Re: [zfs-discuss] scrub halts

The latest changes to the sata and marvell88sx modules have been put back to Solaris Nevada and should be available in the next build (build 84). Hopefully, those of you who use it will find the changes helpful. This message posted from opensolaris.org

Re: [zfs-discuss] scrub halts

I now have a improved sata and marvell88sx driver modules that deal with various error conditions in a much more solid way. Changes include reducing the number of required device resets, properly reporting media errors (rather than "no additional sense"), clearing aborted packets more rapidly so th

The "reset: no matching NCQ I/O found" issue appears to be related to the error recovery for bad blocks on the disk. In general it should be harmless, but I have looked into this. If there is someone out there who; 1) Is hitting this issue, and; 2) Is running recent Solaris Nevada bits (not Sola

Point one, the comments that Eric made do not give the complete picture. All the tests that Eric's referring to were done through ZFS filesystem. When sequential I/O is done to the disk directly there is no performance degradation at all. Second point, it does not take any additional time in ldi
