Hi,

I definitely suggest you make a backup of each device superblock and
distribute it somewhere safe in the unlikely event two devices in a
mirrored array stop cooperating. The superblocks do come in handy from
time to time when they can't be acquired once problems happen.
Do you have any suggestions on how to do this?
The other thing is, if you're panicked, it kinda suggests no
recent
backup. I can't tell you how many sad panda faces I see on many lists,
including the linux-raid@ list (all things RAID on Linux but mainly
md/mdadm) and it's like, really no backup? The brutal response is, if
you don't have a backup the data isn't important.
I do have a backup, but it would be a pain to rebuild everything. It
would be a major inconvenience. No one really ever wants to go through
that.
Thanks,
Alex
