Please run the following commands and paste the console session into a 
reply:

# freebsd-version ; uname -a

# zpool status -v mypool


So, you had 5 drives in RAIDZ1, one died, you removed the failed drive, 
you installed a replacement drive, and you issued a 'zpool replace' command?


Have you disabled services that use datasets in that pool?


Have you set the readonly property on those datasets?


Do you have a backup?
