Perhaps annoyingly, somedays it boots every time. Then I get a day when
it wont boot at all.

I never considered the possibility that mirrored mode might be a
contributing factor.

Wonder if it is a matter of one drive being OK, however it is random
which drive it is; it will boot if the drive referenced in /etc/fstab is
the drive that is OK.

I created it on a single drive, then followed the instructions to mirror
it in RAID1 mode on the other drive.
