I'm getting what looks like a drive error filling up my log but I'm not well versed in this sort of thing. I attached the log but this is generally what I'm seeing: Nov  9 21:57:25 unraid kernel: BTRFS error (device sdb1): bdev /dev/sdc1 errs: wr 27433770, rd 21055357, flush 348255, corrupt 0, gen 0. It was all on the 9th and nothing beyond. Either it fixed itself or the log was full (which I was told it was full). Can someone help me.

Diagnostics are always preferred over syslogs.  I'm the not btrfs guy, so will leave that to others, but

You need to update to 6.6.5.  On 6.6.4, no scheduled tasks run (no notifications, etc)

Those are read/write errors, i.e., hardware problem, with SSDs usually a result of a bad cable/connection, start by replacing the cables, then run a scrub and keep monitoring for more errors.

I updated and rebooted. I took a look at the new logs and I don't see those errors. I'll let it run a bit and keep an eye on things. Thanks for the very quick replies Squid & johnnie.black.

You already had a lot of errors before the current boot, so it will likely happen again.

I took a look at the main page of my server and just noticed I only have one cache drive but should have two. It's not showing up anywhere else so I guess it is either a cable issue or the fact I bought a cheap no-name drive.
