Jarrod,
Sorry. The rsetboot isn't taking a long time. It's just nodeset that
is. I cut/pasted a group of commands into the terminal for the system I was
working on (nodeset, rsetboot, rpower) and it hung on nodeset. So, there is
something going wrong with nodeset. I have another xCAT iDataplex cluster
(my testing cluster) which I upgraded to 2.8.4 and it isn't having a
problem:

Granted my test cluster is only a few nodes. But still, it's updating
everything correctly. I also noticed that the node I put through discovery
on 2.8.4 showed discovery method as "UNDEF" according to nodediscoverls:
# nodediscoverls | grep c4u34
18F64EE1-3CC1-DF11-B526-E41F134D13C2 c4u34 undef
7323AC1 23DF198
Where are my other nodes show it as "switch":
# nodediscoverls | grep c4u33
0ED7839B-3FC1-DF11-B752-E41F134D42D8 c4u33 switch
7323AC1 23DF167

Odd that rsetboot should take a long time. I assume something like rpower
stat also takes a long time?

Subject: [xcat-user] Upgraded to xCAT 2.8.4, nodeset not working as
expected.
Good morning,
I upgraded xCAT via yum last week from 2.8.3 to to 2.8.4. Since then,
if I put a node (in this case a dx360M3) through discovery, discovery
completes, but if I then try and use nodeset to use toolscenter or set this
diskless image on the node (nodeset XXX osimage=), it isn't working.
I'm noticing that the nodeset and rsetboot commands are taking > 30
seconds to complete and when I reboot the node, it just tries to boot from
disk. A little digging and it appears that nodeset isn't updating the
underlying files on /tftpboot/xcat/xnba/nodes/* like expected:
# /usr/bin/time -p nodeset c4u34 netboot=toolscenter-x86_64-bomc
c4u34: netboot toolscenter-x86_64-bomc
real 31.20
user 0.11
sys 0.03
# cat /tftpboot/xcat/xnba/nodes/c4u34
#!gpxe
#netboot toolscenter-x86_64-bomc
LOCALBOOT 0
# /usr/bin/time -p nodeset c4u34 osimage=rhel6_c-x86_64-netboot-compute
c4u34: netboot rhel6_c-x86_64-compute
real 49.85
user 0.12
sys 0.01
# cat /tftpboot/xcat/xnba/nodes/c4u34
#!gpxe
#netboot rhel6_c-x86_64-compute
LOCALBOOT 0
The long time makes me think it's hitting a timeout value and aborting.
Did I miss something with the upgrade to 2.8.4? I have no problems with
2.8.3 and discovery is working on 2.8.4.
Thanks,
