@rhtyd I checked this one with him. The problem happens on Qemu 2.10+ (running on Ubuntu). The release notes from Qemu have the following message. ``` Qemu 2.10 added the requirement of a --force-share flag to qemu-img info when reading information about a disk that is in use by a guest. We do this a lot in Nova for operations like gathering information before live migration. ``` The problem is happening when ACS tries to get some info from a volume using qemu-img. Then, one would get the following error. ``` qemu-img: Could not open '/mnt/.../../volumeID': Failed to get shared "write" lock Is another process using the image? ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
