[PATCH] autofs 5.0.5 - add optional nss map read retries	none

Description Neal Kim 2011-04-20 21:45:31 UTC

Description of problem:

RFE Filed on behalf of Lars R. Damerow @ Pixar

We have cases where we need to tell large numbers of machines to reload their maps in a short time. All of these machines are configured to read maps from LDAP, and sudden avalanche of requests makes our LDAP servers bog down and run out of file descriptors. A good number of automount processes then can't connect to LDAP and shut down for a lack of map information.

We'd like automount to behave better in this regard. One approach that may work for us would be a configurable number of retry attempts along with a configurable delay between attempts. I've coded a proof-of-concept patch for this and have attached it here; it works well in my small-scale testing. It defaults to no retries, so admins that don't explicitly turn it on won't see any difference, but the others can have a little insurance against disappearing automounters.

Comment 2 Ian Kent 2011-04-21 00:26:39 UTC

Thanks for the patch.

I've had a quick look at it and although I can't say for
sure I think I'll need to make some changes, at least to
the master map red wait (using a patch I already have for
master map read wait).

Anyway, bottom line is, the change looks fine and I'll get
onto it as soon as I can.
