6.10.5 not cleanly shutting down on Readynas Pro6
As part of a careful backup and verification process performed to upgrade from 6.9.4 to 6.10.5 on a ReadyNAS 626 and a ReadyNAS Pro6 I discovered that the Pro6 does not want to cleanly shutdown. Othe...
Just as a further note about my personal paranoia, I also updated a fresh USB backup of the entire server PRIOR to updating either of the machines....
Yeah, I know... An update takes me a few weeks... Sigh.
You might consider upgrading to 6.10.6. If you want AntiVirus, it's an essential upgrade. https://kb.netgear.com/000064345/ReadyNAS-OS-6-Software-Version-6-10-6
FWIW, I didn't have that issue with my own Pro 6 - it is on a power schedule, so a failure to shutdown would have been immediately apparent. What services do you have enabled? Are there any operations that might hold off a shutdown (for instance a raid resync)
Also - are you running the stock memory, or have you increased it?
I can say itr does not sound like a hardware problem. When shutdown doesn't occur because of a hardware issue, the OS normally unloads, but it just never shuts the unit off. Since your OS appears to still be running, that's likely not the case. That's not goiong to help you solve the problem, but hopefully does put you at ease a bit.
Have you tried issuing the rn_shutdown command from SSH?

Yeah, I don't think it is a hardware problem. Was running cleanly prior to the update and like you say because the logs are showing that it is still doing things 12 hours after issuing the shutdown command the OS is not crashing. Definitely acts like something is not unloading / terminating correctly.
I am not familiar with "rn_shutdown" does that just terminate the readynas tasks rather than a normal shutdown?
I have also not tried issuing a shutdown command from SSH which might be something interesting to try.
I did just try issuing a shutdown from the GUI while SSH was open. I got one ps -elf off and thought that the SSH was going to stay open and then the SSH stopped taking commands but did not close the window. Interesting.

Interesting that 6.10.6 is now available :-) I am a slow adopter for updates, watching the logs for a period of time to see if people are having trouble, then update the backup server, wait a while and then update the primary machine. I figure if the Pro6 is happy the 626 will definitely be happy!
I will probably try 6.10.6 and see if the behavior changes.
As far as services, the only thing beyond stock which is enabled is SSH. Definitely no RAID Resync in progress.
I am running 3GB of memory which if I remember correctly was adding a 2GB stick to the stock 1GB stick. I could change to two of the 2GB sticks if that becomes a problem.
It is interesting that a full scrub takes about 10 days on this box, the 626 with a similar amount of data takes about 4 days :-)
I will let you know if 6.10.6 solves the problem.
