Yes, I already read some articles about fletcher checksums and related.

Thanks.

Not necessarily. But it does work as a checksum much better. See

Well, after updating to fresh system scrub finished without errors, and now
rsync is running, now copied 15G out of 150.


You may want to switch the checksum algorithm to fletcher4. It  
(fletcher4 the default instead of fletcher2) is one of the few changes  
between 8-stable and 7-stable in ZFS, which I didn't merge.


Bye,
Alexander.

Well, after updating to fresh system scrub finished without errors, and now 
rsync is running, now copied 15G out of 150.

Do you have recent 7-STABLE? Not sure if it was the same before MFC,
probably not, because what you see is impossible in case of source I'm
looking at. At the begining of zfs_fuid_create() function there is a
check:

if (!zfsvfs->z_use_fuids || !IS_EPHEMERAL(id) || fuid_idx != 0)
return (id);

And IS_EPHEMERAL() is defined as follows:

#define IS_EPHEMERAL(x) (0)

So it will always return here.
