[Linux-cluster] Newbie question: iozone failing sanity check on gfs filesystem

[Alex Gilman]

Greetings!  I have attempted to set up gfs shared storage in a two-node
cluster (2.6.18-8.el5 x86_64) with an AX150SC SAN device.  Everything
seemed to go alright until I tried to run iozone and got the following
message:

Sanity check failed. Do not deploy this filesystem in a production
environment !

There was nothing in /var/log/messages associated with this.  Has anyone
seen this before?

The filesystem was made by
# gfs_mkfs -t my_cluster:gfs1 -p lock_dlm -j 4 -r 1024 /dev/sdb1

I'm not sure what other information would be helpful in diagnosing this.

Thank you in advance,
