[Gluster-devel] mount_dir value seems clobbered in all /var/lib/glusterd/vols/<vol-name>/bricks/<node-name>:<brick-path> files

[Avra Sengupta]

Hi Milind,

Are the bricks lvm mounterd bricks. This field is populated for lvm 
mounted bricks, and used by them. For regular bricks, which don't have a 
mount point this valus is ignored.

Avra
