I thought that jails would be a good candidate for dedup. So far I am using
it without any issues in my /usr/src and /virtualBox directories.
No idea about your problem, but ezjail is already doing
As far as I am aware ezjail has the option to use compression and disable
access time updates.
ezjail_zfs_properties=-o compression=lzjb -o atime=off
In my case the dedup option was turned on only in the basejail causing the
system to temporarily freeze. Once the dedup option was removed
Can you attach the output from zdb -DD zhome ?

How much memory do you have in the system? Any L2ARC devices? Depending
on the amount of memory in your box, it could be that ddt is spilling

The system has 4Gs of RAM. I don''t use any devices for L2ARC and my tuning
is like this:
vm.kmem_size=3072M
vfs.zfs.arc_max=2048M
I had my eyes on the memory during the whole procedure and things looked
normal.
Thanks
