[lustre-discuss] set_param permanent on client side ?

[Riccardo Veraldi]

Hello,

how do I set_param in a persistent way on the lsutre clinet side so that
it has not to be set every time after reboot ?

Not all of these parameters can be set on the MDS, for example the osc.* :

lctl set_param osc.*.checksums=0
lctl set_param timeout=600
lctl set_param at_min=250
lctl set_param at_max=600
lctl set_param ldlm.namespaces.*.lru_size=2000
lctl set_param osc.*.max_rpcs_in_flight=64
lctl set_param osc.*.max_dirty_mb=1024
lctl set_param llite.*.max_read_ahead_mb=1024
lctl set_param llite.*.max_cached_mb=81920
lctl set_param llite.*.max_read_ahead_per_file_mb=1024
lctl set_param subsystem_debug=0

thank you
