[CentOS] Best Practice to remove an ISCSI LVM from a system
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 .
