Path Name: /hp-ux_patches/s700_800/10.X/PHCO_18804

Symptoms:
	PHCO_18804:
	Ported from 10.20 patch PHCO_10578 for TOS.
	When trying to use extendfs to create/enlarge to
	a large hfs file system, extendfs would appear to work,
	but print the message
	   ERROR -- we are writing to the wrong fragments
	and the file system would be corrupted.  This problem
	is seen only for extending file systems larger than 40GB.

Defect Description:
	PHCO_18804:
	Ported from 10.20 patch PHCO_10578 for TOS.
	When extending the cylinder area needed for large file
	systems, extendfs could possibly corrupt the file system
	while enlarging it, forcing the customer to either
	fsck and restore the file system, or possibly need to
	do a newfs.
