Hi all,
I've setup a ticket 20624099 for this issues as well. What I've consistently seen with my new readynas 3200 12TB is freezing when we try and do heavy writes to it. I've had to have remote hands restart it twice, corrupting some volumes.
If it sit there and is rarely accessed or ready heavily, It doesn't lock up. There isnt anything wrong in the logs, so i'm at a loss.
Hey Jit,
Any update on this issue? When I got my ReadyNas 3200 unit a bit over a year ago I had this same exactly issue with two Win 2008 servers using a CSV with a iSCSI lun. Level 3 support eventually replaced my unit but can only guess that the drives were bad (they were going out rapidly an some of the drives had bad firmware which caused the smart errors to read in the millions). Now fast forward to now, I upgraded my host servers to 2012 and I started getting the same issue with the readynas locking up. It first happened when I tried to use the Replicate software to replicate the Luns to a second 3200. Level 2 support had no clue with my logs. I played around with my switch and NIC configuration making sure to turn on flow control, jumbo frames, separated the iscsi connections...and it lasted a week. All of the sudden over the weekend, the 3200 locked up and became unresponsive again. I added in the adapter dual NIC card thinking maybe spreading the bandwidth among 4 NICS instead of 2 on the NAS might help, it didn't. The unit locked up again. Finally I decided to ditch the CSV and moved all the VMs on to the local hosts and just used the NAS for file storage. Again it locked up.
I am ready to throw this unit out the window and really regret buying a second one for replication. Level 2 support seems to be clueless with the logs and they always make it so hard to escalate things to level 3.
Anyone else seeing the same thing? I asked around some of my buddies using other NAS/SAN devices, they never experienced lockups.
I have seen constant problems with hard crashing of Netgear 2100, 2120 and 3220 NAS devices since November of 2014 under heavy I/O load (backup). By hard crashing I mean the device is no longer reachable by any method from the network -- no iSCSI, no web GUI, no ping, and the device needs a power cycle to come back to life.
In the configurations I've been exposed to, all were mounting volumes under Windows 2008r2 or 2012r2 via iSCSI. All but one of the 2100s was "stabilized" to mostly reliable performance by disabling anything but NIC failover and disabling jumbo frames, but it's a noticable performance hit. I'm mostly convinced that jumbo frame handling broke in whatever changed in the firmware after approximately November, 2014 because I've seen at least one crash where there was no NIC teaming configured but jumbo frames was configured.
All environments are jumbo-frame friendly and run either Equallogic or Compellent storage via iSCSI and jumbo frames without issues.
Prior to November 2014 all of these devices (except the 3220, which hadn't been purchased) were very reliable and our go-to device for inexpensive backup storage. A couple of the 2100s had been used for several years without any issues.
Support wasn't that much help, and it's not hard to see why -- the 21xx devices produce near zero logging information of value. We did get the first 2100 replaced under warranty with the idea that a NIC was failing, but the problem came back and there was no escalation, and this one never stabilized even with NIC teaming disabled and jumbo frames disabled. It got replaced with a low-end Dell box running 2012r2.
