[nbdkit python]: unable to locate modules
by Bill Speirs 21 May '15

21 May '15

I'm working on a python plugin for nbdkit that treats Google Cloud Storage as a block device. I have a library, gcs.py, that implements simple commands: list, get, put, delete; source is here: https://github.com/wspeirs/cldblkdev/blob/master/gcs.py When I attempt to run nbdkit I get the following error: nbdkit python script=/home/wspeirs/src/cldblkdev/cldblkdev.py Traceback (most recent call last): File "/home/wspeirs/src/cldblkdev/cldblkdev.py", line 5, in <module> import gcs File "/home/wspeirs/src/cldblkdev/gcs.py", line 2, in <module> import httplib2 File "/usr/local/lib/python2.7/dist-packages/httplib2/__init__.py", line 930, in <module> class HTTPSConnectionWithTimeout(httplib.HTTPSConnection): AttributeError: 'module' object has no attribute 'HTTPSConnection' Error in sys.excepthook: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/apport_python_hook.py", line 63, in apport_excepthook from apport.fileutils import likely_packaged, get_recent_crashes File "/usr/lib/python2.7/dist-packages/apport/__init__.py", line 5, in <module> from apport.report import Report File "/usr/lib/python2.7/dist-packages/apport/report.py", line 16, in <module> from xml.parsers.expat import ExpatError File "/usr/lib/python2.7/xml/parsers/expat.py", line 4, in <module> from pyexpat import * ImportError: /usr/lib/python2.7/lib-dynload/pyexpat.x86_64-linux-gnu.so: undefined symbol: _Py_ZeroStruct Original exception was: Traceback (most recent call last): File "/home/wspeirs/src/cldblkdev/cldblkdev.py", line 5, in <module> import gcs File "/home/wspeirs/src/cldblkdev/gcs.py", line 2, in <module> import httplib2 File "/usr/local/lib/python2.7/dist-packages/httplib2/__init__.py", line 930, in <module> class HTTPSConnectionWithTimeout(httplib.HTTPSConnection): AttributeError: 'module' object has no attribute 'HTTPSConnection' nbdkit: error: /home/wspeirs/src/cldblkdev/cldblkdev.py: error running this script Everything seems to work outside of nbdkit. I'm assuming this is some path related issue... any thoughts on how to fix this? Thanks... Bill-

sfdisk: No more Cylinder / Head / Sector support in util-linux 2.26 and later
by Hilko Bengen 17 May '15

17 May '15

Hi, it was brought to my attention that sfdisk has lost the ability to deal with C/H/S addressing as of util-linux 2.26, so the -C ,-H, -S command line parameters are no longer supported. Should there be a compile-time check based on "sfdisk -h" output that would cause daemon/sfdisk.c to be compiled only if something like the following is present? ,---- | Override the detected geometry using: | -C, --cylinders <number> set the number of cylinders to use | -H, --heads <number> set the number of heads to use | -S, --sectors <number> set the number of sectors to use `---- Cheers, -Hilko
