Adjusting File System Size

The absolute minimum /usr file-system sizes needed to update to HP-UX 11.0 are:

For 32-bit: 300 MB.
For 64-bit: 324 MB.

If the required file-system size for the bundle you copy to a depot exceeds that file system limit set by your disk installation, you will get an error condition during the copy process. You can use lvextend and extendfs in this situation to create a larger file system.

You might have a problem updating your system(s) if the/usr or /var volume is too small.

If you try an update, swcopy will determine how much disk space is required. If there isn't sufficient space, swcopy will report an error like this:

                 ERROR: The used disk space on filesystem "/var" is estimated
                 to increase by 57977 Kbytes.
                 This operation will exceed the minimum free space for this
                 volume.  You should free up at least 10854 Kbytes to avoid
                 installing beyond this threshold of available
                  user disk space.

In this example, you would need to increase the file system size of /var by 10 MB, which actually needs to be rounded up to 12 MB.

The following are the steps required for increasing the size limit of /var:

Determine if any space is available by entering the following:

/sbin/vgdisplay

You should see a display like the following:

           - Volume groups -
      VG Name                     /dev/vg00
      VG Write Access             read/write
      VG Status                   available
      Max LV                      255
      Cur LV                      8
      Open LV                     8
      Max PV                      16
      Cur PV                      1
      Act PV                      1
      Max PE per PV               2000
      VGDA                        2
      PE Size (Mbytes)            4
      Total PE                    249
      Alloc PE                    170
      Free PE                     79
      Total PVG                    0

The "Free PE" indicates the number of 4 MB extents available, in this case this is 79 (equivalent to 316 MB).

Enter the following:
/sbin/shutdown
Change to single user state. This will allow /var to be unmounted.

Enter the following:

/sbin/mount

You will see a display similar to the following:

                 / on /dev/vg00/lvol1 defaults on Sat Mar 8 23:19:19 1997
                  /var on /dev/vg00/lvol7 defaults on Sat Mar 8 23:19:28 1997

Determine which logical volume maps to /var. In this example, it is /dev/vg00/lvol7.
Execute the following command:
/sbin/umount /var
This is required for the next step, since extendfs can only work on unmounted volumes.
Extend the size of the logical volume by entering the following:
/sbin/lvextend -L new_size_in_MB /dev/vg00/lvol7
This extends the size of the logical volume.
For example,
/sbin/lvextend -L 332 /dev/vg00/lvol7
This will make this volume 332 MB.
Execute the following command:
/sbin/extendfs /dev/vg00/rlvol7
This extends the file system size to the logical volume size.
Finally, execute the following commands:
/sbin/mount /var
Go back to the regular init state: init 3 or init 4. Or you can reboot.
