Hi guys, I am running unRaid version 6.9.2 and last time I added a precleared disk, the array didn't notice it is already precleared and started recalculating parity again. What is the proper way of letting the array know a precleared disk will be added, so it do not need to recalculate the parity? Thanks! PS: I am using a pretty old Joe L. preclear_disk.sh v1.7 on a different (version 4.7) server, which actually shouldn't matter, no?

Nice setup! Mind asking how is the 10Gbps card, Mellanox MNPA19-XTR running? Did you had to do any adaptations in order to get it to work with unRaid?

4x 12T (IronWolf Pro) is pretty a huge volume, don't you think? Depends of course what you want. This definitely is a nice case, the way up to the 24 and 60 drive 19" enclosures (and I for myself am definitely not into those huge and cheap desktop cases, sorry).

One of the very nicest NAS-like enclosure for a 6-disk server is the Fractal Design Array R2 Mini case. I have here some pictures of it, in a server that I have built.

Yes, the ST8000DM004 is SMR and is much cheaper than the ST8000DM0004 which is PMR and the one filled with helium. I think those got mixed up above.

Cool, thanks! Running it now.

Is it safe to run the tunable tester on a loaded array? No data are overwritten?

Anyone used the U-NAS cases already and especially the 8x case? Putting a CHENBRO 84H323210-017 in the mainboard opening and an expander on it will basically make a DAS out of it and allow for daisy-chaining and expansions. Looks really nice, especially with the properly sized and mounted 120mm fans behind the drives.

Thats amazing! Looking forward to see you putting it together and your report on cooling. The WD20EARS should run pretty cool though.

Ordered the LSI 9200-8e and LSI 9201-16e to play with - both SAS 2008 chip based. Let's see if they can be flashed with the zip package provided in the first post of this thread?!

Guys, will the LSI SAS 9200-8e card work with unraid? It uses the SAS2008 chip and the mpt2sas driver in linux. I need something 6Gbps with external SFF 8088 ports.. Thanks for your advice.

Anyone can post where to get sas2flsh and which one exactly to get. I was looking at the link posted above but found only P18 and though the one supplied with P13 must be used? Anyone can sched some more light into this? Thanks much!

Anyone know if SMART information of the disks is passed through an M1015 controller flashed to LSI IT mode? Thanks.

It seems that this is not working any longer wget http://zion.mind-design.co.uk/unRAID/HandBrakeCLI-svn2354-i686-1ajb.tgz Could someone point to the current package? Thanks!

One of my favorites is the Supermicro SC847E16-R1400LPB for 36 hot-plug drives in only 4U. Here a review with images and a lot of details http://www.natecarlson.com/2010/05/07/review-supermicros-sc847a-4u-chassis-with-36-drive-bays/ The product page at Supermicro's site http://www.supermicro.com/products/chassis/4u/847/sc847e16-r1400lp.cfm

Any update on this cool projects and any more pics? Really enjoyed it.

This is a very nice case for 6 drive slot servers http://www.fractal-design.com/?view=product&category=2∏=42 2x 120mm fans can be put in front to cool the drives and blow to the back.

or modify the automounter like this: http://lime-technology.com/forum/index.php?topic=7536.msg95249#msg95249

Would be great to have an unMenu package for Handbrake CLI...

You may just ping all the ipads and iphones and HT appliances and if nothing is running starting the shut off timer. Same was mentioned above and the script shown.

The SLM2008 shouldn't clear the cache and thus don't need subsequent broadcasts in order to find the hosts. This feature should be enabled as soon as IGMP snooping is enabled on the router.

My rack is in a special purpose room, which has added cooling. Any dedicated cooling for the rack or do you just cool the room? Where goes the exhausted hot air from the back of the rack? Are there more racks in that room or is this half height rack the only one?

If money is a constraint then just get the Norco 4220 or 4224, put 3x 120mm DELTA fans in it and be done instead of getting all those Antec's and then load them with 5-in-3s... Yeah, rack is cool, but it is not silent because high CFM fans are needed to pull the air through the high-density drive bays. ccharmatz, btw, how do you cool that rack? Do you have a HVAC running to the back? And where is it located, is the room special purpose for equipment?

I used to run raid 6 with traditional $1800.00 raid controllers. This limited my flexibility with upgrading drives. I would have to upgrade entire arrays after copying all of my data off somewhere ( part of the reason I have multiple arrays ). I have never lost more than one drive at a time, yes it did give a little more peace of mind during a rebuild after a drive failure running raid 6. But then again with unRaid if I did experience a multi drive failure my risk is still mitigated, as only the data on the failed drives is lost. In my application (digital hoarder, I am trying to get help) I just want large amounts of protected space. I am not concerned with iops or being able to write to the array at over 300MB/s. I do have different classes of data, with a small subset of data I really care about. Some of this is actually copied across all three arrays, as well as on an off site server. An example of such data is family pictures and some (in my opinion, or my wife's) really important documents. This has been said I think more that thousand times in all the subforums and it is really time to put it somewhere on #1 in the FAQs so that all new or potentially interested users see this first prior seeing anything else! And btw, a large array is not one holding 14 disks but something with several thousand. 14x drives is just a disk group in such array usually protected by 1 or two parity drives (and yes they are smaller diskgroups and even mirrored ones, just depends on needs). Anyway, what unRAID does is exactly what anyone (experienced enough) would expect (from unRAID) and is exactly the reason why unRAID is chosen (for that particular need).
