Vclass server cannot boot up normally

[mohdamir]

So what u mean is, when the system cannot find lvol for / (root) at /etc/fstab, it will replace it with /dev/root, isn't it?

[Avinash20]

Yes,

we would have suggested to uncomment and mv mnttab and and do a mount -a, but since none of the services have been started, I would strongly recommened you to unhash the entry and then boot the server again .

By the way why is the entry in fstab commented ?

Was it commented after reboot.

If not, then uncomment and reboot the server.

Also please don't forget to assign points.

We also don't know. I'll follow your recommendation. However, how about other services which are failed duirng boot up? Are they also happened due to this problem?

[Avinash20]

If root filesystem doesn't get mounted "/sbin/sh" and /bin diretory which is needed to start all the script wont be found.
Hence all the above errors.

Hence uncommenting it will resolve the issue with the services not starting.

Okey, it makes sense. But how come it can up if I bring up accordingly? Single user mode > Init 2 > Init 3.

[Avinash20]

Since /dev/root got mounted as /, we are able to make the system up

I believe we could avoid the downtime via following

Make down your application is it is running

Edit /etc/fstab and uncomment the entry /dev/vg00/lvol3

The n

# mv /etc/mnttab /etc/mnttab.old
# mount -a
# bdf

If /dev/vg00/lvol3 gets mounted as / then

# init 1
# init 3

Okey.. I've done as your suggestion. Hopefully this server do not down again. Thanks a lot for your help (^_^)
