Hi,
Thanks for trying it out. Indeed, this option is currently missing from ceph-dokan but it’s an easy thing to add. We’ll take care of it as soon as possible, hopefully it will be included in the Pacific release.
Please let us know if you have any other suggestions.
Regards,
Lucian Petrut
Hi,
We have been testing ceph-dokan, based on the guide here:
<https://documentation.suse.com/ses/7/single-html/ses-windows/index.html#windows-cephfs>
And watching <https://www.youtube.com/watch?v=BWZIwXLcNts&ab_channel=SUSE>
Initial tests on a Windows 10 VM show good write speed - around 600MB/s,
which is faster than our samba server.
What worries us, is using the "root" ceph.client.admin.keyring on a
Windows system, as it gives access to the entire cephfs cluster - which
in our case is 5PB.
I'd really like this to work, as it would let user administrated Windows
systems that control microscopes to save data directly to cephfs, so
that we can process the data on our HPC cluster.
I'd normally use cephx, and make a key that allows access to a directory
off the root.
e.g.
[root@ceph-s1 users]# ceph auth get client.x_lab
exported keyring for client.x_lab
[client.x_lab]
key = xXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX==
caps mds = "allow r path=/users/, allow rw path=/users/x_lab"
caps mon = "allow r"
caps osd = "allow class-read object_prefix rbd_children, allow rw
pool=ec82pool"
The real key works fine on linux, but when we try this key with
ceph-dokan, and specify the ceph directory (x_lab) as a ceph path, there
is no option to specify the user - is this hard-coded as admin?
Have I just missed something? Or is this a missing feature?
anyhow, ceph-dokan looks like it could be quite useful,
thank you Cloudbase :)
best regards,
Jake
