Synology weren't willing to help as I shrank an array, which they won't support. I don't want to minimise my chances of recovery, so I thought I'd reach out here first. The problem I am facing today is that after a reboot, all disks in the Synology are showing as 'Initialized'. It also shows there are no Disk Groups or Volumes in the system. This was not the case prior to a reboot. Prior to a reboot, a consistency check was stuck on 100.0% for a period of about 2 weeks. I'd been unable to find a solution online, but today opted to reboot for an update. Currently all of the data is inaccessible, I hope you can help me. On 7/14, the array made it's reshape and completion up to 9 drives in RAID 6. At some point, a drive failed, and a replacement drive could not be sourced within a reasonable time frame. To keep the array operating at 2-disk redundancy, on 8/1 I opted for reducing the array size to 8 disks, with the following commands: mdadm --grow /dev/md2 --array-size 35134148736 mdadm --grow -n8 /dev/md2 --backup-file /root/mdadm.md2.backup On 8/8, it was first noticed that the reshape had hung, and was stuck on 100.0% according to the synology interface (though 99% on mdadm: https://www.irccloud.com/pastebin/eonrdAHu/mdadm%20output The array continued unabated until this Tuesday (9/19) where a reboot occured, and the array didn't come back. The backup file i created, annoyingly no longer exists, as Synology wipe the root home directory on reboot. Here is the status from each individual drive (partition) that was part of the array: https://pastebin.com/Hn9PbTf3 Dan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
