No spin down, defective kernel?

Post by DarkSchneider » Tue Apr 28, 2020 11:24 pm

I have a QNAP TS-431P, updated to firmware 4.4.2.1273. Not sure if was with this last one, or also previously (but short time ago) there is no more spin down, as there is always disk activity each short time.

Followed QNAP guide, detected some things like dhclient, so set IP manually and etc.etc. No spin down.

Well, I am not going to paste the script output because once I did all the stuff, I can summarize the output:
- Many jbd2.
- Less kworker.
- Few rsyslogd (usually followed by some or many jbd2 in a row).
- No other things, only the 3 already mentioned.
- In any case, no file indicated, only block numbers, so no log files should be involved.

Jbd2 is the ext journal process. Looking about this, I found that is a kernel bug:
https://bbs.archlinux.org/viewtopic.php?id=113516
That references to:
https://bbs.archlinux.org/viewtopic.php ... 17#p801017
I also killed the HAL daemon process, with no result, jbd2 continues to write and write all the time.

So I can only think that the current kernel is defective, making excesive use of jbd2, as mentioned in the 1st link.

I also noticed that the output has many "<7>" placed randomly, so seems there is some kind of problem.

Anyone with the same problem? I expect QNAP will take a look at it and solve it with a new firmware.

Have you created a support ticket for that? Otherwise QNAP will do nothing about it.

I am facing similar issues. I have created a support ticket and continuously discussing with support team.
They are asking me to do one test followed by another test but even after 2 weeks, they are not coming back with any solution.

**, then the only solution seems the usual, wait for a new firmware and cross fingers.

I have to add, that after many, many, many, and many writes, finally it spins down. But sometimes, and with all machines off, it eventually spins up by its own, apparently with no service accessing (like I said on the first post). Also have all auto updates check disabled, both system and App Center.

as a test disconnect your NAS from the network. let it go into standby. does it then still wake up. I asks as it maybe something else on you network (switch, router, DDNS(myqnapcloud or other services) accessing the NAS and waking it up.

I have a 463 as a backup nas and if its not backing up, then its in standby. It wakes up when HBS3 from the 473 tries to do a backup to it or if I try accessing the webgui,mount a drive, or I ping it.

Well, after some try that is not feasible. When disconnected, it even writes more to disk, wirtes and writes and writes...it seems it checks every 5 seconds if it logged about the network was disconneted, to be sure you will be noticed about it. Definitely the NAS have some stupid design issues so you can only cross your fingers and, if lucky, your HDDs will rest a bit.

unfortunately unless I know every aspect of your NAS, what apps and settings you already have enabled and use, I am merely guessing. sorry I cant help.

I suggest you log a call with QNAP. explain to them what you have done, and ask them to diagnose your issue.

Only using media sharing, with thumbnail generation disabled, also all logging that can be disabled, it was. As mentioned, already used the script for monitoring disk access, and, after all cleanup, only can see system (like journal) accesses, not services. All that is kernel and filesystem related, so in that case I think few can be done. All the support is going to do is repeat the process monitoring the services with the script, that is already done.

Thanks for supporting.
