February 3, 201214 yr I have had the misfortune of having 2 disks fail while on vacation. 1 Disk is clearly pooched judged by the clicking sound it makes and my inability to view it connected to another computer. The 2nd Disk however can be opened and viewed (using a reiserfs viewer on a windows PC). I am making a backup of the contents of this drive just in case. No writing will have been done to the array in my absence, so I am wondering if there is any chance to recover my array by 1) re-enabling the 2nd drive in the array (I trust its contents, at least until step 2 is complete) 2) rebuilding the first drive with a new one following step 1 Array specifics: - 16 drive array (full with 1 and 2 TB drives) - Unraid version 4.4.2 - apologies, rebooted, so no syslog available thx in advance for help!

Yes, you should be able to accomplish what you are thinking. You'll need to set a new initial disk configuration, AND also set the invalid slot to the disk to be rebuilt (disk1) instead of the parity disk (disk0) BEFORE starting the array. If you have no idea what I'm talking about, time to do some searching AND ask specific questions before you proceed. Joe L.
February 9, 201214 yr I'm running Pro 5.0-beta6a, so if necessary please move this post.... However! I'm having basically the same issue - I was out of town for a week, came home to a very loud (and very dead) clicking drive and another drive marked as disabled. I mounted the disabled drive (read-only) and poked around the seemingly-fine filesystem, but otherwise I haven't modified any of the other array drives. I've pulled the dead drive and precleared a new drive as its replacement. I'd like to try the same procedure as the OP - trusting the disabled drive, keeping my other drives and parity, then rebuilding onto the new precleared drive (then crossing my fingers and hoping for limited corruption) I looked at a few threads that used initconfig and the Trust My Array procedure, but before continuing I'd like clearer instructions so that I don't destroy my parity. Any help would be greatly appreciated. Thank you in advance!
February 26, 201214 yr Author Okay, have had a look through the posts and am still not comletely sure what I need to do to make this work. - I am on version 4.4.2 - I have a 16 drive system. Mostly 2 TB drives, and very full. So am suitably nervous about screwing this up. - Disk 1 has absolutely failed - System has disabled disk 4 but I have reviewed its contents and am comfortable with it I can see how I can unassign and re-assign the Drive 1 to start a pariy rebuild of it, but I'm not sure how I make the system believe that Drive 4 is okay before I do this. Any help would be appreciated. Thx!
