clri(1M)

NAME
     clri - clear inode

SYNOPSIS
     clri [ -F samfs ] [ -V ] mount-point i-number

AVAILABILITY
     SUNWsamtp

DESCRIPTION
     clri writes zeroes on the inode numbered i-number on the Sun
     QFS or SAM-QFS file system currently mounted on mount-point.
     i-number can be expressed as either a  decimal  integer,  an
     octal integer prefixed with a zero, or a hexidecimal integer
     prefixed with 0x.

     clri must be run as  root.   Once  you've  cleared  all  the
     inodes you wish for a filesystem, you'll need to unmount and
     remount the filesystem to flush the  inode  cache  to  disk.
     Finally,  if  there are any directory entries which point at
     the newly-cleared inodes, those directory  entries  will  be
     cleared  automatically  by the filesytem the first time they
     are referenced.

EXAMPLE
     Here's an example of using clri:

          Mount the filesystem

     bilbo# mount /sam1

          Find out the inode number which must be cleared.  Here, let's say
          we would like to clear "file0."

     bilbo# cd /sam1/test
     bilbo# sls -i
        169 file0     166 file3     339 file5      60 file7     160 file9
        342 file2      63 file4     163 file6     336 file8

           Ok, now we have its inode: 169.  Let's clear it!

     bilbo# /opt/SUNWsamfs/tools/clri /sam1 169

           But, look!  It's still there!  Sure looks weird, though...

     bilbo# sls -l file0
     ----------   0 root     root             0 Dec 31  1969 file0

           Even "sync" doesn't help...

     bilbo# sync
     bilbo# sls -l file0

     ----------   0 root     root             0 Dec 31  1969 file0

           ...until we unmount and remount the filesystem.

     bilbo# cd /
     bilbo# umount /sam1
     bilbo# mount /sam1
     bilbo# cd /sam1/test

           This is actually what clears the directory entry:

     bilbo# ls -l file0
     file0: No such file or directory

           And, now it's gone!

     bilbo# ls -l
     bilbo 64
