Hi folks, one of my ReadyNas Ultra 6 devices keeps losing its password - admin and others.
Losing might not be the right word but symptoms are can no log in to the web interface using admin or any account.
Shares continue to work as do scheduled backups.
The only fix is an OS reinstall which obviously resets the password to default.
I've even (as a test) tried leaving it on the default password and after a random period of time (1 week/1 month..) log in access to the UI will be lost.
I can still telnet in to root using the admin password in all cases.
I'm running OS 6 (on both NAS boxes) with all latest official updates but this only happens on one of them.
I took the rash step of a complete factory wipe and rebuild but that has not stopped the problem occurring.
Just a thought as I type this question - could this be a battery issue?

The symptoms sound more like a PC issue than the NAS.
Have you tried
connecting both using the NAS hostname and its IP address?
ok sorry by incognito do you mean private browser?
Yes. Chrome calls it "incognito", other browsers use different terminology.
Basically I want to be certain that the browser isn't automatically supplying the wrong credentials. That can result in taking you to the password recovery page.
What exactly happens when the problem starts? Are you unable to reach the web page at all? If not, are you getting the account/password prompt?
If it isn't the PC, then it would have to be something specific to the apache webserver on the NAS (since other services work). But I'd expect rebooting the NAS would clear it in that situation.
Any chance your OS partition is full? If it is, you should have log entries saying it is. Once the OS partition is full, the NAS can't re-write configuration files, which can lead to a host of different, seemingly unrelated problems. An OS re-install does not clean up the OS partition because it doesn't know what you or an app might have put there and needs to stay,
I'm not sure what comprises just the OS partition but assuming everything but data
Using du command from root I get 6.4M ./bin 0 ./boot 8.0K ./dev 10M ./etc 33M ./lib 4.0K ./lib64 0 ./media 4.2M ./opt du: cannot access './proc/11837/task/11837/fd/3': No such file or directory du: cannot access './proc/11837/task/11837/fdinfo/3': No such file or directory du: cannot access './proc/11837/fd/4': No such file or directory du: cannot access './proc/11837/fdinfo/4': No such file or directory 0 ./proc 20K ./root 56M ./run 11M ./sbin 0 ./srv 0 ./sys 808K ./tmp 446M ./usr 2.8G ./var 0 ./mnt 7.0G ./apps 2.1T ./data 0 ./home 30M ./frontview
Try again with ssh. Make sure you log in as root using the NAS admin password.
Start with this command:
mount --bind // /mnt
This temporarily mounts the root folder as /mnt. The reason this is helpful is that there are several folders in the root (OS partition) that are "mount points" - where other file systems (including some folders in your data volume) are mounted. These make it hard to see exactly what is in the root.
Often a full root is caused by third-party apps you've installed on the NAS. So it would be useful if you gave us info on what apps (if any) you installed on the NAS in the past. You did say plex is installed now - it could have left behind some transcoding files.
BTW, in order to undo the mount at the beginning of this post, you enter this:
cd //
umount /mnt
Note the spelling of "umount" - it's not "unmount".
The plex servers built for ReadyNAS put the plexmediaserver in the apps folder - which is actually on the data volume (.apps). That prevents filling up the OS partition.
The best way to fix this is to uninstall plex, and make sure that var/lib/plexmediasever is fully deleted. After that, downgrade to 6.10.9 and reinstall using the build from the link above. Then you'd need to reconfigure plex and set up your media libraries again.
There is another path that is less work. That is to copy the plexmediaserver to the data volume (personally I'd put it in .apps there), and then delete the folder in /var. After that you'd create a soft link to the new location on the data volume. We can give you the commands if you want to try that path. This would eliminate the need to reinstall anything, but you could run into trouble when updating plex in the future.
Note it can be tricky to fully recover from a full OS partition, as config files in the partition can get corrupted (since they can't be saved). If that becomes an issue for you, the safest path would be to do a factory default, and set up everything on the NAS from scratch (including restoring all the files from backup). But we can cross that bridge later on, if we come to it.
I've moved my plexdata from var to the /data drive
I created a custom override file for plex pointing to the new location (google is a great tool)
restarted everything and plex seems to work
I ran the du size check and the /var folder has dropped to 91M
Rebooted the NAS
It's started ok and the shares still seem good
Plex seems to have vanished from the installed apps list - but is running (which obviously adds credence to your observation on an incorrect installation (although it was there before)
Plex is also missing from the list of available apps 😕
Also many of the GUI menus seem to have strange/different names
I'm still on 6.10.8 - is this an issue?
Question - can I /should I extend the system partition size ?
Avoid 6.10.10, as it will remove the ability to install apps. You can get rid of the update check on system->settings->update if you haven't done that already.
