WDC WD15EADS-00P8B0 I have five of those 00P8B0, some of them have a really high Load_Cycle_Count, or they become slow during a raid rebuild, or they just timeout when not using WDIDLE3.EXE (and using the default 8sec Intellipark feature which is really bad design) ... they are reported as BAD and "NOT RECOMMENDED" all over the internet. WD doesn't provide a decent solution yet for these. My three newer WD15EADS-00S2B0 are also running on the same Marvell controller and were never kicked out of the raid. Stable and decent speed. I didn't see any issue with those newer 00S2B0 drives, so I believe this is actually a WD issue and not a Marvell issue. Maybe the timeouts are not handled well by the Marvell driver and we're seeing mvs_abort_task , but that looks more like a symptom. I disabled the intellipark feature of the WD drives using WDIDLE3.EXE via a DOS usb bootable stick, and instead of timing out, the WD15EADS-00P8B0 just have become extremely slow now, iostat reports 1.5 MB/s writes to the raid rebuild drive. I believe the current MVSAS patches should be good enough if you avoid WD Green drives; Best regards, Audio Haven On Wed, Feb 10, 2010 at 12:32 AM, Orion Poplawski = wrote: > What's the status of the MVSAS patches posted in November '09? =A0I'm= just trying > to get started with mvsas and running into the mvs_abort_task issue. = =A0At least > one person has reported that stability improved, but it looks like th= ere were > some other issues with the patches. =A0Any chance on seeing this in t= he mainline > kernel soon? =A0Are there updated versions? =A0A git tree to pull fro= m? > > Thanks! > > - Orion Poplawski > > -- > To unsubscribe from this list: send the line "unsubscribe linux-scsi"= in > the body of a message to majordomo@vger.kernel.org > More majordomo info at =A0http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
