RE: [cobalt-users] RaQ4R Hard Drive failure

["Richard at Quarryhouse" <dns@xxxxxxxxxxxxxxxxx>]

Thanks. My RaQ seems to have 2 x 27GB drives. Does it matter if my replace
the master failed drive with the blank disk or should I move the OK
secondary onto the master and put the blank on the secondary?

I would love to backup. I have an identical 2nd RaQ. What is the simplest
method of backing this up please.

Richard

Can't you just get the first drive replaced? I would always replace
like-with-like where possible.

I assume its a RAQ4r - that originally had a 2 x 20Gb drives (1 of which
has failed) - not sure what will happen if you put a larger drive in - it
will probably work - just that you will only get 20Gb out of it.

In the manual is the specification for compatible drives (I also published
it here a few days ago) so should be ok just to power down the server -
replace the drive and power back up! Will take quite a while to re-mirror
though during which time performance will suffer.

Please (if possible) backup the server *completely* before you do this,
make sure you replace the right drive (no offence meant but I have seen
people re-mirror RAID systems and end up wiping everything!) and make sure
the new drive you are putting in is blank.

Thanks...
