[lustre-discuss] lctl set_param obdfilter.*.readcache_max_filesize=2M fails

[Pinkesh Valdria]

Hello Lustre experts,

 

I am fairly new to lustre and I did a deployment of it on Oracle Public Cloud using instructions on whamcloud wiki pages.    I am now trying to set some parameters for better performance and need help to understand why I am getting this error: 

 

On OSS Servers:  

[root at lustre-oss-server-nic0-1 ~]# lctl set_param obdfilter.*.readcache_max_filesize=2M

error: set_param: param_path 'obdfilter/*/readcache_max_filesize': No such file or directory

[root at lustre-oss-server-nic0-1 ~]#

 

 

Also I have seen this happen on Client nodes:

lctl set_param ldlm_timeout=200  - This fails with below error 

error: set_param: param_path 'ldlm_timeout': No such file or directory

 

 

Appreciate your help.
