3 Drives down, Help!

[Jon Hardcastle <Jon@xxxxxxxxxxxxxxx>]

Hi guys,

I have been battling with intermittent drive drop outs that I have
been steadily pointing the finger of blame at the power supply; it is
old and is 450w powering 9 hard drives.

Unfortunately now I have been hit by a perfect storm of 3 of the 7
drives (raid 6) have been booted..

I am wonder what the best way to proceed is.. I want to

i) stop the array from auto assembling just in case one of the other
drive randomly 'fails' due to PSU or cabling issue.
ii) install a new power supply and check all cabling.
iii) Thrash the drives individually
iv) Assemble the array (read only?) so that any kickouts I can
confidence force the assemble
v) Adding the failed drives back in 1 of a time, presumably this is
better than adding multiple drives at the same time?

Any tips and pointers would be fantastic.

Thanks.
