Only using 'lctl set_param -P' commands have this issue. Use 'lctl set_param" without "-P" can work fine.
Does it mean params llog full? How can I clear it ?

I have clear the MGS/CONFIG/param then it work fine now.
The param file seems has 128M size limited.

[Emoly Liu]

[sebg-crd-pm (Inactive)]

yes, this ticket can be closed.
