ReadyNAS 104 Disks thrashing

Question

I have a ReadyNAS 104 at home and I often only access it in the evenings. Normally the unit has gone into standby mode and there is no disk activity. Almost every time I go to use my PC the disks are asleep. Often whilst I am using my PC the disks go to sleep as they are not being accessed.

However, I recently upgraded the firmware to version 6.10.10 and now there is constant disk thrashing activity. The unit never goes into standby. This is happening almost 24 hours a day.. Very occasionally there will be a break of a few minutes and then the disk thrashing restarts.

Since installing 6.10.10 I have continued to use the unit as normal and there has been no significant increase or decrease in the amount of data held on the NAS drive. The logs show Snapshots and Backups are done just after midnight and are complete in a few minutes. The logs show no other activity and I have no idea what is going on.

The unit has 4.6TB of 10.9TB free. There is no antivirus or any other software installed on the NAS. If I disconnect the network cable and the USB cable to the backup device, the disks continue to thrash

I have tried rebooting the unit but this does not fix the problem.

I would be grateful if someone could you advise me how to find out what is going on and how to resolve this issue and stop the constant disk thrashing.

Start by downloading the log zip file, and looking in there for any floods of errors.
&nbsp;
Did you have ReadyCloud enabled at some point in the past?

Hi&nbsp;Thanks for your help.&nbsp;I have downloaded the logs. I had a quick look at the biggest ones, but nothing obvious. The logs go back many years as I have never cleared them. The biggest log is where is msmtp log where the system is trying to send me emails saying backups successful but cannot authenticate. I will remedy that.&nbsp;Do you think the best approach might be to clear the log files so I can see what is happening more easily from now forwards.

I wouldn't clear the logs.
&nbsp;
Have you looked in systemd-journal.log?&nbsp; I am wondering if there are leafp2p errors in there.

Hi&nbsp;Amazingly,today the disks have now quietened down and gone back to normal.&nbsp;I have checked this log and there are many many errors such as these when the disks were thrashing&nbsp;Nov 12 16:46:29 NRN1 minidlnad[29030]: monitor_inotify.c:131: error: inotify_add_watch(/data/Music/snapshot/c_2023_01_07__00_00_25/Led Zeppelin) [No such file or directory]Nov 10 00:56:40 NRN1 minidlnad[15566]: [mpeg2video @ 0xb5486cc0] Invalid frame dimensions 0x0.Note the old date on the snapshot file.&nbsp;&nbsp;There are also many errors related to sending alerts to my yahoo.co.uk address. I have put in the correct address and it comes back with an error when you try to send a test message. I still cannot get this to work&nbsp;The from address in the advanced section is the same as my email address. So I changed this to a different address and it still does not work.&nbsp;Thanks for your help.

It should be.
&nbsp;
My own system uses smtp.mail.yahoo.com for the SMTP server, with the SMTP port set to 465.&nbsp; Use TLS is also set.
&nbsp;
Note you do need to go into the security page on your yahoo account, and generate an app password for your readynas.&nbsp; then use that password in your ReadyNAS email settings.

&nbsp;

Thjis one is because one or your media files is corrupted, so the DLNA scanner isn't able to get the metadata from that file.&nbsp; upnp-av.log might have more information.

Note the old date on the snapshot file.&nbsp;
&nbsp;

If you are running the "Smart" snapshots, I suggest switching to "Custom" and set a specific retention period.&nbsp;&nbsp;
&nbsp;
You might also want to go into the music folder in the web ui, and manually delete old snapshots that you see.&nbsp;
