Patch Name: PHKL_13862

Patch Description: s700 10.10 Fix for unmountable VxFS (JFS) file systems

Creation Date: 98/01/19

Post Date:  98/01/28

Hardware Platforms - OS Releases:
	s700: 10.10

Products: N/A

Filesets:
	JournalFS.VXFS-BASE-KRN

Automatic Reboot?: Yes

Status: General Release

Critical:
	Yes
	PHKL_13862: OTHER
			Unmountable VxFS (JFS) file system.

Path Name: /hp-ux_patches/s700/10.X/PHKL_13862

Symptoms:
	PHKL_13862:
	After a hard failure (panic/hang/TOC), a JFS file system may
	not mount and will return the following error message:

	vxfs mount: %s is not a vxfs file system.

	A full fsck does not clean the file system; a newfs/mkfs is
	the only solution.

Defect Description:
	PHKL_13862:
	If the VX_IETRUNC flag is set for a file, then vx_trunc() is
	called and returns without clearing the ip->i_eopflags
	field.  Since VX_IETRUNC alone is still set after
	vx_trunc(), the error return is set to EINVAL (reason why
	the mount fails).  Prior to returning, if error is non-zero,
	vxfs sets the VX_FULLFSCK flag and returns.

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_13862

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHKL_13862.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_13862.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_13862.  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_13862.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_13862.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	This is a JFS patch that should not be  installed on systems
	using  the  OmniStorage   product.  If  you  are  using  the
	OmniStorage  product then using the methods taken to receive
	this patch  please  obtain  the  equivalent  OmniStorage/JFS
	patch.  If you cannot locate the patch, please  contact your
	local HP support entity.
