Modified "zpool" for Solaris 11 11/11 and Solaris 10 8/11 (s10u10)

For your convenience, I have prepared patched versions (with an "ashift" setting of 12) of the original zpool program for Solaris 11 11/11 and Solaris 10 8/11 (s10u10).

It has been produced by binary patching, following the idea presented here and here.

Hi, can you advise how to build a patched zpool binary for Solaris 11.1 ? I tried zpool-s11-1111 with Solaris 11.1 but it gave me "property 'ashift' is not a valid pool property". Now I'm trying to obtain installation iso of Solaris 11 11/11 but no luck so far..

Thanks!

I installed 11.1 for the first time a few days ago. Will try to reproduce your problem and eventually provide a patched version of the 11.1 zpool binary. Stay tuned.

I was just able to create a zpool with ashift=12 using zpool_s11_1111 on Solaris 11.1.

Seems to work.

Cool, thanks!

I found out I was using wrong syntax while creating zpool. I tried ZFS on Linux earlier and there is possible to specify "ashift" while creating pool. Obviously this is not the case with Solaris... :-)

Hi!, can this binary be used only to create the pool?, or it must be used for all the future operations on it?

You only need to use the patched zpool binary to create the pool. Later you can use the unmodified version.

Just found your blog, and acording to 4k block size problem i found other solution.

My configuration is Sun Fire T2000 where i install WD Scorpio black 750GB (WD7500BPKT) They have physycaly 4k blocks but report to system 512b.

Thats solution for me:

$ tail -2 /kernel/drv/sd.conf
sd-config-list =
"ATA WDC WD7500BPKT", "physical-block-size:4096";

And after reboot:

$ ./blocksize /dev/rdsk/c0t2d0
dkmp.dki_capacity = 1465149168
dkmp.dki_lbsize = 512
dkmp_ext.dki_capacity = 1465149168
dkmp_ext.dki_lbsize = 512
dkmp_ext.dki_pbsize = 4096

$ zdb -C black | grep ashift
ashift: 12

.. benchmarking in progress now
