Installation guide

/usr/sbin/fsck [ options ...][file_system ...]
If you do not specify a file system, all the file systems in the /etc/fstab
file are checked. If you specify a file system, you should always use the raw
device.
Refer to the fsck
(8) reference page for information about command options.
See Section 7.10 for information about how this command interacts with
overlapping partitions.
_______________________ Note _______________________
To check the root file system, you must be in single-user mode,
and the file system must be mounted read only. To shut down
the system to single-user mode, use the shutdown command.
AdvFS uses write-ahead logging instead of the fsck utility. As your system
mounts, AdvFS checks all records in the recovery log for system
inconsistencies and makes corrections as needed. Refer to AdvFS
Administration for more information.
7.4 Accessing File Systems
You attach a file system to the file system tree by using the mount
command, which makes the file system available for use. The mount
command attaches the file system to an existing directory (mount point).
_______________________ Note _______________________
The Tru64 UNIX operating system does not support 4-KB
block-size file systems. The default block size for Tru64 UNIX
file systems is 8 KB. To access the data on a disk that has 4-KB
block-size file systems, you must back up the disk to either a
tape or a disk that has 8-KB block-size file systems.
When you boot the system, file systems that are defined in the /etc/fstab
file are mounted. The /etc/fstab file contains entries that specify the
device and partition where the file system is located, the mount point, and
additional information about the file system, such as file system type. If
you are in single-user mode, the root file system is mounted read only.
