Using two mirrored drives separately

[Leonid Bloch]

Hi,

I am wondering: if I set up btrfs on two identical drives, with data
and metadata mirroring, will it be possible to use these drives
separately later on? Will just one of these drives work as a regular
btrfs-formatted single drive if connected to a different machine?

Thanks ahead,
Leonid.

If by this you mean btrfs raid1, then yes, they will work this way. Just
both of them will have missing device and, afaik, wont mount without
-o degraded. But then you can rebalance to notraid1 or add another disk
and replace missing devices on new machines.
