April 22, 201016 yr I lost power yesterday, my UPS Battery failed (dead), so my UnRaid Did not shut down gracefully. Restarted and Parity rebuild started automagically... After about an hour, the rebuild stopped, I lost the web interface and had a drive with a noticeable "clickity clickity clickity" so it appears a "failed" drive may have stopped the parity... I powered down, removed the one drive that I suspected was the noise maker, rebooted the UnRaid and now have 3 other drives that UnRaid said is missing, so I need to check my power/SATA Connections, but assuming I get those other 3 "found" again... what should my next steps be to try to replace the drive, or am I hosed...

Wade Step 1. Post a syslog. Step 2. Power down, then re-seat the power connections on the drives. Odds are you have one that is loose. Power up, if some of the drives now show up, good... If not, post a syslog. Did I mention you should post a syslog? (instructions in the wiki under troubleshooting) Joe L.
April 22, 201016 yr Author Here is log... I've 4 missing 4 drives now... I think I need to do some more cable cleanup... uggg syslog-2010-04-22.txt
April 22, 201016 yr Highly likely you have a power cable that has become disconnected. Or, if they all are on the same disk controller card, it might not be seated well in the connector. Joe L.

Joe L. What's Odd is the drives that are "missing" drives are split between the Onboard SATA controller and my SuperMicro 8xPCI controller, in 2 separate 5-4 IcyDocks with completely split power I'm sure this is in the Wiki, but is there a way to plug the suspected failing/failed drive into my Ubuntu box to see if I can recover anything off of it...

Sure, each disk has a reiserfs on partition 1. They should mount easily. (all but the parity disk, it has no files, just parity bits)
April 23, 201016 yr Author OK, have no idea what I'm doing to try to mount the drive... From this Wiki page - http://lime-technology.com/wiki/index.php?title=Mounting_an_external_USB_drive_having_an_existing_NTFS_file_system_in_READ/WRITE_mode_to_transport_files_from/to_unRaid_server mount -t ntfs-3g -o umask=111,dmask=000 /dev/sdb1 /mnt/user/data/usb/ I have no idea what the /mnt thing should be and I'm getting a "does not exist" message when I execute that... The Wiki isn't very clear for NON-Linux/Unix type people like me...

The Wiki isn't very clear for NON-Linux/Unix type people like me... Basically, you mount drives on "mount-points" A mount-point is an empty directory. You can create one with any name you like. The example in the wiki worked if you had created a /mnt/user/data/usb directory to use as the mount-point. Since you are on a different server, that empty directory will not exist. You probably want to use something like /mnt/testdisk Since that directory does not exist, you can create it with mkdir /mnt/testdisk Then you can mount it with mount -t reiserfs -o umask=111,dmask=000 /dev/sdb1 /mnt/testdisk I'd also add the "ro" option to make it read only. Therefore, the command would be: mount -t reiserfs -o ro,umask=111,dmask=000 /dev/sdb1 /mnt/testdisk Joe L.

I'm having to do Sudo in front, and the previuus page said I should be using "reiserfs" instead of "ntsf-3g"... I can get it mounted, but then get a permission denied when I try to ls the /mnt, even using sudo
April 23, 201016 yr yes, you need the correct permissions. Try sudo sh Then try the "ls" once you have a root shell. You might find that your distribution is already mounting the drive for you. Check your desktop. Joe L.

Ok, using "sudo sh" I can at least LS the folders on the UnRaid drive...now I have no idea how to Copy them to the local HD... I keep trying in the GUI File Browser and it says I don't have permission

I keep trying in the GUI File Browser and it says I don't have permission Fire up a File Browser window from that "sudo sh" session, and that will start it with root permissions.
April 23, 201016 yr Author Well, after some SATA/Power wire re-routing and un/re-connecting (and replacing a couple suspect power splitters), I plugged everything back into the UNRAID, including the drive I suspected was clicking, and brought it back up. All the drives were "found" without issue. The Parity rebuild re-started and so far, no excessive "clicking" noted on any of my drives. Could have been an power cable issue and not getting enough juice or a loose wire in one of the 4pins. The Parity is running at about 13 hours so far (started at about 9pm last night) with an estimate 321+ minutes remaining...currently running @ 18,674 KB/sec, so it's chugging along, just slowly.
