August 7, 201213 yr I have an MD1200/IDE/Sata unRAID server built for me by Lime Technology several years ago. There is one parity disk, and 11 data disks. I am using unRAID version 4.7. I am attempting to upgrade to larger, Sata disks. I first replaced parity drive and everything went smoothly. I then replaced disk 10 with a larger Sata disk and started the data rebuild process. It seemed like everything was going well, but upon returning home tonight I found the process stalled. I followed instructions in this forum to get a syslog, which I believe suggests a problem with the new parity drive? I then obtained a smartctl report for the parity drive. Unfortunately, I do not understand these logs, nor do I know how to proceed from here. Any help is greatly appreciated! Addendum: My syslog is too large to attach, even zipped (it is 16MB)! It appears that this is secondary to numerous entries about read errors for disk 0 (the parity disk). Any thoughts? smart1.txt

RMA it. There is no doubt. Joe L.
August 7, 201213 yr Author Joe L. Thank you once again for your input (you have saved me many times before)! That drive is brand new, so aggravating to RMA it! Since the data rebuild on disk 10 did not complete (87.3% and stalled), how should I proceed? If I just cancel data rebuild, stop array, and replace parity drive won't data on disk 10 be lost? I do have the original disk 10 and could use it, but not sure how to proceed. Warm regards, Frank
August 8, 201213 yr Author How about this strategy to replace parity disk without losing data on disk 10? Stop current data rebuild (moving at snail's pace due to errors on parity disk, and probably inaccurate?). Unassign disk 10 and parity disk. Power down. Reinstall original disk 10 (which has the original data and hasn't been used for anything else) and new parity replacement. Power on. Reassign disk 10, Reassign parity disk, and start parity rebuild? Any better way of doing this?

Joe, to "set a new disk configuration" is the following the method for doing that? Telnet into server, login as root, type in: initconfig

Respond to its prompt with Yes (capital "Y", lower case "es") When you refresh the web-management page afterwards, it will show ALL blue indicators for all the disks assigned.
