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.
