Hi,
I'm testing targetcli-fb on my Archlinux box and restore functionality
is failing with following:
# /usr/bin/targetctl restore
OSError: [Errno 22] Invalid argument
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/lib/python3.4/site-packages/rtslib/node.py", line 140, in
set_attribute
fwrite(path, "%s" % str(value))
File "/usr/lib/python3.4/site-packages/rtslib/utils.py", line 67, in
fwrite
file_fd.write(str(string))

TypeError: 'OSError' object is not subscriptable
I debugged it to following file and value:
# echo 0 >
/sys/kernel/config/target/core/iblock_0/windows_data/attrib/pi_prot_type
bash: echo: write error: Invalid argument
Dmesg logs following:
[168897.460098] DIF protection not supported by backend: iblock
Is it kernel or targetcli-fb issue?
targetcli-fb 2.1.fb35-1
python-rtslib-fb 2.1.fb47-1
python-configshell-fb 1.1.fb13-1
linux 3.14-4
