Then create a file system on the previously defined logical volume: Once done, ensure that the volume group is varied off, for example for volume group fs01vg: Perform similar operations on node2. The filesystem is potentially mounted on another node After a system crash the filesystem may still have mount flags enabled and refuse to be mounted.
