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

[Chris Horn]

You have a typo in the command you ran. Shaun wrote
> lctl set_param osd-*.readcache_max_filesize=2M

but you have:
> lctl set_param ost-*.readcache_max_filesize=2M
ost->osd

> Is  there commands to see all the currently parameters using some get command

lctl list_param -R *

# lctl list_param -R * | grep readcache_max_filesize
osd-ldiskfs.snx11922-OST0002.readcache_max_filesize
osd-ldiskfs.snx11922-OST0003.readcache_max_filesize

That also fails

[root at lustre-oss-server-nic0-1 ~]#  lctl set_param ost-*.readcache_max_filesize=2M
error: set_param: param_path 'ost-*/readcache_max_filesize': No such file or directory
[root at lustre-oss-server-nic0-1 ~]#

Is  there commands to see all the currently parameters using some get command

I think the parameter has changed:
'obdfilter.*.readcache_max_filesize’ => 'osd-*.readcache_max_filesize'

So try:
 lctl set_param osd-*.readcache_max_filesize=2M
