Pawel, Are your file systems becoming full (type "df" from netapp")? Mike
-----Original Message----- From: Pawel Rogocz [mailto:pawel@rogocz.com] Sent: Thursday, October 31, 2002 1:24 PM To: toasters@mathworks.com Subject: My F820 is slow ....
I run 6.2.1 on F820 and I have bunch of Sun boxes ( around 60 ) who do NFS mounts.
The filer has more than one volume and sometimes during the day the output of systat -x shows 100% disk util for a couple of minutes.
1. Is there a way to find out which volume/disk is causing bottleneck ? 2. Is there a way to find which client is causing the load to spike ? 3. Can disk util be monitored via SNMP ? I was not able to find anything in the MIB provided on NOW.
thanks,

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.
Here it is:
/vol/vol1/ 338309500 292869428 45440072 87% /vol/vol1/ /vol/vol1/.snapshot 37589944 16548736 21041208 44% /vol/vol1/.snapshot /vol/vol2/ 338309500 303317696 34991804 90% /vol/vol2/ /vol/vol2/.snapshot 37589944 13034816 24555128 35% /vol/vol2/.snapshot /vol/vol0/ 50119928 1674084 48445844 3% /vol/vol0/ /vol/vol0/.snapshot 12529980 142548 12387432 1% /vol/vol0/.snapshot /vol/vol3/ 112769836 63064324 49705512 56% /vol/vol3/ /vol/vol3/.snapshot 12529980 20120056 0 161% /vol/vol3/.snapshot /vol/vol4/ 338309500 269767512 68541988 80% /vol/vol4/ /vol/vol4/.snapshot 37589944 13586164 24003780 36% /vol/vol4/.snapshot
