Hi David,

Thanks very much for your clear explanation of how to snapshot XFS
filesystems with external log. It is good to know that I am doing it
right.

I found that in the latest Linux kernel version 2.6.22.1, you cannot use
the method I have been using, and which you confirmed is ok. The problem
is that if you xfs_freeze the filesystem, then the LVM snapshot command
hangs forever. (Back in kernel version 2.6.16 this did not happen.) I
guess the snapshot command is also attempting to freeze the filesystem,
or something, which doesn't work when it is already frozen. I suppose
how to fix this is a question for the linux-lvm mailing list.

Thanks again for your detailed answer.
