mddb.cf(4)
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)metadb command is invoked. You should never
directly edit this file.
The file /etc/lvm/mddb.cf is used by the metainit(1M) com-
mand 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 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 cor-
rupted. 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.
