Description Derrick Ornelas 2018-04-08 18:10:02 UTC

Description of problem:

The v4 REST API silently fails to update the read_only value for a disk attachment


Version-Release number of selected component (if applicable):
rhevm-4.1.10.3-0.1.el7
python-ovirt-engine-sdk4-4.1.7-1.el7ev


How reproducible: 100%


Steps to Reproduce:
1.  Edit VM's attached disk and check "Read-Only"

2.  Check read_only status to make sure it is "true"

  curl -u "user:pass" "https://rhvm.example.com/ovirt-engine/api/vms/<vm_guid>/diskattachments/<disk_id>"


3.  Update read_only and set to "false"

  curl -u "user:pass" -X PUT -H "Content-Type: application/xml" -d "<disk_attachment><read_only>false</read_only></disk_attachment>" "https://rhvm.example.com/ovirt-engine/api/vms/<vm_guid>/diskattachments/<disk_id>"



Actual results:

REST API returns HTTP 200 along with disk attachment XML, and read_only is still set to "true"


Expected results:

REST API returns HTTP 200 and read_only is set to "false"



Additional info:

Issue was first seen using python-ovirt-engine-sdk4.  We were testing v3 ovirt-engine-sdk-python script and found that /api/v3/vms/<vm_guid>/disks/<disk_id> does not return read_only value at all, so we switched to v4, then to simple curl test.  



Simple reproducer:

# cat test.sh 
#!/bin/bash -x

curl -u "admin@internal:mypass" "https://rhvm.example.com/ovirt-engine/api/vms/288662ee-e893-4e0a-be56-4a01af5c00ff/diskattachments/6ce0cc76-7be2-42c8-876b-769a5223e3e4"

echo -e "\n###\n"

curl -vvv -u "admin@internal:mypass" -X PUT -H "Content-Type: application/xml" -d "<disk_attachment><read_only>false</read_only></disk_attachment>" "https://rhvm.example.com/ovirt-engine/api/v4/vms/288662ee-e893-4e0a-be56-4a01af5c00ff/diskattachments/6ce0cc76-7be2-42c8-876b-769a5223e3e4"

Comment 1 Derrick Ornelas 2018-04-08 18:23:54 UTC

I've also tested this with the v3 API, and, although /api/v3/vms/<vm_guid>/disks/<disk_id> does not return the read_only value at all, it does get updated properly


# cat testv3.sh 
#!/bin/bash -x

curl -v -u "admin@internal:mypass" "https://rhvm.example.com/ovirt-engine/api/v3/vms/288662ee-e893-4e0a-be56-4a01af5c00ff/disks/6ce0cc76-7be2-42c8-876b-769a5223e3e4"

echo -e "\n###\n"

curl -vvv -u "admin@internal:mypass" -X PUT -H "Content-Type: application/xml" -d "<disk><read_only>false</read_only></disk>" "https://rhvm.example.com/ovirt-engine/api/v3/vms/288662ee-e893-4e0a-be56-4a01af5c00ff/disks/6ce0cc76-7be2-42c8-876b-769a5223e3e4"

echo -e "\n###\n"

curl -v -u "admin@internal:mypass" "https://rhvm.example.com/ovirt-engine/api/v3/vms/288662ee-e893-4e0a-be56-4a01af5c00ff/disks/6ce0cc76-7be2-42c8-876b-769a5223e3e4"



# /usr/share/ovirt-engine/dbscripts/engine-psql.sh -c "select is_readonly from vm_device where device_id = '6ce0cc76-7be2-42c8-876b-769a5223e3e4'"
