problems with / file system

Toscanini Montaño — Mon, 24 Jul 2006 13:03:23 GMT

Hi all,

I have a rp7400 with HP-UX 11.11 when I did a bdf command a can see that the / file system is mount in /dev/root.

In the /etc/fstab file is the following line:
/dev/vg00/lvol3 / vxfs delaylog 0 1

Are any people for help me?

Thanks.

The following should fix this for you:

# mv /etc/mnttab /etc/mnttab.bad
# mountall

Usually this happens when a system is brought up to multi-user mode from LVM maintenance mode. Rather than doing an "init 3", it should have been re-booted.

This /dev/root setup tells me that you are running in LVM maintenance mode. Did you boot to lvm maintenance mode to do something like root filesystem size extension or anything like than and left it in that position recently ?

If you have a chance, reboot it and let it come up without any interruptions on the boot time (10 second delay point that is, just do not touch anything and let it go). If the setup does not change, your autoboot sequence might have been changed and you may need to reset it.

Thanks all,

I rebooted the server and I went to the single user mode, so I moved the /etc/mnttab to mnttab.prev and mount all again. The problem was there.

I checked the /dev/vg00 and the volumen Lvol3 is not there.

brw-r----- 1 root sys 64 0x000008 May 15 2002 lvol8

Can I recreate the lvol3 in the vg00 wihtout loss of data?

Why did you go to the single user mode ? Did the server fail to reboot otherwise ? If not, let the system boot to its default init level without interrupting the boot process at all. If you have problems doing that, report those and you will get more help I am sure.
