Hello, I am running into an issue when attempting to setup pooling.

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..
