[Lustre-discuss] OST Pools

[John White]

Hello Folks,
	So we're planning on upgrading to 1.8 to take advantage of OST  
Pools.  Namely, we have an existing filesystem running off DDN 9900s  
and are getting some new arrays of a different (known slower)  
hardware.  The aim is to create an (almost) institutional file system  
where new groups can just purchase OSTs and go.  So from what  
documentation I can find, the process for this would appear to be:
-create OSTs as you normally would
-create a new OST pool (lctl pool_new [fsname].[newpoolneame]
-add new OSTs to new OST Pool (lctl pool_add [fsname].[newpoolname]  
[newostuids]
-create a new directory within the existing file system to associate  
with new pool (lfs setstripe [newdirectory] -p [newpoolname]

and... that should be all, right?.. As long as I'm careful with the  
writeconf command going forward, I should be fairly safe with the  
newfangled pool stuff?
