Description of problem:
---------------------------------------
When trying to perform replace-brick operation from the rhevm-shell, using the following command, 

[RHEVM shell (connected)]# action brick bc0b1edc-2455-437a-991b-bfca4cb2b51a replace --cluster-identifier gluster --glustervolume-identifier vol1 --brick-server_id e54b7b16-92d2-4439-9312-74f1d435bd2f --brick-brick_dir /tmp/br1

the following error is seen - 

error: type "brick" does not exist.

Version-Release number of selected component (if applicable):
rhevm-cli-3.2.0.5-1.el6ev.noarch

How reproducible:
always

Steps to Reproduce:
1. Run command to replace a brick as described above.
  
Actual results:
The error says that the type 'brick' does not exist, which is not true.

Expected results:
The error message should give the correct error, if there is any error, otherwise the command should be executed.

AFAICS the error you see ain't related to the originally reported bug for cli,
please consider opening new one for api/engine instead.
Comment 3 Sahina Bose 2013-08-26 06:57:49 UTC 
Have posted patch to remove replace-brick, as this operation is planned to be removed from gluster as well.
Comment 6 Sahina Bose 2013-11-28 06:41:09 UTC 
Replace brick is marked deprecated.

Checked that the following command does not give a Null Pointer exception

action brick 9831a197-4efb-44a8-846a-2e7555d7aeaa replace --glustervolume-identifier 0b83bb0b-5a1a-4000-a489-1a95c044f683 --cluster-identifier Default --brick-server_id d3f5b6d8-fa84-4267-8dff-cd24bb119967 --brick-brick_dir /export/td3
Comment 7 SATHEESARAN 2014-01-06 06:59:58 UTC 
Tested with IS30 and glusterfs-3.4.0.53rhs-1

I hit NPE here in this context, when did tried to replace the brick as follows :

[RHEVM shell (connected)]# action brick e93eeec7-d2b6-49da-b340-6d8837901b04 replace --glustervolume-identifier b6e2ed30-370d-46b1-9071-fe851aa57caf --cluster-identifier 155234fe-976e-43af-ad30-7b760d7e7ca7 --brick-server_id fa1b1b2e-a433-4718-b3fd-13fcafa8fddd --brick-brick_dir /rhs/brick1/sbr1

I also see the following error snip from engine.log :

SETUP INFORMATION
==================
1. Created a GlusterFS Datacenter (3.3)
2. Created a gluster enabled cluster (by name gluster-cluster-1)
3. Added 2 RHSS Nodes to the cluster
4. Created a distribute-replicate volume of 2X2
5. Optimized the volume for virt-store
6. Started the volume
7. Tried to replace one of the brick, using rhevm-shell as follows :

[RHEVM shell (connected)]# action brick e93eeec7-d2b6-49da-b340-6d8837901b04 replace --glustervolume-identifier b6e2ed30-370d-46b1-9071-fe851aa57caf --cluster-identifier 155234fe-976e-43af-ad30-7b760d7e7ca7 --brick-server_id fa1b1b2e-a433-4718-b3fd-13fcafa8fddd --brick-brick_dir /rhs/brick1/sbr1


error: 
status: 400
reason: Bad Request

Got the error and engine.log pointed to NPE

Created attachment 845935 [details]
engine.log

engine.log  is attached and it contains the NULL POINTER EXCEPTION error, while doing replace brick from rhevm-shell
Comment 10 Juan Hernández 2014-02-25 15:16:49 UTC 
Sahina, is this still going to make 3.4? If not, please retarget.
Comment 12 Juan Hernández 2014-02-26 13:13:14 UTC 
I think that this can't be closed as WONTFIX, even if the replace-brick operation is deprecated. We need to either make it work (and that is what I prefer) or at least generate a clear error message for the user.

What is the impact for the user of not fixing this? Is the replace-brick operation something that users did frequently? Is there any alternative?
Comment 13 Sahina Bose 2014-02-27 05:06:01 UTC 
No, replace-brick is not done frequently. replace-brick is no longer supported in the underlying glusterfs. Users should do a remove-brick (with migrate) and add-brick instead.

We could change the REST API to return an error from the replace-brick call.
Comment 14 Juan Hernández 2014-02-27 10:11:02 UTC 
Yes, please modify the REST API so that it returns an error when the replace-brick call is performed. The error message should clearly indicate that the command isn't supported.

Also, open a new bug to remove the command completely in 4.0.
Comment 15 Juan Hernández 2014-02-27 10:44:09 UTC 
In the bug for 4.0, please add [DEPRECATION] as a prefix to the subject of the bug.
Comment 16 Juan Hernández 2014-03-25 14:45:16 UTC 
Sahina, it isn't clear to me if you finally modified the RESTAPI as suggested in comment 14. If you did, where is the patch?
Comment 17 Sahina Bose 2014-03-26 11:00:53 UTC 
Sorry - missed this...Yes..patch submitted as per comment 14. http://gerrit.ovirt.org/#/c/25259/
Comment 18 Sandro Bonazzola 2014-04-18 08:04:45 UTC 
All referenced patches have been merged, shouldn't this be in modified state?
Comment 19 SATHEESARAN 2014-05-20 12:01:09 UTC 
Verified with RHEV 3.4 [ av9.1] and RHS 3.0 nightly [ glusterfs-3.6.0.3-1.el6rhs ]
