JohnSnyder Posted February 22, 2017 Share Posted February 22, 2017 I downloaded the latest version of the preclear plugin. When I try to preclear a disk, I see a notification "Starting...". Twelve hours later nothing has changed. There's no disk activity, and the notification remains unchanged. What's going on? Quote Link to comment
JohnSnyder Posted February 22, 2017 Author Share Posted February 22, 2017 (edited) This link was helpful. Apparently the array has to be running in order for the preclear plugin will work - even though the disk which is being precleared is not yet in the array. The above link doesn't take you to the tutorial, so I've copied it here ... Together with simpleFeatures v1.0.11 comes a new plugin "disk preclear". This is essentially a GUI wrapper for the original preclear script written by Joe L. All credits go to Joe for his excellent piece of work. To make use of the disk preclear GUI functionality the following conditions must be met: 1. The disk is not assigned to the array 2. The array is started 3. The display setting "Display unassigned disks" is set to yes (default) Unassigned disks are displayed below the array itself and have the name +++. See the picture below. When the preclear process is running, its status and progress can be viewed in the table. Note that actions can run in parallel, that means multiple preclears can be started and can run together with a parity sync for example. The name itself is a hyperlink to the disk preclear function. And an initial settings page is shown. See the picture below. By default the execution mode "Test only" is selected. This mode performs a reading of the current disk status, without changing anything. To do a "real" preclear operation, it is required to select the appropriate execution mode. A warning message is given, and users need to acknowledge the operation to proceed - as a safety measure. Once the preclear operation is started, its progress can be followed in real-time. See the picture below. It is possible to stop a running preclear operation, but this may lead to a disk with corrupted data. You are not obliged to stay on the preclear page. The preclear operation is started in the background and keeps running when you leave the page of close the browser. Upon returning to the page, the actual status is shown. Hope this tutorial helps in working the disk preclaer plugin. BonieNL Edited February 22, 2017 by JohnSnyder Add additional information Quote Link to comment
trurl Posted February 22, 2017 Share Posted February 22, 2017 Just in case anyone gets the wrong idea from your bringing up that very old post. SimpleFeatures is incompatible with V6. Quote Link to comment
Bigdady92 Posted February 24, 2017 Share Posted February 24, 2017 I've never heard of simplefeature and I've cleared dozens of disks without having the array starting. Make sure you have all the required dependencies for preclear. Update to the latest version of applicable and worse comes to worse reboot your unraid system gracefully. Quote Link to comment
