I was unable to reproduce this with the steps shown in comment #32 (with two changes as below). The used kernel was 3.2.0-27.43-generic running as a VM. I tried both the VG on a partition and the VG on a loop-mounted backing file.
To make the testcase work, the snapshot lvcreate needed "--snapshot <vg>/<lv>" and the dd command used was "dd if=/dev/zero of=/dev/<vg>/<lv> bs=1M oflag=direct". This would end with an IO error as soon as the snapshot exception store was full. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1023755 Title: Precise kernel locks up while dd to /dev/mapper files > 1Gb (was: Unable to delete volume) To manage notifications about this bug go to: https://bugs.launchpad.net/cinder/+bug/1023755/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
