I get this (the master backend is hal, the slave is ernie):
root at hal:~# df -k /home
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/vg1-lv1 459100320 360828500 93607624 80% /home
root at ernie:~# df -k /home
Filesystem 1K-blocks Used Available Use% Mounted on
nfs:/home 459100320 360828480 93607648 80% /home
This is with the system idle so those numbers are stable. The total size is
the same but, strangely, the used/free numbers are out. They're consistently
out by 20k/24k. Could this be due to different block sizes? If so how do I
set the blocksize on an NFS mount?
Would this also explain why I'm seeing occasional playback pauses? The
frontend is on the slave and most of the recordings are made on the master.
Mplayer on the frontend has no problems with playback over NFS, so I'm just
speculating that the frontend may be using the Myth protocol to play
recordings rather than NFS.
Cheers,
Tim.
