October 18, 201015 yr One of my drives started to give errors and the SMART report indicated some problems. I had already bought new drives but since the new drives were 2TB and my installed drives were 1.5TB I first needed to replace my parity drive with a larger drive. But rebuilding the parity drive would require reading data from the drive giving me errors... So to avoid losing data I needed to do a swap disable... I referred to the manual and to following threads: http://lime-technology.com/forum/index.php?topic=1479.0 http://lime-technology.com/forum/index.php?topic=1268.msg8579 However when (using the disk management page) I replaced the problem drive with the parity drive and selected a 2TB drive as the new parity drive, I got the "too many wrong disks" message and was unable to start the array. What worked for me was to: 1) To remove the problem drive from the configuration and start up the array unprotected (i.e. parity provides the data for the removed drive) 2) Shutdown the array, move the parity drive to the "failed" disk slot and add a new 2TB drive as parity. I was then able to start up the array (and it's now copying data/rebuilding parity). It may very well be that if the drive is marked as failed, the option to swap disable will be allowed but in the case such as mine where you are doing a "preemptive" replacement, it appears that the swap disable function only pops up if the drive the parity drive is replacing is first removed from the array configuration. In short if the swap disable option does not appear, try first removing the drive to be replaced from the array configuration. I didn't see this in the manual or any of the threads I could find so I thought I'd post it here - maybe it helps someone oneday. Robert
