xfs_repair doesn't keep a separate log file. All the output is on the command
line. You'll need to either redirect the output of stdout and stderr to a
file, or keep a screen or console log.

The contents of /var/log/messages could help you to understand why xfs might
have forced shutdown, but won't help you with xfs_repair.
Since you're getting IO errors, it sounds like you have a problem lower in the
stack than the filesystem. At the filesystem level there isn't much we can do
with a block device that is giving IO errors so we just shut down. Consider
copying the remote block device to a local one ('dd' might be a good choice for
this) and see if you can get a clean copy. Then it's time to see about the
filesystem.

Ben
