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. swin wang wrote: > In our test, we didn't set the failout mode in mkfs, but set it on the > mdt/mgs > with lctl: > lctl conf_param testfs-OST0001.failover.mode=failout > but it seem didn't work. when OST0001 is failed, the > client operation is still blocked (with 1.5.97). >
