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

17 The file /etc/lvm/mddb.cf is used by the metainit(1M) command to find
18 the locations of the metadevice state databases replicas. The metadb
19 command creates the file and updates it each time it is run. Similar
20 information is entered in the /kernel/drv/md.conf file.
21
22
23 Each metadevice state database replica has a unique entry in the
24 /etc/lvm/mddb.cf file. Each entry contains the driver and minor unit
25 numbers associated with the block physical device where a replica is
26 stored. Each entry also contains the block number of the master block,
27 which contains a list of all other blocks in the replica.
28
29
30 Entries in the /etc/lvm/mddb.cf file are of the form: driver_name
31 minor_t daddr_t checksum where driver_name and minor_t represent the
32 device number of the physical device storing this replica. daddr_t is
33 the disk block address. checksum is used to make certain the entry has
34 not been corrupted. A pound sign (#) introduces a comment.

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