Re: [Linux-cluster] make errors for 2.6.19 on fc6

Thanks man.
The reason for not switching to vanilla(2.6.20 and i have it installed) is , i am running iscsi-target for 2.6.19.I got similar make errors for gfs and gfs2 programs.but i left them by marking the lines in make file as commands, as i installed gfs2-utils rpm from update yum repository and i am gonna to only use gfs2.The installation is successful.
but when i do,
[root server ~]# dlm_controld
[root server ~]#  modprobe lock_dlm
WARNING: Error inserting debugfs (/lib/modules/2.6.19-1.2911.fc6/kernel/fs/debugfs/debugfs.ko): Invalid module format

[root server ~]# ccsd

Hint: ccsd is already running.

where i am missing?

out of curiosity:you referenced me a web based diff tool at redhat site.how can i find the version of a source file with respec to kernel .For example: glock.c contains no version information inside it!

Thanks and regards,
Nirmal Tom.V

Thanks a lot to both Sridhar and Rafael.Now gfs-kernel stucks, i think.

on both stable and development, i got this.how to fix this one?

Hi Nirmal,

This has to do with changes made to the upstream kernels, which our STABLE
and HEAD branches of CVS track. In 2.6.19, the "struct delayed_work" was "struct work_struct" and "INIT_DELAYED_WORK" was "INIT_WORK". There was also a change in what was passed. The following diff shows the change made to bring glock.c up to the newer kernels (HEAD branch):


If you really don't want to upgrade to a newer kernel, you could back out the last change I did, at least to glock.c. To compare them, also see:
