How long it takes to finish a 'nodeset <node> osimage> command? From the syslog, did you see all the nodes get hanging in nextdestiny for a while before getting into deployment process (10 minutes?)? Or you saw the nodes got into deployment process one by one with a fixed interval (what was the interval?).
Thanks
Best Regards

There is just 2 tasks, a runimage and an osimage.
chain.currchain=osimage, and chain.currstate=runimage=
http://master/install/script.tgz.
The image is available to be downloaded. A nodeset on a single node
completed immediately.

How many tasks in your chain list?
What's the value of chain.currchain and chain.currstate for nodes
when you saw that a lot of processes hang in 'nextdestiny' request?
What I can think of is the 'nextdestiny' will try to check the http
download path of 'runimage', could you check the path is accessible
from xCAT MN? And could you run 'nodeset <node> runimage=xxx' to see
how much time it takes to finish?
Thanks

nextdestiny
Hi all,
My management node is experiencing a spike of over 60 load when I
boot
70 nodes at once and request a runimage of them. Doing a "ps aux"
shows
high iowait and what appears to be a perl process for nextdestiny
running for each node. We had this same issue under xCAT 2.3, and was
under the hopeful impression that performance was increased with xCAT
2.8 and nextdestiny behavior.
After about 10 minutes it seemed to have chewed through the requests
and
the nodes continued their respective chained commands. Is there a way
of
improving the way the management node handles nextdestiny requests
from
10's of nodes at once?
Thanks!
