Are any one using a LSI LOGIC SAS9201 and is it any good?

[GasMusK]

You don't name drives, you name pools. The choice of name matters.. if you have a pool called "tank" and you try to name a new disk 'tank' it will be added to the pool. On the other hand if you give it "bigdrive" then it'll be a new pool(assuming there isn't another pool with that name).

GasMusK: To be honest, if you aren't sure you need to be. Feel free to read my presentation, read the FreeNAS manual, etc. If you don't know I definitely won't know. So it's important that we have some common ground before we talk further. ;)

cyberjock, Ive named them Disk1, Disk2, Disk3... Disk10 so that would be 10 pools/disks?

 

[cyberjock]

Again, no way to know for certain since you aren't familiar with the terminology.

If they are indeed 10 separate pools you can destroy one pool at a time and remove that disk. if not, you won't be able to remove any disks until you destroy the entire pool. With that knowledge go read up on my newbie presentation and check out the manual and figure out which situation you fall under. ;)

Would removing 1 drive cause pool to fail if all drives are in the same pool and if so do i cause any permanent damage to the pool?

That depends on your pool layout.

Please, PLEASE go read my guide and the manual. It's near impossible to help you if you don't even know what you are doing. ;)

I´ve been reading and its still not clear to me, and the user guide for freenas 9.1.1 do not mention ECC ram att all... execpt "
Scrub:

similar to ECC memory scrubbing, ..."

 

[cyberjock]

ECC has nothing to do with your pool layout. I'm not sure why you think it would/should.

ECC RAM hadn't been directly mentioned until 9.2.0 I believe. The fact that so many had lost their pools to ECC RAM made it necessary to include that information.

But again, I'm really not sure where you're getting the idea that ECC RAM has anything to do with pool layout...

 

[GasMusK]

Im sorry my english skills is not up to par. I did not mean that ECC ram had any thing to do with pool layot. I was just remarking on it as this was the starting point of the conversation. As for the pool Im still trying to figure out if I have 10 pools or 1 pool with 10 drives in it... in other words to hang or not to hang. Im a slow reader and english is not my native laguage.

If it turns out its one pool. My only option is to get 10 drives and remove all data from the pool and then kill it and go back to windows where I know what Im doing...

 

[GasMusK]

It turns out that it is 10 pools, zpool status says:

You don't need FreeNAS to do what you're doing, you just need SATA ports. If you want to take advantage of that many disks for speed & SOME fault tolerance, you'd put several drives in a single volume/pool. 4 for RaidZ1, 6 for RaidZ2. I'm going against the grain & running 6x4TB drives in a RaidZ1, but I have a spare disk . . . just in case.

 

[GasMusK]

Laygo, I´m in it for the fact that I can use more than 24 disks as single/non spaned disks, windows have the stupid "C-Z" restriction and yes you could use "A-B" but then its still not 54 disks... and as space is my main concern both physical and in the TB sence, Ive chosen to go the route of no backups/redundancy as I can´t afford adding disks at the rate requierd to keep up with my obsesive hording... and in the end its still just stuff of the internet...

 

[no_connection]

I guess that's one way of storing files.
Scrubs should at least keep the drives internal ECC repairing weak bits, even if ZFS won't do much more than inform you of bad data, which is good I guess.

Not sure what the consequences of a bad RAM is to a single drive pool.
While FreeNAS is definitely not meant to run this way I don't see how it can be that much worse than windows.

I would schedule scrubs to be one or two days apart for each disk/pool, that way you might get some indication that ram is bad and you might minimize the damage somewhat.
But you need to have email reporting set up so you can catch problems quickly.

You could get a Dell T20 for the cost of little more than two 4TB drives and hook it up to any disk chassis you might have with a little bit of creativity. Especially as you already consider adding a HBA.
Let you current PSU take care of disks as the T20 does not have that powerful PSU.

 

[GasMusK]

no_connection, Im planing to get a new motherboard that supports ECC ram in the future as soon as my buget allows for it, as I need the ability to add 54 disks to it Im going to need a motherboard that has enough ports to handle a couple of HBAs. And until then I have to hope my luck holds out and that the fact that Im only adding data to one disk and pool at a time, and when its full i only read from them. A new disk added once the last one is full and allways one disk = one pool.

It's awfully expensive, but I believe (not sure, though) that it's been used without a problem.

I have LSI 9211-8i and 9201-16i cards in about 10 FreeNAS boxes and they work just fine.
When you have limited PCI slots and you need to fit 32 or 45 drives in a chassis, they are worth the expense.. For a typical home system, not so much.

Thats grate, I do need 54 hdds in my nas, and I guess Im not a typical home user =)

 

[GasMusK]

Ive been up and running my new LSI SAS9201-16i for about 5min now and still no problems =). It was a case of plug and play, just shutdown the nas and plugged the card and a new hdd in and booted up, and the system found the hdd no problem.
