LOLA has suffered the same fate as ZOOMER, and had to be forcibly rebooted...
I was in the DC earlier this morning to pull down some old drives, as there is no need wasting electricity and generating heat by spinning the old 18GB drives...
Everybody asks, if you have Hot Swap, why do you have to take down the server... Well this morning, I gave it a shot, since I was not plugging a new one in, but rather pulling an old one out...
Once again, I am reminded that the Adaptec SCSI driver, still does not gracefully handle any device removals/additions to the SCSI bus... The only thing it gracefully handles is if a device fails... It will gripe and moan for a couple minutes before signalling up to the RAID layer that "Hey, this drive just died - you might want to do something about it"...
Of all the Linux Enterprise touted features, they really need to dig deep into the SCSI layer and give it a good overhaul... I believe they have done just that with Linux 2.6, but I would still be highly skeptical of it...
LOLA's downtime spanned from: 7:47 to 8:03
My apologies for the resultant downtime this drive removal caused...
