error: pool_new can contain only alphanumeric characters, underscores, and 
dashes besides the required '.'
pool_new: Invalid argument

dmesg logs:

LustreError: 19441:0:(mgs_llog.c:5513:mgs_pool_cmd()) lustre is not defined

Is this an error anyone has seen or knows a solution to?

The problem is that the pool name should be "fsname.pool_name", and your 
filesystem is named "lfs1" and not "lustre".  The
last error message above is trying to say this, but it could be more clear, 
like "filesystem name 'lustre' is not defined" or similar.  A patch to fix this 
would be welcome.

So your command should be:

lctl pool_new lfs1.pool1

though I would suggest a more descriptive name than "pool1" (e.g. "flash" or 
"new_osts" or whatever), but that is really up to you..

Cheers, Andreas
