The patch work well.
 Thanks!

2007/3/23, Nathaniel Rutman <[EMAIL PROTECTED]>:

Well, your question prompted me to try this out.

There are two issues:
1. failout mode cannot be set on a live filesystem, and can't be set
with lctl conf_param.
The wiki page has instructions for setting failout mode at mkfs time
https://mail.clusterfs.com/wikis/lustre/MountConf
You can also set failout mode with tunefs and writeconf:

tunefs.lustre --writeconf --param="failover.mode=failout" /dev/sda

There can be no Lustre servers or clients running when changing the
failover mode.

2. failout mode is broken in the 1.6 betas.  I have an untested patch in
bug 12005
https://bugzilla.lustre.org/show_bug.cgi?id=12005
Using failout mode in the betas without this patch will probably lead to
an LBUG on the OST.
