Hi all,
The subdir export is one of key features for NFS server. NFS-ganesha
have already supports subdir export,
but it has lot of limitations when it is intregrated with gluster.
Current Implementation :
Following steps are required for a subdir export
* export volume using ganesha.enable option
* edit the export configuration file by adding subdir options
* do refresh-config in that node using ganesha-ha.sh
* limitation : multiple directories cannot be exported at a time via
script.
If user to need to do that(it is possible), all the
steps should be done in manually
which includes creating export conf file, use latest
export id, include it in ganesha conf etc.
And also here it become mandatory to export root
before exporting subdir.
Suggested approach :
* Introduce new volume set command "ganesha.subdir" which will handle
above mentioned issue cleanly
for example, gluster volume set <volname> ganesha.subdir
<path1,path2,path3 ...>
if u want to unexport path2, use the same command with mentioning path2
gluster volume set <volname> ganesha.subdir <path1,path3 ...>.(Is
different option required ?)
The root of the volume should be export only using ganesha.enable
options.
This require a lot of additions in glusterd code base and minor
changes in snapshot functionality.
Can above mentioned improvement targeted for 3.7.x release (3.7.10 or
3.7.11) or should I need to move it for 3.8 release ?
Please provide your valuable feedback on the same.
Please Note : It is not related to subdir export for fuse mount.
Regards,
Jiffin
