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 the entries in an /etc/fstab file:

/dev/rz8a      /       ufs rw 1 1

/dev/rz8g / ufs rw 1 2
/dev/rz8b / ufs sw 1 2

To see the information on the /usr file system (which is mounted), enter the following command:

dumpfs /dev/rrz8g

The dumpfs command does not report information on the AdvFS file system.
