HelloEver since we upgraded to 6.2 our RN3220 will lock up sometime over night when our backups are running. Requiring us to power off and on the device every morning.We were running 6.1.8 before upgrading with no issues. System will not let me rollback to 6.1.8 now.Running RAIDar is detecting device and displaying version as Support:64764. which maybe related to the issue?Any help into this issue would be great.Thanks

Sounds like your system put itself into tech support mode. Perhaps contact support?

No that indicates Remote Access SSH is still active.What software do you use for your backups?What protocol do you use for the backups?

We are backing up from CentOS 6.6 using rsync over NFS mounts.Also getting this message in logs after powering it back on: Volume 'data' health changed from 'Inactive' to 'Redundant'.Here is TOP info from when NAS locked up last night:top - 02:12:07 up 17:57, 1 user, load average: 6.97, 4.50, 4.23Tasks: 188 total, 14 running, 174 sleeping, 0 stopped, 0 zombie%Cpu(s): 0.2 us, 76.2 sy, 0.0 ni, 0.0 id, 23.4 wa, 0.0 hi, 0.3 si, 0.0 stKiB Mem: 3938476 total, 2933468 used, 1005008 free, 600 buffersKiB Swap: 5237756 total, 17160 used, 5220596 free, 1777080 cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 612 root 20 0 0 0 0 R 100.1 0.0 3:54.81 kswapd0 3961 root 20 0 0 0 0 R 100.1 0.0 2:41.04 nfsd26577 root 19 -1 1457m 38m 3200 S 100.1 1.0 4:01.64 readynasd 2988 root 20 0 0 0 0 D 2.0 0.0 3:05.81 btrfs-transacti 3964 root 20 0 0 0 0 D 1.0 0.0 4:49.70 nfsd 1862 root 20 0 0 0 0 D 0.3 0.0 314:23.13 md127_raid6 3955 root 20 0 0 0 0 D 0.3 0.0 3:34.47 nfsd27259 root 20 0 0 0 0 S 0.3 0.0 0:08.50 btrfs-endio-met 1 root 20 0 48040 2524 160 S 0.0 0.1 0:01.52 systemd 2 root 20 0 0 0 0 S 0.0 0.0 0:00.12 kthreadd 3 root 20 0 0 0 0 R 0.0 0.0 12:48.35 ksoftirqd/0 6 root rt 0 0 0 0 R 0.0 0.0 0:02.22 migration/0 7 root rt 0 0 0 0 R 0.0 0.0 0:00.07 watchdog/0 8 root rt 0 0 0 0 R 0.0 0.0 0:00.07 migration/1 10 root 20 0 0 0 0 R 0.0 0.0 0:02.46 ksoftirqd/1 12 root rt 0 0 0 0 R 0.0 0.0 0:00.11 watchdog/1 13 root rt 0 0 0 0 S 0.0 0.0 0:00.21 migration/2 15 root 20 0 0 0 0 S 0.0 0.0 0:07.99 ksoftirqd/2 16 root rt 0 0 0 0 S 0.0 0.0 0:00.09 watchdog/2 17 root rt 0 0 0 0 S 0.0 0.0 0:00.21 migration/3 19 root 20 0 0 0 0 R 0.0 0.0 0:01.35 ksoftirqd/3 20 root rt 0 0 0 0 R 0.0 0.0 0:00.17 watchdog/3 21 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 khelper 271 root 20 0 0 0 0 S 0.0 0.0 0:00.03 sync_supers 273 root 20 0 0 0 0 S 0.0 0.0 0:00.00 bdi-default 275 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 kblockd 454 root 20 0 0 0 0 S 0.0 0.0 0:00.00 khubd 463 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 md 568 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 rpciod 607 root 20 0 0 0 0 S 0.0 0.0 0:00.01 khungtaskd 678 root 20 0 0 0 0 S 0.0 0.0 0:00.00 fsnotify_mark 695 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 nfsiod 713 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 xfsalloc

What is your NFS thread count set to?Are you using bit-rot protection or snapshots for those shares?

Not sure on the NFS thread count what ever the default setting is I would guess.Bit-rot protection box is checked for each of the NAS shares.I upgraded to 6.2.1 beta with same results still locks up over night.

Just an update of what been trying to resolve.
We are still working on getting another server setup that we can use to backup the data from the NAS before we can try a factory reset.
I will be installing the 6.2.3 after are backup finishes running this morning.
Will send over new log file today.

I ran a Disk test came back with no errors
Ran a defrag
Ran a Balance
Was finally able to have a scrub complete.
We stopped all but one backup that runs over night and it still locks up.

defrag can't help you if the fragmentation is a result of snapshots. So you might try deleting all the snapshots you don't absolutely need, and then re-run the defrag.

We have no snaps shot. Disabled and deleted them before we upgraded to 6.2.*

Your smart_history.log does show that some disks are having errors. Perhaps a failing disk is causing the problem on your system?

Looks like those drives with errors are the 2 drives we already replaced in past month.

I have the same locking problem with nfs:

viewtopic.php?f=7&t=78073

I think we should start a new thread for NFS related problems.
Because I have already changed hard disks, resetted to defaults like you in the new thread we should explain what steps we have already done.
As a note for example my uptime has increased with more nfs threads.

Increasing the thread count will lead to a lot of fragmentation. Not a good idea in my view.

Have you tried changing to async?

Were at 8 NFS threads now. when we lowered NFS threads below 8 are backups would not run since it couldn't mount the NFS shares.

Can you try 6.2.3 beta 3: http://www.readynas.com/forum/viewtopic.php?f=154&t=78866

If you are willing you may also wish to consider 6.3.3 beta 3: http://www.readynas.com/forum/viewtopic.php?f=154&t=79670

We have a fix for premature snipping of logs so if your NAS locks up again a fresh set of logs may be more useful. If you send a fresh set of logs it would be helpful if you could state the rough time of the crash.
