Comment 27 for bug 1921658

@ddstreet

yep I've checked that ( [:1] or something else )

This issue is only happening when back storage is LVM.

If it is not lvm, it is ok, only with lvm, pexepct returns weird string

2021-03-17 20:43:34 stderr: [error] Arguments: ([' ', '<3ef-46ca-87c8-19171950592f --pool maas_guest_lvm_vg', "error: command 'attach-disk' doesn't support option --pool"],)

I've checked MAAS code first at the time, but pexpect related code showed me the same result everywhere.

So I suspected that it is underlying issue. and compared libraries in maas snap, then I found out libreadline patch attached in this LP. ( as libradline is related to running command )

But I still can't find original libreadline reproducer or link between maas and libreadline yet.

I've asked this to libreadline's maintainer ( this patch's auther) but he also doesn't know, and the mentioned that this could be a side effect of patch.

Thanks
