so my rocketraid 1740 controller has 4 connectors .. i set it up with raid 5.
drive on port 4 failed, but it comes back online after computer reboots. array saw this, and started to rebuild the faulty drive.
i replaced it with new one.
i do not see a way to rebuild the array (in rocket raid bios screen the new drive was showing up as "new", but it would not let me add it as a spare)
in windows web based admin panel, i was able to initialize the new drive, and add it as a spare, but the array is showing as "disabled" and still no option to rebuild..
after rebooting, in raid bios screen, i see the drives as:
1-1: WD500AAKS 500 configured 1-2: WD500AAKS 500 configured 1-3: WD500AAKS 500 configured 1-4: WD500AAKS 500 configured (Spare)
but array is still "disabled" .. and when i view the array, the 4th drive (new one) is showing up as "missing" in the array, but in the devices it is showing as configured(spare)
when i plug in the old faulty drive, it goes back to "critical" state and automatically continues rebuilding.... but the drive fails shortly into it and array goes into disabled state..
i am thinking that now that the rebuild started, the remaining 3 drives are not capable to rebuild onto the new drive ?
little by little i am rebuilding the bad drive (it usually works for few hours after rebooting). Hopefully once i get to 100% i will be able to swap in the spare.
RAID5: never again
rebuild of "bad" drive finally finished and i was able to plug in the good drive. to my horror.. 2% into rebuilding the good drive, my raid controller started beeping and the 4th drive disappeared! So possibly it's the raid controller that is bad ?!
looks like the only thing i can do now, is get another nas and back up my data using RAID 1
