Description Flags
replica selection during new pool creation none

Description Avi Liani 2021-02-08 11:24:55 UTC 
Description of problem (please be detailed as possible and provide log
snippests):

while trying to create new RDB pool (for compression) from the UI,
in the replica selection list, you can select replica-2 or replica-3, while the cluster was created with replica-4 (default for arbiter)

Version of all relevant components (if applicable):

OCP:    4.7.0-0.nightly-2021-02-06-084550
OCS:    ocs-operator.v4.7.0-254.ci

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?

yes, creation of new pool for compressed data is impossible

Is there any workaround available to the best of your knowledge?

no

Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?

1

Can this issue reproducible?

yes


Can this issue reproduce from the UI?

yes

If this is a regression, please provide more details to justify this:


Steps to Reproduce:
1. deploy OCP 4.7
2. deploy OCS 4.7 with Arbiter
3. create new SC with new Pool


Actual results:

in the replica section you can select replica-2 / replica-3

Expected results:

the list will contain replica-4

IMO, the fix should be that users  are not given any option to select replica values other than 4, rather than adding replica-4 to the list.

i.e. either a)disable replica 2 and 3 and add 4 or
b)  disable the whole replica field for arbiter and set default replica count for every pool as 4. (IMP more preferred). We can even mention the reason why the replica drop down is disabled 

WDYT ?

I think that option b) is the preferred one.

testing this on 

OCP : 4.7.0-rc.3
OSC: 4.7.0-268.ci
Ceph: 14.2.11-123.el8cp

and i see the same - when trying to create new compressed pool, i can select for replica : Replica-2 / Replica-3
and not Replica-4
Comment 8 Ankush Behl 2021-02-24 06:51:58 UTC 
The fix is available in the 4.8(check target release) nightly builds of OCP and till this bug is verified in 4.8 we can't backport to 4.7. So we need to test with 4.8 builds.

Moving this to ON_QA again.
Comment 9 Avi Liani 2021-02-24 08:13:21 UTC 
Tested and verified on :

Platform : AWS - i3
OCP      : 4.8.0-0.nightly-2021-02-24-021848
OCS      : ocs-operator.v4.7.0-268.ci
LSO      : local-storage-operator.4.7.0-202102110027.p0 

now it is working as expected and when i am trying to create new pool, in the replica selection i can see only replica-4.

screenshot is attached.
