[Unraid OS version 6.9.0-rc1 available]

So I upgraded just now, and after the reboot via the WebGUI (did not shutdown the server physically) unRaid came back up and said it detected an unclean shutdown and started a parity check. There are errors related to my nvme cache disk on the log, none of this was there prior to the upgrade, I believe.

 

Any idea what is going on?

I also had a similar result. Upgrade, reboot via WebGUI with no issues, and when it came back up it started a parity check.

That's the only entry I can find relating to it. No errors on my cache drive.

[[6.7.x] Very slow array concurrent performance]

I believe I'm experiencing this too. While on 6.7.2, when the mover runs, I had some big performance issues - notably with streaming things from an array drive on my LAN with Plex, but I also saw slowdowns with things like rsync. I am not sure what version this behavior started, because my mover generally only runs at 2am, however I transferred a bunch of data to my cache drive during the day recently, and manually started the mover and I noticed the issue (and so did my wife - "what's wrong with Plex?!").

 

I've not done any formal troubleshooting, but I did revert back to 6.6.7 and haven't experienced the problem again. I might have some time this week to experiment a bit more formally.

[disk spinup since ~ 6.6.x]

Anecdote, simply because I didn't do any rigorous testing, but just noticed it from my typical usage patterns - after 6.6.4/6.6.5 updates (not sure which because I applied them only 12 hours apart), spin down behavior seems like expected behavior.
