If the NetApp has block-level snapshots, that would be an excellent

From what I've heard, apparently NetApp has LUN-level snapshots.
That sounds promising!
[root@va03 ~]# gfs_tool freeze /gfs
gfs_tool: unknown mountpoint /gfs
[root@va03 ~]# gfs_tool list
3501862912 gnbd0 foo:a.0
[root@va03 ~]# gfs_tool freeze 3501862912
[root@va03 ~]# gfs_tool unfreeze 3501862912
I see how it is. It worked stably!
By the way, sometimes I get warnings from gfs_fsck for snapshot-LV,
even though I froze GFS before doing lvcreate -s.
For example, the followings are. Is this usual thing?
# gfs_fsck -y /dev/vg0/lv0ss0

The cluster components are changing radically in CVS head and don't all
work together yet. So, you need to checkout code from the RHEL4 or FC4
cvs branches.
I see, I will try with FC4-test3 from now.
Thanks!
