ReadyNAS NV (Sparc) OS Partition Full

Hi I've been doing a lot of googling and think I'm nearly at the point I can get access back to my NV Frontview. Basically, NFS started to fail, then CIFS went down, then I got all sorts of o...

That's what I thought, but unfortunately I don't have a scooby when it comes to LVM2 commands such as vgscan and vgchange.

I'm pretty sure my data volume is fine.

Any chance you could let me know the commands I would need to mount it?

Thanks again.

Ok, a bit more googling gets me:

start_raid.sh
mount /dev/hdc1 /sysroot
chroot /sysroot
mount proc
vgscan
vgchange -ay c
mount -a

Obviously I've done the first two lines to get me where I am now, but is the rest of that sequence of commands correct? I'd rather copy the syslog if I can.

ok I jumped in a did it anyway, all looks good, copied all 1.7 GB with:
cp /var/log/syslog /c/backup/

then did:
echo "" > /var/log/syslog

So last question, how to I cleanly unmount everything before rebooting (and do I need to initiate the reboot from the telnet prompt)?

Thanks.

To reboot once you've unmounted everything and run

# vgchange -a n

to deactivate the LVM group you then just need do

# reboot -f

  So what does the
  # touch /.os_update
  # sync
  do?
  
  Is this just to force a resync? Do I need to do this if so, because it will take days if previous experience is anything to go by?

    Never mind, figured it out (basically just umount everything previously mounted right?)
    
    So after the reboot, I'm still getting this:
    
    Is this to be expected? Is this because when I did the OS re-install the OS partition was already too full to complete the re-install and now I just need to do it again?
