OS: ubuntu 14.04
lvm package: lvm2
I followed this procedure: https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/ (from the title: direct-lvm Configure fashion for production)
which lets you configure the LVM on a hard drive
I partition my drive sdb and then I followed step by step, I block out the following command:
lvconvert --zero n -y -c 512K --thinpool docker / thinpool --poolmetadata docker / thinpoolmeta
Here is the error message I: “Can not use thin logical volume docker / thinpool for thin pool data.”
Do you have an idea ?
