Steps taken:-
1. Snapshot an existing ZFS filesystem.
2. Created clone from snapshot.
3. Updated files on cloned ZFS filesystem.
4. Snapshot of cloned ZFS filesystem.
5. Attempted to promote clone ZFS and get error message. See below.

I created a zpool and in it there is a zfs volume. I used that to backup data on another server using ISCSI. Now I have the data and want to take a snapshot so that I can view it on another machine that is not in production.
Here is what I have done

I have installed Solaris 11 Express on my server and want to set up automatic backuping using zfs snapshots. In the backup script I need to find out the name of the last snapshot of the given filesystem (in order to refer to it as the startpoint of an incremental backup). What is the best way to do...

Dear Srs,
I have a Linux server (linux01) booting from SAN with a volume in a Nexsan SATAbeast storage array (san01). The disk/volume has four ext3 partitions, total size is near to 400GB, but only 20-30GB are in use.
I need to move this disk/volume to another Nexsan SATAbeast storage array... (0 Replies)
LVDISPLAY(8) System Manager's Manual LVDISPLAY(8)NAME
lvdisplay - display attributes of a logical volume
SYNOPSIS
lvdisplay [-a|--all] [-c|--colon] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--maps] [--nosuffix] [-P|--partial] [--units hHbB-
sSkKmMgGtTpPeE] [-v|--verbose] [--version] [LogicalVolumePath [LogicalVolumePath...]]
lvdisplay --columns | -C [--aligned] [-a|--all] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--noheadings] [--nosuffix]
[-o|--options [+]Field[,Field]] [-O|--sort [+|-]Key1[,[+|-]Key2[,...]]] [-P|--partial] [--segments] [--separator Separator] [--unbuffered]
[--units hHbBsSkKmMgGtTpPeE] [-v|--verbose] [--version] [LogicalVolumePath [LogicalVolumePath...]]
DESCRIPTION
lvdisplay allows you to see the attributes of a logical volume like size, read/write status, snapshot information etc.
lvs (8) is an alternative that provides the same information in the style of ps (1). lvs is recommended over lvdisplay.
OPTIONS
See lvm for common options and lvs for options given with --columns.
--all Include information in the output about internal Logical Volumes that are components of normally-accessible Logical Volumes, such as
mirrors, but which are not independently accessible (e.g. not mountable). For example, after creating a mirror using 'lvcreate -m1
--mirrorlog disk', this option will reveal three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.
-c, --colon
Generate colon separated output for easier parsing in scripts or programs. N.B. lvs (8) provides considerably more control over the
output.
The values are:
* logical volume name
* volume group name
* logical volume access
* logical volume status
* internal logical volume number
* open count of logical volume
* logical volume size in sectors
* current logical extents associated to logical volume
* allocated logical extents of logical volume
* allocation policy of logical volume
* read ahead sectors of logical volume
* major device number of logical volume
* minor device number of logical volume
-m, --maps
Display the mapping of logical extents to physical volumes and physical extents. To map physical extents to logical extents use
pvs --segments -o+lv_name,seg_start_pe,segtype.
--columns | -C
Display output in columns, the equivalent of lvs. Options listed are the same as options given in lvs (8).
Examples
"lvdisplay -v /dev/vg00/lvol2" shows attributes of that logical volume. If snapshot logical volumes have been created for this original
logical volume, this command shows a list of all snapshot logical volumes and their status (active or inactive) as well.
"lvdisplay /dev/vg00/snapshot" shows the attributes of this snapshot logical volume and also which original logical volume it is associated
with.
