Greetings all, on stock ubuntu natty, using liblvm 2.02.66, sometimes lvm_vg_create_lv_linear () gets stuck in the following stack. #0 0x00007f3b9636a0f7 in semop () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007f3b9606863c in dm_udev_wait () from /lib/libdevmapper.so.1.02.1 #2 0x00007f3b973df41b in ??

In my application, I have a udev monitor for "block" subsystem type, but currently it does nothing with the events it receives (it calls udev_monitor_receive_device(), udev_device_get_action() and then udev_device_unref() for every event. I plan in the future to use it for waking up other threads. Can somebody pls advise on how to investigate this issue. It does not happen always. Thanks, Alex. _______________________________________________ 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/
