Re: libata pm
Hi everybody,
it looks like this will be a never ending story...
After I got the new PSU and the raid was in full sync without any
error for 48h, I thought all problems were gone. Today the sata errors
reappeared and whenever the load is high enough I get the following:
I exchanged two (probably failing) of the eight harddrives with new ones.
All remaining disks have a good smart state and are fully readable when
the raid is not active. As long as I mount the filesystem on the raid
readonly there wont happen any error, but the moment I mount it rw and try
to copy something to the fs on the raid I get the already known timeout.
At least I get a little bit desperate now...

Re: libata pm
Shuffling the drives did not change anything to the linkspeed of the 3 ports running with 1.5 Gbps. Looks like the problem is port-related. Hmm... Okay. Maybe the signal traces or connectors have some problems. But 3.0Gbps on downstream port doesn't make any difference anyway so unless it leads to errors, it should be fine. The first PSU (Multilane) offers (measured) 12,20 V on both lanes. This falls during read/write access on all drives attached down to 12,10 V. That explains the PHY dropouts. I've even seen drives to do hard reset accompanying emergency head unload due to voltage dropping when high IO load hits. Of course, data in cache is lost. The second PSU (Singlelane) offers (measured) 11,75 V. This doesn't change during read/write access on all drives attached. I tested the second PSU without anything attached and it still offered 11,75 V. 11.75 is still in spec and it doesn't fluctuate. I like this power much better. I will try to add another PSU this evening and remeasure. Currently the whole machine needs about 350W. The PSUs are Targan 500W (Multilane - 2x12V 10A) Maybe one of the lane is only connected to video power connectors? IIRC, that was the idea of multilane power anyway. Please lemme know your test result. Sorry for my late answer, but i had to sort this out first. After replacing the first PSU with a new Corsair 650W the power no longer fluctuated more than 0,01 V (and this only when booting up the drives...) I did a full resync on both raid arrays and got no more errors or resets, but there were some inconsitencies during sync and the xfs filesystem on both arrays had to be repaired. Are these problems caused by the pm resets ?

Hello,

With one, two and three drives on the pm I got no errors, so I tried to
change the power supply. I got two power supplies for the 16

Sorry for the
confusion.
It's amazing that, in SATA, PSU-problem-verified / PSU-problem-suggested
ratio is significant. I don't think this ever was the case with PATA. SATA
link seems much more susceptible to power quality and allows hooking up
whole lot of drives.
The only remaining issue is that some sata links are only working with
1.5
gbps and I can't figure out why. (ata3,4,5,6.x are the Maxtor drives and
ata7,8,9,10.x are the Samsung ones)
Hmm... That's how the hardware negotiated transfer rate w/ each other.
SControl is telling the hardware that there's no speed limit and to go
as high as it can but somehow 3.0Gbps negotiation failed and the link speed
is limited to 1.5Gbps for some of the ports. Is the result always the
same? What happens if you swap drives between ports? Also, if you have
an extra PSU lying around, can you hook it up with some of the drives such
that the load is more distributed.
Oh.. Another note on PSU. I don't know whether this still holds for
more recent ones but mid-to-high range multi-lane PSUs sometimes have
lesser juice on 12v rail available for disks than low cost single lane
PSUs. This is because high power 12v lanes are allocated to power video
cards and disks can only pull power from (usually) single weak 12v lane.
Thanks.

The PSUs are Targan 500W (Multilane - 2x12V 10A) Maybe one of the lane is only connected to video power connectors? IIRC, that was the idea of multilane power anyway. and Noname 350W (Singlelane - 1x12V 10A) so this 'should' be enough... This night i copied the backup back to the first raid (the Maxtor drives) without any error but during the transfer i got this on the second (mounted but unused) raid: ata10.00: failed to read SCR 1 (Emask=0x40) ata10.01: failed to read SCR 1 (Emask=0x40) ata10.02: failed to read SCR 1 (Emask=0x40) ata10.03: failed to read SCR 1 (Emask=0x40) ata10.04: failed to read SCR 1 (Emask=0x40) ata10.05: failed to read SCR 1 (Emask=0x40) ata10.00: exception Emask 0x100 SAct 0x0 SErr 0x0 action 0x6 frozen ata10.01: exception Emask 0x100 SAct 0x0 SErr 0x0 action 0x6 frozen ata10.02: exception Emask 0x100 SAct 0x0 SErr 0x0 action 0x6 frozen ata10.02: cmd ea/00:00:00:00:00/00:00:00:00:00/a0 tag 1 cdb 0x0 data 0 res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) Timeout during heavy IO can be caused from a number of things and bad power is one of them.

I can test the pm with two Maxtor drives tomorrow (currently backing up the raid). With one, two and three drives on the pm I got no errors, so I tried to change the power supply.

Sorry for the confusion. The only remaining issue is that some sata links are only working with 1.5 gbps and I can't figure out why.

Re: libata pm
I could solve the problem by ncq blacklisting the Maxtor 6V300F0 devices
