Overview
Procedure
Provision an unformatted block device. For this example, it will be referred to as /dev/sdb.
Verify your configuration. You should have a dm.thinpooldev value in the /etc/sysconfig/docker-storage file and a docker-pool logical volume:
# cat /etc/sysconfig/docker-storage DOCKER_STORAGE_OPTIONS=--storage-opt dm.fs=xfs --storage-opt dm.thinpooldev=/dev/mapper/docker--vg-docker--pool # lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert docker-pool rhel twi-a-t--- 9.29g 0.00 0.12
Before using Docker or OpenShift Container Platform, verify that the docker-pool logical volume is large enough to meet your needs. The docker-pool volume should be 60% of the available volume group and will grow to fill the volume group via LVM monitoring.
