Description Andrei Stepanov 2016-09-01 11:22:36 UTC

"Add brick" dialog has an option "Show available bricks from host", which doesn't work.

To add a brick it is necessary to deselect option "Show available bricks from host" and type a brick path manually. 

ovirt-engine-4.0.4-0.1.el7ev.noarch

1. Log in admin portal.
2. Have a GlusterFS cluster.
3. Have a host in a GlusterFS cluster.
4. Log in to the host and create any brick.
5. Select checkbox "Show available bricks from host" in "New Volume" -> "Add bricks"

List with a available bricks on the host stays empty.

Comment 1 Sahina Bose 2016-09-07 11:29:57 UTC

How were the bricks created on the host? Under which path was it mounted?

oVirt looks under /rhgs path for brick directories to list. (The path that it looks for is a configurable option)

Comment 2 Andrei Stepanov 2016-09-12 09:10:53 UTC

I created a new FS, and mounted it under : /rhgs/brick2

/dev/mapper/vg-gluster4 on /rhgs/brick2 type xfs (rw,relatime,seclabel,attr2,inode64,noquota)

option "Show available bricks from host" doesn't show this brick. I always need to create a gluster volume manually to be used in RHV.

Moreover, I do not have a configurable option to specify a path:

# engine-config -l | grep -i gluster
AllowClusterWithVirtGlusterEnabled: "Allows to create a Cluster with both Virt and Gluster services enabled" (Value Type: String)
GlusterRefreshRateHooks: "Refresh rate (in seconds) of gluster hooks from gluster servers" (Value Type: Integer)
GlusterRefreshRateGeoRepStatusInSecs: Refresh rate (in seconds) of the geo-replication session status and statistics (Value Type: Integer)
GlusterRefreshRateGeoRepDiscoveryInSecs: Refresh rate (in seconds) for discovery of geo-replication sessions (Value Type: Integer)

I think this part should be documented at:

https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/single/administration-guide/

Comment 3 Sahina Bose 2016-09-19 07:08:19 UTC

Ramesh, can you check?

Comment 4 Red Hat Bugzilla Rules Engine 2016-09-19 07:08:26 UTC

Bug tickets must have version flags set prior to targeting them to a release. Please ask maintainer to set the correct version flags and only then set the target milestone.

Comment 5 Ramesh N 2016-09-20 06:08:18 UTC

Default mount point for gluster bricks is  configurable using the vdc_option "GlusterDefaultBrickMountPoint". Default value for this option is '"/gluster-bricks" in upstream oVirt and /rhgs/' in RHEV-M. Make sure you have mounted the brick in correct path and same thing is shown under the 'Storage Devices' sub tab under 'Hosts'. 

Currently vdc_option "GlusterDefaultBrickMountPoint" is not exposed through 'engine-config' command. Let me expose this to engine_config and have it documented in the admin guide.

Comment 6 Sahina Bose 2016-12-22 08:43:31 UTC

Can you expose this option?

Comment 7 Ramesh N 2016-12-26 05:26:16 UTC

Yeap. I can expose this the option "GlusterDefaultBrickMountPoint"  to 'engine-config' command.

Comment 8 SATHEESARAN 2018-05-10 03:49:39 UTC

Tested with RHV 4.2.3 and gluster-3.12

vdc_option GlusterDefaultBrickMountPoint is exposed now and this makes the brick mounted under that listed

# engine-config -a | grep GlusterDefaultBrickMountPoint
GlusterDefaultBrickMountPoint: /rhgs version: general
