Shadowset volume mount and dismount?

» close window

The Question is:

 
I HAVE A HOST BASED SHADOWSET DEVICE MADE UP OF 2 4.3 gB DISKS MOUNTED ON A
3-NODE CLUSTER.  AFTER FORCING A CRASH DUMP ON ONE NODE ONE OF MY HOST BASED
SHADOWSETS WENT INTO A MERGE STATE.  MY QUESTION IS CAN I DISMOUNT A SINGLE
MEMBER FROM A SHADOW SET W
HILE THE SHADOW SET WHILE IT IS IN A MERGE STATE?
 
THANK YOU...JOHN WIENCEK
 
 

The Answer is :

 
  If you want your data to be consistent on each volume of the shadowset,
  you will want to wait for the merge to complete and dismount the entire
  shadowset, remoting those volumes you wish to remain online.  If you
  are not concerned about the contents of the volume that is the target
  of the merge, or if you are otherwise willing to risk inconsistencies
  across the shadowset volumes, you can dismount individual volumes without
  dismounting the entire shadowset.  If you remove the merging volume and
  remount it, the volume will be the target of a copy -- dismounting and
  remounting the volume effectively converts the merge into a copy.
