A few questions on data replication: Assuming I've created a pool named zfspool containing two unmirrored disks and I create:
zfs create zfspool/test2 zfs set copies=2 zfspool/test2 Will data copied in there be guaranteed to be replicated on both devices? Or does ZFS just try its best to spread the data among different devices? Also: Data replication begins on newly-written data AFTER the set copies=? command. Is there a way to force a file system to "catch up" to the new replication settings? (ie: copies=1 switching to copies=2 for ALL data in the filesystem), or is the way to do it to create a new file system with copies=2 and move data to it? Also conversely, copies=2 switching to copies=1, in order to recover disk space...
