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. 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 determines how much disk space is required. If there isn't sufficient space, swcopy reports an error:

ERROR: The used disk space on filesystem "/var" is estimated
to increase by 57977 Kb.
This operation will exceed the minimum free space for this
volume.  You should free up at least 10854 Kb 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.

Follow these steps to increase the size limit of /var:

Determine if any space is available by entering:

/sbin/vgdisplay

You should see a display like this:

         - 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

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

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

Enter: /sbin/mount

You will see a display similar to this:

/ 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.
Enter: /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:

/sbin/lvextend -L new_size_in_MB /dev/vg00/lvol7
For example, this makes the volume 332 MB:
/sbin/lvextend -L 332 /dev/vg00/lvol7
Extend the file system size to the logical volume size:
/sbin/extendfs /dev/vg00/rlvol7
Enter: /sbin/mount /var
Either go back to the regular init state,init 3 orinit 4, or reboot.
