[ovirt-devel] Re: [VDSM] Running the new storage tests on your laptop

Hello Nir, Thanks for the sharing, it is very helpful! Are these test scripts open sourced and can be re-used by others for testing oVirt?

Thanks Jonkery On 2/14/2019 6:26 AM, Nir Soffer wrote: I want to share our new block storage tests, running on your laptop, from your editor, creating real block storage domain with real logical volumes. One catch, these tests require root - there is no way to create devices without root. To make it easy to run as root only the tests that need root, they are marked with "root" mark. Here an example of running the root tests for block storage domain: $ sudo ~/.local/bin/tox -e storage-py27 tests/storage/blocksd_test.py -- -m root And for lvm: $ sudo ~/.local/bin/tox -e storage-py27 tests/storage/lvm_test.py -- -m root To run all storage tests that require root: $ sudo ~/.local/bin/tox -e storage-py27 -- -m root tests/storage Another issue - after running the tests as root, you need to fix ownership of some files in .tox/, tests/htmlcov*, and /var/tmp/vdsm. You can: $ sudo chown -R $USER:$USER .tox tests /var/tmp/vdsm We will improve this later. Note that I'm running tox installed as user: $ pip install --user tox This gets most recent tox with minimal breakage of system python. With the new tests, our code coverage is now 57%: https://jenkins.ovirt.org/job/vdsm_standard-check-patch/2888/artifact/che... - blockSD: 47% https://jenkins.ovirt.org/job/vdsm_standard-check-patch/2888/artifact/che... - lvm: 74% https://jenkins.ovirt.org/job/vdsm_standard-check-patch/2888/artifact/che... These tests are rather slow, all the root tests take 26 seconds. But OST takes more then 40 minutes, and cover less code in this area. OST coverage for lvm mudle: 71% https://jenkins.ovirt.org/job/ovirt-system-tests_manual/4071/artifact/exp... To get debug the tests, you can use new option in recent pytest --log-cli-level: $ sudo ~/.local/bin/tox -e storage-py27 tests/storage/blocksd_test.py -- -m root --log-cli-level=info Here is an example output from a test creating a storage domain (use --log-cli-leve=debug if this is not verbose enough) ------------------------------------------------------------------------------- live log call ------------------------------------------------------------------------------- blockSD.py 1034 INFO sdUUID=d4d7649d-4849-4413-bdc2-b7b84f239092 domainName=loop-domain domClass=1 vgUUID=3OJX6U-UDLc-VFtg-2cRO-q3kR-UH2g-Nvf78I storageType=3 version=3, block_size=512, alignment=1048576 blockSD.py 600 INFO size 512 MB (metaratio 262144) lvm.py 1168 INFO Creating LV (vg=d4d7649d-4849-4413-bdc2-b7b84f239092, lv=metadata, size=512m, activate=True, contiguous=False, initialTags=(), device=None) lvm.py 1198 WARNING Could not change ownership of one or more volumes in vg (d4d7649d-4849-4413-bdc2-b7b84f239092) - metadata blockSD.py 522 INFO Create: SORT MAPPING: ['/dev/loop2'] lvm.py 1168 INFO Creating LV (vg=d4d7649d-4849-4413-bdc2-b7b84f239092, lv=inbox, size=16m, activate=True, contiguous=False, initialTags=(), device=None) lvm.py 1198 WARNING Could not change ownership of one or more volumes in vg (d4d7649d-4849-4413-bdc2-b7b84f239092) - inbox lvm.py 1168 INFO Creating LV (vg=d4d7649d-4849-4413-bdc2-b7b84f239092, lv=outbox, size=16m, activate=True, contiguous=False, initialTags=(), device=None) lvm.py 1198 WARNING Could not change ownership of one or more volumes in vg (d4d7649d-4849-4413-bdc2-b7b84f239092) - outbox lvm.py 1168 INFO Creating LV (vg=d4d7649d-4849-4413-bdc2-b7b84f239092, lv=ids, size=8m, activate=True, contiguous=False, initialTags=(), device=None) lvm.py 1198 WARNING Could not change ownership of one or more volumes in vg (d4d7649d-4849-4413-bdc2-b7b84f239092) - ids lvm.py 1168 INFO Creating LV (vg=d4d7649d-4849-4413-bdc2-b7b84f239092, lv=leases, size=2048m, activate=True, contiguous=False, initialTags=(), device=None) lvm.py 1198 WARNING Could not change ownership of one or more volumes in vg (d4d7649d-4849-4413-bdc2-b7b84f239092) - leases lvm.py 1168 INFO Creating LV (vg=d4d7649d-4849-4413-bdc2-b7b84f239092, lv=master, size=1024m, activate=True, contiguous=False, initialTags=(), device=None) lvm.py 1198 WARNING Could not change ownership of one or more volumes in vg (d4d7649d-4849-4413-bdc2-b7b84f239092) - master lvm.py 1333 INFO Deactivating lvs: vg=d4d7649d-4849-4413-bdc2-b7b84f239092 lvs=['master'] blockdev.py 84 INFO Zeroing device /dev/d4d7649d-4849-4413-bdc2-b7b84f239092/metadata (size=41943040) utils.py 454 INFO Zero device /dev/d4d7649d-4849-4413-bdc2-b7b84f239092/metadata: 0.00 seconds blockdev.py 84 INFO Zeroing device /dev/d4d7649d-4849-4413-bdc2-b7b84f239092/inbox (size=1024000) utils.py 454 INFO Zero device /dev/d4d7649d-4849-4413-bdc2-b7b84f239092/inbox: 0.02 seconds blockdev.py 84 INFO Zeroing device /dev/d4d7649d-4849-4413-bdc2-b7b84f239092/outbox (size=1024000) utils.py 454 INFO Zero device /dev/d4d7649d-4849-4413-bdc2-b7b84f239092/outbox: 0.02 seconds lvm.py 1438 INFO Changing VG tags (vg=d4d7649d-4849-4413-bdc2-b7b84f239092, delTags=[], addTags=['MDT_LEASETIMESEC=60', 'MDT_IOOPTIMEOUTSEC=10', 'MDT_LEASERETRIES=3', 'MDT_LOCKRENEWALINTERVALSEC=5', 'MDT_SDUUID=d4d7649d-4849-4413-bdc2-b7b84f239092', 'MDT_ROLE=Regular', 'MDT_POOL_UUID=', 'MDT_PV0=pv:loop2&44&uuid:wzupcF-uQME-3PIa-4WNf-THJJ-57MS-3UIdxD&44&pestart:0&44&pecount:157&44&mapoffset:0', 'MDT_CLASS=Data', 'MDT__SHA_CKSUM=ee58868dee52c4cc128f0ee89a0c382de1fe6419', 'MDT_LOGBLKSIZE=512', 'MDT_VGUUID=3OJX6U-UDLc-VFtg-2cRO-q3kR-UH2g-Nvf78I', 'MDT_PHYBLKSIZE=512', 'MDT_DESCRIPTION=loop-domain', 'MDT_TYPE=ISCSI', 'MDT_VERSION=3', 'MDT_LOCKPOLICY=']) lvm.py 1438 INFO Changing VG tags (vg=d4d7649d-4849-4413-bdc2-b7b84f239092, delTags=['RHAT_storage_domain_UNREADY'], addTags=['RHAT_storage_domain']) lvm.py 1325 INFO Activating lvs: vg=d4d7649d-4849-4413-bdc2-b7b84f239092 lvs=['master'] PASSED [ 50%] Nir _______________________________________________ Devel mailing list -- devel(a)ovirt.org To unsubscribe send an email to devel-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/devel@ovirt.org/message/BY67R2IBWKI...
