Description Amar Tumballi 2010-10-15 05:37:23 EDT

We need a gluster command itself to collect state dump, instead of current way of issuing SIGUSR1 on a process id. This is more handy.

Comment 1 Amar Tumballi 2011-04-25 05:33:48 EDT

Please update the status of this bug as its been more than 6months since its filed (bug id < 2000)

Please resolve it with proper resolution if its not valid anymore. If its still valid and not critical, move it to 'enhancement' severity.

Comment 2 Amar Tumballi 2011-08-22 03:33:45 EDT

Please work on this.

Shishir had sent a patch to handle this: http://patches.gluster.com/patch/7039/ but this may not be enough.

What we should have from this feature.

* Enable an CLI option for setting 'statedump' path for given volume. (and the individual brick dump will have brick-path in its log file name, so it should be uniq per volume).

* Enable a CLI command to take the statedump on all the brick processes which are running at the moment (per volume).

* Enhance the above command of taking statedump to consider only few parts of state-dumps. (inode/memory/priv/stack etc).

Let me know if you have any questions on this.
