One can see from the sar -d reports that md1 is at 100% used.
But how to determine which filesystem using the disk devices? Thanks.

Try "iostat -xnpCm 2 " and see if it helps.

Thanks

Thanks for reply. using iostat -xnpCm2 displays filesystems associated
to the root disk group and not the veritas disk gps
like below. Any other ways? Thanks

Must be missing something here...

Can't you just see what filesystems are mounted from df -k, the metadevices
should be listed?

Cheers,
Matt

If you are looking information regarding Veritas disks and volumes, then
vxstat is the command you want to use.

Kind Regards,

Do a "metastat" and see which concat/stripe devices are associated with
which mirrors. Quite frankly, nothing you provided gives that
information. You are not using Veritas Volume Manager here, you are
using SVM/SDS. And if you do an iostat at 5 second intervals, you will
probably see that the 100 percent value is being traded between the
concat/stripe devices in the mirror. "metastat" will tell you how
everything is laid out.

Great success.
