i think this means it's time to order a new disk

does anyone know how bad this log message is on a scale from bad to … really bad ?

@orionwl yeah unless you have reason to suspect interface or power issues, it's probably the disk. after you get whatever you need off of the disk, you could try to confirm with the badblocks utility, but even if it comes up ok, it's best not to trust that drive very much going forward.

@mersible thanks !yes it's a pretty old drive so i suppose it was coming, good to get a heads up before it breaks downon the other hand it feels like a waste to trash a drive that's, for all intents and purposes, still workingbut i'll move the important data off it, just use it for what's easy to redownload

@orionwl it's medium bad. Only 3 marked unreadable so far, that's either 2 or 12 kbyte (depending if it's 512b or 4k sectors), so almost all of your data should be recoverable. But more than 0 marked bad, so very likely there is progressive failure underway. Copy data off that disk immediately if at all possible. Expect that additional unreadable sectors will be found during the backup process.

if you want a vision of the future, imagine the same linux kernel error message repeating every second—forever(looks like we've reached the next stage of disk failure)

@orionwl Guess I'm too late with recommending increasing the backup schedule/frequency and making sure you have a replacement disk ready.I don't know how bad your initially reported disk issue is, but afaik it's quite common that the disk detects issues, marks those sectors as bad and reports that ... and then just moves on (while no longer using those sectors). IOW, *afaik* these are normal events over the lifespan of a disk.But it would be useful to know which errors *are* critical.

@FreePietje thank youi have a replacement disk here, have been putting off replacing it (a bad idea maybe, but this kind of slow crash kind of intrigues me too), i have definitely increased backup frequency and moved important files off that disk 😅

@orionwl The increased backup frequency actually speeds up the disk's demise, but I don't know a better alternative.How did you detect it in the first place? Watching it 'crash and burn' does sound interesting :-) Especially since you know it's coming and can thus be prepared.But I actually don't monitor for such things ... which is pretty bad.

@orionwl nice! did you get a chance to run the badblocks utility on it? I'm curious if it had anything useful to say.

@FreePietje i saw those messages in `journalctl -f` while looking for something else(this requires smartd to be running, it will log when the state detoriorates)to see a lot of health/status information about a disk you can run `smartctl -x /dev/sdX` as root, but as you've seen it's sometimes hard to interpret

@orionwl Thanks :)"while looking for something else"And that is how I would spot such a thing too ... by mere accident ...

@orionwl Bonus points it if happens on boot.
