Description Primary striping level, allowing a single virtual file system to be constructed of multiple physical disks Primary mirroring level, where all data written to a virtual file system is copied in real time to a separate mirroring disk A secondary mirroring level, which uses Hamming codes for error correction A secondary striping level, which writes parity information to a single drive, but writes all other data to multiple drives A secondary striping level, which writes parity information to a single drive, but writes all other data to multiple drives A striping and mirroring level, which allows data to be written to different disks, including parity information

is also copied in real time to a separate physical disk that has the same capacity as the original. This level has the slowest performance for writes, because all data must be written twice to two different disks; it also costs the most, because each drive to be mirrored uses a second drive that cannot be used for any other purpose. However, full redundancy can be achieved using RAID Level 1, and read performance is very good. The remaining RAID levels are variations on these two themes. RAID Level 2 is a secondary mirroring level that uses Hamming codes for error correction. RAID Levels 3 and 4 are secondary striping levels, writing parity information to a single drive, but writing all other data to multiple physical disks. In contrast, RAID Level 5 is a striping and mirroring level that allows data, including parity information, to be written to different disks. RAID 5 offers the best solution for systems that require both mirroring and striping. The RAID levels are summarized in Table 16-1.

The following procedure can be used to mount a local file system:
# mkdir /export/home # mount /dev/dsk/c0t3d0s5 /export/home # cd /export/home # mkdir pwatters # ls pwatters # cd /; umount /export/home
16:
File System and Volume Management
# mkdir /usr/local # mount /dev/dsk/c0t3d0s5 /usr/local # cd /usr/local # ls pwatters
The mkdir command is used to create mount points, which are equivalent to directories. If you wish to make a mount point one level below an existing directory, you can use the mkdir command with no options. However, if you want to make a mount point several directory levels below an existing directory, you need to pass the option p to the mkdir command. For example, the following command creates the mount point /staff, since the parent / directory already exists:
# mkdir /staff
However, to create the mount point /staff/nfs/pwatters, you would use the p option if the directory /staff/nfs did not already exist:
# mkdir -p /staff/nfs/pwatters
Once a mount point has been created, you use the mount command to attach the file system to the mount point. For example, to mount the file system /dev/dsk/c0t3d0s5 on the mount point /export/home, you would use the following command:
# mount /dev/dsk/c0t3d0s5 /export/home
The mount command assumes that a UFS file system will be mounted. If the target file system is non-UFS, you need to pass an option specifying the file system type on the command line by using the F options. Supported file system types include the following: nfs Network File System (NFS) pcfs MS-DOS formatted file system s5fs System V compliant file system Details of all currently mounted files are kept in the /etc/mnttab file. This file should never be directly edited by the superuser. The /etc/mnttab file will contain entries similar to the following:
# cat /etc/mnttab /dev/dsk/c0t0d0s0 / ufs rw,intr,largefiles,suid,dev=1100000 921334412 /proc /proc proc dev=2280000 922234443 fd /dev/fd fd rw,suid,dev=2240000 922234448 mnttab /etc/mnttab mntfs dev=2340000 922234442 swap /tmp tmpfs dev=1 922234451 /dev/dsk/c0t0d0s5 /usr ufs rw,intr,onerror=panic,suid,dev=1100005 922234441
Part IV:
Managing Devices
Configuring /etc/vfstab
If you want a disk to be available after reboot, you must create an entry in the virtual file systems table (/etc/vfstab). An entry like this,
/dev/dsk/c0t3d0s5 /dev/rdsk/c0t3d0s5 /export/home ufs 2 yes -
contains details of the slice s block and raw devices, the mount point, the file system type, instructions for fsck, logging, and a flag to force mount at boot. These options are largely equivalent to those used with the mount command. All file systems, including floppy disks, can be listed in the virtual file systems table. The mount point configuration for the floppy drive is typically similar to the following:
fd /dev/fd fd no -
Instead of mounting file systems individually by using the mount command, you can mount all file systems defined in /etc/vfstab by using the mountall command:
