Scott Merrillees,
Thank you very much for the information! I have not figured out what additional info I can get from pvs but between df, ls and the fact that the digits following dev are major and minor numbers of the device, I can find what I needed.
Appreciate your help.
Regards
Reza
===========================================
Try the following commands:
df -h
sudo pvs -o +lv_name
ls -lL /dev/mapper /dev/sd*
which will allow you to map:
dev253-17 to /dev/mapper/vg-lv with device number 253, 17
dev8-0 to /dev/sda with device number 8, 0
then you can map these back up thru the lvm data provided by pvs,
and then up to file systems from df

Hi All,I am a DBA trying to determine if I/O is a bottleneck for an Oracle 11g database running on RHEL 5.7 x64 on VmWare ESXi 4.1. I monitor disk activity using "sar -d" and get device names like dev8-0 and dev253-17. I have tried to translate these device names to filesystem names without succes. Can someone provide instructions on how to find filesystem build on a device name from "sar -d"? Are there any giudeline or better commands for determining if I/O is a bottleneck?Appreciate any help.Regards,Reza
