Hi, I'm trying to create a snapshot of a clustered LV of 3 nodes.
Acourdingly to http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Cluster_Logical_Volume_Manager/snapshot_command.html "LVM snapshots are not cluster-aware, so they require exclusive access to a volume. For information on activating logical volumes on individual nodes in a cluster, see Section 4.8, “Activating Logical Volumes on Individual Nodes in a Cluster”." So i try do activate the LV in one node only: [EMAIL PROTECTED] ~]# lvdisplay -C /dev/vg_clientes_so/root-app2 LV VG Attr LSize Origin Snap% Move Log Copy% root-app2 vg_clientes_so -wi--- 5.00G [EMAIL PROTECTED] ~]# lvchange -aey /dev/vg_clientes_so/root-app2 [EMAIL PROTECTED] ~]# lvdisplay -C /dev/vg_clientes_so/root-app2 LV VG Attr LSize Origin Snap% Move Log Copy% root-app2 vg_clientes_so -wi-a- 5.00G I the other 2 nodes i can see that the LV is not active: [EMAIL PROTECTED] ~]# lvdisplay -C /dev/vg_clientes_so/root-app2 LV VG Attr LSize Origin Snap% Move Log Copy% root-app2 vg_clientes_so -wi--- 5.00G [EMAIL PROTECTED] ~]# lvdisplay -C /dev/vg_clientes_so/root-app2 LV VG Attr LSize Origin Snap% Move Log Copy% root-app2 vg_clientes_so -wi--- 5.00G But when i try to create a snapshot in blade01 i get: [EMAIL PROTECTED] ~]# lvcreate --size 500M --snapshot --name snap /dev/vg_clientes_so/root-app2 Clustered snapshots are not yet supported. I'm using lvm2-cluster-2.02.16-3.el5 and RHEL5.0. Any ideas?
