If I just used lvm2 and ext3, without cluster suite and GFS, I found that I can mount the lv and its snapshot at the same time. I just want the file system supports two features as below, but can't be found now. Extended on mounted its snapshot can be mounted at the same time Ext3 not support support XFS support not support Cluster suite/GFS support ??? Is that Cluster suite/GFS can support feature of the snapshot mounted at the same time above? Thanks. Operations of ext3 fs just listed below: #pvcreate /dev/sda /dev/sdb #vgcreate vg1 /dev/sda /dev/sdb #lvcreate -L 10G -n lv1 vg1 #mke2fs /dev/vg1/lv1 #mount /dev/vg1/lv1 /home/lv1 #lvcreate -s -L 2G -n snap1 /dev/vg1/lv1 #mount -o ro /dev/vg1/snap1 /home/snap1 *** It is OK! ***
