ReadyNAS Ultra 6 "hangs"

[krid]

My trusty ReadyNas Ultra 6 has stopped working 😞 It is booting fine but it seems anything needing i/o is stuck in an endless loop. The GUI prompts for username/password but after that it keeps loading "forever". SSH login is working and I can do some commands like tail syslog, but when tailing more lines than default it also hangs. I can list directory contents with ls but ls -la also hangs. Mdstat shows all (six) disks online and I've also ran a diskscan from the bootmenu which was OK. I've hooked up a monitor but don't see anything strange. Finnaly I've tried different RAM but the results are the same. The thing I haven't tried is the factory reset from the bootmenu because I had some custom apps on it I'd prefer to keep. I don't think these are the problem because they've been running fine for years, but willing to try if anyone thinks it's worth trying.

Does anyone have any tips or suggestions on how to solve this?

Probably it just got caught in the automatic spam filter.

The OS is fuller than usual, but not dangerously so.  With no apps installed it is usually about 20-25%

Does ls -la hang in the OS partition, the C volume or both?

It might be worth trying an OS reinstall via the boot menu.

What firmware are you running?

Did you check for a full OS partition?

Thanks for responding!

It's running RAIDiator-x86 Version 4.2.31

OS partition is OK?

Yes, it was hanging on both partitions. Strangly enough I was able to copy the custom apps to USB so I decided on your suggestion to do an OS reinstall. Now it's fixed. Thanks for help!
