Hi guys,
I got into an problem while using GFS with DLM on Fedora Core 4.
Every thing is working fine, the boot process, the mounting of the GFS
volume, the reading of the journals,
until I try to read files from that volume. And from then the GFS hangs.
I tried to look into the system logs but there I can't find anything.
The only thing that I find it different from my other cluster wich is
based on Ubuntu, is the content of
/proc/cluster/dlm_debug
On FC4 :
[root@cluster01 ~]# cat /proc/cluster/dlm_debug
6 finished
clvmd move flags 1,0,0 ids 15,15,15
clvmd move flags 0,1,0 ids 15,20,15

And on Ubuntu:

So I thought that this is and DLM locking problem, so I started to look
for clues
[root@cluster01 ~]# lsmod | grep dlm
lock_dlm 42084 1
lock_harness 4392 2 lock_dlm,gfs
dlm 118220 5 lock_dlm
cman 130208 21 lock_dlm,dlm
[root@cluster01 ~]# dmesg | grep dlm
dlm: no version for "struct_module" found: kernel tainted.
GFS: Trying to join cluster "lock_dlm", "cluster:data"
The packages that are installed are:
[root@cluster01 ~]# rpm -qa | grep dlm
dlm-kernel-2.6.11.5-20050601.152643.FC4.17
dlm-kernheaders-2.6.11.5-20050601.152643.FC4.17
dlm-devel-1.0.0-3
dlm-1.0.0-3
And the machine is
[root@cluster01 ~]# uname -a
Linux cluster01 2.6.14-1.1653_FC4 #1 Tue Dec 13 21:32:09 EST 2005 i686
i686 i386 GNU/Linux
Right now I don't know for sure which is the problem. I hope that
someone can explain me what I did wrong.
Thanks in advance for your help.
Costi.
