Summary: Problem with tapedevices and the tarfile module
Initial Comment:
Problem to read a archive from tape that was created
with the tarfile module in python.
Error:
>>> tar = tarfile.open("/dev/st0", "r")
Traceback (most recent call last):
File "", line 1, in ?
File "/usr/local/lib/python2.4/tarfile.py", line
916, in open
return func(name, "r", fileobj)
File "/usr/local/lib/python2.4/tarfile.py", line
933, in taropen
return cls(name, mode, fileobj)
File "/usr/local/lib/python2.4/tarfile.py", line
811, in __init__
fileobj = file(self.name, self.mode)
IOError: [Errno 16] Device or resource
busy: '/dev/st0'
I was creating the archive with succes:
>>> tar.close()
>>> tar = tarfile.open("/dev/st0", "w")
>>> tar.add("/tmp/bin1.tar")
>>> tar.add("/tmp/bin2.tar")
>>> tar.close()
>>>
When I try to read the tape without pyton the
folowing error:
[EMAIL PROTECTED] tmp]# tar tvbf 20 /dev/st0
tar: Record size = 8 blocks
-rw-r--r-- root/root 128614400 2005-11-20 19:53:11
tmp/bin1.tar
tar: /dev/st0: Cannot read: Cannot allocate memory
tar: /dev/st0: Cannot read: Cannot allocate memory
tar: /dev/st0: Cannot read: Cannot allocate memory
tar: /dev/st0: Cannot read: Cannot allocate memory
tar: /dev/st0: Cannot read: Cannot allocate memory
tar: /dev/st0: Cannot read: Cannot allocate memory
tar: /dev/st0: Cannot read: Cannot allocate memory
..
Can anyone help me with this problem or have another
module for tarfile that works with tapedevices?

Could try and use tarfile's stream interface for writing and
reading and see if that works? Just append a pipe symbol to
the mode, e.g.:
tar = tarfile.open("/dev/st0", "w|")
