Description

t:lustre-release# export STRIPE_BYTES=$((1048576 * 4))
t:lustre-release# llmount.sh 
...
t:lustre-release# sleep 60 
t:lustre-release# lctl get_param lov.*.stripesize

t:lustre# lctl get_param lov.*.stripesize
lov.lustre-MDT0000-mdtlov.stripesize=4194304
lov.lustre-clilov-ffff88001c570be0.stripesize=1048576

When we mount the client, we see the following on the console which is misleading and annoying:

[85604.363909] LustreError: 9299:0:(obd_config.c:1392:class_process_proc_param()) lov.: error writing proc entry 'stripesize': rc = -30
