April 30, 201016 yr I saw this the first time I tried to add a new precleared disk to the array. I had 1 Parity and 1 Data and was adding a second data. All data disks showed as unformatted so I did nothing and started a thread ("I am in panic mode") on the forum. Ten minutes later after several forum interchanges, I did a stop start sequence and only the new drive (Disk2) showed as unformatted. I clicked format and all was well. I believe I saw the condition, all data disks saying unformatted, one other time, but I stopped and started the array and all was well. I think that was when I moved some disks around so all the array disks were in mobo SATA slots. Originally i Had Parity and 1 data connected to the mobo and two un assigned disks connected to the SASLP MV8 (one to each of the two SAS-8087 connectors through the SAS backplane. My array now has 1 parity disk, 2 data disks. There is one precleared drive ready to go into the array and one drive in the preclear process. When that drive (the fifth one in the case) clears I will add drive 4, which is precleared to the array. Right now, I have 4 disks (1 parity, 2 data, 1 Preceleared spare) connected to the Mobo and 1 disk connected to a SASLP MV8 controller being precleared. Later today I will add disk 4 to the array. I will then have 1 Parity, and 3 data connected to the mobo and a precleared spare connected to the SASLP MV8 HBA.
April 30, 201016 yr oh man, thank you for posting that. It was as simple as that for me too. I had 1 parity, and 1 data drive. I added a new one last night, let it format. When I woke up today, BOTH data disks showed as unformatted and shares missing. I hit stop, waited 10 seconds, hit start. The data was back on the original data drive.

Post a syslog, before you reboot. It will help Tom a whole lot.
April 30, 201016 yr Same here. Added a 3rd data drive (not pre-cleared) and when when the array came back up all drives showed as unformatted. Stop/Start of the array bought things up as expected (only the 3rd disk showing unformatted). I don't think I've rebooted since - I'll look for the syslog tonight. Retrieved the syslog, so created a clean thread at http://lime-technology.com/forum/index.php?topic=6221.0
April 30, 201016 yr I telnet into the server and look in /var/log - I think you can also get them via unmenu if you have it installed.
April 30, 201016 yr Silly question. I've looked around, where are the logs located or accessed from? They are in /var/log/syslog Instructions to capture it are here: http://lime-technology.com/wiki/index.php?title=Troubleshooting#Capturing_your_syslog You can also get to it from your browser, and then just "save as" to a file on your PC, zip it, and then attach it to your next post. Type //tower/log/syslog or to get to an older copy if it has been rotated out since you last rebooted. //tower/log/syslog.0 or //tower/log/syslog.1
April 30, 201016 yr Thanks for the info. //tower/log/syslog was the easiest solution. I've attatched the .txt file, starting from the initial start with the new Hard Drive. Hope it helps to solve the issue. syslog.txt
April 30, 201016 yr DAMM DAMM DAMM DAMM I just did it and screwed my self. Now to see if I can recover what is on the drives. It is not a disaster as I have all of the orginal material, its just about a weeks worth of time DAMM DAMM DAMM before you do anything, post a syslog. It might contain clues that helps lime-tech. Then, follow instructions as described here: http://lime-technology.com/forum/index.php?topic=6199.msg60080#msg60080 Joe L.
April 30, 201016 yr Author I pulled that post and am reposting now. I am two excitable with all the stuff going on about this. I have an issue but it is minor and I will post the syslog (attached) I had 5 drives in the system. 4 direct connected to the mobo sata ports one connected to the SAS controller. The 4 on the mobo are parity, Data1, Data2, all of these are in the array and fine. The fourth disk which is on the mobo also was precleared last week with 99% certainty but with my memory .... I really need to start writing things down!!! Yesterday I installed the fifth drive connected to the SASLP MV8 controller and precleared it. I now started to add the new drive, the one directly connected to the mobo, to the array. [note] The drive letters changed parity used to be flash=sda, Scratch=sdb, parity=sdc, disk1=sdd, disk2=sde; and preclear (old)=sdf. Now the assignments are flash=sda, scratch (a USB drive)=sdb, parity=sdd, Disk1=sde, Disk2=sdf, Disk3(old precleared now in the array)=sdg and the new precleared connected to the SASLP MV8 is sdc. I assume the bios or kernel scansthe mobo after the SAS LP MV8 is scanned for drives. It came up the first time as just the sizes of the disks after I hit start. Being impatient I panicked and wrote the post I removed. I then realized I never hit the format button!!! I went back stopped the array and restarted it and the bug showed up. All of the three disks were marked as unformatted. But now I was thinking straight!. I stopped the array and restarted it. It came up with the two data disks (1 and 2) showing the correct size, percent used etc. The third disk now showed as unformatted and the format button was showing and enabled. I pressed it and minor panic 2 set in. It said formatting (third disk only) but it took about ten minutes to do that!. Eventually it came back and everything looks correct. I thought that the formatting of a precleared disk only took a minute or two. If that is not the case then I have no issue. syslog-20100430-175842.zip
May 3, 201016 yr Just wanted to update. I added yet another drive today to the array. After Starting the array with the new drive. It came up as Unformatted, along with all my other drives. After a stop, and start of the array. It appeared normal again, with only the new drive unformatted.
