Storage preparation for an LVM shared storage

According to the Installing and configuring DRBD section in Chapter 4, Configuring a Proxmox VE Cluster, we have built an LVM volume with the /dev/sdc1 partition on both the Proxmox nodes to form our DRBD device. The /dev/sdc1 partition contains an LVM identifier on it as the LVM storage, and the LVM service tries to import it to the system; this might affect our DRBD mount point. It would be better to filter out this device to prevent any possible error by editing the /etc/lvm/lvm.conf file on both cluster nodes. Before we make any change to the file, we should back up the file with the following command:

root@vmsrv01# cp /etc/lvm/lvm.conf /etc/lvm/lvm.conf.bak

Then, we can make the following changes:

Original: filter = ["a/.*/" ]
New: filter = ["a|/dev/drbd1|", "r|/dev/sdc1|", "a/.*/" ]

In this example, we have defined the configuration, which is explained in the following points:

  • a|/dev/drbd1|: This accepts LVM scanning on /dev/drbd1

  • r|/dev...
