Is it trustable today? The consensus is that LVM still isn't quite ready for prime time, and with big drives, no longer needed.

Thats done but with 2x the drive space now for amanda's vtapes, I have doubled the number of vtapes, and reconfigured it for that, and a starter session is running to shake it down & see if any bugs fall out. This is of course via the wrapper scripts I wrote years ago because the normal usage's recovery loses a days work. When my version is done, I can do a bare metal recovery to the state the system is in when the dump of that disklist entry was done, so a much smaller window for data loss doing it my way. The config that made that backup run, and the indices of everything than run did, is now appended to the vtape its making, after its been made. So the recovery, if I need to do it yet today, will be effectively a state about an hour into the future a/o right now. I takes at least and hour to run, but if gzip is heavily used, will be even longer, 3 hours & change a few times. Amanda schedules differently from other backup proggies, fiddling with its schedule to try and make each run consume about the same amount of tape on each run, but remaining within the limits of how long it can go between level 0's. Since this will be effectively the first run, I doubt it will be able to do a level-0 on the number of 35GB vtapes I gave it as the maximum it can use per run. The email I get will be "interesting". But amanda is a smart girl, so a week later, she'll be doing alright. Those scripts are available on my web pages if anyone else wants to play with them. The other 2T drive has been reconfigured for the next stretch install, but I'll not try another install until amanda is done, middle of the afternoon earliest estimate.
