Howdy, As some know, I recently moved a LOT of data around. Seems to have stressed one of my drives. I got a email from SMART reporting a error. It's info:
The following warning/error was logged by the smartd daemon: Device: /dev/sdd [SAT], 1 Currently unreadable (pending) sectors The following warning/error was logged by the smartd daemon: Device: /dev/sdd [SAT], 1 Offline uncorrectable sectors This is from smartctl.

It moved to #5 plus added 3 or 4 it seems. According to google results, it should be fine for now. Still, a replacement drive is on the way and I've unmount the drives for that LVM. They still spinning and running a selftest but nothing else should be accessing them. This is also from the selftest.

The whole test doesn't take that long, or shouldn't anyway. I restarted it shortly after that. I might add, the test did take many hours longer than it estimated which from my past experience is quite odd. It's usually pretty accurate. Still, it completed and shows it passed, just has a boo boo on it. I also did a file system check it fixed a couple problems and a bunch of little things I see corrected often on bootup. Something about length of something. Seems trivial. Given the low number and it showing it corrected that error, and then passed a short and long test, is this drive "safe enough" to keep in service? I have backups just in case but just curious what others know from experience. At least this isn't one of those nasty messages that the drive will die within 24 hours. I got one of those ages ago and it didn't miss it by much. A little over 30 hours or so later, it was a door stop. It would spin but it couldn't even be seen by the BIOS. Maybe drives are getting better and SMART is getting better as well. Thoughts. Replace as soon as drive arrives or wait and see? Dale :-) :-)
