I recently resurrected one of my ReadyNAS 4 units. The web interface is spotty as all get out - web service seems to hang after a few hours, cannot change IP address via the UI, etc. I checked another of my units and it is running 4.2.30 and is rock solid. I can only assume the latest 4.2.31 is buggy. Any thoughts on how to downgrade? Is this even an acceptable action? -Dave

You can downgrade, but the only change in 4.2.31 was a patch for a serious security vulnerability. Bug Fixes and Enhancements Fixes for Samba CVE-2017-7494. I think it's quite unlikely that this patch is the cause of your problem.

Actually, right now, I cannot even get into the web admin at all: http://imgur.com/tycXA0S There is something definitely broke with the web server. I was actually hoping to install the SSH module so maybe I could telnet in to review logs, etc. but I see no way to do that now either. Thoughts on how to fix this? -Dave

Hello Dave, You can set the NAS on telnet(tech support mode) through the boot menu to access it via telnet locally. Please click here for guide on how to access the boot menu of the NAS just make sure to select the exact model number of your NAS since each NAS has different way to access the boot menu. Since you have just resurrected the NAS, I assume there is no data on it. You may start with an OS re-install to reflash the OS or start with a factory reset. Welcome to the community!

Yup! I didn't realize "tech support mode" was also telnet mode. I am in - now I just need some advice as to what to look at to see my Frontview is failing. I am fairly UNIX literate, so if you can direct me to the proper location for logs, etc. I can check things out. So far I've mounted the partition and have looked around at folders like the var/logs/frontview but have not seen anything obviously wrong (like huge log files, etc.) -Dave

There is the "brute force" approach where you just do a factory reset and rebuild the NAS from scratch. Similar to re-imaging a PC. Easy to do, but takes a day or so to resync, and then you need to reconfigure and reload the data. If you have no data on the NAS you need to extract, and it is being "resurrected", then I recommend that approach. BTW, it might be possible to install OS-6 on the NAS. What model is it? The OS reinstall won't help if it's due to a full OS partition - but if the cause is a mildly damaged OS, it might. Since you have shell access, start by seeing if the OS partition is full before looking for log files to truncate (df . -h). Look at free inodes also (df . -i)
