Linux: added a new disk/dev/SDB, but there is no partition, direct mount the/a directory, there is now a logical volume of space is not enough, want to/dev/SDB, cent gives a partition/dev/sdb1, added to the logical volume; I am to tell/dev/sdb1 to create physical volumes times wrong: Can 't open/dev/sdb1 exclusively. Mounted filesystem
The first is to uninstall the original mount/dev/SDB? After unloading the data/a what is the effect?
