Please describe your problem:
adds per-instance storage capacity.
I had previously read
https://documentation.ubuntu.com/lxd/en/latest/howto/storage_volumes/
https://documentation.ubuntu.com/lxd/en/latest/howto/storage_pools/#resize-a-storage-pool

and tried to run code below

lxc storage set <pool_name> size=<new_size>

but the result is

$ lxc storage set data size=100
Error: Config key "size" is cluster member specific

I've also been searching google and github issues all day for something similar, but it's not working for me.
Did I do something wrong?

sorry for my bad english

What were you expecting?:
I want the storage for a running session to be 50GB or more.
the storage on my server is 256GB free, and 4 cores 8gb memory just to run one device.
