NAME - metadevice state database replica locations


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

       The file /etc/lvm/ 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/ 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/  file	 are  of the form: driver_name
       minor_t daddr_t	checksum where driver_name and minor_t	represent  the
       device  number  of the physical device storing 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.

       Example 1 Sample File

       The following example shows a 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.
