[Networker] Balancing use of multiple adv_file disk devices
2007-07-30 05:05:40
We're running nw_7_3_2_jumbo.Build.11 on Solaris 10.
If I create two 750GB adv_file disk device volumes and put them into the
same pool, is there a way to tell networker to distribute savesets
equally between these two volumes? At present, the first volume is 80%
used (as reported by "df -k"), while the second is less than 1% full. I
know I could have created a 1500GB volume instead of two smaller 750GB
volumes, but that solution doesn't scale as well.
The "Target Sessions" parameter is set to "4" on both devices; however,
the usage pattern is such that there will rarely be more than 4 savesets
being written at a time. I could reduce the target sessions for the
first device until the second one is equally full, but that's an awkward
way to control usage over time.
If an "even distribution policy" isn't possible, can I instead configure
a "spillover policy", where it stops writing to the first volume once it
reaches a certain usage level?
I took a look at the staging policy, and there are lots of knobs I can
tweak, but I don't think that there's anything that will let me achieve
the desired effect.
Cheers,
Paul
