https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256582 --- Comment #12 from Alan Somers <asomers@FreeBSD.org> --- I see the problem. You originally built the pool with ashift=9. But you're trying to replace a disk with ashift=12. If the new disk is actually 512n, then you can still use it by setting vfs.zfs.min_auto_ashift=9. But if the new disk is 512e, then don't do that or your performance will suck. Were the old disks 512n or 512e? You can tell by doing "geom disk list ada0" and look at the Stripesize field. -- You are receiving this mail because: You are the assignee for the bug.
