Using the following lvm2 version on Ubuntu 16.04.3 running kernel 4.16.03 LVM version: 2.02.176(2) (2017-11-03) Library version: 1.02.145 (2017-11-03) Driver version: 4.37.0 ceph-volume attempts to create a VG on a raw block device to use as a bluestore OSD. The command it uses looks like this: vgcreate --force --yes ceph-a637b0e7-e54f-4fe9-8afc-a74671d94f6e /dev/sdi The disk (/dev/sdi) in this case is a blank (no partition table) GPT label 3.7T drive. vgcreate complains and fails: stderr: Device /dev/sdi excluded by a filter. I cannot figure out what "filter" is causing this. The global_filter in lvm.conf is wide open: filter = [ "a|.*/|" ] Turning up debug logging does not show any additional reasons. Repeatedly running pvscan or vgscan to update the cache does not fix it either. What could be blocking this device from being used? thanks, Wyllys Ingersoll Keeper Technology, LLC _______________________________________________ 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/
