/usr accidently destroyed.

[Nigel Green]

When extending the /usr filesystem, I accidently ran the newfs command rather than extendfs, as a result /usr is now empty.

is there any way of recovering this FS from the recovery CD or is this a straightforward re-install.

Hi,

Do you have a similar machine ? You can copy /usr from it.
Additionally, if you have a make_recovery backup, you can use it as follows:
mt -f /dev/rmt/0mn fsf 1
cd /
tar xv ./usr (or tar xv /usr You have previously check the output tar tv ) I don't remember exactly how the files are backed up.
If you don't have any of these options, so install mini system and restore the computer from full backup.

Well there are a couple of options for you.

If you have a recent backup, say tar or fbackup, you can use the statically linked binaries in /sbin/ to restore it.

If you have a make_tape_recovery tape you might be able to restore from it, but there is no 'mt' command in /sbin, which you need to skip over the boot header.

You could also boot from a make_tape_recovery tape and restore your OS from it.

Good luck.

Restore /usr from last good backup.

There are a couple of things I neglected to mention in the original post. This a new server which we haven't yet backed up as we don't have a tape drive attached.

We can't just copy /usr from another machine because we can't get the network services started as it won't boot past single user mode.

thanks

Hi,

If you don't have a backup from this server, ignite or some other backup, then there is no choice, but reinstall.

Hope this helps.

Nigel,

If you're that early on in the install process, it would be faster to just begin again than it would to experiment with prospective solutions.

[Patrick Wallek]

Yep, I'd agree with Sanjay here. Reinstall is probably your best option.

[Hilary Nicholson]

Looks like a re-install situation.

Can't think of any other way round this.

Once you re-install it would be an idea to backup across the network, or use make_net_recovery to get an ignite abckup

Thanks for the input guys....and Hilary..i thought that may be the case, but you never know. I'll dig out the install CD's!
