Description
No big deal but I just noticed that:
lctl conf_param fsname-OST*.obdfilter.brw_size=16
from the Lustre manual, seems broken. It doesn't change the brw_size values, even after remounting the OSTs.
using
echo 16 > /proc/fs/lustre/obdfilter/*${ost}*/brw_size
or
lctl set_param obdfilter.fir-OST*.brw_size=16
just works fine to change the values temporarily. We use tuning.conf from shine which is applied at mount time so it doesn't really affect us but it might affect others. This is with 2.12.0.
