Nexius2 Posted January 10, 2022 Share Posted January 10, 2022 Hello, while changing some hardware, a HDD disconnected from unraid. so on next boot, it marqued it as failed. no prob, I've got 2 parity disks. obviously, turning the server off and plugging the HDD back in does not work. what I've done, unplugg the HDD, put it in a windows case and format it (ntfs) so that unraid can see it as a new HDD and do it's rebuild. but it's a fail, unraid won't event format it to it's need (and preclear doesn't want to see it). what can I do to make him rebuild my array?

itimpi Posted January 10, 2022 Share Posted January 10, 2022 You should follow the procedure documented here in the documentation accessible via the ‘Manual’ link at the bottom of the GUI which covers rebuilding a drive onto itself Quote Link to comment
Nexius2 Posted January 10, 2022 Author Share Posted January 10, 2022 thanks. following what it says, I guess I have a problem. in my array listing, it says Dsk 14 is emulated but when I check on the disk, is says there is 0 data is it because I asked it to format the HDD? why would it allow to format a emulated disk instead of the physical HDD?

If the disk is not disabled then format writes to the physical disk, but if it is disabled it writes to the emulated one. In both cases Unraid will updated parity to reflect this. When you selected the format option there is a big warning pop-up telling you this is going to happen and that format is never part of a disk recovery operation. Quote Link to comment
Nexius2 Posted January 10, 2022 Author Share Posted January 10, 2022 I couldn't guess it was the emulated disk, the option was in the array operation menu under the start array button. just like when I add any other HDD. the message just said the data was going to be erased, nothing else.
