Post subject: | Migrating recordings to a new machine |
Hi all, Not sure if this will help anyone, but i think i have solved my mythbackend segfault issue after upgrading from my old P4/mobo to a much more grunty AMD64 5200 dual processor and mobo. The story: I exported the recorded (and other tables) from the old R5.5 backend, and imported them into the fresh R5.5 backend. I noticed that i was getting frequent mythbacken segfault crashes when deleting recordings (after watching etc). The pattern seemed to form that if i deleted a recording from the old P4 box the segfault would occure, but not on new recordings. The solution (fingers crossed) The new machine has a new hostname (different to the old P4 box), so i think a simple msql sql update commend to update the hostname field in the recorded table to the new hostname has stopped the crashing/segfaults. The future Hopefully this has resolved the problem, i will post back if not. Cheers, Nathan |

The Mythtv wiki has instructions on changing host names here: http://www.mythtv.org/docs/mythtv-HOWTO-23.html#ss23.15 Last year when I migrated from R5F27 to R5.5 I used this command below in mysql to update the hostname: Code: UPDATE recorded SET hostname='newhost',starttime=starttime,endtime=endtime
WHERE hostname='oldhost'; I had a secondary backend / frontend that could not play recordings from the master because the migrated recordings had the old hostname. The command above fixed the issue. |

I've also posted a script which makes the substitutions in the DB for things like recordings and such. |
