So, why is a resilver in progress when I asked for a scrub?

[zfs-discuss] zpool scrub started resilver, not scrub (DTL non-empty?)

All Rights Reserved. > Use is subject to license terms. > Assembled 04 May 2009 > > How do I scrub this pool?>From http://black-chair.livejournal.com/21419.htmlzpool scrub *should* work just fine. The only time a scrub will turn into a resilver is when there are disks whose DTL (dirty time log -- the thing that keeps track of which transactions groups need to be resilvered on which disks) is non-empty. The idea is that if a resilver is necessary, than it''s higher priority than a scrub. Can you tell me a little more about your setup? Just drop me a personal e-mail -- Jeff Bonwick, first.last at sun.com. So, how do I find out if the DTL is non-empty? Looks like it is nevery non-empty. And, if it is non-empty, how do I make it empty? -- albert chin (china at thewrittenword.com)
