Hi All,
I have to do disk mirroring, for that I have to create a metadb as disk mirroring have to do with SVM. However I do not have any slice free for metadb.
What are the options? Please suggest (4 Replies)
Hello All,
I have small doubt. It's related to SVM in solaris 10. I have created raid 0 (striping) using 3 slices of 500 MB size (default interlace value as 32KB)
d2: Concat/Stripe ---- Interlace value is 32 KB
Size: 2923830 blocks (1.4 GB)
Stripe 0: (interlace: 64 blocks)

mddb.cf(4) File Formats 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) 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 num-
bers 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 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.
