Mark,
You are correct. The issue was with that piece of code. A patch has
been posted to fix it - http://gerrit.ovirt.org/#/c/13155/

for GLUSTER DOMAIN case
Deepak,
I suspect it's related to the following code snippet.
// storage_pool can be null when discovering iscsi send targets
or when connecting
// through vds which has no storage pool
if (storage_pool == null || Config.<Boolean>
GetValue(ConfigValues.AdvancedNFSOptionsEnabled,
storage_pool.getcompatibility_version().getValue())) {
// For mnt_options, vfs_type, and protocol_version - if
they are null
// or empty we should not send a key with an empty value
...
con.putIfNotEmpty("vfs_type", connection.getVfsType());
...
}
If my understanding is correct, AdvancedNFSOptionsEnabled is true only
for DC 3.1 and 3.2. What's your DC version?
It should be 3.2, otherwise it could not be compatible with glusterfs
domain. Anyway, you could add some debugging code
to see if the 'vfsType' options is added to parameters. You also could
use wireshark confirm if it's sent by ovirt-engine.
Of course, you need disable SSL at first before capturing packets.
Don't blame me if it doesn't help at all. :-)
Mark.
