Yo All!
Newbie here. I have a number of data moving tasks now being handled
by rsync and rsnapshot, but those solutions are not able to scale to
my problems. Thus I am giving csync2 a shot.
I am runnning version 1.34 with two gentoo patches. Not sure what the
patches do. If anything I ask has been previously discussed here,
or elsewhere, then feel free to just point me to that.
Currently I am running a master with geographically dispersed slaves.
The slaves are runnning in daemon mode. The master is run from a
simple shell script:
while true; do csync2 -x; sleep 5m; done
I checked the doc, but I can see no description of what the master would
do if I run it in daemon mode. Does it just look at the hint table?
Does it loop continuously? Can I buy a clue?
Sometimes the net connection to the remote hiccups, and csync2 seems
to exit with a write error. Is there a retry mechanism, or do I just
need to keep re-running csync2?
I created the csync databases on master and slave this way:
csync2 -cIr /
Then jumped in to the above update loop. I am worried that some of
the files were not in sync before beginning, or may have been corrupted.
Is there a way to have csync2 do a scrubbing? Like the way an ECC
RAM controller slowly reads all RAM in the background to be sure all
the bits are working. I could see csync2 randomly testing X number of
files to be sure the master and slave checksums match.
Otherwise I may have to run an rsync every once in a while, but then I
am back to my problems with rsync being a bit flakey over the internet.
A doc typo at the start of the last paragraph of 3.4.5:
Usually the action is only triggered on the targed hosts,
I assume targed should be targeted.
And anything else a newbie should know about csync2?
TIA.
