Post 2 and 3 above and see if the problem goes away. If it does you can add one plugin at a time to find out what is causing the issue.

That's the way I would do it, I would also do an uncorrected parity check one after I rebuilt parity and two after each drive rebuild. It will take some time, but it will ensure your data is in check. Are you planning to preclear your new drives? This whole process could take a week or longer with preclear. at least this way you can stop and resume the process if you needed the data in the array without worrying about forgetting where you left off.

Post 5 and 6 of link http://lime-technology.com/forum/index.php?topic=15280.0

1. Plug in USB Drive 2. Open utilities folder 3. open Disk Utilities 4. Click on your USB drive in the left hand column 5. Click on first aid tab ( has 4 options first aid erase raid and restore) 6. Click the verify disk button in the lower right of box 7. Click verify and let finish.

Had a look through your syslog and found this just before the segfault: get_config_idx: fopen /boot/config/flash.cfg: No such file or directory - assigning defaults Your plash drive may be corrupted. Pull it out of the sevrer and perform an chkdsk on a another computer. Also check to ensure your config files are there. If you shorten your search term to emhttp[3324]: segfault in your favorite search engine a few threads will show up that may give you some guidance in fixing your issue.

Yes I would disable all plug ins. My understanding is that you have your drive causing problems on a motherboard sata port yes?

Remove simple features and see if the problem goes away. If it does I would post in the simple features thread so the developer knows of your issues

Looks like you have HPA on ata9, I'm not sure if that would be causing some of your problems or not. I am sure someone who has more knowledge about that will chime in I am sure. If you do a google search for HPA in unraid you will get a bunch of hits that may help you while you wait. Was ata9 in a gigabyte motherboard at some point in its life?

I would add that although 50C is a little warm it is well within its operating range of 61 high to 95 critical. What is your motherboard temp? If you do get it running again monitor your temps with a load and see where they top out.

Do you have any ports free on the Motherboard? You can shift to one of them and determine if the problem follows or if it's isolated to the M1015

First ensure you CPU fan rpm is where it should be. If it is then I would start by removing the CPU and cooler, clean both and reapply thermal paste. While it's apart you can inspect and clean the fan blades. Reassemble and see if that fixes you issue. Here is a wiki page that may help. http://en.wikipedia.org/wiki/Machine_Check_Exception

I can't help you, but it looks like the issue is effecting more than yourself. There is several entries in your system log that look like this -async,no_subtree_check,fsid=102 *(rw,insecure,anongid=100,anonuid=99,all_squash)' >>/etc/exports I googled it and found several posts having the same message. It may at least start you in the right direction. Edited for spelling error

It looks like you have both read and write errors on disk 0. I would first check to ensure your cable has not come loose. What power supply are you using?

Post a syslog and while your waiting if you have any add ons disable them and reboot to see if the problem goes away. Sorry misses the no add ons installed.

Try to stop samba and unmount the drives from a telnet session look here (cleanly stop the array from command line) http://lime-technology.com/wiki/index.php/Console#To_cleanly_Stop_the_array_from_the_command_line , reboot and restart new permissions. Wait for all your disks to complete before you do anything else.

One of these (Kingston Flash Card Reader MobileLite G2 USB 2.0) http://www.amazon.com/gp/product/B002RT69QQ/ref=oh_details_o06_s00_i00?ie=UTF8&psc=1 will let you swap the card with a new different one if it goes bad. The reader carries the guid and I know this one is unique. There's a version 3 out if you have USB 3. Not sure if it has a unique guid or not, but my guess is it does.

This is the case I just transferred my server into, it comes with 2x 4x3 bays, so 8 drives out of the box. I installed 2 istar 5x3 in my and I can verify that 4 5x3's will fit with maintaining the hot swap bay on the top. 2 draw backs for me were: 1. The access hole for the CPU cooler swap does not line up with my X8sil-f MB, small issue, but I left my passive cooler on there unsure how the case would perform. Lucky for me temps are fine with seven drives. We will see as my server grows. 2. The USB 3 cables are external cables and I have to run them to the back of the case. Not a big deal, but I think could have been done more efficiently. Other than those 2 it's a great case, lots of room cooling is good, and for me the case is reasonably quiet.

I shifted from a rack mount into a tower mainly because we moved to a new home and the server is now in my media room. My SuperMicro case fans were extremely loud, and my rack had a large footprint. My tower is very quiet. If noise and space for a rack mount are not an issue you will save money in the long run as the norco already comes with the hot swap bays. These are anywhere from $90-120USD.

The data I did find was from Nov 12, it was a Hitachi HDS5C4040ALE630 spinning at 5400rpm with 32MB cache. I am sure they would use other drives too, but have found nothing else. I would think if you are going this route you would choose the Seagate for $25 less when on sale. Has anyone got this drive before and are willing to give your thoughts?

Make sure you didn't knock the cable loose for drive 8 while switching around drives. Post a smart report for your parity drives

Smart report for disk 10 looks good

You might try photoRec or testdisk these are linux based and are on most recovery CD's that you can download. photorec was the only program I could get my photos and mp3's off a failing drive. There is a lot of work to do afterwards as the file names will most likely not give you a clue of what the file is other than file type. Unless the data is irreplaceable it is probably be easier to start over.

Here is a page that may answer some of your questions. http://lime-technology.com/wiki/index.php/The_Analysis_of_Drive_Issues I believe even with a drive swap unraid writes zeros to the drive before it is ready to be added to the array.

I have one, works great. Newegg has sales on those all the time if you are not in a hurry you could save anywhere from 5-10 USD.

Not sure if you have seen this thread http://lime-technology.com/forum/index.php?topic=26719.0 but it looks like the new firmware has some positive effects.
