Mogilefs configuration meanings

[Zubin]

Hey guys, I've setup Mogilefs successfully but I've used most of the
default parameters.

The version of Mogilefs i set up is 2.20

I was looking through various howto's and noticed a lot of
configuration parameters that I don't have in my configs and I was
wondering if someone can give me a quick explanation of the following
configuration parameters and if they are still valid for 2.20.



/etc/mogilefs/mogilefs.conf

listener_jobs 5
delete_jobs = 1
replicate_jobs = 5
reaper_jobs = 1
monitor_jobs = 1
fsck_jobs = 1
daemonize = 1
mog_root = /mnt/mogilefs



etc/mogstored/mogstored.conf

maxconns = 10000



/etc/mogilefs/mogtool.conf

overwrite = 1
chunksize = 32M
receipt = ad...@bigmaps.com
verify = 1
concurrent = 3


A quick explanation of each of these parameters would be greatly
appreciated, particularly the mogilefs.conf ones

Thanks,

Zubin Parihar

These control the number of the various workers running... leave the last
3 at one, and tune the rest upward if necessary. ie; if deletes are
lagging, add more delete workers. if your requests aren't being processed
very fast, you might need more listeners (queryworkers).

whether or not to background mogilefsd.

meh.

Useless unless you're using mogtool to store very large backups of
files... easy enough to just ignore this.

These really aren't documented in the mailing list history or wiki

Uhhhm. Embarassing. We should be moving to the google pages wiki. Anyone
want to finish moving pbwiki over there so we can retire it?
