Hi,

jim owens wrote:

In addition to the user controllable timeout mechanism,
we internally implement AUTO-THAW in the filesystem
whenever necessary to prevent a kernel hang/crash.

If an AUTO-THAW occurs, we post to the log and an
event manager so the user knows the snapshot is bad.


I am interested in AUTO-THAW.
What is the difference between the timeout and AUTO-THAW?
When the kernel detects a deadlock, does it occur to solve it?

Cheers, Takashi
