IOError: [Errno 28] No space left on device

[hong zhang]

List,

My python script has a strange error.

cont_tx = 1
for i in glob.glob('/sys/kernel/debug/ieee80211/phy*/iwlagn/data/continuous_tx'):
with open(i, 'w') as f:
print >>f, cont_tx

work perfectly.

But following get error like:
print >>f, cont_tx
IOError: [Errno 28] No space left on device

def do_cont_tx( is_start):
global cont_tx_started, stdscr
if is_start == START and not cont_tx_started:
cont_tx = 1
for i in glob.glob('/sys/kernel/debug/ieee80211/phy*/iwlagn/data/continuous_tx'):
with open(i, 'w') as f:
print >>f, cont_tx

Too many layers?
Thanks for help.

Apparently the harddisk where you stored the file is full?

Likely a misinterpretation of the error. I'm guessing either one
needs to be root to write to this [likely virtual] file, or a
member of an associated group. It would help to have the output of

bash$ whoami
bash$ id

and

bash$ ls -lsF
/sys/kernel/debug/ieee80211/phy*/iwlagn/data/continuous_tx


I'd be particularly interested in the group association and the
permission bits.
