>Description:
I just attached an unused ZFS (version 14) disk to another (version 13) to form
a mirror, supposedly destroying the old disk. However, zpool resilver went
bidirectionally, and reported incorrect time both during and after completion:
$ zpool status
pool: mypool
state: ONLINE
scrub: resilver completed after 307445734561825858h7m with 0 errors on Sun Jul
11 05:44:51 2010
config:
NAME STATE READ WRITE CKSUM
mypool ONLINE 0 0 0
mirror ONLINE 0 0 0
ad4 ONLINE 0 0 0 528M resilvered
ad6 ONLINE 0 0 0 1.11T resilvered
errors: No known data errors
$
1. Resilver time should not be 307445734561825858h7m
2. zpool resilver should be unidirectional (from "master" to "slave"), why did
it resilvered both ways (528M and 1.11T)?
