Dear all,
we are new to xCAT, so please excuse if the questions are somehow
trivial. Actually we have three questions but I will put them into
different mails.
What we try to do:
We run a ~200 node cluster and install one node as golden (not deployed
through xCAT), then use imgcapture to pull it and deploy it onto the
others. We started with a CentOS 6.9 node (moving to CentOS 7 soon,
that's why we need a tool like xCAT now).
First problem occoured is that the partition, the node has:
[root@wnfg002 ~]# sfdisk -uM -l /dev/sda
Disk /dev/sda: 121597 cylinders, 255 heads, 63 sectors/track
Units = mebibytes of 1048576 bytes, blocks of 1024 bytes, counting from 0
Device Boot Start End MiB #blocks Id System
/dev/sda1 * 1 200 200 204800 83 Linux
/dev/sda2 201 48200 48000 49152000 82 Linux swap / Solaris
/dev/sda3 48201 953836 905636 927371264 83 Linux
/dev/sda4 0 - 0 0 0 Empty
[root@wnfg002 ~]#
During capture there was a message from the perl script:
[master]: wnfg002:
wnfg002: This client is ready to have its image retrieved. You must now run
wnfg002: the "si_getimage" command on your imageserver.
wnfg002:
wnfg002: Automatically create configuration file for systemconfigurator:
wnfg002: >> /etc/systemconfig/systemconfig.conf
[master]: Getting osimage "wnfg" from wnfg002 to cmu.
[master]: Argument "*" isn't numeric in numeric lt (<) at
/usr/lib/systemimager/perl/SystemImager/Server.pm line 575, <$TEMPLATE>
line 165.
And the 3rd partition (/dev/sda3) end up to be faulty in the deploy script:
/install/sysclone/scripts/wnfg.master
logmsg "Creating partition ${DISK0}3."
START_MB=$END_OF_LAST_PRIMARY
END_MB=$(echo "scale=3; ($START_MB + 1)" | bc)
(the size should be 905635).
Of course I can patch the script, but maybe someone has an idea why the
size got determined wrongly (too large?)
xCAT version is 2.14.5
Kind regards,
Torsten
