| sabhain | Is it better to upgrade a backend server, or do a complete re-install? Currently on 10-10 or 10-04. | 20:57 |
| sabhain | Some version of LTS I think | 20:57 |
| sabhain | Generally things are stable, but I'm getting longer and longer freezes at the top and bottom of the hour | 20:58 |
| sabhain | Also, I need to add a slave backend to the system, and that's a new system | 20:58 |
| superm1 | sabhain: if it's LTS it's 10.04 probably then | 21:01 |
| superm1 | depends on how your data is organized for which i would say is better | 21:02 |
| superm1 | if you are putting recordings on a separate partition/drive, it's probably easier to just backup your mythconverg database, reinstall, reload database | 21:02 |
| superm1 | if recordings are on same drive, you just need to be careful that they don't get lost in the reinstall | 21:03 |
| sabhain | superm1: they're on separate drives, but within the same system. | 21:03 |
| superm1 | ok. the other question is what other stuff have you done different than the standard install? | 21:03 |
| superm1 | if you installed a lot of apps or configured a lot of services specially, that's just extra work to redo later so an upgrade might be more convenient | 21:04 |
| sabhain | I think it's pretty vanilla, really, outside of customizing LIRC settings. The big thing I'm going to lose in the upgrade will be diskless | 21:04 |
| sabhain | I've been running diskless on 3 front-ends .. and it's been pretty awesome. But with the cost of a small SSD what it is, I'm prepared to just do separate installs again. | 21:04 |
| superm1 | yeah it's too bad we don't have a good way to do diskless anymore | 21:05 |
| superm1 | i wish it would be revived | 21:05 |
| sabhain | It's really been the most stable server I've ever had. | 21:05 |
| superm1 | if you're getting freezes, i'd be wary to think it's actually the software though | 21:05 |
| superm1 | like the HW is frozen? | 21:06 |
| sabhain | I'd love to jump in and figure it out .. but just too much happening. I understand from another user (wyhzzrd??) that it works, it's just the ltsp arguments that need to be tweaked | 21:06 |
| superm1 | or like a long mysql query is pegging the system? | 21:06 |
| sabhain | whenever you're watching anything (live, recorded, or video) .. and the system is recording and switches programs (at the top or bottom of the hour generally), I get a 5-10 second *hesitation* .. and then playback resumes as if norma. | 21:07 |
| sabhain | normal | 21:07 |
| sabhain | hardly ever get any real hangs or freezes that require a restart | 21:07 |
| sabhain | maybe 3-4 times a year? | 21:08 |
| superm1 | ohh | 21:11 |
| superm1 | yeah that's mysql queries | 21:11 |
| superm1 | i've read posts on mailing list about people with major problems on that | 21:11 |
| sabhain | I was wondering if there was some sort of log that I should clear out | 21:11 |
| superm1 | it's lessened with newer versions of mythtv, but some other stuff you can do: | 21:11 |
| superm1 | 1) optimize the mysql database | 21:11 |
| superm1 | 2) move mysql to a different drive | 21:12 |
| superm1 | check and see which mysql optimizations you have enabled | 21:13 |
| superm1 | http://www.mythtv.org/wiki/Optimizing_Performance | 21:13 |
| superm1 | there's more on there | 21:13 |
| superm1 | http://code.mythtv.org/trac/ticket/2335 also fixes a problem like that, but it's from versions that came out before ubuntu 10.04 | 21:17 |
| sabhain | superm1: how do you do (2)? You relocate the database from / ? | 21:21 |
| Jay2k1 | stop mysql, move the directory somewhere else, then symlink the directory back | 21:22 |
| sabhain | and would there be a performance improvement if the recordings themselves were on a different system than the backend processes? Say a JBOD on the LAN? | 21:23 |
| sabhain | or a streamlined NFS server? | 21:23 |
| superm1 | sabhain: well the key is database on a separate drive from recordings | 21:29 |
| superm1 | not sure your mounting structure though, are they on the same drive? | 21:29 |
| superm1 | i don't think putting recordings on a JBOD on a LAN would help, you'll just saturate your LAN link and make your frontend performance dip | 21:30 |
| sabhain | superm1: what's the default location of mysql? | 21:39 |
| superm1 | sabhain: /var/lib/mysql i thinks | 21:40 |
| sabhain | they're on different physical drives. the mythconverg is on the / drive with the system files, but all recordings are on different drives | 21:41 |
| superm1 | yeah then that shouldn't change things for you | 21:58 |
| superm1 | try those mysql database optimizations | 21:59 |
| possum007 | What does "Error opening jump program file" mean? | 23:52 |
