Description Anush Shetty 2015-11-03 12:31:11 UTC

Description of problem: The volume info currently lists n-1 servers as backupvolfile-servers. The backupvolfile-server mount option expects only one value, and not a comma-separated set of values.


Version-Release number of selected component (if applicable): heketi-devel-1.0.0-1.el7rhgs.noarch


How reproducible: Always


Steps to Reproduce:
1. Create a heketi volume
2. The output of a volume creation command successfully executed has the mount options value
3.

Actual results:

Mount Options: backupvolfile-servers=rhshdp03.lab.eng.blr.redhat.com,rhshdp04.lab.eng.blr.redhat.com,rhshdp06.lab.eng.blr.redhat.com,rhshdp13.lab.eng.blr.redhat.com

When I try to mount it, I get the following error:

mount -t glusterfs -o backupvolfile-server=rhshdp03.lab.eng.blr.redhat.com,rhshdp04.lab.eng.blr.redhat.com,rhshdp06.lab.eng.blr.redhat.com,rhshdp13.lab.eng.blr.redhat.com rhshdp05.lab.eng.blr.redhat.com:vol_20363034cdd3439f675d6db92da6bb3b /mnt/

Invalid option rhshdp04.lab.eng.blr.redhat.com

Anush, Since this is an interface to services and not to users, Heketi provides services with all possible choices for backupvolfile-servers. It is up to the service to show the user the correct service choice.

Does that make sense?

It does, though it would be useful to just pull it off as is to run a mount command. Also, the output format is similar to the mount option syntax. So it could be confusing unless we clearly mention it?

Updated the API spec file.

Marking this as verified.
