Hi,
I am looking for the ideas on how to check if the machine was under
high I/O pressure before it panicked (caused manually by an NMI).
By I/O I mean disks and ZFS stack.
Do you believe ZFS was a key component in the I/O pressure?
I've CC'd zfs-discuss@opensolaris.org on my reply.
If you think there was a lot of I/O happening, you could run:
::walk zio_root | ::zio -r
This should give you an idea of the amount of ZIO going through ZFS.
I would also be curious to look at the state of the pool(s) and the
ZFS memory usage:
::spa -ev
::arc
Kind regards,
Jason
