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,
-Brad Viviano
