release open_disk error
by Frido Roose 08 May '12

08 May '12

Hello, I wonder what the "open error -1" / "release open_disk error" messages in sanlock.log actually mean. I saw these messages in the log on a KVM host that rebooted, and after running "/usr/sbin/virt-sanlock-cleanup" on that host. The resources where disks from 2 guests running on another KVM host. So in fact the disks are still in use, bot got cleaned up by the other KVM host because it thought they were not longer in use... Several questions: 1. Could this indicate a problem with the lease of these resources on the server that host these guests? 2. Is there a way to reregister these resources, because they are still in use (but not for sanlock it seems)? 3. Overall, is it a bad idea to run virt-sanlock-cleanup? Some entries from the log file: 538 s1:r35 resource __LIBVIRT__DISKS__:e133401bfdff6979f76d9544ec8a5529:/var/lib/libvirt/sanlock/e133401bfdff6979f76d9544ec8a5529:0 for 1,9,4218 539 open error -1 /var/lib/libvirt/sanlock/e133401bfdff6979f76d9544ec8a5529 539 r35 release open_disk error /var/lib/libvirt/sanlock/e133401bfdff6979f76d9544ec8a5529 598 s1:r40 resource __LIBVIRT__DISKS__:fc82f9999b5afddb8aee9955db9b3477:/var/lib/libvirt/sanlock/fc82f9999b5afddb8aee9955db9b3477:0 for 2,12,4230 598 open error -1 /var/lib/libvirt/sanlock/fc82f9999b5afddb8aee9955db9b3477 598 r40 release open_disk error /var/lib/libvirt/sanlock/fc82f9999b5afddb8aee9955db9b3477 598 s1:r42 resource __LIBVIRT__DISKS__:ff9b82672a4dd869f9c9b38a6cbe3900:/var/lib/libvirt/sanlock/ff9b82672a4dd869f9c9b38a6cbe3900:0 for 2,12,4232 598 open error -1 /var/lib/libvirt/sanlock/ff9b82672a4dd869f9c9b38a6cbe3900 598 r42 release open_disk error /var/lib/libvirt/sanlock/ff9b82672a4dd869f9c9b38a6cbe3900 -- Frido Roose

[Patch] Libvirt - Fix locking for readonly devices
by David Weber 08 May '12

08 May '12

Hi, I'm currently working on getting sanlock into Debian/Ubuntu. While testing, I noticed that I wasn't able to add a readonly or shared device: "internal error unsupported configuration: Readonly leases are not supported". After looking into the source, it seems to be the following situation: - Libvirt passes every device to the sanlock plugin, even if it is readonly - The sanlock plugin rejects to add a lease for the readonly device, returning an error so the machine starts to fail The attached patch rejects passing readonly and shared devices to the lock-plugin so they shouldn't be a problem anymore. Would this be an appropriated way to fix this problem? (I'm neither experienced in libvirt nor C) What seems odd to me is that Fedora either doesn't hit this or nobody has ever reported it. I'm not member of this list so please CC me. Thanks! Cheers, David
