TVheadend - CIFS mount timeshift buffer not deleting

Hi guys,

I'm running TVheadend server on my Pi and I've just noticed my NAS drive was running low on storage, then I saw that the timeshift buffer folder had grown to over 200GB, it seems that the buffer files are unable to delete themselves after writing to the mounted folder...

Can someone explain to me why the timeshift buffer folders do not delete after I stop a stream from a mounted CIFS share?

I've mounted my NAS livetv folder locally using the following

mount -t cifs -o username=guest,password=,rw,vers=1.0 //10.0.0.****** /storage/livetv

which works fine, however the buffer files created by timeshift are not deleting.... and if I try to delete these via ssh " rm -r /storage/livetv/timeshift/buffer" I get "permission denied" errors

Recordings are also recorded to the same CIFS share folder, but i'm able to delete them just fine.

Surely i'm missing something obvious here...

Can anyone confirm similar behaviour with mounted nas shares?

Seems weird that I can record to the same folder and delete said recording just fine... But the timeshift buffer will write, but not delete.

Writing the timeshift buffer locally or to a usb hdd works perfectly.
