NAME
       mddb.cf - metadevice state database replica locations

SYNOPSIS
       /etc/lvm/mddb.cf

DESCRIPTION
       The  /etc/lvm/mddb.cf  file  is created when the metadb(1M) command is invoked. You should
       never directly edit this file.

       The file /etc/lvm/mddb.cf is used by the metainit(1M) command to find the locations of the
       metadevice  state  databases  replicas. The metadb command creates the file and updates it
       each time it is run. Similar information is entered in the /kernel/drv/md.conf file.

       Each metadevice state database replica has a unique entry in  the  /etc/lvm/mddb.cf  file.
       Each  entry  contains the driver and minor unit numbers associated with the block physical
       device where a replica is stored. Each entry also contains the block number of the  master
       block, which contains a list of all other blocks in the replica.

       Entries	in the /etc/lvm/mddb.cf file are of the form: driver_name minor_t daddr_t  check-
       sum where driver_name and minor_t represent the device number of the physical device stor-
       ing  this replica. daddr_t is the disk block address. checksum is used to make certain the
       entry has not been corrupted. A pound sign (#) introduces a comment.

EXAMPLES
       Example 1 Sample File

       The following example shows a mddb.cf file.

	 #metadevice database location file do not hand edit
	 #driver minor_t daddr_t device id	 checksum
	 sd	 152	 16	 id1,sd@SSEAGATE_JDD288110MC9LH/a	 -2613

       In the example above, the value for daddr_t indicates that the offset from the start of	a
       given partition is 16 disk blocks from the start of that partition.
