ReadyNAS 3220 Locking up after upgrading to 6.2
Hello
Ever 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:

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. - Sounds like you have fragmentation issues.
Can you send me your logs (see link in my sig)? - Log file sent
- That's some pretty strange top output. Can you try
# systemctl stop readynasd
before your next backup run starts, and see if you still get an issue? - Your logs zip file was removed from your email for policy reasons.
- OK resent lolg file. should go through this time.
