Hi Kuai, Just to confirm, the array seems fine after the reshape. Copying files now. Would it be best if I scrap this array and create a new one or is this array safe to use in the long term? It had to use the --invalid-backup flag to get it to reshape, so there might be corruption before that resume point? I have to do a reshape anyway, to 5 raid devices. > In the meantime, I'll try to fix this deadlock, hope you don't mind a > reported-by tag. I would not, thank you. I still have the backup images of the drive in reshape. If you wish I can test any fix you create. > I have no idea why systemd-udevd is accessing the array. My guess is it is accessing this array is because it checks it for the lvm layout so it can automatically create the /dev/mapper entries. With systemd-udevd disabled, these entries to not automatically appear. And thank you again for getting me my data back. Best regards, Johan
