LVM.EXE

LVM.EXE is the new version of the FDISK command. It provides both logical and physical views of the hardfiles installed on the system. With LVM (Logical Volume Manager), users can:

• Create Compatibility Volumes (partitions) which can be seen by pre-LVM releases of OS/2
• Create or delete Logical Volumes which span physical disks
• Extend file systems (JFS only)
• Delete Compatibility Volumes (partitions)
• Recover read or write failures from a portion of the disk going bad (JFS only)

NOTE

OS/2 needs for booting a HPFS or a FAT (better not) partition it can't boot from JFS.

NOTE

JFS is also available for Linux. To create an OS/2 compatible partition use the -O parameter.

Format 3rd partition on 2nd hard disk with the volume label "JFS_hdb3" and OS/2 compatibility:

mkfs.jfs -L -O JFS_hdb3 /dev/hdb3

Parameter for mkfs.jfs:

• -c Check the device for bad blocks before building the file system.
• -j journal_device Set the journal device. (Experimental)
• -L volume_label Set the volume label for the file system.
• -O Provide case-insensitive support for compatibility with OS/2.
• -q Quiet execution - do not ask for confirmation before creating the file system.
• -s log_size Set the log size (in megabytes). If the -s option is not used, the default is 0.4% of the aggregate size.
• -V Print version information and exit (regardless of any other chosen options).
