Hello.

I tried to create user:glfs backstore, but failed with this message.

After that, I reinstall python-rtslib and targetcli (use old version. rtslib - 2.1.fb63-5, targetcli - 2.1.fb46-1),

and I could make user:glfs backstore.

Here is the version information of targetcli and python-rtslib

Fail - targetcli 2.1.fb46-4, python-rtslib 2.1.fb63-11

Success - targetcli - 2.1.fb46-1, rtslib - 2.1.fb63-5

@pkalever you fixed this in rtslib-fb master branch right?

@parkch0708 It might be this patch

https://github.com/open-iscsi/rtslib-fb/commit/eff378068812503ee2394baffba37b5cadd9a0f7

Also, I think the preferred glfs management tool is the gluster block tool. It will not help on this bug, but I think in general it might be easier to use.
