NAME    [Toc]    [Back]

       dumpfs - Dump UFS file system information

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/dumpfs  filesystem... | device

DESCRIPTION    [Toc]    [Back]

       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 You must have the sysadmin command
       authorization to run this command.

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