Hi list,
The following wiki page provides detailed information on "Volume
life cycle extensions"
or more fondly referred to as Hooks. Hooks are scripts/executables
that would
be run on the trigger of events like volume-start, volume-stop, etc.
This allows admin
to customise her volume 'deployment' work-flow. Of course it is not
arbitrarily expressive/powerful
yet.

This (conceptually) is similar to hooks provided by oVirt/VDSM. I
have a naive Q tho'
How to enable/disable a hook for a particular volume ? Is it that if
i don't set any key=value for a particular volume, the hook won't
come into action. In other words hooks will use key=value to
determine what they need to do ?
Scripts whose name begin with 'S' are enabled and anything else would
be disabled
I have updated the wiki with the answer to your question. Thanks for
asking!
(See
http://www.gluster.org/community/documentation/index.php/Features/Hooks#Detailed_Description)
Hmm, still not clear. Let me reword my Q.
Scripts that are enabled are not tied to a particular volume, rite ?
Assuming that, if a script is enabled, then it would run/invoke for all
volumes. How do i control the running of a script at the volume level ?
Say i need to run a script for all volume except one.. how do i control
that ?
