how can I spot actual hash collisions in dedup?
Posted: Mon Apr 26, 2021 1:59 amHi you all,
I've been using ZFS on Mac since 2008 (yeah, time flies...) and I'd like to say
thank you to all the devs of OpenZFS on OS X who have kept things alive and
moving forward! 2.0 in particular looks like a great step change!
Now my question: I have a large pool with dedup=skein,verify that I'd like to
move to a new location. Is there a way for me using zdb, kstat.zfs, or whatever
to see if I do have any hash collisions in my pool? Because ... transferring without
the ,verify part would save me a few days time, but I'd want to be sure.
Thanks in advance for any advice or pointers,
Germano
