I get the above message, when I try to drop a lot of files on to my NAS.

i7-930
GA-X58A-UD3 rev2.0 (firmware FH, latest)
6GB DDR3 Corsair 1600 9-9-9-24 1.65
6 x 3TB Segate

running off a USB 16GB flash drive with ZFS1

I really could use some help to get this to stop. A reboot fixes this every time, but when I try to drop lots of data onto the system it eventually starts the ahcic loop of failure and never gets out of it. System runs, but super slow, almost inaccessible, as usually it fails during a copy and still tries to copy the reminder.

BTW I love freeNAS80, first install, and already saw the power, reading and writting to my NAS from windows at 80MB/s. I am really impressed with that. Got 3 GLAN connections on it and waiting for my link aggrigation switch to come in to make it even better. Really want to figure out what is going wrong. Also have memory on order to beef it up to 24GB, or 38GB (if motherboard lets me put in 8GB stick).

BTW, small drops of a few GB no problem, very fast.... big drops of Terabyte+, ahcic loop eventually kicks in and makes the system unusable. It has happened with me dropping large file copies, lots of files. As far as reading from the NAS goes, I never need anything bigger than 10GB, and so far it has been flawless (but hardly tested - so it too may eventually show this flaw as well).

What is your sata controller? It really looks like a driver bug with your controller, I do not really see any way around it.

Thanks for the reply.

South Bridge:

6 x SATA 3Gb/s connectors (SATA2_0, SATA2_1, SATA2_2, SATA2_3, SATA2_4, SATA2_5) supporting up to 6 SATA 3Gb/s devices
Support for SATA RAID 0, RAID 1, RAID 5, and RAID 10


Marvell 9128 chip:

2 x SATA 6Gb/s connectors (GSATA3_6, GSATA3_7) supporting up to 2 SATA 6Gb/s devices
Support for SATA RAID 0, and RAID 1

* SATA3 RAID 0 4x and SATA3 2x performance are maximum theoretical values. Actual performance may vary by system configuration.
* SATA3 SSDs are not recommended for use in RAID 0 mode on Marvell SE9128 ports.

GIGABYTE SATA2 chip:

1 x IDE connector supporting ATA-133/100/66/33 and up to 2 IDE devices
2 x SATA 3Gb/s connectors (GSATA2_8, GSATA2_9) supporting up to 2 SATA 3Gb/s devices
Support for SATA RAID 0, RAID 1, and JBOD

The bolded is the current SATA I am using it is set to plain IDE mode in the bios. Have 4 more available by marvell and gigabye. I set all features to plain IDE in the bios.

I can swap out the board, just want to make sure that its faulty, and not some setting I have forgotten to adjust.

 

[William Grzybowski]

Ok, IDE is the very old legacy mode that should be avoided, please switch all of them from IDE to AHCI (or SATA).

Do you have same problems on any other controllers? Or just the one in bold.

 

[no1ninja]

Just the one in bold, is in use. As I wrote that, I was thinking the same thing, I probably should switch it AHCI. Will do that now, so far its been working good, with small loads, hope this does the trick. Really like this MB because it has 10 SATA connectors, and means that in the future I can add 4 more drives if the system requires it.

Thanks for your help, will change it and post here if the problem shows again, if I don't consider this problem solved.
