Client Configuration
|
|
====================

|
|
Updating Client Configuration
|
|
-----------------------------
|
|
|
|
Certain client configurations can be applied at runtime. To check if a configuration option can be applied (taken into affect by a client) at runtime, use the `config help` command::
|
|
|
|
ceph config help debug_client
|
|
debug_client - Debug level for client
|
|
(str, advanced) Default: 0/5
|
|
Can update at runtime: true
|
|
|
|
The value takes the form 'N' or 'N/M' where N and M are values between 0 and 99. N is the debug level to log (all values below this are included), and M is the level to gather and buffer in memory. In the event of a crash, the most recent items <= M are dumped to the log file.
|
|
|
|
`config help` tells if a given configuration can be applied at runtime along with the defaults and a description of the configuration option.
|
|
|
|
To update a configuration option at runtime, use the `config set` command::
|
|
|
|
ceph config set client debug_client 20/20
|
|
|
|
Note that this changes a given configuration for all clients.
|
|
|
|
To check configured options use the `config get` command::
|
|
|
|
ceph config get client
|
|
WHO MASK LEVEL OPTION VALUE RO
|
|
client advanced debug_client 20/20
|
|
global advanced osd_pool_default_min_size 1
|
|
global advanced osd_pool_default_size 3
|
