Path Name: /hp-ux_patches/s700_800/10.X/PHCO_18868

Symptoms:
	PHCO_18868:
	1. The fsck(VxFS) does not insert unreferenced files in the
	    lost+found directory.

	2. For very big filesystems, fsck(VxFS) does not attempt to
	   read all the alternate copies of the superblock when
	   needed.

	PHCO_17671:
	No external symptoms, just removal of unnecessary code

Defect Description:
	PHCO_18868:
	1. The fsck(vxfs) always skips the addition of a file in the
	   lost+found directory.

	2. The header of each AU of filesystem keeps the static
	   information of the superblock along with the other
	   information. The header of all the AUs are kept in a
	   structural file.  The datablocks of this file may reside
	   in any of the FS blocks reserved for the structural
	   files.  The fsck(vxfs) tries to search for the
	   alternate superblock in the first 128 * 64 = 8192 FS
	   blocks irrespecive of the filesystem size. But for very
	   large filesystems, more than 8192 FS blocks are reserved
	   for structural files. It means that fsck does not
	   attempt to read all the alternate copies of the
	   superblocks.

	Resolution:
	1. The fsck(vxfs) has been modified to add a file in
	   lost+found directory in case all the four conditions are
	   satisfied:
	   a. The lost+found directory exists.
	   b. lost+found is not a multilevel directory.
	   c. lost+found is not having wildcard sensitivity label.
	   d. lost+found dominates the sensitivity label of the
	      file.

	2. The fsck(vxfs) has been changed to search for the
	   alternate superblock in the first 512 * 64 = 32768 FS
	   blocks. It is the maximum size of an allocation unit.

	PHCO_17671:
	fsck had unnecessary and unused code

	Resolution:
	1. Port PHCO_16591
	2. merged in Top of Trunk for vxfs/fsck

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHCO_18868.depot

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHCO_18868.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHCO_18868.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHCO_18868.depot of=/dev/rmt/0m bs=2k
