if you were NOT monitoring for drive failures, you probably had a dead
hda for the past 5 days .. and i finally gave up when you noticed
- you will not notice that hda is dead as hdc will continue
to work in degraded mode ... but no copy of it on the other disk
i guess if hda has file1, file2, file3, file4, file5
and if hdc has only file1, file2
when you plug in a new replacment disk ... raid1 will
"properly resync" things for you ... but...
when does new raid1 erase file3, file4, file5 from hda
or when does new hdc raid1 add file3,4,5 to hdc
both disks is supposed to be identical in data
