Well you cant exceed you max subsciption (105% currently). So if you try to bind a tdev and pool is already hitting the subscription of 105% then the bind operation will fail. You can however increase the subscription % to some higher value (it requires a lot of monitoring as it could lead to pool full situation). If you are far below your max sub limit then yes you can bind the tdevs.  regards,Saurabh
Hi,I'm wondering if I can violate the oversubscription rule on thin pool. For example: I have a thin pool with 105% of subscription, this pool is included in a tier. After some movements, I can see free space on pool (some extends will be promoted/demoted). Could I create other thin devices on  this pool, utilizing the new free space available? The sum of all thin dev (the new one and the already fast migrated) exeeds 105%, but the free space is enough.Mario
