Description of problem: Created a bootable volume from an image and booted an instance. I could create and delete one snapshot. The subsequent snapshots failed with error. Tested on RHEL 6.5 Version-Release number of selected component (if applicable): glusterfs-fuse-3.4.0.57rhs-1.el6_4.x86_64 fuse-libs-2.8.3-4.el6.x86_64 fuse-2.8.3-4.el6.x86_64 openstack-cinder-2013.2-9.el6ost.noarch How reproducible: Always Steps to Reproduce: 1. Create a volume from image: # cinder create --image-id fbc1d618-f43d-44cd-833b-e5e9d30f8605 10 2. Once the volume becomes available, boot an instance using the volume. # nova boot --flavor 2 --boot-volume 17339cd6-0464-4dc2-872c-d7d46184fc5f test 3. Create a snapshot of the attached volume. # cinder snapshot-create --force True --display-name test 17339cd6-0464-4dc2-872c-d7d46184fc5f +---------------------+--------------------------------------+ | Property | Value | +---------------------+--------------------------------------+ | created_at | 2014-01-22T08:48:23.559706 | | display_description | None | | display_name | test | | id | ba05d4a8-d527-41b8-be4e-5dd33b06ac8e | | metadata | {} | | size | 10 | | status | creating | | volume_id | 17339cd6-0464-4dc2-872c-d7d46184fc5f | +---------------------+--------------------------------------+ # cinder list +--------------------------------------+-----------+--------------+------+-------------+----------+--------------------------------------+ | ID | Status | Display Name | Size | Volume Type | Bootable | Attached to | +--------------------------------------+-----------+--------------+------+-------------+----------+--------------------------------------+ | 17339cd6-0464-4dc2-872c-d7d46184fc5f | in-use | None | 10 | None | true | c4ca46df-aed6-45b7-a380-c23f07842df2 | # cinder snapshot-list +--------------------------------------+--------------------------------------+-----------+--------------+------+ | ID | Volume ID | Status | Display Name | Size | +--------------------------------------+--------------------------------------+-----------+--------------+------+ | ba05d4a8-d527-41b8-be4e-5dd33b06ac8e | 17339cd6-0464-4dc2-872c-d7d46184fc5f | available | test | 10 | +--------------------------------------+--------------------------------------+-----------+--------------+------+ 4. Delete this snapshot: # cinder snapshot-delete ba05d4a8-d527-41b8-be4e-5dd33b06ac8e # cinder snapshot-list The snapshot is not listed anymore. 5. Create another snapshot of the same volume: # cinder snapshot-create --force True --display-name test 17339cd6-0464-4dc2-872c-d7d46184fc5f Actual results: The second snapshot creation fails with error: # cinder snapshot-list +--------------------------------------+--------------------------------------+--------+--------------+------+ | ID | Volume ID | Status | Display Name | Size | +--------------------------------------+--------------------------------------+--------+--------------+------+ | 9b243e79-4a51-4832-8c2d-f33ed3ad8f8e | 17339cd6-0464-4dc2-872c-d7d46184fc5f | error | test | 10 | +--------------------------------------+--------------------------------------+--------+--------------+------+ I see that the first snapshot still exists in the nova/mnt # ll /var/lib/nova/mnt/4db90e5492997091a102ba6ad764dade total 17885 -rw-rw-rw-. 1 qemu qemu 10737418240 Jan 22 14:05 volume-17339cd6-0464-4dc2-872c-d7d46184fc5f -rw-r--r--. 1 qemu qemu 197120 Jan 22 14:06 volume-17339cd6-0464-4dc2-872c-d7d46184fc5f.ba05d4a8-d527-41b8-be4e-5dd33b06ac8e -rw-r--r--. 1 cinder cinder 223 Jan 22 14:06 volume-17339cd6-0464-4dc2-872c-d7d46184fc5f.info Expected results: Should be able to create subsequent snapshots.
