Cover letter [bryder_autofs_4.1.4_PATCH 0/8] Patches to autofs 4.1.4 daemon to speed some things up and increase robustness
I'm releasing these patches for anyone still using the old autofs 4.1.4 daemon.
We still use autofs 4.1.4 where I work.
We have over 4,000 nfs clients using automounter (maps held in LDAP). We use simple indirect maps. In other words I've only tested LDAP with simple maps on nfs.
We have found many ways to make fileservers suffer from major performance problems.
Our preferred behaviour is for the automounter to keep trying to mount a location until the fileserver becomes less busy. Otherwise we have to deal with the fallout from EEXIST errors.
Along the way I've found other stuff which I've included (some of which only matters because the 4.1.4 daemon forks full processes rather than using threads).
I have included some other people's patches and have attributed them to the person I think did the patch in the first place. Apologies if I've got it wrong!
This published set is meant to clearly publish the work I've done - but include the bare minimum patches to autofs-4.1.4.tar.gz (from
http://www.kernel.org/pub/linux/daemons/autofs/v4/)
so that my stuff works and so it's clear what my patches do.
I've included CHANGELOG entries for each patch which hopefully explains what I've done for each patch.
However, I use a bunch more patches from the redhat rpms and some from kernel.org. A current picture of what I really use is available from
https://github.com/bryder/bryder_autofs414
So if you wanted to try this out - github is the place to get it from.
