OCFS The system hangs or
displays a kernel
panic message.
The Red Hat Linux system
by default has a daily cron
job routine set up to
perform updatedb on
certain file systems in
/etc/cron.daily and
/etc/updatedb.conf. OCFS
does not support updatedb
on its file systems.
1 Edit the /etc/cron.d/slocate.conf file
and add
ocfs to the excluded file
system list. The file should resemble
the following:
#!/bin/sh
renice +19 -p $$
>/dev/null 2>&1
/usr/bin/updatedb -f "ocfs
nfs,smbfs,ncpfs,proc,devpt
s" -e
"/tmp,/var/tmp,/usr/tmp,/a
fs,/net"
2 Edit the /etc/updatedb.conf file and
add
ocfs to the PRUNEFS list. The
file should resemble the following:
PRUNEFS="ocfs devpts NFS
nfs afs proc smbfs autofs
auto iso9660"
PRUNEPATHS="/tmp /usr/tmp
/var/tmp /afs /net"
export PRUNEFS
export PRUNEPATHS
OCFS OCFS does not
recognize newly
replaced NIC.
If you change the NIC
whose name is listed in
/etc/ocfs.conf, you must run
ocfs_uid_gen -r to
update the MAC address in
the /etc/ocfs.conf file before
you can mount OCFS
volumes.
If you replace the NIC whose IP address
is listed in /etc/ocfs.conf, type
ocfs_uid_gen -r before you load
the OCFS driver or mount OCFS
partitions.
OCFS Large file copy,
move, dd, and other
operations on
OCFS files cause
system to hang
occasionally.
The default fileutils package
does not support o_direct
file operations, which are
required by OCFS files.
Download the latest OCFS supported
fileutils package from the Oracle
Technology Network.
NETCA NETCA fails,
resulting in
database creation
errors.
The public network,
hostname, or virtual IP is
not listed in the
/etc/hosts.equiv file.
Before launching netca, ensure that a
hostname is assigned to the public
network and that the public and virtual
IP addresses are listed in the
/etc/hosts.equiv file.
