April 26, 201115 yr Version 4.7. Everything was going fine, I decided to add a brand new hd into my array, hooked everything up and now I'm getting 2 missing disks. So I moved some power cables around and now I'm missing all my disks. Went back to original setup, still missing disks. Is my PSU not powerful enough? I believe it is 520w, is that not good enough?
April 26, 201115 yr Is it a single Rail on 24 volt. if so you might need to do some balancing to make it work.... let say there are 4 24V rails then all the drives on one rail is bad. if you have 4 drives the best would be one on each.... but this is not taking in to acount what rail the mother board and option cards are using. but it is a start. if you are on a single rail easer how may disks do you have?, did you check the SATA side?

This is the PSU I am using: OCZ ModStream OCZ-520 12U http://www.silentpcreview.com/article208-page1.html I am assuming by rails you mean input thingys? So yes I have 4 and before I had 2 on each and I am still moving them around, but still nothing.
April 26, 201115 yr On the main page it should list the expected disk for each slot in italics, just below what it has for each disk now. Try going to the devices page and re-assigning the drives to match what the main page says. Peter

As for my PSU, is 520W enough? 5HD(4-2TB, 1 1TB)?
April 26, 201115 yr I'll try to do that, but unfortunately now my computer wont boot... As for my PSU, is 520W enough? 5HD(4-2TB, 1 1TB)? What kind of drives and what are the specs of your system? EVERYTHING draws abit of power. For a PSU, it's not all about the watts listed, but on how you distribute the load across multiple rails.
April 26, 201115 yr No Not the input connectors. A power supply creates power and then the company will try to balance safey and performance by having rails. read the power supply sugjestions in the manual that can explain better. the one you have seems to have a single rail. so I think rechecking your connections is the best starting point. then try to remove the new hard drive. if then every thing starts correctly you might need to consider the power supply. I see that this power supply had removable connectors so check the connections at the power supply as well.
April 26, 201115 yr Your power supply is listed as having one +12V and it is 28A. That should be more than enough for 5 drives. Most likely, your boot order has been messed up in the BIOS by you re-arranging the disk connections. That will also mess-up unRAID and you will have to re-assign the drives to get it back right. Check the BIOS for the boot order and then check the drive assignments. Peter

Peter Well I figured out that the first 4 sata are handled by the nVidia controller and the other 4 are handled by the silicon controller so I had to enable those. So I just got in and 2 quick things: A - It appears as though 2 of the hd's have switched spots. I thought unraid is able to correctly figure that stuff out? is it because one of the drives it the parity drive, is that what caused it to do that? B - Will my new unformatted un-anything hard drive show up in the devices tab? And the command to format is ./preclear_disk.sh -A /dev/sdX right?
April 26, 201115 yr And the command to format is ./preclear_disk.sh -A /dev/sdX right? Wrong. That is the command to clear and partition a drive for a partition starting on sector 64. It does not format anything.
April 26, 201115 yr I am running version 4.7. I installed a Supermicro CSE-M35T-1B 5-in-3 drive cage and inadvertently moved some drives to different sata ports, when I booted the server the I received a similar message regarding missing disks ("ERROR:TOO_MANY_MISSING_DISKS"). Once I reassigned the correct drive as the parity drive, the array worked properly again. I don't think it's your power supply.

It does not format anything. That's what I meant. It was a brand new hd so ya I needed to advance format it. Also to do the preclear I decided to telnet into the machine. My computer restarted for some reason, so now how do I get back in? Is the preclear still running? This is what I see root@Tower:/boot# screen -r There is a screen on: 23450.pts-0.Tower (Attached) There is no screen to be resumed. root@Tower:/boot#

B - Will my new unformatted un-anything hard drive show up in the devices tab? And the command to format is ./preclear_disk.sh -A /dev/sdX right? A- Pre 5.0b6 unRAID ties the drive to the assignment by serial# and port so if the port changes then the assignment changes. I believe the new beta only uses the serial numbers so it would have figured it out. It has nothing to do with the drive being the parity, however be VERY careful with parity assignment. B - Every connected drive should show-up for the devices page. If a drive doesn't then you have a problem, possibly with the controller not having an unRAID driver. You don't add the drive until you are done with the preclear. Peter

Is it going to stop the original preclear?
