Ceph » CephFS

• Should /CephFS be assumed as the mount point on the host system at which the cephfs is mounted ?
• What was the UID of the user running the setfacl command ?

The paths given where for illustration only. Exact paths are something closer to:

/CephFS/Pool-ErasurePool/MediaStore/UserName

And so the error are closer to:

setfacl: /CephFS/Pool-ErasurePool/MediaStore/UserName/Documents: Operation not supported

The user executing the command is root (so 0).

I asked on Discord, and at least one user WAS able to execute the command on their system, so it may be something unique to my environment.

This is a cephadm deployment of 17.2.5 on Ubuntu 20.04.5 LTS.

With the root mount point being /CephFS.

I do have several folders with specific EC and replication pools (hence Pool-ErasurePool in the path).

Not sure if that is relevant, but stating it just in case.

Brian,
Could you share the MDS debug logs for this specific operation.
It'll help us identify the failure point.

Just raise the mds debug level to 20 before the setfacl and drop it to the required level after the command finishes.

So, I am having a hard time trying to set that... Missing something simple.

I see these in the GUI:

mds_debug_auth_pins
mds_debug_frag
mds_debug_scatterstat
mds_debug_subtrees

And attempting to get the config from CLI I get this:

# ceph daemon mds.### config show | grep debug | grep level
    "debug_leveldb": "4/5",
    "mon_cluster_log_file_level": "debug",

And both of these:

ceph daemon mds.### config set mds_debug_level "20" 
ceph daemon mds.### config set mds_debug "20" 

Result in:

ERROR: (2) No such file or directory
error getting 'mds_debug': (2) No such file or directory

What am I missing... :(

Brian,
The command you are using is correct.
However, the config key is incorrect.
Set debug_mds to 20 for all mds daemons.

FYI - https://docs.ceph.com/en/latest/rados/troubleshooting/log-and-debug/
Check the section "SUBSYSTEM, LOG AND DEBUG SETTINGS" for the different ceph subsystems that you can request logs for.

Brian,
Have you read up these docs about turning on ACLs ?
