PS6000 Smart-copies to Samba Shadow-copy
Hi,
I am investigating a way to create shadow-copy for our file server and was hoping to see if someone was able to accomplish that.
Bascially, can I take snap-shots on SAN(smart-copies) and mount them along with the volume, in order to simulate a shadow copy for windows hosts. I ask because only SAN software allows pause and thaw snapshotiing on any type of volume.
Anyone done this before? Any feedback?
I am referring this samba guide and where it comes to snapshot and mount on the same volume.

Found info on Auto SnapShotting here.

This may not be related to Dell Equallogic but more related to Samba. I am posting here to get some feedback.

Ok. Let me elaborate more.
I am using RHEL6 x64 host and have installed Linux HIT v1.1. It works fine. I can take snapshots and mount them using "asmcli" commands.
What I am trying to accomplish is mount the snapshot right under the same volume and enable shadow copy for windows users.
== code ==
SNAPNAME=`date +%Y.%m.%d-%H.%M.%S`
VOLNAME='/fs/test-01'
asmcli create smart-copy --source $VOLNAME
mkdir /fs/test-01/@GMT-$SNAPNAME
asmcli mount smart-copy --latest --destination /fs/test-01/@GMT-$SNAPNAME
==end code ==
smb.conf
[test]
path = /fs/test-01/test
vfs objects = shadow_copy2
It is not working as intended. I am seeing if someone has been able to accomplish this
