Solaris volume Manager ( SVM )

Main components in SVM are :

1. meta database (Replpicas)

       Its the database contains each and everything about meta devices or volumes (d0,d1,..).

2. Meta device or volumes

       These are created on the different physical slices of different hard disks.
        And meta devices also created by using already existing meta devices.

Advantages:

  1. Create the file systems across the disks.
  2. Grow the file system online  (with out downtime)
  3. Providing the redundancy using RAID concepts

 Practical :
   Creating the meta database :
    #metadb -f -a -c 2 c0t2d0s0 c0t2d0s1 c1t0d0s0

   To show meta database source locations :

    #metadb

   To see the all meta devices :

    #metastat

   Creating the meta device with RAID 0 concatination

   #metainit -f 2 1 c0t2d0s0 1 c0t2d0s1
 
   Creating the meta device with RAID 0 striping :

   #metainit -f 1 2 c0t2d0s0  c0t2d0s1
