Description surabhi 2015-10-27 06:44:44 UTC

Description of problem:

When we start a ctdb volume , the following entries gets added to smb.conf handled by hook script.(/var/lib/glusterd/hooks/1/start/post/S29CTDBsetup.sh)

clustering = Yes
idmap backend = tdb2

When we do testparm it gives error WARNING: The "idmap backend" option is deprecated 

The option should be like :
idmap config * : backend = tdb2


Version-Release number of selected component (if applicable):
glusterfs-3.7.1-16.el7rhgs.x86_64
samba-4.2.4-4.el7rhgs.x86_64

How reproducible:
Always

Steps to Reproduce:
1.Do ctdb setup
2.start the volume
3.execute testparm

Actual results:
Warning from testparm for idmap backend option which is deprecated now.

Expected results:
the id map backend option should be modified to idmap config * : backend = tdb2

This is not done always but only if 'clustering = yes' is not found
in the smb.conf file. The whole mechanism is fragile though and
conceptually wrong and should be removed completely. This is treated
in upstream bug #1290151. They have already been pushed to upstream
master.

My assessment is that this is currently irrelevant:
It is only cosmetic (a warning), and we should rather
proceed with bringing bug #1290151 to downstream.

My 2 cents.
