Troubleshooting:Filesystem Permissions

Filesystem Permissions

A lot of problems people have with mythtv can be traced back to filesystem permission issues.

Subtle Issues

Unable to record, or watch live TV

You have set wide-open permissions but still can't write to a new disk you just installed:

$ ls -l /media/data/mythtv/
drwxrwxrwx 2 mythtv mythtv 4096 Jun 11 12:08 recordings

On Linux, and possibly other UNIXes, check the permissions of the underlying mount point:

$ grep mythtv /etc/fstab
/dev/sdb1 /media/data  ext4 defaults   0  2
$ sudo umount /media/data
$ ls -ld /media/data
drwxr-xr-x 1 root root 4096  Jun 10 11:08 /media/data

Also: check the permissions of each step in the path from /.
