Script for offsite storeage of RAID info needed for recovery

Script for offsite storeage of RAID info needed for recovery

[Krzysztof Adamski]

Reading about the heroic achievements of Neil to recover broken raids
for people it is obvious that before a RAID has problems good info needs
to be provided. Since usually that information is required after the
fact, I'm looking for a script that I could run periodically on my
computers that would collect all this info and send it someplace safe
off-site.

Is there a script that I could run from cron that would collect all the
needed info for a recovery of a broken raid and mail it off-site?

If there is nothing like that, then I can try writing it as long as I
could get the list of commands that would give me all the needed info.

Thanks,
K

Hello, Krzysztof

I'm running the following little script as a cron job every night. It
gives you:
1. the contents of /proc/mdstat
2. mdadm --detail for each md device listed in /proc/mdstat
3. mdadm --examine for each member device listed in /proc/mdstat

- -----8<----------8<----------8<----------8<----------8<----------8<-----
#!/bin/sh

cat /proc/mdstat

for md in $( cat /proc/mdstat | grep '^md' | cut -d' ' -f1 | sort ); do
	echo
	mdadm --detail /dev/${md}
	echo
done

for d in $( cat /proc/mdstat | "grep" -o 'sd.\?[0-9]' | sort ); do
	echo
	mdadm --examine /dev/${d}
	echo
done
- -----8<----------8<----------8<----------8<----------8<----------8<-----

Of course, this could be extended by also listing the models and
vendors of the component devices, but I've not done this for now.

I hope that helps,

Martin
