Today ... has not gone to plan.
Oddly, I think it started to go wrong on the way home, rather than while I was still at work (although I got no words written today on account of having to fight a series of administrative fires). I was happily cycling home in the dark, lights and high-vis on, everything more or less OK, when my rear wheel started to vibrate interestingly. I've been here before. I pulled over. Rear tyre, completely flat. Arse.
So I pushed my ironically-named pushbike home, and locked it to the mooring loop, as usual, and took the rear wheel off and brought it in with me, to fix the puncture. Since I'd just cycled/walked home, I took five minutes to spod on the 'net, and my music collection disappeared. The player stopped in the middle of a song, and when I went to check it there were no songs. No songs, no directory, nothing.
Troubling. I could swear they were here only a minute ago.
So, it seems the highly reliable RAID I built a couple of years back to store my stuff ... isn't so highly reliable any more. It's a 3 disk array, which means it can lose any one disk without losing any data. It's dropped one particular disk a couple of times recently, both times pretty soon after street-wide power cuts, so I figured it was a little tired, and planned to make backups etc. Real Soon. Unfortunately, now it's dropped that disk, and its brother... Array Failure.
RAID arrays spread the contents of a file across multiple disks to increase redundancy, so I don't even have a few of my many files intact on the remaining disk: I just have bits of the vast majority of my files. Those bits don't add up to a whole, in most cases. None of my skills with Linux seemed to be working, and I couldn't get it to rebuild.
Then, dwm turned up on IRC, and guided me through a six-hour rebuild that hasn't quite finished yet, but looks like it's going to work. Once it's done, I need to pull important things off that drive, then see what happens, I guess. I'm not quite sure what's wrong with the machine, but signs point to one of the SATA controllers going bad, which would be very annoying.
So, bit of a wakeup call there. A lot of my data is pretty insignificant, but I'd miss it if it were gone. So I must implement a Proper Backup Strategy in the soon-after...
I eventually solved the bicycle problem too. Patched the tube, went round the tyre to find the cause, found a 10mm shard of road-grit that had gone right through the tyre wall and slashed the tube. Yet another reason to hate snowy weather...
Oh well. The world turns, things happen, or don't, according to their own inscrutable timetable, and we all get slowly older. This is the way of things.
