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? Regards Steve

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. Then you could try du -d1 -h /mnt to see how full each of the subfolders are. On my own RN526, I see this: 6.4M /mnt/bin 0 /mnt/boot 24K /mnt/dev 12M /mnt/etc 0 /mnt/home 33M /mnt/lib 4.0K /mnt/lib64 0 /mnt/media 4.7M /mnt/opt 0 /mnt/proc 40K /mnt/root 0 /mnt/run 11M /mnt/sbin 0 /mnt/srv 0 /mnt/sys 0 /mnt/tmp 331M /mnt/usr 538M /mnt/var 0 /mnt/mnt 0 /mnt/data 0 /mnt/apps 30M /mnt/frontview 964M /mnt Your problem appears to be in /var, so maybe try again with root@NAS://# du -d1 -h /mnt/var 0 /mnt/var/opt 109M /mnt/var/backups 0 /mnt/var/local 60M /mnt/var/log 4.0K /mnt/var/spool 0 /mnt/var/mail 53M /mnt/var/cache 287M /mnt/var/lib 0 /mnt/var/tmp 4.0K /mnt/var/www 8.0K /mnt/var/netatalk 0 /mnt/var/cores 0 /mnt/var/ftp 29M /mnt/var/readynasd 538M /mnt/var root@NAS://# 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".

You can then repeat the process, and look a level deeper. root@NAS:/mnt/var/lib# du -d1 -h /mnt/var/lib 0 /mnt/var/lib/initscripts 12M /mnt/var/lib/dpkg 0 /mnt/var/lib/nut 0 /mnt/var/lib/misc 0 /mnt/var/lib/urandom 0 /mnt/var/lib/dbus 0 /mnt/var/lib/insserv 0 /mnt/var/lib/update-rc.d 4.0K /mnt/var/lib/mdadm 43M /mnt/var/lib/apt 12K /mnt/var/lib/ucf 0 /mnt/var/lib/snmp 24K /mnt/var/lib/pam 128K /mnt/var/lib/systemd 2.6M /mnt/var/lib/samba 16K /mnt/var/lib/nfs 0 /mnt/var/lib/ftp 0 /mnt/var/lib/vim 8.0K /mnt/var/lib/replisync 12K /mnt/var/lib/connman 222M /mnt/var/lib/clamav 0 /mnt/var/lib/apache2 0 /mnt/var/lib/logrotate 8.6M /mnt/var/lib/readyNASVault 287M /mnt/var/lib My guess is that your issue is with clamav (the NAS antivirus service), but let's make sure of that.

jokeruk wrote: 2.7G /mnt/var/lib/plexmediaserver So not Antivirus, it's clearly Plex. 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. Where did your plex media server install come from? You should be using the x86 build from https://www.plex.tv/media-server-downloads/?cat=nas&plat=netgear#plex-media-server 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.

No. You could update to 6.10.9, but you'd need to install it manually from system->settings->update https://kb.netgear.com/000065653/ReadyNAS-OS-Software-Version-6-10-9 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.

Have you tried connecting both using the NAS hostname and its IP address? a different browser? using incognito mode? a different PC? rebooting the NAS from the front panel?

If you can use ssh, then see if it also works using admin as the user name.

  Once the problem occurs nothing will help until an o/s reinstall.
  after that I can log in as usual from any pc or ipad using factory log on details.
  
  we have a mix of o/s and browsers - just tried this morning with a windows xp machine (used for legacy software for vehicle programming)
  
  We’ve tried: Edge, Safari, Chrome, Firefox over windows xp, 10,11 - don’t have a win7 build at the mo although could spin up vm
