Public bug reported: Binary package hint: lvm2
LVM cannot create a snapshot of a LUKS encrypted volume. To reproduce: 1. Install Ubuntu 10.04 Lucid Lynx to a LUKS root using the alternate installer. 2. Run: lvcreate --snapshot /dev/vg00/root --size 2G --name backup --verbose This hangs the system. Verbose lvcreate messages are normal. The last line printed is: Suspending vg00-root (252:1) with filesystem sync with device flush The console error is: [360:540149] INFO: task flush-252:1:486 blocked for more than 120 seconds. [360:609736] INFO: task lvcreate:1320 blocked for more than 120 seconds. These console messages periodically repeat, but lvcreate never returns and the system becomes unresponsive and requires a hard reset. The snapshot volume is created and is visible after boot, but it seems to be corrupt: # mount /dev/vg00/backup /mnt mount: unknown filesystem type 'DM_snapshot_cow' ** Affects: lvm2 (Ubuntu) Importance: Undecided Status: New ** Tags: crash cryptsetup hang luks lvcreate lvm snapshot -- creating a LUKS snapshot hangs the system https://bugs.launchpad.net/bugs/615911 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
