You can use this command (it's an example):
# In a cluster node where the admin account is available.
ceph tell 'osd.*' injectargs '--osd_disk_threads 2'
After, you can check the config in a specific osd. For instance:
ceph daemon osd.5 config show | grep 'osd_disk_threads'
But you must launch this command in the node which hosts the osd.5
daemon.
Furthermore, with "ceph tell osd.\* injectargs ..." it's possible
to set a parameter for all osds from a simple cluster node with just
one command, but I don't know if it's possible to just _get_ (not set)
the value of a parameter of all osds with just one command.
Does a such command exist?
Personally, I don't know a such command and currently, I have to
launch "ceph daemon osd.$id config show" for each osd which is
hosted by the current server where I'm connected and I have to
repeat the commands in the other cluster nodes.
Regards.
