May 21, 201313 yr ok update, went back to win explorer and now tower is showing up. all disks. even disk which shows disabled. pic 4 Is that weird? Now everything seems to be working fine. i'm Confused. Okay, it's not uncommon that Tower "disappears" from the Network ... but it will often "come back" after you've accessed it via the actual address with Explorer [i.e. \\Tower\Disk1 or \\Tower\Movies ]. The fact that it's been accessed resets the network topology display in Windows. HOWEVER ... you DO have a significant problem => it seems that Disk 2 has failed. When you say you can see "... all disks. even disk which shows disabled ...", I believe you're referring to the Windows Explorer display -- correct? Can you still not get to the Web GUI display? Try this: On a DIFFERENT PC on your network (laptop, desktop, or even a tablet) go to your web browser and enter //Tower and see if it shows the Web GUI. If you can get to the display, what does it show for Disk2 I THINK (but the Web GUI will confirm) that Disk #2 has failed and needs to be replaced ASAP. The reason you can still "see" it in Windows Explorer, and access its files, etc., is that UnRAID is reconstructing the data from the other disks plus parity ==> that's what "fault tolerance" is all about !! That's almost certain (I've never seen UnMenu be wrong about the disk status info) ... but it would be nice to access the Web GUI just to confirm.
May 21, 201313 yr ... by the way, if you don't have a spare 2TB disk, you should order one !! Assuming that's indeed the problem, you're running "at risk" until you replace the disk and let the system rebuild it. ... meaning that any other disk failure will result in lost data.

DISK_DSBL_NP = Disk Disabled - Not Present. Either the disk itself has failed, or a power/data cable to it is loose or disconnected, or the drive tray it is in is loose/poorly seated, or the disk controller port it is connected to has failed.
May 22, 201313 yr Author Ok didn't have time to try your suggestions. I will try tomorrow. Will this be a good drive to add? http://www.newegg.com/Product/Product.aspx?Item=N82E16822236343 any recommendation will be appreciated Thanks

May 22, 201313 yr Author Ok I am about to pull the trigger on a the WD Red drive, to replace bad one, and a new case (http://www.newegg.com/Product/Product.aspx?Item=N82E16811147164) This case has 8 fans. What can I do to control them? Is there a controller that can control them and not have them run full speed all the time? I have the server in the my living room and my current case has one fan and its very noticeable. Thanks, Oscar
May 22, 201313 yr Is there a controller that can control them and not have them run full speed all the time? I have the server in the my living room and my current case has one fan and its very noticeable. Is the case in a rack? If not, you may want to consider a tower case with 120mm fans ... they're generally MUCH quieter than any of the server-oriented cases. How many drives do you need the case to support? In any event, there are several options for fan controllers: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=40000011&Description=FAN+CONTROLLER&Tpk=fan%20controller ... I don't see any with 8 channels, but you can put 2 fans on a single channel.
May 23, 201313 yr Author I currently have 8 2TB drives and I want to future proof the server. I plan on expanding. Most cases I see have room for 8 to 12 drives. I figure I can see how using a few fans and see how the temp on the server drives holds. I think I will run the three middle fans at first and see how it reacts.
May 23, 201313 yr I currently have 8 2TB drives and I want to future proof the server. I plan on expanding. Most cases I see have room for 8 to 12 drives. I figure I can see how using a few fans and see how the temp on the server drives holds. I think I will run the three middle fans at first and see how it reacts. You want even airflow over the drives -- only having airflow in the center will work fine for the drives in the center section; but isn't a good idea for those on the ends. Consider airflow carefully when choosing a case. This is an excellent case for up to 15 drives: http://www.newegg.com/Product/Product.aspx?Item=N82E16811112388 12 of the drives mount VERY EASILY in internal bays, and there are 3 140mm fans blowing directly over them. There's room for 3 more drives in the 2 5.25" slots, using a 3-in-2 adapter (which would have its own fan). There are other alternatives for up to 24 drives ==> this monster has space for 6 120mm fans that will blow directly over 20 internally mounted 3.5" drives; plus has 6 additional 5.25" bays that could easily hold any additional drives you might want. http://www.lian-li.com/v2/en/product/product06.php?pr_index=628&cl_index=1&sc_index=25&ss_index=138&g=f And remember - 120mm and 140mm fans are large enough that you can easily run them at relatively low (e.g. SILENT) speeds and still get very adequate cooling
May 23, 201313 yr Author Wow, those are nice cases. What I meant by running the middle fans, my thinking is running the three middle fans that would draw air from front to middle where the fans are. Or I will run the front fans only and see how loud they are. I mainly use the server for movies and data back up. I don't think that the drives are being over worked. I see them on my current setup running at 28-30 deg C with one fan blowing out the back. I found the case for $99. on new egg. I only wish they had a 5.25 bat to install a controller. If I have room I mat think of installing on the side of the case.
May 30, 201313 yr Author ok Sorry for the delay in replying. I received my new case and 2TB red drive. I transferred MB, Power supply and drives to new case. fired her up and Unraid is off line. all Drives are green except for disk 2 it has a blue dot. Question: Do I start the array and let it rebuild disk 2 or is there something else I need to do.. Thanks, Oscar
May 30, 201313 yr ... all Drives are green except for disk 2 it has a blue dot. Question: Do I start the array and let it rebuild disk 2 or is there something else I need to do.. A Blue dot means the disk isn't part of your array !! Somehow UnRAID doesn't think you have a disk 2. Not sure exactly what you have done to this point, but consider the following ... => In Reply #24 you showed the Web GUI, which showed that Disk #2 was Disabled and Not Present => In Reply #25 you indicated that you could access disk #2 from Windows Explorer What this means is that UnRAID "knew" about disk 2; but was emulating it by reading all the other disks plus parity and reconstructing the data for the disk that wasn't there. SOMEHOW that status has changed. It may be that you simply need to Start the array, and it may then show you a "missing" disk #2, or it may recognize the physical disk and provide a different status (red if it thinks it's bad, or green if it recognizes that it's the same disk). I'm not sure, but PROCEED CAUTIOUSLY !! What I'd suggest is to Start the array and see what it shows. If it wants to Rebuild Disk #2, that's okay. If it wants to Format #2, that is NOT okay -- you'll lose all of the data. Start it up and post back with what it shows ...

A Blue dot means the disk isn't part of your array !! Somehow UnRAID doesn't think you have a disk 2. No, it thinks disk2 is NEW. Not sure exactly what you have done to this point, but consider the following ... => In Reply #24 you showed the Web GUI, which showed that Disk #2 was Disabled and Not Present Because the array was started when it was NOT present, unRAID forgot its model/serial number, therefore, it now thinks it is a replacement for itself. => In Reply #25 you indicated that you could access disk #2 from Windows Explorer What this means is that UnRAID "knew" about disk 2; but was emulating it by reading all the other disks plus parity and reconstructing the data for the disk that wasn't there. SOMEHOW that status has changed. It may be that you simply need to Start the array, and it may then show you a "missing" disk #2, or it may recognize the physical disk and provide a different status (red if it thinks it's bad, or green if it recognizes that it's the same disk). I'm not sure, but PROCEED CAUTIOUSLY !! It might have been a loose cable t the drive, and it might now be making connection, so if the loose cable has been crrected, you can start the array and unRAID will reconstruct the contents of the drive onto itself. What I'd suggest is to Start the array and see what it shows. If it wants to Rebuild Disk #2, that's okay. If it wants to Format #2, that is NOT okay -- you'll lose all of the data. Start it up and post back with what it shows ... As suggested, you can start the array and let the reconstruction begin.
May 30, 201313 yr Author Ok I started the array last night and unraid started to rebuild disk 2. Disk 2 is a WD red 2TB that is new. Is it possible that the hd I removed is ok? I am out of sata ports so need to get another hd controller to add another disk to the array. I have 8 total disks now, but I have a few 250 and 500 gig drives that I could add. Is there a PCI card that has more than 4 ports or PCIe controller card? Rebuild was at 47% this morning. I hope it is done by the time I get home. Thanks for all your help Gary and Joe Oscar

Is there a PCI card that has more than 4 ports or PCIe controller card? Rebuild was at 47% this morning. I hope it is done by the time I get home. Thanks for all your help Gary and Joe Oscar As Joe clarified, UnRAID no longer knew the serial # of the drive, but it did know there was a Drive #2 in the array ... so it simply started a rebuild when it was started. That's excellent .. it means when the rebuild finishes you'll have a good, clean array again. As for whether or not the old disk is still good -- it could be .. it depends on just what happened in the first place. After the array is in good health, and when you have a spare SATA port, I'd connect the drive and run Joe L's Pre-Clear script on that drive. If it passes 2-3 cycles of pre-clear then it's fine ... and it will also be ready to add to the array immediately without the need for clearing. If it fails, you'll know and won't try to add a bad drive As for adding old 250GB and 500GB drives ... you could; but personally I wouldn't add drives that small these days -- you're "wasting" a SATA port that could provide many times that much storage with a newer, larger, faster, and more reliable (since it'd be new) drive.
May 30, 201313 yr Author Thank you Gary once again. The fans in the new case are very quiet. I am only running the 2 fans that are directly in front of the drives. 1 bay is full and middle bay has 3 drives in it. I removed the middle set of fans just to give me more space for now. All is good, Osc.
