NAME
dumpfs - Dump UFS file system information
SYNOPSIS
/usr/sbin/dumpfs filesystem ... | device
DESCRIPTION
The dumpfs command prints out the super block and cylinder group information for the specified UFS file system(s) or special device. The
listing is very long and detailed. This command is useful for getting information about the file system block size and minimum free space
percentage, for example. If the file system is mounted, you must specify the raw device. The following is an example of device entries in
an /etc/fstab file: /dev/disk/dsk8a / ufs rw 1 1 /dev/disk/dsk8g / ufs rw 1 2 /dev/disk/dsk8b / ufs sw 1 2 To
see the information on the /usr file system (which is mounted), enter the following command:
dumpfs /dev/rdisk/dsk8g
The dumpfs command does not report information on the AdvFS file system.
