June 6, 201313 yr Ok, I've got the server up and running. Loaded unMenu, preclear and screen. Going through the tutorial step by step, and went to list my available drives; preclear_disk.sh -l And I got back the following; =================================1.13 Disks not assigned to the unRAID array (potential candidates for clearning) ===================================== No un-assigned disks detected So I guess I can't even read the drives in my server.....weird. Must be the controller cards that I have (3x IBM M1015)? But I think unRAID can see the controllers, because when I type in; demsg|grep SATA|grep link it spits out the following; ata4: SATA link down (SStatus 0 SControl 300) ata5: SATA link down (SStatus 0 SControl 300) ata3: SATA link down (SStatus 0 SControl 300) ata6: SATA link down (SStatus 0 SControl 300) ata1: SATA link down (SStatus 0 SControl 300) ata2: SATA link down (SStatus 0 SControl 300) Or would those just be the SATA headers on my motherboard that it can find? The mobo does have 6...... I could connect to those, but then for sure I wouldn't be able to use my whole system on unRAID, unless someone knows what else I could do?

It could be that they are not getting power? Joe L.
June 7, 201313 yr Author Nope, they all have power. All the drive bays are lit up. I have a redundant power supply, so it's not going to be that either. Ugh. I'll have to unscrew the fan plate to switch out the SFF8087x8087 cables for a couple of break out cables to hook to the motherboard....... Then I'll see if anything changes.
June 7, 201313 yr Author Yup, can't read them through the controller cards. I've even crossflashed them to IT mode (straight passthrough). Oh well, I guess I'll have to figure something else out afterwards. But at least I might be able to run the preclear on them now. UUUGHHHH!!! Now I can't log into the server to set up Mail and SSMTP to email me when the preclears are done!!! I've even rebooted the server.....frustration!!
June 7, 201313 yr Yup, can't read them through the controller cards. I've even crossflashed them to IT mode (straight passthrough). Are you using the latest unRAID rc13? or the much older 4.7? Joe L.
June 7, 201313 yr Author Ok, I found out that my router was giving me problems. Shut it down for a while, and now it's working fine. I have unMenu, preclear, screen and SMTP loaded and have successfully tested SMTP too. So, now I need a bit of help with running preclear on the first 6 drives. I'm going to want them to run for 6 cycles (I'm going on vacation for a week, so might as well let them go). And I'm going to want an email sent to me letting me know when they've finished and what the results were.....so I'm guessing this would be the code to input for each drive (lettered b,c,d,e,f and g); ./preclear_disk.sh -r 65536 -w 65536 -b 2000 -A -c 6 -m [email protected] /dev/sdb Would this be correct for the first drive? Is everything in the right order? Does it matter what order everything goes in? I'm getting excited to start this running. I'm using the stable version 4.7 that was shipped to me. I'll upgrade it once I get back. I'm not too worried about the controller cards at this point. Just getting the drives to test is a huge step forward.
June 7, 201313 yr Author Ahhh, I couldn't wait to find out if my code was correct or not. But it's running on all 6 disks. Thanks for all the help so far. I'm not going to change this to [sOLVED] yet in case my code isn't quite right. I could stop the preclears tomorrow and run the proper code instead??? Actually, I'm not sure if I could stop preclear once it's been initiated. To a night of running!!!! Cheers!!!

Actually, I'm not sure if I could stop preclear once it's been initiated. The command line looked fine. To a night of running!!!! Cheers!!! "A night" no... Assuming 3TB disks, it will probably take somewhere between a week or two for 6 cycles of 6 disks. I trust you installed and tested your mail command, since I see you added the -m option for mail notifications. As you said... Now it is just a matter of waiting. Enjoy your vacation, I hope your server is on a UPS.
June 7, 201313 yr Author "A night" no... Assuming 3TB disks, it will probably take somewhere between a week or two for 6 cycles of 6 disks. A night of running, to see how fast it works. So far they're all at about 99% on the Pre-read of the first of 6 cycles at just over 6.5 hours. I see one has changed to Zeroing 1 of 6. How many stages are there per cycle? I'd like to get an idea of how to calculate how long it should take. I'm not concerned with how long it will take for the preclear to run. I just hope that it takes up at least the amount of time while I'm gone. Because I'll have to run it again 3 more times to check all of my HDD's. I did read this; 1. gets a SMART report 2. pre-reads the entire disk 3. writes zeros to the entire disk 4. sets the special signature recognized by unRAID 5. verifies the signature 6. post-reads the entire disk 7. optionally repeats the process for additional cycles (if you specified the "-c NN" option, where NN = a number from 1 to 20, default is to run 1 cycle) 8. gets a final SMART report 9. compares the SMART reports alerting you of differences. but I'm not sure as to which of these 9 are going to be a full read or write stage. I'm guessing from the above that there will be the 3 in RED that are the ones that take a good deal of time. If I am correct, based on the pre-read performance it could finish in just under 5 days. So far they are all averaging around 130 MB/s and a temp of 29-30 deg. Looks good. BTW, I love unMenu's myMAIN tab. It's easy to refresh and see how all the drives are doing, and what stage they're at. No need to get into telnet & screen. But I will check that out shortly to see what type of information it gives. I trust you installed and tested your mail command, since I see you added the -m option for mail notifications. I have unMenu, preclear, screen and SMTP loaded and have successfully tested SMTP too. Yup, I did install and test the mail command. Set it up with a gmail account as there was a great topic in which someone covered how they got theirs working.....and I just followed suit; http://lime-technology.com/forum/index.php?topic=26414.msg230995#msg230995 Enjoy your vacation, I hope your server is on a UPS. Totally forgot to grab one of my UPS' from my other set-ups. I'll keep my fingers crossed that I don't have any problems while I'm gone. It is only a week. I know I left some questions, but I think I'll still set this to [sOLVED]. The server is up and running preclear. Thanks a TON for all your help so far Joe. Totally amazing!
June 7, 201313 yr I'm using the stable version 4.7 that was shipped to me. I'll upgrade it once I get back. I'm not too worried about the controller cards at this point. Just getting the drives to test is a huge step forward. Reason I asked is that the 5.0 version has more drivers in it for more current disk-controller chipsets, therefore, once you try it you might find your additional disk controllers are usable.
