SV: statit figures normal?

Hi,

yes, your statit figures look normal for that kind of configuration.

That's the way WAFL works, it writes across the entire volume, equal amonts of data to each disk. If you mix drivesizes in a volume you will get this kind of behaviour, the smaller disks get filled first so writes go only to the bigger disks. (in your case the limit is roughly 67% of the volume).

Hi,

we've two F740 on one of them there is a volume consisting of 14x18GB disks + 14x36GB disks and it is %70 full we're using it to store our mail files, after peak hour only an additional script is running to delete mailboxes which are not used no more.

here is the statit and sysconfig -r output LOOK FOR THE UTILIZATION of 18GB disks !!!
