On Opensolaris build 134, upgraded from older versions, I have an rpool for
which I had switch on dedup for a few weeks.
After that I switched to back on.
Now it seems the dedup ratio is stuck at a value of 1.68.
Even when I copy more then 90 GB of data it still remains at 1.68.
Any ideas ?
Paul
Here is some evidence…
Before the copy :
$ zpool list
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
rpool 931G 132G 799G 14% 1.68x ONLINE -
$
After the copy :
$ zpool list
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
rpool 931G 225G 706G 24% 1.68x ONLINE -
$
It has only been enabled for 11 days last month.
$ pfexec zpool history |grep dedup
2010-02-11.21:19:42 zfs set dedup=verify rpool
2010-02-22.21:38:15 zfs set dedup=off rpool
And it is off on all filesystems:
$ zfs get -r dedup rpool
