Fixed In Version:		Doc Type:	Known Issue
Doc Text:	.The Calamari API sometimes incorrectly prints standard output as an error When using the Calamari `/cli` endpoint, the Calamari API response swaps the standard output (`stdout`) and standard error (`stderr`). As a consequence, the `err` field contains information from the `stdout` field. This behavior does not have any impact on the Calamari API commands.	Story Points:	---

4 days to implement

Comment 3 Christina Meno 2016-04-11 23:42:58 UTC

http://hostname:8002/api/v2/cluster/<fsid>/cli

POST
{
    "command": ["ceph", "osd", "pool", "mksnap", "rbd", "rbd_snapshot", "--format=json-pretty"]
}

Comment 4 Harish NV Rao 2016-06-10 12:13:17 UTC

I am able to create the pool snapshots using the cli api but once api completes successfully it prints as follows:
{
    "out": "", 
    "err": "created pool ecpool_test3 snap ecpool_test3_snapshot_2\n", 
    "status": 0
}

Note here that "created pool ecpool_test3 snap ecpool_test3_snapshot_2\n" is a message indicating successful creation of pool but is printed as "err". This message should have been printed against "out". 

Looks like this is happening for all the create commands that print success message.

Tested on:
calamari-server-1.4.0-0.12.rc15.el7cp.x86_64
ceph version 10.2.1-13.el7cp

Comment 6 Christina Meno 2016-06-14 16:38:29 UTC

I'll fix it in 2.1

Comment 11 Christina Meno 2016-06-20 18:00:27 UTC

This is wrong and to generic "When using the `create` command in the Calamari REST-based API to create for example pools or pool snapshots,"

I recommend saying specifically, "When using the /cli endpoint Calamari API response swaps stdout and stderr, e.g. the err field actually contains stdout"

Comment 14 Christina Meno 2016-07-13 16:07:16 UTC

Looks fine

Comment 16 Andrew Schoen 2016-10-05 14:44:47 UTC

This ticket was reopened for an error that was different than the original bug. I've opened a new ticket to track this new bug.
