I am on Stoneburner for my main media system. Long story of why I cannot yet upgrade this one including need for TFTP server, iSCSI targets etc.
Anyway, this system has been going great and has been rock solid for quite a number of years. However, within the last few months the root filesystem has become 100% filled and I cannot seem be able to locate what is causing it.
I run Docker with three containers including MythTV and Emby and false media plugin. It has NFS exports also.
Anyway, as mentioned earlier, it has been running all this great for quite some time but it appears something (perhaps a package update) may have caused this.
If you can help suggest what I can try next, please let me know.
