RE: [cobalt-users] raq 4 raid failure



I may be wrong, but the two hard drives are not the same size and thus
should not be able to mirror.
Please correct me if I am wrong.  I also know from other posts that the
original hard drive is no longer available.  What are we to do?  (No
joke)  Do we have to pull the good drive and copy it to another drive with
something like drivecopy and then put two identical drives back in the
Raq????

Raid at least worked like it should have though the Cobalt Manual is WRONG.
The manual states that the GUI will tell you which drive failed...it does
not.
The primary hard drive is the one on the left. It is plugged into the black
horizontal
IDE socket. The backup raid drive is on the right and is plugged into the
top vertical RAID
IDE socket which is bright blue. The machine rebooted for unknown reasons
and the primary
drive failed on the reboot. The disk light on the front panel came on,
active alert mailed
off a disk failure notice and the gui alert went red. After replacing the
drive the disk light
went back to normal.

The drives are as close as I can get them...I couldn't find the exact
identical
Seagate model. The Raq4 came with 2 Seagate 20.4 GB UT10  ST320423A 's which
are ATA66.
My supplier only had the ST320413A drives from the U5 series which are
ATA100. Their size is slightly different:
The oem is 20.4 GB and the new drive is 20.2.

>From what I've read 2 different sizes do not stop raid mirroring
completely...just up to the capacity of the
backup drive. On this particular machine there is ALWAYS 17GB's free so
would .2 gb really matter?

If Cobalt Raid really requires absolutely completely identical disks than
the only solution to get RAID back would be
to start over with the restore CD which kind of defeats the purpose of
having raid.

For those who are interested this drive failure was on a 1 year old Raq
4r....extremely LIGHT load.
No Seagate warranty on the drive since it's a Cobalt OEM and Cobalt requires
you to ship the whole server back for
warranty replacement.

The replacement drive I installed comes with a Seagate 3 year warranty.
