ReadyNAS RR4312 - /dev/md0 partition full
Hi guys, I cannot have access to a ReadyNAS WEBGUI. After entering the user's credentials I get "ReadyNAS Admin Page is offline". But I'm able to access it via ssh session and I noticed that "/d...

Going a little bit deeper I found that "gencache.tdb" file in "/var/cache/samba" directory is the one occuping most of the disk space.
How big is it? On my own NAS it is about 650 KiB.

You should be able to delete the file, but you might need to stop Samba first.
Just removing the file is a very bad idea, if it will even let you. The following should work:
systemctl stop samba net cache flush systemctl start samba
However, that won't prevent it from filling up again, and I'm not familiar enough with it to know what kinds of things can fill it, though I do read that it apparently has no automatic trimming capability.
Is this in a Windows Domain environment, possibly with a lot of users? One of my guesses is that could cause an issue.
If it is a Windows Domain environment with a lot of users you may find ReadyNAS OS 6: "Do not cache ADS accounts locally" option useful
This is a good point mdgm has. This might be what is causing the cache to be so large.

Samba was "dead". The "systemctl status samba" returned:
Failed to dump process list, ignoring: Unit samba.service not found.
● samba.service
Loaded: not-found (Reason: No such file or directory)
Active: inactive (dead)The "net cache flush" is running for almost 40 minutes and nothing changed (no space reduction)
Any addtional suggestions?

Try
systemctl stop smb
But I think you will also have to delete the tdb file (or move it to the data volume) after you flush the cache.
Hi,
Its size is around 1,6 GB.
At this point, I don't want to delete the file. I'd prefer another workaround like clean the file ou reduce its size.
