ReadyNAS RN104 frozen during disk balance
Hi All, Having significant issues with my ReadyNAS RN104 after manually running a disk balance. ReadyNAS RN104 Firmware 6.10.4 (had only just updated to this version) 3x 3TB WD Red hard drives...
If you have not done a balance in a long time (or ever), it can take a while. But yours does seem to be stuck, as that is way too much time. Unfortuantely, that can be an indication of drive errors that could cause a problem if your re-boot. Given you have an RN104 and nothing is responding, I think it is more likely you've run out of memory, which is quite limited on the 102 and 104, or the CPU is at 100%. If it's memory or the CPU use, then a reboot is less likely to cause a problem.
If you have SSH enabled, you can try and get in that way. If you can't, then a reboot is probably the only solution. If you can, then see what the results of the top command are.
BTW, none of those maintenance activities were likely to solve your issue. They could be the cause of it if they were ongoing.
Thanks Sandshark
I do agree it seems like the freeze could have been caused my exhausting memory. Fingers crossed simply this and no further issues.
I decided to post here before just doing stuff. Someone with basic tech knowledge such as myself, can be easily lead to "just reboot it" as first troubleshooting. I wanted to make sure there wasn't something more I could do. Turns out 'something more' I could have done was back-up.
As per advice from StephenB , I'll attempt a reboot into read only mode and see where things lead from there.
All going well, there will be a new discussion to be had about the initial issue which was the continuous I/O noise from the unit.
Thanks once again.
