RN104 crashed with kernal seg-fault or ???
HI, My RN104 stopped communicating and after I verified that it was ON but not answering I looked at the front display and all the unit said was do_exit+8d8. It was non-responsive to the power butto...
I won't know for a day or two. I'm refreshing my backup of 10.9Tb prior to trying the disk swap from 104 to 204 and will test later. Perhaps there's a post somewhere that could teach me about optimizing the 204 on Jumbo frames in case it too has limitations?
Of course if if crashes, that is a bug not a limitation.
Performance gains for jumbo frames come from the reduced packets-per-second processing in the devices (both the PC and the NAS). They aren't more efficient for the network itself (network jitter actually will go up a bit because of the larger packet size).
The only way to see how much gain you get is to measure performance (in both directions) with JF on and off. With some equipment JF actually hurts performance.
General rules:
You should check your equipment NIC configuration and make sure the MTU is set to match the device with the smallest MTU size.
You shouldn't use JF if you have a mixed fast ethernet/gigabit network.
You should confirm the path MTUs with ping after you have JF set up, just to make sure the JF packets are being delivered without fragmentation.
Thanks StephenB
A bug is a bug!
On the other front: As it happens I have an otherwise all GigE, MTU 9000, dual NIC network for about a half-dozen systems(NASs and PCs) except on single NIC NAS. I'll have to do more investigating on the xfer rates and best settings as time allows this week.
Ultimately learning if the Annapurna can handle Jumbo's and/or teaming and such will matter to me. Maybe I'll better see why the other brands of NAS units I have are more robust or then again...
I use LACP teaming on my main NAS (a pro-6), but not the RN102 or RN202. Both the newer NAS are for backup, and only rarely see multiple data flows.
In general I think the RN202 is fast enough to benefit from teaming (as it will deliver 100 MB/s on a single gigabit interface). But my RN102 won't go faster than about 70 MB/s, so I don't much point to configure teaming with it.
I'm ok with my current LAN performance, so I've left Jumbo Frames disabled. Most of my devices will run it, but the max MTU varies, and it didn't seem worth the trouble.
Using both teaming and Jumbo Frames isn't a common configuration we see with the 100 series. Indeed in the past before we released our ReadyNAS OS 6 models we didn't support NIC teaming on home models as there is typically limited benefit in a home environment.
If you're looking to exceed gigabit ethernet performance then e.g. the 210 series or better yet a business model such as the 516 would be the way to go anyway.
I have the same problem, my RN104 does not reboot anymore and I have to pull the plug after every shutdown!
Can some please explain to me how to fix this??? Or do I need to throw it away?

Please open a new thread, with more specifics on the firmware you are running, what apps you have installed, and what failure mode you are seeing (is it a kernel segment fault or something else???),
