Dear folks,
I have the following problem while creating a cluster and mounting an ebs volume
on /data. Here is the config file part corresponding to my template:
[cluster issm]
# change this to the name of one of the keypair sections defined above
KEYNAME = ISSMStarCluster
# number of ec2 instances to launch
CLUSTER_SIZE = 2
# create the following user on the cluster
CLUSTER_USER = sgeadmin
# optionally specify shell (defaults to bash)
# (options: tcsh, zsh, csh, bash, ksh)
CLUSTER_SHELL = bash
# AMI to use for cluster nodes. These AMIs are for the us-east-1 region.
# Use the 'listpublic' command to list StarCluster AMIs in other regions
# The base i386 StarCluster AMI is ami-899d49e0
# The base x86_64 StarCluster AMI is ami-999d49f0
# The base HVM StarCluster AMI is ami-4583572c
NODE_IMAGE_ID = ami-4583572c
# instance type for all cluster nodes
# (options: cg1.4xlarge, c1.xlarge, m1.small, c1.medium, m2.xlarge, t1.micro, cc1.4xlarge, m1.medium, cc2.8xlarge, m1.large, m1.xlarge, hi1.4xlarge, m2.4xlarge, m2.2xlarge)
NODE_INSTANCE_TYPE = cc2.8xlarge
# Uncomment to disable installing/configuring a queueing system on the
# cluster (SGE)
#DISABLE_QUEUE=True
# Uncomment to specify a different instance type for the master node (OPTIONAL)
# (defaults to NODE_INSTANCE_TYPE if not specified)
#MASTER_INSTANCE_TYPE = m1.small
# Uncomment to specify a separate AMI to use for the master node. (OPTIONAL)
# (defaults to NODE_IMAGE_ID if not specified)
#MASTER_IMAGE_ID = ami-899d49e0 (OPTIONAL)
# availability zone to launch the cluster in (OPTIONAL)
# (automatically determined based on volumes (if any) or
# selected by Amazon if not specified)
#AVAILABILITY_ZONE = us-east-1c
# list of volumes to attach to the master node (OPTIONAL)
# these volumes, if any, will be NFS shared to the worker nodes
# see "Configuring EBS Volumes" below on how to define volume sections
VOLUMES = issm
# Sections starting with "volume" define your EBS volumes
[volume issm]
VOLUME_ID = vol-7d113b07
MOUNT_PATH = /data
when I first start this cluster:
starcluster start issm, everything works perfectly.
start issm

The cluster is now ready to use. To login to the master node
as root, run:
$ starcluster sshmaster issm
I checked, /data is correctly mounted on my ebs volume, everything fine.
Here is an frisk dump:
root_at_master:/data# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 8246240 5386292 2441056 69% /

/dev/xvdz 103212320 192268 97777172 1% /data
the ebs volume I'm mounting is 100Gb in men, so everything checks out.
Now, if I stop the cluster, and start it again using the –x option, the cluster will boot
fine, but will not attach to the volume (won't attempt it at all) and will not even try
to mount /data. It's as though the [volumes] section of my config did not exist!
Here is the output of the starcluster start –x issm command:
st start -c issm -x issm

As you can see, no attempt was made at attaching to the ebs volume, and mounting of
/data was not attempted! When I log in, there is no ebs volume device for /data either
Any help or pointers would be appreciated!
Thanks in advance!
