[mythtv-users] Missing Disk Space with XFS

[Poobah]

Brian (and Glen),
	After posting this, I found an earlier discussion of this issue
("Deleting Recordings does not release Disk Space" 10-13 thru 10-15)
that describes this issue as the frontend not having direct access to
the file structure thru NFS and being able to delete the file.  Isaac
mentions that those that have the issue "can simply use CVS."  Since I'm
not keen on running CVS code, I guess I'll work around it until 0.17.

	0.14 and 0.15 were pretty unstable on my box, and I had to write
a watchdog script that would restart mythbackend if it borked.  I think
the hard drive space issue is a side effect of 0.16 being so stable ;-)


Thanx!

Mark

To both Mark and Glenn,

This is probably a software bug of not closing files.  I saw it
on my machine a while back.  Keep in mind on Unix/Linux,
you can "unlink/delete" a file that is open by a process.
The file will be removed from the directory listings, but the
file will still be there and taking up space until all processes
close that file (if any have it open).

Therefore, you probably just have to exit and restart
the mythtv front and backend programs to reclaim your
space, not reboot or unmount the partition.
