hi,
to manage backups from Xen DomUs, I create snapshots from every guest.
They're all running under Debian Etch. No problem at all, normally, but
... see yourself:
My script creates only snapshots and mounts them, nothing more.

root@henrietta ~ # ls /media/backup/angelica-disk/dev/neko/

So, first question, why i have the name from a different volume
(hitomi-disk) in the dev from angelica?
root@henrietta ~ # ls /media/backup/hitomi-disk/dev/neko
ls: /media/backup/hitomi-disk/dev/neko: Input/output error
Why i get here an error?
any suggestions?
