Hello, When trying to remove a dm-snapshot device, I see lvremove freezing. A reboot is then needed to get the system in a usable state again. I know that previous freezes/segfaults on removing a snapshot have been traced to a problem with kcopyd, but I am running linux 2.6.16.16 which should contain the fix for these problems. So it seems that my problem is different. The freeze happens consistently, and even if the snapshot and/or real device have not been accessed. For example, I type: # lvcreate --size 1G --snapshot --name homesnap vg0/home # lvremove vg0/home Are you sure ... ? Y [ lvremove now frozen ] If a filesystem was mounted on the original vg0/home, any attempt to access the filesystem will freeze as well. Other than that, the system remains responsive. After a reboot, I see that vg0/home and vg0/homesnap are both still present but set to inactive. I can then lvremove vg0/homesnap and lvchange vg0/home to reactivate it. If I strace lvremove on its one-way trip, I see that it sends a few DM_SUSPEND ioctls, then freezes on a DM_TABLE_LOAD ioctl. Am I doing something wrong with the snapshot, or is this still a bug? I seem to remember that I had it working correctly some time ago, but now it fails all the time. My system is Debian 3.1, linux 2.6.16.16, lvm2 2.01.04. Thanks, Joris. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
