Re: ISCSI disconnection issue in firmware 6.9.2
I upgraded to 6.9.2 yesterday and OMG I have been going down most of the day with iSCSI issues. If only I would have known about this problem I would have stayed on the older firmware (pre 6.6.x).
What are you using iSCSI for?
Any other services running?
Are you using any apps?
No apps.
Was using iSCSI for VMware.
Further diagnostics....
Switched over to NFS and same issue. Load comes on.... protocals drop. eth0 eth1 or both.
Switched over to alternate backup ReadyNAS and problem does not reproduce.
Factory reset this troublesome ReadyNAS and it hangs on boot at 90 to 94%. Still under warranty so I need to figure out next step.
So the firmware update was a coincidence.
You could have a failing disk.
Did you happen to download the logs before trying the factory reset? If so, have you checked smart_history.log?
Well after monitoring for a few days I've finaly been able to catch the 2nd unit doing the same thing. Bonded or not bonded my NFS share goes away briefly thus causing my VMs to temporarily pause.
No, no harddrive failures on either unit.
When I get a chance I'll gather the logs and send them on. At this point...... I have no stable ReadyNAS units; just a bunch of angry customers.
- You updated the system you sent the logs for from 6.2.4 to 6.9.2. You can see this in initrd.log.
Btw 6.9.3 is now the latest firmware.
The root volume is pretty full on this system.
I can see the app rsyslog is installed and running on this system. I suspect its logs are what’s using lots of space on the root volume
VMs would be better without snapshots and bit-rot protection.
Disabling quotas on the volume would also be advisable.
All in all if you have a good backup I think
Updating to 6.9.3
Verifying update successful
Factory default (wipes all data, settings, everything)
Reconfigure manually
Restore data from backup
Would be best.
If you’re using iSCSI LUNs then Thick LUNs also with snapshots and bit-rot protection disabled are the way to go for VMs.
