[Linux-cluster] some questions about setting up GFS


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.
