Hi everyone, I'm running into an issue where I'm using nfs on my multi-node setup for /var/lib/nova/instances so that I can use live migration. Things work great unless I try to spawn multiple vm instances simultaneously and the image does not yet exist in the _base directory. I will get multiple spawning errors on a few of the instances that are trying to spawn, usually with the following error: OSError: [Errno 2] No such file or directory: '/var/lib/nova/instances/_base/1cab2bf14012771017e66501a98bf594877c9d2d.part'. It looks like multiple nodes are trying to do things on the same file and 1 node is deleting the file while the others are trying to access it thus producing this error. Once the image and the resized image based on flavor is out there and present in the _base directory then I no longer get errors when spawning multiple instances at the same time. So basically it seems to be an issue only the first time an image has to be copied over from glance and resized. Anyone seen this or is this a known issue when running multi-node instance directory over nfs and/or glusterfs?
