7.3.1 Creating a File System on an LVM or RAID Virtual Device

To create a file system on an LVM volume, use the following steps:

1. Create a loop disk label. This is a fake disk label, that tells Parted to treat the virtual device as a single file system. With this fake disk label, there is either zero or one partition.

   (parted) mklabel loop
   

2. Create the file system, by using Parted's mkpartfs command. You should make the start of the file system 0. The partition can end anywhere inside the virtual device. You can find out the size of the virtual device with the print command. For example:

   (parted) print
   Disk geometry for /dev/md0: 0.000-47.065 megabytes
   Disk label type: loop
   Minor    Start       End     Filesystem  Flags
   (parted) mkpartfs primary ext2 0 47.065
   (parted) print
   Disk geometry for /dev/md0: 0.000-47.065 megabytes
   Disk label type: loop
   Minor    Start       End     Filesystem  Flags
   1          0.000     47.065  ext2
