huladaddy Posted September 13, 2022 Share Posted September 13, 2022 I have a failed disk that I need to replace. When I shut the machine down, replace the drive, then bring it back up again, can I start the array immediately? Or do I have to wait until the new drive is added? If I recall correctly, replacing a drive can take a long time as the drive is rebuilt. Quote Link to comment
JonathanM Posted September 13, 2022 Share Posted September 13, 2022 If parity was perfectly valid when the drive failed, the emulated drive is still available with all data intact and usable, albeit with a speed penalty as it needs all the remaining drives to accomplish the emulation. Rebuilding the drive can also be done while the array is up and usable. If the failed drive slot is showing unmountable, that needs to be fixed before you rebuild. Post diagnostics and don't proceed without explicit instructions if any of this doesn't make sense to you. Quote Link to comment

Thanks for the quick reply. I don't quite understand the above. The message that shows is that the "Device is disable, contents emulated", which I understand. So, if I shut down and replace the drive, can I start the array while the new drive is rebuilt. I don't know what you mean by "slot is showing unmountable". Quote Link to comment

It won't rebuild the drive until you start the array, so you have to start the array to even get the drive rebuilt. 10 hours ago, huladaddy said: don't quite understand the above. so then you should 10 hours ago, JonathanM said: Post diagnostics and don't proceed without explicit instructions if any of this doesn't make sense to you. 1 Quote Link to comment
