Thanks- I have the .smb pool, and the container is picking up the config.
After fixing a few errors in my config.json, (I had an underscore between vfs and objects) I am connecting to the smb server, but not able to get to the share, I am not sure if I have something misconfigured with permissions or the share configuration.
My share looks like:
},
"shares": {
"ceph": {
"options": {
"path": "/non-mounted/cephfs/home/",
"kernel share modes": "no",
"vfs objects": "ceph",
"valid users": "rob"
}
}
},
- The Filesystem is home - I tried a few different variations of the path : /non-mounted/home/ /non-mounted/cephfs,...
I made sure the user has access to the file system as well.
But I keep getting this error:
print_impersonation_info: Impersonated user: uid=(1000,1000), gid=(0,1000), cwd=[/]
setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0

Thanks,
Rob

Ah, I was writing my reply from memory and forgot that to create a pool like that you need an extra option:
ceph osd pool create .smb --yes-i-really-mean-it
That said...

Yes it should work OK with a different pool name.

Currently, the system doesn't support kernel mounted cephfs. It only uses the Samba vfs plugin `vfs_ceph` or `vfs_ceph_new` [1] [2] . These do not require mount points to work. Eventually, I'd like to add it as an option but it has not been a priority for us so far.

today!)
