Hi zhouxl,

If you are having journal issues, you need to contact Isilon Support immediately as you may be at risk for data loss.

Live chat is available here:

Otherwise you can create a service request here:

Blown journals are very, very bad.  You will need to contact support and will go through a detailed flowchart on what actions to take.  They will likely declare a "code red" when escalating the issue internally.  This is serious.
