There are some errors when trying to install a node and the following error from rocks list host profile is probably causing it. We have run xmllint against our extend-compute.xml and replace-partition.xml and there were no errors. Any ideas on how to fix this would be appreciated.

# rocks list host profile compute-0-0

If you remove your extend-compute.xml and/or replace-partition.xml and
rebuild the distro, does the problem go away?
if yes, then send your extend-compute.xml and/or replace-partition.xml file
and we'll take a look at it.

Try:

# ROCKSDEBUG=y rocks list host profile compute-0-0

Then look at the last couple lines -- it should be obvious in which
node XML file and which line the syntax error is on.

Removing the extend-compute.xml and replace-partition.xml and rebuilding ends up with the same messages.

Same results as before with ROCKSDEBUG.
Forgot to put that this is ROCKS 5.4.3.

# ROCKSDEBUG=y rocks list host profile compute-0-0

We found the problem. There was an attribute in the database for each node that had a % in it. We removed that attribute and now everything is working.

Thanks.

Does anyone have additional documentation for insert-ethers. The --help only reveals the potential of the command.

./sbin/insert-ethers --help
Insert Ethernet Addresses - version 5.4
Usage: insert-ethers [-hv] [-p password] [-u host] [-d database] [--help]
[--list-rcfiles] [--list-project-info] [--verbose] [--update] [--staticip]
[--rcfile arg] [--host host] [--password password] [--db database]
[--user host] [--baseip ip address] [--basename basename] [--hostname hostname]
[--ipaddr ip address] [--cabinet number] [--rack number] [--inc number]
[--rank number] [--replace hostname] [--remove hostname]
[--os the OS to install on the machines]


Thanks

What do you want to do? Then I can help guide you through the menagerie of
flags :-(.

We want to add IPMI interfaces /hostnames that match the compute node number.

compute-0-59 would relate to power-0-59

Since we are adding new nodes, we would like to insert-ethers to start at the same node number as the compute node and continue on. Since we have no power-0-xx names, insert-ethers wants to start at power-0-0 and our compute nodes are at 0-59 . I can do them one at a time by insert-ethers -- hostname power-0-59 , but it is time consuming for a whole rack of nodes.

I was hoping to start insert-ethers and then plug in the network inferface one at time while they are discovered and assigned a name.

Thanks
Mike

We handle this a bit differently by making the IPMI interface a host
interface.
Do the following ONCE
# rocks add network ipmi <subnet> netmask=<netmask>

for each host
# rocks add host interface <host> ipmi subnet=ipmi ip=<ip address>

Then
# rocks sync config
# rocks sync host network compute


If you look at the python script at
http://git.rocksclusters.org/cgi-bin/gitweb.cgi?p=triton/scar/.git;a=blob;f=src/root-scripts/sbin/addInterface;h=d07652082875e986816467e73f511773d7f7116c;hb=e2497feb8e350a28042436408fb95ea974c8cb40

this is a local utility we wrote to match the last octets so that different
subnets on the same host have the
same last octets.

If you want to go the insert ethers way, then use the rank option
eg insert-ethers --rank=59
to begin at rank 59.
(please test that we assign the rank first and then increment, rather than
the other way around)
