Could it be because you initiated the pvcreate command way too early and the DRBD resource was still in use? ________________________________ From: drbd-user-bounces at lists.linbit.com [mailto:drbd-user-bounces at lists.linbit.com] On Behalf Of Robinson, Eric Sent: Sunday, October 12, 2008 8:39 AM To: drbd-user at lists.linbit.com Subject: [DRBD-user] LVM+DRBD+LVM On two Centos 5.2 (2.6.18-92.1.10.el5) servers, I did the following: created logical partition /dev/sda5 created PV, volume group VG01, and logical volume LV01 created drbd resource with the following options: device /dev/drbd0; disk /dev/vg01/lv01; This worked fine. Server 1 is now primary, server 2 is secondary, both are up to date. When trying to prepare my DRBD resource for use as a PV, I issued the command: pvcreate /dev/drbd0 And got: Failed to write physical volume "/dev/drbd0" I ran: parted -l And got: Number Start End Size Type File system Flags 1 32.3kB 83.9GB 83.9GB primary ext3 2 83.9GB 92.5GB 8587MB primary linux-swap 3 92.5GB 92.6GB 123MB primary ext3 boot 4 92.6GB 1198GB 1105GB extended lba 5 92.6GB 1198GB 1105GB logical Error: Unable to open /dev/md0 - unrecognised disk label. I ran fdisk, looked at the partition tables, and quit without saving changes. Then I tried parted again and got: Number Start End Size Type File system Flags 1 32.3kB 83.9GB 83.9GB primary ext3 2 83.9GB 92.5GB 8587MB primary linux-swap 3 92.5GB 92.6GB 123MB primary ext3 boot 4 92.6GB 1198GB 1105GB extended lba 5 92.6GB 1198GB 1105GB logical Error: Unable to open /dev/drbd0 - unrecognised disk label. Error: Unable to open /dev/md0 - unrecognised disk label. NOTE: Now there's two unrocognized disk labels, one of which is drbd0. So then I tried the command again: pvcreate /dev/drbd0 And got: Physical volume "/dev/drbd0" successfully created What the heck? -- Eric Robinson Director of Information Technology Physician Select Management, LLC 775.885.2211 x 111 Disclaimer - October 12, 2008 This email and any files transmitted with it are confidential and intended solely for drbd-user at lists.linbit.com.
