I still haven't learned my lesson about power failure and software RAID

A while back I suffered a power failure in my townhouse that screwed up aenea’s software RAID volume. I swore I’d put her on an UPS so it wouldn’t happen again. And yet, last night, it did.

So, this morning (a Sunday morning during which I was looking forward to beating ejabberd into submission) I awoke to find my file store screwed to the wall. I frantically searched about for the grime-encrusted floppy where I put my custom-compiled HighPoint RocketRaid driver for FreeBSD 6.0-amd64. I finally found it and was about to boot it, only to run across my post from the last time it happened, which refreshed my memory on the coping mechanism and the glorious absence of using an external driver floppy therein.

Now the file system damage has been repaired (or at least isolated) and I’m running the full fsck -p on all the filesystems to be sure all is well. insha’allah there will be no serious damage.

This time, I really mean it. I’m putting aenea on an UPS. Really.

It turns out my memory wasn’t faulty; I did put aenea on an UPS. Trouble is, her huge power supply and array of power-hungry hard drives result in a power draw somewhat in excess of what my humble little UPS can dish out. So, yet again, I go to Best Buy, hat in hand, taking back all the shit I talk about big box retail tech stores, to get a new UPS with enough juice to power aenea. Oh well.
