RN10400 Lockup after starting up - load average is very high
Here is what happened. Recently I upgraded to ReadyNAS OS 6.6.1 I believe it runs okay for approx. a week. Starting just couple days ago, the box is not responding. I am not able to access the Ad...
Thanks.
I use Linux, so it is a good news.
Anyway. I came across another discussion thread.
I took the idea. Boot my NAS into Read-only mode and followed the idea to remove the old snapshots. I don't even know there are 40+ snapshots created so far. I don't recall I set that up, so perhaps it is just from some automated scheduler.
Once I removed the old snapshots, "top" command shows the load average at approx 3-4.50. Even after I restarted the NAS normally, the load apparently stay at 5.00 or below.
So far, it has been up for longer than before (like 20+ min now). I will keep it on and see if it is back to normal.
However, as I mentioned earlier, the Out of Memory error does happen quite often with recent ReadyNAS OS. There is definetly something not right. Perhaps there is some memory leak or simply the memory footprint is too much for such model. I hope more bugfix and optimzation can be done soon.
Given the very small amount of RAM on board (and no way to add more), I do worry the stability of the system and really skeptical on using it for any important data. Even with a good backup, it is a hardship to restore the data. Yes, I well understood it is probably just made as a consumer grade NAS (IMO). Unfortnately, I do not have confidence on it at this point.
Thanks. I am cross my finger and hope it can stay up for a while. I only use it as the storage for my video streaming purposes, but I still want it to be stable.

BTW, is there some wy that the disks can be mounted and accessible from other "computers" like a PC? If possible, that could be faster than relying on the ARM CPU in ReadyNAS to copy data.
The disks use the btrfs file system, which is not supported in Windows. They can be mounted on if the PC is running Linux. There is one RAID recovery software package which can access the data from windows - ReclaiMe. It is quite expensive though, and is intended for recovery, not as a general purpose btrfs package.
