[Linux-cluster] Can't create new GFS storage

[Doug Sharp]

Mike, I just finished creating a GFS1 filesystem on a SAN LUN.  Here is the process I used.  Maybe it will help:

0. Made sure cman, clvmd, gfs, and rgmanager services were running
1. # lvmdiskscan - make sure SAN LUN appears.  In my case it was sdb
2. # pvcreate /dev/sdb 
3. # vgcreate oravg /dev/sdb  
4. # lvcreate -L 16G -n oralv oravg  => creates /dev/oravg/oralv as a 16GB LUN
5. # gfs_mkfs -p lock_dlm -t tora-cluster:orat -j 4 /dev/oravg/oralv  => makes a gfs1 filesystem 
6. # mkdir /orat
7. # mount /dev/oravg/oralv /orat

HTH
Doug

I was able to create a small partition but had to do it via webmin? Still, 
something is not right.
