Specifically, OpenStack Cinder requires reliability here. [Test Case] The following test case seems to trigger the bug on two classes of hardware I've used, but not on a virtual machine: sudo apt-get install lvm2 # A free block device BDEV="sdb" # Create original LVM volume. pvcreate /dev/$BDEV vgcreate testing-vg /dev/$BDEV lvcreate -L 1024M -n testing test # Run a snapshot create/delete cycle and observe frequent failures. lvcreate -L 1024M --name testing-snapshot --snapshot /dev/testing-vg/testing lvremove -f /dev/testing-vg/testing-snapshot Example failure: $ lvcreate -L 1024M --name testing-snapshot --snapshot /dev/testing-vg/testing $ lvremove -f /dev/testing-vg/testing-snapshot Logical volume "testing-snapshot" created Unable to deactivate open testing--vg-testing-real (252:2) Failed to resume testing. [Solution] Recent updates in Debian+Saucy to the LVM and dm udev rules seem to alleviate the issue and I no longer see it when applying those changes from lvm2 2.02.98-6ubuntu1 (Patch attached) ------- # lsb_release -a Distributor ID: Ubuntu Description: Ubuntu Saucy Salamander (development branch) Release: 13.10 Codename: saucy # uname -r 3.11.0-4-generic # dpkg -l | grep lvm2 ii lvm2 2.02.98-1ubuntu5 amd64 Linux Logical Volume Manager Experiencing this on saucy across a number of boxes, all of similar hardware.
