It looks like you are not using pool.
You seem to have divided up the storage sanely. However, rather than forming a pool logical volume on the partitions you've created and then putting ccs and gfs on the pool volumes, you have simply put ccs and gfs directly on the underlying device. This is not terrible if you can ensure that your devices will _always_ have the same name, regardless of the machine you are viewing them from. (Pool's main function is to write labels to the underlying devices so that they can be uniquely identified on every machine in the cluster.)
So, at this point, you can choose to forget about using pool and proceed as you have started; or you can set up your pools first and put ccs and gfs on them (this is the method normally used).
If you choose to set up pools, you would do something like:
# create config files for two different pools (one for ccs and one for gfs)
prompt> cat > cca_pool.cfg
poolname cca
subpools 1
subpool 0 0 1 gfs_data
pooldevice 0 0 /dev/cciss/c0d1p1
prompt> cat > gfs1_pool.cfg poolname gfs1 subpools 1 subpool 0 0 1 gfs_data pooldevice 0 0 /dev/cciss/c0d1p2
#Write the labels to disk - remember this only needs to be done once prompt> pool_tool cca_pool.cfg prompt> pool_tool gfs1_pool.cfg
#Instantiate the pool logical volumes prompt> pool_assemble
#Now you have block devices called /dev/pool/cca and /dev/pool/gfs1 # create your CCS archive and gfs file system on these devices prompt> ccs_tool create /root/cluster /dev/pool/cca prompt> mkfs.gfs ... /dev/pool/gfs1

Hello!
We bought HP ProLiant DL380 G4 Packaged Cluster-MSA500 G2 server and after installation of RHEL3 and GFS-6.0.0-15 I have some questions.
Because I have no expirience in setting up such systems, please, tell me, which mistakes in configuration I made.
Now system is configured this way:
/dev/cciss/c0d1 - External Logical Volume, 293.6 Gbytes (RAID 5)
=================== [root@hp1 root]# fdisk /dev/cciss/c0d1 Command (m for help): p
Disk /dev/cciss/c0d1: 293.6 GB, 293626045440 bytes 255 heads, 63 sectors/track, 35698 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/cciss/c0d1p1 1 9 72261 fd Linux raid autodetect
/dev/cciss/c0d1p2 10 35698 286671892+ fd Linux raid autodetect
I've found nothing in GFS documentation about partitioning hard drive during setting up GFS. So, I used to experiment.
First partition is allocated for <- CCA device ->. I'd like to know if there is enough space and right type of partition, and, at all, is it right way to allocate <- CCA device ->.
Second partition was formatted as GFS, so the question is: is selected type of partition right or not?
===================
[root@hp1 root]# cat pool0.cfg poolname pool0 minor 0 subpools 2 subpool 0 0 1 gfs_journal pooldevice 0 0 /dev/cciss/c0d1p1 subpool 1 0 1 gfs_data pooldevice 1 0 /dev/cciss/c0d1p2
Actually, I don't know why, but first subpool I've made as gfs_journal :-)
Basically, the system works, but something may be wrong.
=================== During setting up I've made this command:
[root@hp1 root]# ccs_tool create /root/cluster/ /dev/cciss/c0d1p1
[root@hp1 root]# pool_tool -s Device Pool Label ====== ========== /dev/cciss/c0d0 <- partition information -> /dev/cciss/c0d0p1 <- EXT2/3 filesystem -> /dev/cciss/c0d0p2 <- swap device -> /dev/cciss/c0d0p3 <- EXT2/3 filesystem -> /dev/cciss/c0d1 <- partition information -> /dev/cciss/c0d1p1 <- CCA device -> /dev/cciss/c0d1p2 <- GFS filesystem ->
I'd like to hear some comments on it.
===================
Thanks.
