Well with clvm sort of ... with non clustered lvm it doesn't matter what fs you are using and it is possible to make a snapshot - it would also help mounting the snapshot of an ext4 partition on different node too with clvm you need to "activate the volume exclusively and then create the snapshot", but not sure if you can later mount the snapshot on another node > -- > Linux-cluster mailing list > Linux-cluster@redhat.com > https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster mailing list Linux-cluster@redhat.com https://www.redhat.com/mailman/listinfo/linux-cluster
