Description Rahul C S 2012-02-29 03:48:27 EST
Description of problem:
There is no md-cache set option, I know stat-prefetch set does the same thing, but since stat-prefetch is not present now, we need to make a md-cache set/unset command.

gluster volume set md-cache on/off
Comment 2 Amar Tumballi 2012-12-21 00:48:14 EST
still a valid bug, but we need to keep backward compatibility, hence need to keep stat-prefetch, and add md-cache. Need to see how to achieve this.
Comment 3 Kaleb KEITHLEY 2015-10-22 11:40:20 EDT
pre-release version is ambiguous and about to be removed as a choice.

If you believe this is still a bug, please change the status back to NEW and choose the appropriate, applicable version for it.
Comment 4 Sachidananda Urs 2015-12-14 05:27:54 EST
This is still a bug. Since we always refer the feature as md-cache and not stat-prefetch ...

gluster vol set volname md-cache on/off 

Is the intuitive command.
Comment 5 Atin Mukherjee 2016-01-12 23:36:00 EST
This has been already fixed and md-cache option is available now.
Comment 6 Atin Mukherjee 2016-01-13 01:19:52 EST
I misread the code. md-cache option is still not introduced. Reopening the bug. Also assigning it to Raghavendra G as he is the maintainer of performance translators.
Comment 7 Atin Mukherjee 2016-01-13 01:23:43 EST
With the current infrastructure of managing op-versions, this would be difficult to fix considering the backward compatibility. Until and unless we have some design changes of managing the VME table this is not a easy fix. I'd consider not to fix this issue at this stage since GlusterD 2.0 is going to ease out in maintaining the op-versions & backward compatibility.
