If you want the drives to be automounted and your automount system uses pmount to do the mounting (pmount allows mounting by a normal user without an entry in /etc/fstab) you may need to edit /etc/pmount.allow. If the drives are seen as non-removable, which SATA hard disks usually are, pmount will refuse to mount them unless you add the device name to /etc/pmount.allow, for example.
echo ‘/dev/sdb1’ >>/etc/pmount.allow
echo ‘/dev/sdc[123]’ >>/etc/pmount.allow
echo ‘/dev/sdd*’ >>/etc/pmount.allow
The first allows one particular partition to be mounted by pmount, the second example permits three specific partitions on a drive, while the third lets through every partition on a drive. Note the use of single quotes to stop the shell interpreting the wildcards.

Adding MySQL Cluster Data Nodes Online
The redistribution for NDBCLUSTER tables already existing before the new data nodes were added is not automatic, but can be accomplished using simple SQL statements in mysql or another MySQL client application. However, all data and indexes added to tables created after a new node group has been added are distributed automatically among all cluster data nodes, including those added as part of the new node group.

What Are Dynamic Disks and Volumes?: Storage Services
Dynamic disks were first introduced with Windows 2000 and provide features that basic disks do not, such as the ability to create volumes that span multiple disks spanned and striped volumes, and the ability to create fault tolerant volumes mirrored and RAID-5 volumes.
Dynamic disks offer greater flexibility for volume management because they use a database to track information about dynamic volumes on the disk and about other dynamic disks in the computer. Because each dynamic disk in a computer stores a replica of the dynamic disk database, Windows Server 2003 can repair a corrupted database on one dynamic disk by using the database on another dynamic disk.

I am unsure as to why this is done at the OS level.
