[Ocfs-users] Mouting Filesystem problems

Thu Mar 10 14:00:03 CST 2005

ocfs probably sets the node id when it loads the ocfs.o kernel module. 
i bet you need to reboot so that the ocfs kernel module is reloaded
after changing the config file.

Hi, 

here is what I did now

on one of the nodes

vi /etc/ocfs.conf
 removed the node name parameter value

[root at LNCSTRTMIT03 etc]# more ocfs.conf
#
# ocfs config
# Ensure this file exists in /etc
#

        node_name = lncstrtmit03
        node_number =
        ip_address = 10.85.151.21
        ip_port = 7000
        comm_voting = 1
        guid = DF961E85CB3A49C9F7CD000E7FAF2AC4

[root at LNCSTRTMIT03 etc]# cd /etc/init.d
[root at LNCSTRTMIT03 init.d]# ./ocfs stop
[root at LNCSTRTMIT03 init.d]# ./ocfs start
Loading OCFS:                                              [  OK  ]

[root at LNCSTRTMIT03 init.d]# mkfs.ocfs -F -b 1024 -g root -u root -L
OCSF1 -m /ocfs1 -p 755 /dev/sda
Cleared volume header sectors
Cleared node config sectors
Cleared publish sectors
Cleared vote sectors
Cleared bitmap sectors
Cleared data block
Wrote volume header

[root at LNCSTRTMIT03 init.d]# mount -t ocfs /dev/sda /ocfs1
mount: wrong fs type, bad option, bad superblock on /dev/sda,
       or too many mounted file systems

[root at LNCSTRTMIT03 init.d]# fsck.ocfs /dev/sda
fsck.ocfs 1.1.2-PROD1 Fri Apr  2 13:59:23 PST 2004 (build
2df841d19c031db220f8cfb73439339d)
Checking Volume Header...
Volume has never been mounted on any node. Exiting
/dev/sda: clean, 0 objects, 0/20478 blocks

Also tried it with the parameter completely gone and with a value of
0, same errors
