Move Disk Compressed

[masterdaweb]

Hi,


I'd like to know if is there some way to move disk and compress it by command line before moving.
, Because it's moving an almost clean disk with 150 GB size and taking too much bandwidth

If I interpret "too much bandwidth" correctly you mean "move disk remotely", then the disk is copied via SSH, so you can use SSH compression if you enable it (man ssh_config).

Otherwise, you can always backup the machine with the fast compression and restore it on the new storage. You can get better compression rated with better compression programs, but you'll need more time and the normal LZOP is just fine for backup & restore and will compress empty space also very well. This should be the fastest method.

I just reread my answer and this is only true for moving the VM across host boundaries, not moving from local disk to nfs for example. So you should stick to backup & restore for that purpose.

Yes, the purpose of this topic is that I'm Moving Disk over Hosts.

I was planning a bash script to compress with LZOP (as you suggested), but I came across with the situation that I can't turn off my customer VM for a Disk Compress moving.

I think the only possible thing that I can do is turning on SSH Compress (As you suggested)
