Topic: Amend Wiki documentation

[ReetP]

Whilst upgrading the disks in my 7.3 server, I discovered a bit of a problem which I resolved though a search in the forums (strange but true !)

Much time could have been saved had this been added to the Wiki page :http://wiki.contribs.org/UpgradeDisk

I don't have a Wiki login so could someone kindly amend this accordingly as I think it is extremely relevant ? It probably need a small amount of editing - I have added some bits in italics.

Many thanks to all the developers for all their hard work. You really are appreciated !

Upgrading disks in a 7.x version

When you try to mount the disks to do a pre-restore, the original disk will not mount.

To mount the disk, you have to rename the volume group on the old drive (so that when you mount it it doesn't conflict with your existing volume group) and then mount it. Here's the procedure:

Boot from SME Server 7.1 install CD
press F5
type "sme rescue" at the command prompt and hit enter
Note: don't start the network and skip mounting the filesystem.
Code:

#mdadm -AR /dev/md5 /dev/hdx2
#lvm vgscan
#lvm vgs -v
#lvm vgchange -a n
#lvm vgrename orig_vg_name new_vg_name
#exit


Now remove the CD and reboot
Code:

#mdadm -AR /dev/md5 /dev/hdx2
#vgscan
#vgchange -a y new_vg_name
#mkdir /mnt/tmp
#mount /dev/new_vg_name/root /mnt/tmp


You should now be able to view all your old data under /mnt/tmp and if required you can use CopyFromDisk to restore the data as follows:
Code:

1. perform signal-event pre-backup on the old disk (probably too late now
2. /sbin/e-smith/db configuration setprop backup Program CopyFromDisk status enabled
3. /sbin/e-smith/signal-event pre-restore
4. /sbin/e-smith/signal-event restore-tape /mnt/tmp
5. /sbin/e-smith/signal-event post-upgrade
6. /sbin/e-smith/signal-event reboot.


When finished simply reboot and you system will be back to normal.

Thanks, I added those steps

My pleasure. Wish I could have done it myself, but probably better that a 'pro' does it !

You can do it yourself, it's better that way too as it spreads the workload amongst all of us.
