[mythtv-users] slave backend recordings missing

[Richard Woelk]

Good morning,

Since today's update of mythtv 0.27.1 I am unable to play any of my slave backend 
recordings on all frontends, even on the slave backend machine. The recordings are dark in 
my theme, and popup a warning "Recording Unavailable"
This setup was running fine until today's update.

First a little about my setup. Two machines, Combined Frontend/Master Backend named "thor" 
at 192.168.2.1 and a slave backend named "charlie" at 192.168.2.3 Both run Ubuntu 14.04 
with mythbuntu updates. the version is shown as 
2:0.27.2+fixes.20140701.572c4e3-0ubuntu0mythbuntu3

thor has one ATSC capture card getting over the air, with two disks mounted at /disk1 and 
/disk4
the storage groups are at /disk1/video and /disk4/video. charlie has two HDPVR-1212s 
connected to two satellite receivers, and two storage groups at /disk2/video and /disk3/video

The frontend will show the following error 100x, run from either machine

PlaybackBoxHelper: CHECK_AVAILABILITY 'myth://192.168.2.3/charlie' file not found

I have had 0 byte files where the same error shows up 
myth://192.168.2.3/1279_20140701180000.mpg instead

the slave backend will show a similar error in the logs

same in the backend logs, and still in this version, a real 0 byte file (or missing file) 
will show the proper filename.

It looks to me like instead of the filename, the server hostname is being inserted.
New scheduled recordings are not playable. LiveTV works, and if I hit record from inside 
live TV that show is playable.
but as soon as I restart the backend, everything is offline again.

I have dropped my database and started clean, on all 3 version that I have tried

About two weeks ago, I tried the 0.27/candidates repository and had the same issues. After 
a day I reverted back, using my database backup. The same issue exists for me in 
0.28.0~master.20140630.c70ae26 from mythbuntu repos.

Another curious effect. If I change my configuration so that thor is the slave, and 
charlie is the master. The unavailable recordings flip, and this issue follows the backend 
that is started as a slave.

I have tried to search, but since it shows my hostnames, I can't search for the exact 
string. I couldn't find anyone else in dev or users mailing list with the same issue.

Thanks for your help,
