Description Eric Harney 2020-02-25 16:21:24 UTC

This bug was initially created as a copy of Bug #1741730


Description of problem:

glance_store needs work to support Cinder NFS volumes when using the Cinder backend for Glance.

Comment 1 Cyril Roelandt 2020-04-01 21:00:37 UTC

The first patch was merged.

A few questions:

1) Do we have to backport all three patches? The refactoring patch seems "optional" to me.

2) Can Mike test the fix just by setting the cinder_mount_point_base to a valid value, or are there other steps needed?

Thanks.

Comment 2 Rajat Dhasmana 2020-04-02 15:05:49 UTC

Hi Cyril,

There is one more patch i've added that will prevent nfs mount races per share. As for answers to your queries :

1) There are 3 patches, 709300,714391 and 716874 that needs to be backported to have the glance cinder store (with cinder nfs backend) work for OSP13.

2) To check all the changes, we could define cinder_mount_point_base value and create multiple images concurrently (given glance is using cinder store) and the expected output is : a) all volumes should be created in the folder '<cinder_mount_point_base>/nfs/<share hex uuid>' folder b) all images should be in active state

Thanks
Rajat Dhasmana

Unfortunately the bug can't be verified without bug 1741730 and bug 1843088, so this bug is being rescoped as "pass regression only" (which it did) with lower priority, and cloned for future verification together with the aforementioned bugs.
