This is also handy if there's going to be a delay between "noticed the drive is dying" and "have a replacement drive available". If the drive is completely dead, then most likely it will be dropped from the pool automatically by ZFS, so "zpool offline" isn't needed. While it's generally "better" to offline drives, ZFS is designed to withstand drives dropping off without warning. > Is there a dedicated mailing list for ZFS user questions? > There's a zfs-discuss mailing list run by the OpenZFS project. There isn't a FreeBSD ZFS-specific mailing list, but there is a freebsd-fs@ mailing list for everything filesystem related (UFS, ZFS, mfs, NFS, etc). Cheers, Freddie
