The automatic re-thinning with HIT will require that you convert the volume to thin.  You can convert the standard on the fly without any disruption of service to users. Yes, trust the OS reported size for the actual usage. -joe
Hi, My Equalogic box is complaining about free space. 94% used. which leaves about 300Gb according to SAN HQ, but when I look at my cluster config on sever, its telling me that I have 1.3Tb free.  I just wanted to check my understanding of this.. although my san is saying that its running low on space, I do infact have the 1Tb free that is being reported in windows. down to the fact that the SAN is a block device & although I move/delete from it, it does not then reclaim white space & if I add new files/vhds the white space gets overwritten by the new files, So I do in all likely hood do have the 1TB i am seeing/expecting  thanks
