Full Discussion: ZFS - whole disk Vs slice

ZFS - whole disk Vs slice
we have a ZFS file system that was created as a pool of just one disk (raid on a SAN) when this was created it was done as a whole disk, and so EFI label.

now we want to mount this file system into an LDOM.
my understanding of how ldom's and disk works this is that we can only do this as a slice.
the data looks to be all OK, but could this become an issue down the track?

so for example:

on the old server
Code:
zpool create testpool c0t600508A400070E320002200100170000d0
zpool export testpool

on the new server (control domain)
Code:
ldm add-vdiskserverdevice /dev/rdsk/c0t600508A400070E320002200100170000d0s0 volz@primary-vds0
ldm add-vdisk vdiskz volz@primary-vds0 ldom1


and then in the ldom (ldom1)
Code:
zpool import testpool


this is a 9TB file system , so we don't really want to have to copy all the data to a new 9TB file system.

mkqdisk

mkqdisk(8)						      Quorum Disk Management							mkqdisk(8)

NAME

       mkqdisk - Cluster Quorum Disk Utility

WARNING

       Use of this command can cause the cluster to malfunction.

SYNOPSIS

       mkqdisk [-?|-h] | [-L] | [-f label] [-c device  -l label] [-d [-d ...]]

DESCRIPTION

       The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.

OPTIONS

       -c device -l label
	      Initialize  a new cluster quorum disk.  This will destroy all data on the given device.  If a cluster is currently using that device
	      as a quorum disk, the entire cluster will malfunction.  Do not run this on an active cluster  when  qdiskd  is  running.	 Only  one
	      device  on  the  SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
	      RAID array is used for quorum disk redundancy).  The label can be any textual string up to 127 characters - and is therefore  enough
	      space to hold a UUID created with uuidgen(1).

       -f label
	      Find the cluster quorum disk with the given label and display information about it.

       -L     Display information on all accessible cluster quorum disks.

       -d     Increase debugging level.  Specify multiple times for more information.  Currently, specifying more than twice has no effect.
