Hi, we have a two node cluster, our resources are several virtual machines running on kvm. The vm's reside in plain logical volumes, without a filesystem inside the lv's. The lv's reside on a SAN. I know that i can do a snapshot of a lv while having clvm when i acitivate it exclusively on one node. OK. I tried it via lvchange -aly. I got "lvchange Using logical volume(s) on command line. lvchange Activating logical volume "lv_cluster_01" locally". Seems to work. Then i'm able to take the snapshot. But what is when i'd like to activate the lv cluster-wide again ? Is the snapshot gone or corrupted ? I tried to activate it cluster-wide again with "lvchange -vay". Seems to work too. Because, if i leave it exclusively activated on one note, i loose my high availibilty. How can it migrate to the other host if it is exclusively activated ? How can i find out if a lv is activated exclusively ? How can i find out on which node it is activated exclusively ?
Thanks.
