Absolutely agree. I'l love to be able to free up some LUNs that I don't need in the pool any more. Also, concatenation of devices in a zpool would be great for devices that have LUN limits. It also seems like it may be an easy thing to implement. -Aaron On 2/28/09, Thomas Wagner wrote: >> >> p

Hi Steven, I don't have access to my usual resources to test the ACL syntax but I think the root cause is that you don't have execute permission on the "Not Started" directory. Try the chmod syntax again but this time include execute:allow for admin on "Not Sorted" or add it like this: # chmod
