Patch Name: PHKL_12339

Patch Description: s700 10.20 VxFS (JFS) fsck(1M) cumulative patch

Creation Date: 97/09/04

Post Date:  97/09/09

Hardware Platforms - OS Releases:
	s700: 10.20

Products: N/A

Filesets:
	JournalFS.VXFS-BASE-KRN

Automatic Reboot?: Yes

Status: General Superseded

Critical:
	Yes
	PHKL_12339: HANG
	PHKL_12007: CORRUPTION

Path Name: /hp-ux_patches/s700/10.X/PHKL_12339

Symptoms:
	PHKL_12339:
	Mounting a VxFS Version 2 filesystem containing a large
	amount of files (in excess of 800,000) can take several
	minutes to complete. During the time it takes to mount
	the filesystem the system appears to be hung.

	This patch provides improved kernel routines which
	eliminate this performance problem.

	PHKL_12007:
	10.20 fsck on vxfs (version 3) filesystem fails with
	 the following error:
	  # fsck -o full -y /dev/vg01/lvol3
	  pass0 - checking structural files
	  pass1 - checking inode sanity and blocks
	  pass2 - checking directory linkage
	  pass3 - checking reference counts
	  pass4 - checking resource maps
	  small extent in iau inode
	This occured after a normal shutdown.  The filesystem
	is unusable and must be newfs'd.
	This patch provides the kernel half of a solution for an
	fsck defect.  The commands patch PHCO_11908 must also be
	applied to install the full solution.  Without PHCO_11908
	installed, this patch will have no impact.

Defect Description:
	PHKL_12339:
	Mounting a version 2 VxFS filesystem containing many
	(>800K) files takes several minutes.

	PHKL_12007:
	this is the kernel part of the solution to that fsck problem
	that PHCO_11908 addresses.  It involves a VxFS filesystem.

Installation Instructions:
	Please review all instructions and the Hewlett-Packard
	SupportLine User Guide or your Hewlett-Packard support terms
	and conditions for precautions, scope of license,
	restrictions, and, limitation of liability and warranties,
	before installing this patch.
	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHKL_12339

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHKL_12339.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHKL_12339.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHKL_12339.  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.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHKL_12339.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/PHKL_12339.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	The kernel patch PHKL_12008 provides the kernel half of a
	solution for an fsck defect.  The commands patch PHCO_11908
	must also be applied to achieve the full solution.  Without
	PHCO_11908 installed, this patch will have no impact.

	The kernel patch PHKL_12007 provides the kernel half of a
	solution for an fsck defect.  The commands patch PHCO_11908
	must also be applied to achieve the full solution.  Without
	PHCO_11908 installed, this patch will have no impact.
