i got an error when use gwcli to create a rbd image about ceph-iscsi HOT 9 OPEN

Initial guess is that your version of rtslib-fb is too old.

from ceph-iscsi.

... specifically it's missing this commit: open-iscsi/rtslib-fb@9637223#diff-994836a456b8ff8e93d461b0e27b9adf

from ceph-iscsi.

my rtslib-fb version is 2.1.fb69
i cat the tcm.py
it patch that commit which you point

what others can i do ?

from ceph-iscsi.

Can you attach the /var/log/rbd-target-api/rbd-target-api.log output for the node that hit the problem. In your example above it would be node1's rbd-target-api.log.

from ceph-iscsi.

yes ，i get ther error log when i create the image , in fact ,it create success,but it can't add to lun.

That log output seems to confirm we are still missing that patch:

open-iscsi/rtslib-fb@9637223#diff-994836a456b8ff8e93d461b0e27b9adf

referenced before.

Are you sure the rtslib with that patch is installed correctly? There is not some weird thing where you have multiple versions installed (maybe one in /usr/lib/python2.7/site-packages and one in /usr/lib/python3.6/site-packages) and are looking/using the wrong one?

Did you install rtslib using rpm one time but then used the upstream GH code another time and did not remove the rpm installed package?

Did you manually try to patch the code in /usr/lib/python*/site-packages and maybe did not remove the old tcm.pyc/tcm.pyo file so the old code is still being used?

from ceph-iscsi.

Do you have a

/usr/lib/python*/site-packages/rtslib-fb directory but then also have a /usr/lib/python*/site-packages/rtslib-fb-2.1.fb69.egg or multiple rtslib .egg files?

from ceph-iscsi.

yes , i hava /usr/lib/python2.7/site-packages/rtslib and rtslib_fb and rtslib_fb-2.1.fb69-py2.7.egg
Is some thing wrong with tihs ?

from ceph-iscsi.

Maybe. Did you install rtslib with rpm one time then install it by source using the "python setup.py install" command? The older one might be what is getting used so even if you are seeing a updated/patched tcm.py a older tcmy.py will be getting used.
