NAS to NAS Remote Replication Failure

[pah96]

Hello!

I have 2 Qnap NAS with problems by NAS to NAS replications since upgrade.

1) TS-410 (NAS1)
2) TS-412 (NAS2)

Both have been upgraded from 4.1.0 to version 4.2.6. First upgrade was performed an NAS2 (Backup) about 6 or eight weeks ago. Everything was running fine for 3 or more weeks. Two weeks ago the 2nd box has been upgraded. Ok so far.

Particularly the NAS to NAS replications during night hours get failed. I thought it was a temporary issue. I got this error 3 times now and I wonder why:

Code: Select all

 Server Name: NAS1
 IP Address: 192.168.1.3
 Date/Time: 2017/06/18 03:00:33
 Level:  Error
 [Remote Replication] (Sync) NAME failed: Authentication failed. Please check the user name and password.

I'm getting this only on one (last) of 6 jobs running nightly from 00:00 till 3 o'clock! The others running fine. I didn't change this jobs since 3 years and they have been running without any problem every day. This jobs are running on the back to back connection (2nd NIC) and separate IP addresses. Manually it works!

But there was a power outage some days after the 2nd upgrade. Because of my UPS the NAS stayed up. Except the switches. It took a little while before I recognized that the boxes "switched over" and set their default route (!) over the back to back connection that also stayed up all the time indeed after the switched network was up and running again. I changed this back and I seemes to work for some days.

But I think some connections from or to this separate IP network (only the NAS are in there) now going to the "new" old default route which I can see on my firewall. Connection which in theory could not be seen there.

Can anyone follow this issue? And can anyone give me a hint?

Best regards,

p.s. and no, I didn't reboot the boxes since their upgrades!
