You said you had more than one volume ?. Were the disks all added at the same time ?. That is, you have not added a disk to an existing volume?. Is the activity read or write activity or a mix ?. Can you post up a sysstat output ?. Try using 'statit' which will indicate if a specific disk is being hammered. If this is the case then it would mean that a disk was added to the volume group after vol creation and normal stripping is not in effect.

Pawel, Are your file systems becoming full (type "df" from netapp")? Mike

Mine are at 50% in terms of disk space used.

1 volume, 12 disks, 18GB, F760, gige to client systems.

I show 91-94% cache hit rate, but disk utilization is 98-100% during the business day.
