Pinned topic MVFS not loading.

‏2013-01-31T18:33:24Z |
Hi,

I am currently configuring a linux server for clearcase and I am facing trouble in configuring MVFS on the server.

After installation I faced the below error when I tried to start clearcase

ClearCase daemons: albd_server FATAL: Error inserting mvfs (/lib/modules/2.6.16.60-0.85.1-ppc64/kernel/fs/mvfs/mvfs.ko):
Invalid module format
Loading the MVFS was unsuccessful(8:1)
/opt/rational/clearcase/etc/clearcase: Loading MVFS failed
  • Please review /var/log/messages for information on the problem.
  • You may need to rebuild your kernel, rebuild your mvfs module,
  • and reboot your system. Information on how to do this can be found in
  • your Release Notes and file /var/adm/rational/clearcase/mvfs/mvfs_src/README.txt

I rebuilt the mvfs module as mentioned in the README.txt and when I tried starting clearcase I get the below error

ClearCase is stopped
Starting ClearCase
ClearCase daemons: albd_server The ClearCase mvfs file system will not be loaded.
The mvfs is also not listed when I check for the version.

/usr/atria/bin/cleartool -version
ClearCase version 7.1.2.1 (Fri Dec 17 17:22:14 EST 2010) (7.1.2.01.00_2010D.FCS)
ClearCase version 7.1.2.2 (Tue Mar 29 16:47:51 EST 2011) (7.1.2.02.00_2011A.FCS)
ClearCase version 7.1.2.3 (Wed Jun 08 22:31:05 EDT 2011) (7.1.2.03.00_2011B.D110608)
ClearCase version 7.1.2.4 (Mon Aug 22 23:31:06 EDT 2011) (7.1.2.04.00_2011C.D110822)
cleartool 7.1.2.4 (Tue Aug 9 00:44:35 2011)
db_server 7.1.2.4 (Tue Aug 9 00:45:16 2011)
VOB database schema version: 54

The version of the kernel in the server is 2.6.32.54-0.3-default
Is this error due to the version of kernel or am I doing something wrong during installation? The version of kernel on the servers where it is working correctly is 2.6.32.43-0.4-default

The server was also restarted after rebuilding the mvfs module.

Please help me.

Regards,
Dinil

    The first question here is: "Which Linux?" It looks like you're running SLES 11 SP1 on System Z. Is that correct? That kernel release is an errata release dated February 2012 (See Suse Linux Kernel versions)

    Are there any errors or warnings in your make output? I ask because it appears that your initial attempt tried to load an MVFS for the wrong kernel version, and it looks like the MVFS either did not build correctly or the one of the make phases did not occur.

    You may want to update to a ClearCase version that is newer than the kernel you have installed and trying again. Since that is the release just before the SP2 release, try 7.1.2.7 since it has SLES11 SP2 support.

      Hi,

      Thank you for the reply.

      Yes we are running SLES 11 SP1 on the server. I did not get any errors or warning in make output.

      Will reverting to the kernel version 2.6.32.43-0.4-default help resolve the issue?

        Hi,

        Thanks for the replies and help. It was an issue of improper configuration of Linux. Got the linux reinstalled and everything fell in place.
