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.

You have a huge amount of metadata on your volume. Your volume is very fragmented.

You should lower the NFS thread count and run a defrag. You will want to disable your backup jobs temporarily to avoid those running during the defrag.

I did try enabling/ disabling the support option under settings a few times with no luck. will try the console option.

How do you lower the NFS thread count on the NAS? so no option under the NFS settings for shares.

Will run a defrag.

The NFS thread count so a global option for the NFS service under System > Settings > Services

How did the defrag go?

defrag completed after 12 hours. And it still locked up over night again.
Going to lower NFS count. I see it was set to 12 what do you suggest it be set to?

I tried to reduce NFS settings and get an error.

Can you send a fresh set of logs and the Config Backup?

It locked up again. After I rebooted the NAS I was able to change NFS settings. I lowered it to 4.

Still locking up every night with 4 NFS threads set in settings.

You still have a huge amount of metadata on your data volume. This indicates you have a lot of fragmentation. The high NFS thread count was likely related to this.

Sounds like the best solution would be to backup your data, do a factory reset (wipes all data, settings, everything), configure your shares appropriately and a low NFS thread count and restore your data from backup.
