Hi all,
I want to use cephfs-shell dealing with operations like directory creation,
instead of mounting the root directory and create manually. But I get
errors
when I execute the command 'cephfs-shell'.
Traceback (most recent call last):
File "./cephfs-shell", line 9, in <module>
import cephfs as libcephfs
ModuleNotFoundError: No module named 'cephfs'
CentOS7 use python2 and I've already installed python3 in the system.
What else should I do, reinstall libcephfs?
Thanks

This error disappeared after I installed 'python3-cephfs'. However the
cephfs-shell command stuck.
It stays at 'CephFS:~/>>>' and whatever subcommand I executed, it
printed
an error as below:
EXCEPTION of type 'TypeError' occurred with message: 'onecmd() got an
unexpected keyword argument 'add_to_history''
How can I use 'cephfs-shell'?

What's the cmd2 version on your system? Looks like you are having an
issue with it.
Although most of the recent cmd2 versions are supported too, 0.7.9 is
more recommended IMHO since cephfs-shell is regularly tested against
it. You can install it via pip if you can't find it in CentOS7's
repositories.
Also, please let me know the Ceph version you are using so that I can
try to reproduce the issue next time.

What's more, I tried in CentOS 7 as well as 8, and I got the same error.

Hi Rishabh,
I installed cmd2 with pip, followed by document
<https://docs.ceph.com/docs/master/cephfs/cephfs-shell/>.
As you recommended, I set the install version of cmd2 to 0.7.9, and
cephfs-shell is good to go.
Thanks a lot :)

When I use cephfs-shell, I find that some commands are useless.
And I am forced to use the interactive mode.
I'm not sure if I use it in the correct way or not. Is there a more clear
document?

That's odd, either the command should be absent or should run
successfully. On inspecting the source code, listxattr command is
actually absent in Nautilus; it's available Octopus onwards.
And I am forced to use the interactive mode.
Yes, that is one issue with cephfs-shell that got fixed recently. The
fix is clearly not backported to Nautilus (that is Ceph version 14)
from the output you attached in your email.

AFAIK no. But I would like to point out that the doc you are referring
(https://docs.ceph.com/docs/master/cephfs/cephfs-shell/) is for latest
version of cephfs-shell, Nautilus has lesser features (for example,
listxattr command is present in master but absent in Nautilus)

That's my mistake, I should have read the document of Nautilus.
It's OK for the failed commands. 'mkdir' is enough for me at present.
Thanks Rishabh, I will try it on Octopus cluster.
