No write access to destination (Mac)

I have set all recordings to be made to their own library, on their own disk. It was working, but the disk filled up. So I replaced the 500GB HD with a 4 TB one.

First of all I quit Plex and cloned the new big one from the full smaller one. No errors and they seemed to contain exactly the same data. I disconnected the old one and ensured the new one had the exact same name as the smaller one had. So all stored paths would still work perfectly, but with more space to store new recordings.

That was yesterday, but today I see recordings failed with the above error. Since the permissions looked ok and anyway had been perfectly copied from the old disk, this was a puzzle. I messed about with chmod a bit to make sure permissions were perfect, but the recording that should be running still doesn’t start and shows the same problem.

I set up a new recording and it seemed to start, but now it has been ‘Aborted’. No doubt still thinks there’s no write access.

This is irritating beyond belief. It has all the write permissions it needs, but thinks otherwise and won’t record. Why on earth does Plex have this problem. It’s really simple. Are the file permissions ok to write? Yes, then bloody write. It worked before with the exact same permissions on the other HD, what is Plex getting wrong?

you have to delete and recreate the recordings. for some reason plex forgets where they’re supposed to go (even if in the UI it looks like it knows) In the logs it says “couldn’t get target root path for subscription” and tries to write to .grab instead of C:\blahblah\TV.grab or /media/tv/.grab etc

That may be true and indeed all new recordings are working. But the question is, why does Plex forget this? As far as Plex is concerned, nothing’s changed. It was working, turned off (Quit), then back on again and all paths are the same as before. So why does it forget and what prompted it to do so?
