df and bdf discrepencies

[HP-UX 10.20 with latest GR from hp installed]

I've recently had some space problems on one of our old HP9000 machines. I archived/moved/compressed/trashed some stuff to free up some space on one rather large (and important) logical volume.

As one would expect, when `df -b` is executed some space is shown as free:

/opt (/dev/vg00/lvol5 ) : 509218 Kbytes free

However, space problems are still reported on this volume. Trying another tact I execute `bdf` to ensure that space really has been freed up:

Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol5 6866069 6356851 0 100% /opt

hmmm. Now I deleted the stuff by hand, and the figure reported by 'df -b' sounds ok. To further complicate things,
plain 'ol `df` reports:

/opt (/dev/vg00/lvol5 ): 0 blocks 1020265 i-nodes

And I should add the fsck reports that all is hunky-dory.....

(a) can anybody give me some idea of what is going on Smilie

(b) how can I resolve this so that me free space is recognised?

*any* help appreciated and further information supplied on request. Thanks.

lvremove

LVREMOVE(8)						      System Manager's Manual						       LVREMOVE(8)

NAME

       lvremove - remove a logical volume

SYNOPSIS

       lvremove [-A|--autobackup y|n] [-d|--debug] [-f|--force] [-h|-?|--help] [-t|--test] [-v|--verbose] LogicalVolumePath [LogicalVolumePath...]

DESCRIPTION

       lvremove  removes  one  or  more  logical  volumes.   Confirmation will be requested before deactivating any active logical volume prior to
       removal.  Logical volumes cannot be deactivated or removed while they are open (e.g. if they contain a mounted  filesystem).   Removing	an
       origin logical volume will also remove all dependent snapshots.

       If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com-
       mand issued from one node can do this.

OPTIONS

       See lvm(8) for common options.

       -f, --force
	      Remove active logical volumes without confirmation.

EXAMPLES

       Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation:

	    lvremove -f vg00/lvol1

       Remove all logical volumes in volume group vg00:

	    lvremove vg00
