Are you sure the file is sync’ed to disk? From: 谭 明宵 [mailto:tanmingxiao at outlook.com] Sent: Tuesday, March 6, 2018 5:54 PM To: openstack <openstack at lists.openstack.org> Subject: [Openstack] Some questions about "Cinder Multi-Attach" in Openstack Queens I installed the openstack queens use devstack. I want to test the "Cinder Multi-Attach" function 1. create a multiattach volume ``` # cinder type-create multiattach # cinder type-key multiattach set multiattach="<is> True" # cinder create 10 --name multiattach-volume --volume-type <volume_type_uuid> ``` 2. attache the volume to two instances ``` # nova volume-attach test01 <volume_uuid> # nova volume-attach test02 <volume_uuid> ``` 3. mount the volume , create some file，but the file don't sync between the two instance，It seems that they are two independent volumes then test02 create a file，but i cannot find it in test01,The reverse is the same. I think i have something wrong，the test like the "share storage" What should the correct effect be like? thanks -------------- next part -------------- An HTML attachment was scrubbed...
