digitalfixer Posted February 23, 2018 Posted February 23, 2018 Is it my imagination or can I now just replace a drive without preclearing first. No spare ports or space. I've read through various release notes but not found the answer. Kevin.

digitalfixer Posted February 23, 2018 Author Posted February 23, 2018 So if I've got this right, I stop the array, Unassign the drive I want to remove, Power down and replace the old drive with a new drive (straight out of the box.) Power up and assign the new drive in place of the old, Start the array and let it rebuild the new drive. And the server is still useable while this is being done. Kevin

Kevin I think you may have to first start the array with the drive Unassigned to simulate a failure and get unRAID to forget the serial of the old drive, but otherwise the steps look correct.

Frank1940 Posted February 23, 2018 Posted February 23, 2018 If you use this method, I would do a parity check thee-to-seven days later just to make sure that everything is still OK. (99+% pf the time it will be but you always want to catch the odd chance that the new HD is a victim of infant mortality.)

No need, simply shutdown the system, replace the drive, start the system and assign the new drive, then start the array.
digitalfixer Posted February 26, 2018 Author Posted February 26, 2018 Just one question before I start this. Will the content of the disk I'm replacing still be available for reading only via emulation during the rebuild of the new drive. Kevin.
JorgeB Posted February 26, 2018 Posted February 26, 2018 It will be available for read/write, though for performance reasons you should avoid heavy activity during the rebuild.
digitalfixer Posted February 26, 2018 Author Posted February 26, 2018 Thanks to all who replied. Getting started now. Kevin.
