Hi everybody,
I am trying to take snapshot of a particular iscsi disk mounted inside the guest operating system. I have created my own snapshot feature for that.
Could someone please suggest the better choice for stopping read/write operations on disk out of the two to take snapshots, or if you have any better solution,
1) freeze filesystems ( using domfsfreeze ) and then take the snapshot or,
2) suspend the VM ( using virsh suspend ) and then take the snapshot
And, before taking the snapshots what other operations should i perform ( like sync or flush buffer ) for a consistent snapshot.
Any help would be greatly appreciated.
Best Regards,
Payes
