       extendfs - Extends UFS file systems

       /sbin/extendfs [-s  disk_blocks]	 device_name

       Specifies the total number of 512-byte blocks for the UFS file system.


	      This  value  is  not  an increment. Specifying a value with this
	      option does not increment the file system by that value; rather,
	      it is the new size of the file system.

       Use  the	 extendfs  command to increase the storage space in a UFS file
       system.	The file system must not be  mounted  when  you	 perform  this
       operation.  To extend a mounted (in use) UFS file system, use the mount
       command with the -u -o extend mnt_point parameters.

       The procedure for increasing the storage space of a UFS file system  is
       as follows: Look at the contents of the /etc/fstab file to identify the
       disk partition that maps to the file  system.   Ensure  that  there  is
       available storage space on the target disk as follows: If LSM is in use
       on your system, use LSM commands to increase the size of the LSM volume
       as  described  in  the Logical Storage Manager guide.  If LSM is not in
       use on your system, use the disklabel command or the diskconfig graphi‐
       cal  user  interface to check the current size and use of partitions on
       the disk.  If there is adequate space on an adjacent partition, use the
       disklabel  command  to  write the current label to a file as follows: #
       disklabel -r dsk4 > d4label Edit the disklabel file to change the  size
       of  the	partition on which your UFS file system resides.  Increase the
       number of disk blocks on the partition and decrease the disk block size
       of  the	adjacent partition by an equivalent number.  Use the disklabel
       command with the -R option to write the revised label to the  raw  disk
       as follows: #  disklabel -R /dev/rdisk/dsk4 d4label When the disk label
       is revised, extend the file system using the extendfs command.  You can
       either  use  the full extent of the newly sized partition or extend the
       file system in stages.  The following example commands show both	 meth‐
       ods.   To  extend  the  file system to use all the available space, you
       specify the disk partition on which the file system  resides,  as  fol‐
       lows: #	extendfs /dev/disk/dsk4g To extend the file system to use only
       part of the available space, you	 specify  the  total  number  of  disk
       blocks to be used, as follows: #	 extendfs -s 300000 /dev/disk/dsk4g

	      The  remainder  of  the  extended partion is reserved for future

       You can extend a file system as many times  as  necessary,  up  to  the
       physical	 limit of the storage device.  When no more space is available
       on the storage device, you must back up the file system using the  dump
       command	and  restore the file system to a storage device that has more
       available space.

       Once you have extended a file system, the operation cannot be  reversed
       except by a back up and restore operation. Use the dump command to back
       up the file system.  You can then reset the  partition  sizes  manually
       and restore the file system to the storage device.

       The disklabel command produces output similar to that of the newfs com‐
       mand. If a list of disk blocks is not displayed on  the	terminal,  the
       command has failed.  Verify the partition settings and the mount status
       of the target file system.

       The disklabel command does not permit you to overwrite a	 partition  if
       it is in use.  Refer to the disklabel(8) reference page for more infor‐
       mation on label errors.

       Specifies the command path.

       diskconfig(8), disklabel(8), mount(8), and fstab(4).
