Hi,
I'd like to know what would be the best way to remove an iscsi lvm storage from a server. (removing all reference to that storage etc.)
The storage in question will be reset and reformated and used on a different server; so no LVM export is needed.
Do I have to do lvremove ..., vgremove ..., pvremove ... and do an
iscsiadm -m node -T ... -p ... -u and
iscsiadm -m node -o delete -T ... -p ...
in order to achieve that?
Or is there some more simple way?
Thanks for any suggestion and best regards . Götz

This may be a stupid question, but couldn't you simply umount the storage from everywhere, maybe the iscsiadm commands, and then just unplug the thing? Why do you need to do *anything* with lvm?

AFAIK LVM etc create some traces and file information in some places/caches .. and I like to remove all traces...

My approach would be:
* Disable all volume groups on the iSCSI LUN(s) with "vgchange -a n ..."
* Use iscsiadm to log out of the target and delete it from the database
* Run vgscan to update the LVM cache

umount any file systems, remove them from /etc/fstab, then vgremove the volume group should be sufficient to remove history of the LV's and VG's ... I don't believe its neccessary to pvremove the individual disks.
then drop the target LUN on the storage server.
