: Server Not booting, file system I/O error

there is an IO failure on the filesystem, boot the system in single user mode, fsck and mount all other filesystems, recreate that filesystem and from a valid backup restore data on to that.

Re: Server Not booting, file system I/O error

yeah i know that however I have couple of other file systems which too are given the same error messages, those were mounted as /var,/usr,/tmp & /usr , this means there can be issue with the hardisk and I will have to change the faulty disk with a new one and then again re-install the OS ?

You should have an ignite backup. If not, you will have to go through setup again.

If this is a production server, you have a big problem.

Maybe you should look for specialized help from someone from HP in your country in order to minimize downtime.

Hi,

If you dont have ignite and fsck in sigle user mode also fails, you are in real loop :)

Try to remove any "respawn"entries from /etc/inittab and try a reboot also. Have a backup before you do that.
