Re: [Linux-cluster] GFS Problem



Jos,
Im answering one by one

> -  Did you create the GFS filesystems with the correct locking
>    protocol (lock_dlm)?
Yes i did, like the documentations says: 
gfs_mkfs -p lock_dlm -t cluster_eseia:portales -j 4 /dev/CLUSTERLVM/portales

I used 4 journal, cause we are hoping to add 2 more nodes soon.

> -  Do you use clvmd?  Did you mark your VG's to be "clustered" and
>    do you have "locking_style = 3" in /etc/lvm/lvm.conf?

No i did not. By the way i only have locking_type in the file, i suppose is what you meant. Righ now is:
locking_type = 1

They arent, because they are supposed to start right away the server boot, and the services i have: IP and Perlbal, do not use the GFS filesystems.


In my logs files i saw this:
