Veritas File System 5.0.1 Release Notes

mount this file system locally (without the -o cluster mount option) and upgrade the
disk layout to version 6 or 7 before mounting it with the -o cluster mount option.
• I/O error mount options
In this and future releases, only the ioerror=disable and ioerror=mdisable mount
options are supported for clustered file systems. Other ioerror mount options are not
supported. For more information, see mount_vxfs(1M).
Known Limitations
The following are the software limitations in Veritas File System 5.0.1:
• Quick I/O, ODM, mount -o cio, and the VX_CONCURRENT advisory are mutually
exclusive
The VX_CONCURRENT advisory cannot be set on a file that is actively open by Quick I/O or
ODM. A file that has the VX_CONCURRENT advisory set may not be concurrently opened by
Quick I/O or ODM. Quick I/O and ODM access are not allowed for any files on a file system
that is mounted with the mount -o cio option.
Known Problems and Workarounds
Following known problems exist for VxFS 5.0.1:
NOTE: For information on the Known Problems and Workarounds in VxFS 5.0 in the HP-UX
11i v3 operating system, see Veritas File System 5.0 Release Notes, HP-UX 11i v3, First Edition, May
2008 available at http://www.docs.hp.com.
• Problem
File Change Log tunable setting for proper functioning of Dynamic Storage Tiering
applications
Workaround
If the active placement policy of a given file system uses I/O or access temperatures, after
the policy becomes active by being assigned, you must tune the fcl_malloc tunable of
the file system with the following command:
# vxtunefs -o fcl_maxalloc=0 mount_point
However, if any application other than DST uses FCL, this setting may conflict with those
applications.
• Problem
If an ANSI C compiler is installed on a system before installing the 5.0.1 bundles, the following
swverify errors may be displayed after installing the 5.0.1 bundles.
==========================================
ERROR: Symlink "/usr/bin/cc" should have value "/usr/ccs/bin/cc" but
the actual value is "/opt/ansic/bin/cc".
ERROR: Fileset "OS-Core.C-KRN,l=/,r=B.11.31" had file errors.
==========================================
Workaround
You can ignore these error messages because these messages are harmless messages and do
not impact any functionality on the system.
