RAID drives
The mail server that failed last week had two drives that were RAIDed. The machine should have still worked after one drive died. I suspect it may have been running in degraded mode with one dead drive for a while before it finally died completely.
We need to set up a cron job on the new machine that will check the status of the drives periodically, so if one fails we can replace it before things fail completely.
It looks like that should be fairly easy.
With a healthy system the command
# cat /proc/mdstat
should give results like
A degraded system will look more like:
Personalities : [raid0] [raid1] [raid5]
It should be easy to set up a little script that can run nightly or weekly and email Shawn and me if the mdstat changes.
This page has a lot of useful information about setting up and testing RAID.
I will eventually get around to my project of setting up a server at home that I can backup my laptop to across the network, and I'll want to use RAIDed disks to get some more practice with them.
The new home server can't happen -- financially -- until after the septic system gets rebuilt (the permit for that is finally ready, now I need to get the actual work scheduled). And it shouldn't happen -- practically -- until the reorganization of the study is more complete.
