I have two systems which are running (virtually) identical vinum mirrored configurations, and I'd like to back them up by copying an entire disk from each system to a third system, such that if one of the first two systems died completely, I could switch the disks around in the backup machine to replace it. ------------------- ------------------- | a | | b | ------------------- ------------------- | | | | ----- ----- ----- ----- |ad0| <-----> |ad2| |ad0| <-----> |ad2| ----- vinum ----- ----- vinum ----- | | | | | | ---------------- -- | backup to standby | | | | | v ----- ----- (a:ad0) |ad1| |ad2| (b:ad0) ----- ----- | | ------------------- | standby | ------------------- | ----- |ad0| ----- (system) The problem is that I'd like to at least validate that the filesystems on the backup disks pass basic tests (fsck, mount, ...) but since the systems have been setup identically, I'm concerned that the vinum definitions copied to standby:ad1 and standby:ad2 will "clash", causing one of the backups to get nuked. Any thoughts, anyone?
