[Gluster-users] snapshot mount fails in 3.12

[Amar Tumballi]

Hi Richard,

Thanks for posting this.

This issues is caused as part of the regression in 3.12.0 version [1], and
is already fixed in 3.12.3 [2] version (3.12.3 is tagged now with couple of
more subdirectory mount related fixes).

[1] - https://bugzilla.redhat.com/show_bug.cgi?id=1501235
[2] - https://review.gluster.org/#/c/18506/

If you don't want to change the versions, then please remove the check for
'subdir-mount' in '/sbin/mount.glusterfs' and it will all work fine.

Regards,
Amar
