dumpfs - Dump UFS file system information
/usr/sbin/dumpfs filesystem... | device
The dumpfs command prints out the super block and cylinder group informa-
tion 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 You must have the sysadmin command authorization to
run this command.
The dumpfs command does not report information on the AdvFS file system.
Specifies the command path.
Commands: fsck(8), newfs(8), tunefs(8)
