Very weird. It definitely looks like a twisted 8.1 issue, but I can't
reproduce it.
I've installed a fresh etch machine, dist-upgraded to lenny and
installed ganeti-1.2.6-2, and it works (I can't install 1.2.3 from
backports before dist-upgrade since they removed it).
Attached to this mail is a python script; can you run it from any node
as: "python call_version.py $node"
where $node should be any of your ganeti nodes. For me it looks like:
# python call_version.py localhost
[twisted, version 8.1.0]
Call 0, result: 14
Call 1, result: 14
Call 2, result: 14
Call 3, result: 14
Call 4, result: 14
Call 5, result: 14
Call 6, result: 14
Call 7, result: 14
Call 8, result: 14
Call 9, result: 14
If twisted interation is indeed broken, it will hang before printing
"Call 1". You can also test against more than one node, maybe the
problem is only with a subset of the nodes... Although the fix in 1.2.5
was for the client side, not the server side.
Also, "dpkg -l" would be welcome so that I can install exactly the same
package list.
iustin
#!/usr/bin/python -ut
import sys
import twisted
from ganeti import rpc
print twisted.version
node = sys.argv[1]
for i in range(10):
result = rpc.call_version([node])
print "Call %d, result: %s" % (i, result[node])
