Dynamic Root Disk

FOBF — Fri, 01 Aug 2008 18:55:09 GMT

Hello,

I made a DRD and i think there was a mistake in the creation time, i want to release the disk from DRD but i can not make the task.
i used drd umount, vgremove, from SAM and it's imposible.

Any help

Thanks

what do you mean "release the disk from the DRD"?

If you wish to use it for something else, just see if the drdvg is in lvmtab, and if so export it, then use pvcreate -f on the disk to re-use it elsewhere

he burnard

yes, i want to re-used it, to break the clone between disks, I tried to run vgexport and pvcreate on the disk but it's still in /etc/lvmtab.

Hello,

If I understand your question correctly, you
want to "undo" the DRD setup and start again.

Here is how to do it (of couyrse, firstly
you make sure that "drd umount" is run):

# lvrmboot -s drd00
Volume Group configuration for /dev/drd00 has been saved in /etc/lvmconf/drd00.conf

# lvremove -f /dev/drd00/lvol2
Logical volume "/dev/drd00/lvol2" has been successfully removed.
Volume Group configuration for /dev/drd00 has been saved in /etc/lvmconf/drd00.conf

# lvrmboot -d lvol3 /dev/drd00
Volume Group configuration for /dev/drd00 has been saved in /etc/lvmconf/drd00.conf

# lvremove -f /dev/drd00/lvol3
Logical volume "/dev/drd00/lvol3" has been successfully removed.
Volume Group configuration for /dev/drd00 has been saved in /etc/lvmconf/drd00.conf

# lvrmboot -r drd00
Volume Group configuration for /dev/drd00 has been saved in /etc/lvmconf/drd00.conf

# lvremove -f /dev/drd00/lvol4
Logical volume "/dev/drd00/lvol4" has been successfully removed.
Volume Group configuration for /dev/drd00 has been saved in /etc/lvmconf/drd00.conf

(truncated for other logical volumes
the sake of brevity)...

# vgremove drd00
Volume group "drd00" has been successfully removed.

Cheers,
