I think that warning is a bit misleading/extreme. The damage only
occurs if you bring up one disk degraded, *and* then the other disk
degraded. In practice, this should never happen since usually someone
would notice the degraded event and take action to restore the missing
disk. The release notes should simply explain when the problem occurs,
and warn people to be aware of it and watch out for it. Maybe something
like this:
Activating a RAID1 array with only one disk, then activating the array
with only the other disk, then finally returning to normal operation
with both disks can cause the disks to be combined out of sync, leading
to severe data loss. You should take care to make sure that this
situation does not happen.
