Description Nir Soffer 2013-10-29 12:39:54 EDT
Description of problem:

In lvm-2.02.100-7 lvm stops using udev cache for getting the device list. This may cause performance issue when using lot of logical volumes.

After installing this version of lvm, obtain_device_list_from_udev option should be set to 0 in /etc/lvm/lvm.conf. This setting is a workaround for concurrency issues in udev cache.

See bug 1014942 and bug 1020401 for more details.
