[Rocks-Discuss] insert-ethers, cabinet & rank, and a bug report
Rob Hutten
Hi all,
A question about running insert-ethers, and a bug report.
I'm adding a node to one of our Rocks 5.1 clusters using this command:
insert-ethers --rank=28 --cabinet=1
The existing nodes are numbered c1-0 to c1-31, but for historical
reasons c1-28 was never brought online until now.
When the node PXIE-boots, insert-ethers crashes with an error, the text of
which is dumped to the screen rendered with unreadable/non-ascii chars.
So I re-ran insert-ethers with stderr redirected to a file; this showed
the message to be:
error - int() argument must be a string or a number
It works just fine without the --rank and --cabinet params, but it names
my node "compute-0-0". "insert-ethers --cabinet=1" (without the --rank)
also produces this error. I've also tried --rack instead of --cabinet,
just for shiggles. Same error.
Is this not the standard way to name a new compute node "compute-1-28"?
I've attached the output of "dbreport bug".
...
And the bug report: Again under Rocks 5.1, insert-ethers was giving
me the aforementioned display grief so I was futzing with different
$TERM settings. As per below, insert-ethers doesn't seem to clean up
its lockfile when it bails:
[root@fog ~]# export TERM=tty
[root@fog ~]# insert-ethers
Unknown terminal: tty
Check the TERM environment variable.
Also make sure that the terminal is defined in the terminfo database.
Alternatively, set the TERMCAP environment variable to the desired
termcap entry.
[root@fog ~]# export TERMCAP=tty
[root@fog ~]# insert-ethers
Traceback (most recent call last):
File "/opt/rocks/sbin/insert-ethers", line 1718, in ?
app.run()
File "/opt/rocks/sbin/insert-ethers", line 1677, in run
raise _("error - lock file %s exists") % self.lockFile
error - lock file /var/lock/insert-ethers exists
[root@fog ~]# ls -ltr /var/lock/insert-ethers
-rw-r--r-- 1 root root 0 Sep 3 16:52 /var/lock/insert-ethers
[root@fog ~]# date
Thu Sep 3 16:53:21 ADT 2009
Ignore that "tty" is invalid - it should still clean up its lockfile.
No-one else was running insert-ethers at the time.
Thanks,
-Rob

# rocks add host compute-1-28 rack=1 rank=28
# rocks set host interface compute-1-28 eth0 ip=10.X.Y.Z
(make all the settings except ip match the output of "rocks list host interface compute-1-27)
# rocks set host interface mac compute-1-28 eth0 00:0a:0b:0c:0d:ff
(the mac should be on a sticker on the nic or mb)
I've probably missed some steps, but if you google the "rocks set host interface" you'll probably find another posting by greg that lists all the steps.

Also, isn't it supposed to be "--rack=1 --rank=28"? Give it a shot...

try:
# rocks sync config
then try:
# insert-ethers --cabinet=1 --rank=28

This worked perfectly. Thanks, Greg!
