Description of problem: Vdsm overrides lvm configuration for vdsm lvm calls. We are using obtain_device_list_from_udev=0 which was a workaround for old udev bugs in EL 6. The udev issues should be fixed in Fedora 21 and EL 7. Test vdsm without obtain_device_list_from_udev=0 and remove this option if it works now. The advantage should be faster operation as lvm does not have to search /dev for block devices but get the devices from udev. See https://bugzilla.redhat.com/show_bug.cgi?id=1259587#c11
What's the priority of this bug? Do we want it for 3.6.0?
(In reply to Yaniv Kaul from comment #1) > What's the priority of this bug? Do we want it for 3.6.0? This is cleanup, using the platform as it was meant to be used, avoiding problematic .cache files (that were broken recently in 7.2). We want it in 3.6, but it is not urgent. Since the trivial patch is ready and tested, I don't see a reason to wait. ydary: this should be in next 3.6 release.
Strange, we have this bug twice - this is a duplicate of bug 1272027. I cannot explain how we have the same bug twice - maybe bugzilla failed but created the bug, and I submitted again? *** This bug has been marked as a duplicate of bug 1272027 ***
