Hi list,

I must apologize for the random attachment I sent with the last email, it's about my sons schooling and nothing to do with vserver at all, it wasn't meant for his mum. If everyone could delete it I would be most greatful, and it would be good if it could be removed from the archives too.

I also am repeating the text of the mail I accidentally added the attachment too below, so you have a copy I don't mind people keeping:

I don't think you'll have any problems with this approach. Format your loopback device with a file system of your choice and off you go. I guess you would be able to move the tagxid data then, which I don't think an rsync does, though it's simple to recreate.

$rsync --numeric-ids /guestpath/ otherhost:/guestpath/

Has always moved hosts fine for me. There are disk space disadvantages to the loopback idea, and further you couldn't use the hashify functions to reduce disk space and memory use further.
