Hi,
I want to take snapshots of a iSCSI devices from a target that hasn't snapshot/cloning capabilities (it's a Infortrend A16E storage array).
What method are you using to make snapshots/clones of iSCSI targets using Open-iSCSI + CentOS? What about using Open-iSCSI + LVM snapshots system? For example:
- Take a LVM snapshot in the initiator with "lvcreate". - Give read-only access to the backup server, for the same LUN/volume. - In the backup server, mount in read-only mode this snapshot. - Take a backup of this snapshot, using dd/tar/rsync for example. - Unmount the snapshot in the backup server. - Remove this snapshot from the host with "lvremove".
Is there any soft to make this? thanks! NOTE: It's a must, that device snapshots must be in other device.. not in the same target.
