I followed the various guides to create a LVM
thin pool storage volume using the helper script
container-storage-setup. Here is the result: ------------------------ # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sr0 11:0 1 492K 0 rom vda 252:0 0 20G 0 disk ├─vda1 252:1 0 1G 0 part /boot └─vda2 252:2 0 19G 0 part └─atomicos-root 253:0 0 19G 0 lvm /sysroot vdb 252:16 0 100G 0 disk ├─dockervg-docker--pool_tmeta 253:1 0 104M 0 lvm │ └─dockervg-docker--pool 253:3 0 99.8G 0 lvm └─dockervg-docker--pool_tdata 253:2 0 99.8G 0 lvm └─dockervg-docker--pool 253:3 0 99.8G 0 lvm --------------------------------- with this configuration file: --------------------------------- # cat /etc/sysconfig/docker-storage-setup VG=dockervg GROWPART=enable AUTO_EXTEND_POOL=enable MIN_DATA_SIZE=8G POOL_AUTOEXTEND_THRESHOLD=60 POOL_AUTOEXTEND_PERCENT=10 -------------------------------------- and this setup: --------------------- # cat /etc/sysconfig/docker-storage DOCKER_STORAGE_OPTIONS="--storage-driver devicemapper --storage-opt dm.fs=xfs --storage-opt dm.thinpooldev=/dev/mapper/dockervg-docker--pool --storage-opt dm.use_deferred_removal=true --storage-opt dm.use_deferred_deletion=true " ----------------------- Now I would like to extend the atomicos VG with adding the /dev/vdb physical volume, but I have an error: --------------------------- # pvs PV VG Fmt Attr PSize PFree /dev/vda2 atomicos lvm2 a-- <19.00g 0 /dev/vdb dockervg lvm2 a-- <100.00g 0 # vgextend atomicos /dev/vdb Can't open /dev/vdb exclusively. Mounted filesystem? ------------------ What am I doing wrong? How do you guys extend the atomic root with the storage volume? Thank you. |
