April 12, 201610 yr I have a few questions about having a drive sitting as a warm standby for when there is a drive failure. 1. Can the replacement drive be smaller than the one it's replacing provided it can fit the data that was on the failed drive? I have 6TB drives mostly, but have a few good 3TB drives sitting around. Plan was to use these as a warm standby in case the 6TB ever fail. 2. What is the proper procedure for prepping the drives so I can get back up running as fast as possible when there is a drive failure? I flirted with the idea of using these drives mounted outside the array, but changed my mind. I have already used the preclear plugin to do a 2 pass preclear on them. Wondering what I need to really do to get these drives ready? 3. Where can I find a list of the proper procedure to execute a drive replacement once there is a failure?

No. The replacement process has no idea of files - it is simply working at the disk sector level and is not aware of what any sector is being used for. 2. What is the proper procedure for prepping the drives so I can get back up running as fast as possible when there is a drive failure? I flirted with the idea of using these drives mounted outside the array, but changed my mind. I have already used the preclear plugin to do a 2 pass preclear on them. Wondering what I need to really do to get these drives ready? Anything that gives you confidence that the drive is OK. Preclear is a good candidate for this but is not required when doing replacements. During replacement the whole drive gets rewritten anyway so its existing contents are irrelevant. 3. Where can I find a list of the proper procedure to execute a drive replacement once there is a failure? this is covered in the standard online documentation here
