Hi everyone! I did a huge mistake by upgrading my zpool from build 118 to 122. I didn''t know about the checksum error. The strange thing here is that I don''t get any error at all. My zpool is working very slowly, everything work fine beside the speed. It goes between 900 kb/s to 2 MB/s and accessing files/folders takes very long time. If I start a scrub it takes over 10000 hours even after 3 hours it still grows. My zpool consist of 6 hard-drive with 2 TB disc using raidz2. I have export/import my zpool. everything goes fine. My problem here is the speed. I can''t rollback because i also upgraded my zpool from version 14 to 16 :( now i cant go back to older builds. :( Please help me. I really need help. I did a stupid thing i know. -- This message posted from opensolaris.org

Do you thing that this is a bug? If it is a bug, its okay for me. I can wait for future releases. But if this is happening only for me, then I really need help to solve this problem. -- This message posted from opensolaris.org
You shouldn''t hit the Raid-Z issue because it only happens with an odd number of disks. -- This message posted from opensolaris.org
oh okay! But I still don''t understand why is my zpool acting like this? What kind of error could this be then? I can read/write to the pool but it''s going extremely slow. All my disc are fine! I''m sure about that! When I upgraded to 122 I didn''t notice this problem until I rebooted after 5 days. Hope someone knows? -- This message posted from opensolaris.org
Did you upgrade the OS or did you also do a zpool (or zfs) upgrade? An OS upgrade will not do a zpool upgrade. If you did not do zpool upgrade, then you should be able to boot into the previous boot environment. On Sep 12, 2009, at 8:16 AM, Hamed wrote:> Do you thing that this is a bug?

The summary of code changes for each release is available at the download center. For example, http://dlc.sun.com/osol/on/downloads/b121/ -- richard
Actually I did both :( upgraded zpool from version 14 to version 18. I did it manually after my OS installation. Right now i''m copying all my data from the zpool but the speed is very poor! 900 KB/s, usually I have around 50 MB/s -- This message posted from opensolaris.org
