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,devpts"
-e "/tmp,/var/tmp,/usr/tmp,/afs,/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.
