November 13, 200916 yr I could not find the md driver source and .config file to recompile the kernel. Perhaps I missed it, anyone see it on the beta8 distribution? http://lime-technology.com/forum/index.php?topic=4625.msg42437#msg42437 I found it in the normal place, inside /usr/src/linux/drivers/md directory. /me slapping head. Seems my root cleanup script (to free root initramfs space) was cleaning this up. With all the extra gunk packages install I thought it necessary to clean up much of the man.doc.src.share files. Ooopsss...
November 14, 200916 yr These cards are very tempting... £85 in the UK is a great price for an 8 port sata card. Let us know how you get on.
November 16, 200916 yr Great cards, especially for Norco 4220 users with their SFF-8087 connectors. Keep cable clutter down, optimizing cooling efficiency in the server chassis. Would just love to see support for these cards in unRAID.
November 19, 200916 yr Has anyone tried the latest beta with one of these cards yet? Mark read a few posts back. the drivers for these cards aren't included in the stock linux kernel. they're not built into unRAID, so it won't work
December 3, 200916 yr This is a card I want so it's looks like it's not unRAID:s issue to get it to work ? do we need to wait on a updated kernel ? Can some Linux guru look into this ? perhaps there are a solution anyway http://www.hardforums.com/showthread.php?t=1397855&page=10
December 3, 200916 yr So how would this card run in a PCI-E x1 slot? I'm trying to narrow down my MB selection for my media server, and was just curious about this card. Hopefully the support will be there before I need to get a card. One of the MB's has 6 onboard SATA connections, the other 10... so it'll be quite a few months before I need the card.

Can some Linux guru look into this ? perhaps there are a solution anyway http://www.hardforums.com/showthread.php?t=1397855&page=10 The drivers are rather young at this point based on typical bug reports [ http://bugzilla.kernel.org/show_bug.cgi?id=14534 ]. It looks like you will need Kernel 2.6.32.x (at the earliest), if not one of the patches that are certain to come later.
December 4, 200916 yr This card has Red Hat support I believe. How do they do it? They probably compile in the drivers. I believe the issue is not so much linux support as it is unRAID & emhttp support. Right now there seems to be enough on limetech's plate in resolving some lingering issues for the current beta.
February 22, 201016 yr Has this card been tried with 4.5 final? I presume not, as there'd be dancing in the UnRAID streets ... but just want to confirm before I finalize my order for the parts for my new UnRAID server.

I presume not, as there'd be dancing in the UnRAID streets ... but just want to confirm before I finalize my order for the parts for my new UnRAID server. My dancing shoes have been ready for quite some time. Actually, they're just my regular shoes, but I dance in them anyway. So far no cause to bop, jig, grind or hustle.
February 24, 201016 yr I've got one of these cards coming (out of stock) so I'll probably try and get it running in a test box with unraid. Also have some SAS drives to play with too. Not sure how fast it will be anyway, read some bad things about the current linux drivers. Actually I read some bad things about the windows drivers too so it might potentially end up on fleabay.
March 1, 201016 yr Can limtech say if this card will be suported? The drivers have to be in the main linux kernel before unRAID can support it. Do some google searching to find out if this card even works well in linux, and what kernel the drivers are in. Limetech does not write drivers for the cards. If/when it is supported and stable in linux that is when it will be potentially added to unRAID.
March 1, 201016 yr My card arrived today... My Ubuntu box recognised it without making any changes ( running 2.6.31-19-generic ) Performance looks ok, 10k 146g SAS drives are reading at about 90mb/s.

As anticipated, unraid 4.5.1 recognises the card, also recognises any SAS drives attached to it (but you can't add them to the array).

March 2, 201016 yr Sorry, as this won't help you, but here's the pointer for those who can compile their own kernels. The needed configuration entry for the kernel, when using make menuconfig, is under: Device Drivers -> SCSI device support ---->SCSI transports ------>ATA support for libsas (requires libata)

Please do me a favor? Post the output of this command on your Ubuntu system: lsmod Nevermind - I can see from your syslog which driver is being used. The 'stock' mvsas driver included with the kernel will not work reliably with SATA drives attached. The mvsas driver included SCST does work however & that is what I'm using to support this card.
