  1. I just checked the /etc/space logs and the order currently appears alphabetically there as well. So that information I found earlier doesn't prove that the disks are out of order.
  2. Wouldn't I have had to make two swaps in order to get the result below?: Number Major Minor RaidDevice State 0 8 69 0 active sync /dev/sde5 1 8 37 1 active sync /dev/sdc5 2 8 85 2 active sync /dev/sdf5 3 8 53 3 active sync /dev/sdd5 They were originally ordered c5, d5, e5, f5. If that is the case, then it wasn't the physical connection of the drives that changed things because I only unplugged one drive.
  3. So, my problem may be related to the disks being out of order. Checking /etc/space for an earlier .xml log, it shows they were in alphabetical order (sdc5, sdd5, sde5, sdf5). I tried using: syno_poweroff_task -d mdadm --stop /dev/md2 mdadm -Cf /dev/md2 -e1.2 -n4 -l5 /dev/sdc5 /dev/sdd5 /dev/sde5 /dev/sdf5 -ud97694ec:e0cb31e2:f22b36f2:86cfd4eb but it kept resulting in the error "mdadm: failed to stop array /dev/md2: Device or resource busy"
  4. Hi, I updated to DSM 6 using Jun's loader. Shortly after, I tried to add another HDD to my NAS. DSM wasn't recognizing the HDD, so I powered it off and used the SATA cables from one of the working drives to ensure it wasn't the cables. This is where everything went wrong. When DSM booted up, I saw the drive I needed, but DSM gave an error of course. After powering the unit off and swapping the cables back, it still said it needed repair, so I pressed repair in Storage Manager. Everything seemed fine. After another reboot, it said it had crashed. I let the parity check run overnight and now the RAID is running healthy as well as each individual disk, but the Volume has crashed. It's running SHR-1. I believe the mdstat results below show that it can be recovered without data loss, but I'm not sure where to go from here? Another thread added the removed '/dev/sdf2' back into active sync, but I'm not sure which letters are assigned where. /proc/mdstat/ admin@DiskStationNAS:/usr$ cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md3 : active raid1 sdc6[0] sdd6[1] 976742784 blocks super 1.2 [2/2] [UU] md2 : active raid5 sde5[0] sdd5[3] sdf5[2] sdc5[1] 8776305792 blocks super 1.2 level 5, 64k chunk, algorithm 2 [4/4] [UUUU] md1 : active raid1 sdc2[1] sdd2[2] sde2[0] sdf2[3] 2097088 blocks [12/4] [UUUU________] md0 : active raid1 sdc1[0] sdd1[1] sde1[2] sdf1[3] 2490176 blocks [12/4] [UUUU________] unused devices: <none> admin@DiskStationNAS:/usr$ mdadm --detail /dev/md2 mdadm: must be super-user to perform this action admin@DiskStationNAS:/usr$ sudo mdadm --detail /dev/md2 Password: /dev/md2: Version : 1.2 Creation Time : Sat Aug 29 05:40:53 2015 Raid Level : raid5 Array Size : 8776305792 (8369.74 GiB 8986.94 GB) Used Dev Size : 2925435264 (2789.91 GiB 2995.65 GB) Raid Devices : 4 Total Devices : 4 Persistence : Superblock is persistent Update Time : Sun Aug 27 09:38:44 2017 State : clean Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : left-symmetric Chunk Size : 64K Name : DiskStationNAS:2 (local to host DiskStationNAS) UUID : d97694ec:e0cb31e2:f22b36f2:86cfd4eb Events : 17027 Number Major Minor RaidDevice State 0 8 69 0 active sync /dev/sde5 1 8 37 1 active sync /dev/sdc5 2 8 85 2 active sync /dev/sdf5 3 8 53 3 active sync /dev/sdd5 admin@DiskStationNAS:/usr$ sudo mdadm --detail /dev/md3 /dev/md3: Version : 1.2 Creation Time : Thu Jun 8 22:33:42 2017 Raid Level : raid1 Array Size : 976742784 (931.49 GiB 1000.18 GB) Used Dev Size : 976742784 (931.49 GiB 1000.18 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Update Time : Sun Aug 27 00:07:01 2017 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Name : DiskStationNAS:3 (local to host DiskStationNAS) UUID : 4976db98:081bd234:e07be759:a005082b Events : 2 Number Major Minor RaidDevice State 0 8 38 0 active sync /dev/sdc6 1 8 54 1 active sync /dev/sdd6 admin@DiskStationNAS:/usr$ sudo mdadm --detail /dev/md1 /dev/md1: Version : 0.90 Creation Time : Sun Aug 27 00:10:09 2017 Raid Level : raid1 Array Size : 2097088 (2048.28 MiB 2147.42 MB) Used Dev Size : 2097088 (2048.28 MiB 2147.42 MB) Raid Devices : 12 Total Devices : 4 Preferred Minor : 1 Persistence : Superblock is persistent Update Time : Sun Aug 27 09:38:38 2017 State : clean, degraded Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 UUID : a56a9bcf:e721db67:060f5afc:c3279ded (local to host DiskStationNAS) Events : 0.44 Number Major Minor RaidDevice State 0 8 66 0 active sync /dev/sde2 1 8 34 1 active sync /dev/sdc2 2 8 50 2 active sync /dev/sdd2 3 8 82 3 active sync /dev/sdf2 4 0 0 4 removed 5 0 0 5 removed 6 0 0 6 removed 7 0 0 7 removed 8 0 0 8 removed 9 0 0 9 removed 10 0 0 10 removed 11 0 0 11 removed admin@DiskStationNAS:/usr$ sudo mdadm --detail /dev/md0 /dev/md0: Version : 0.90 Creation Time : Fri Dec 31 17:00:25 1999 Raid Level : raid1 Array Size : 2490176 (2.37 GiB 2.55 GB) Used Dev Size : 2490176 (2.37 GiB 2.55 GB) Raid Devices : 12 Total Devices : 4 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Sun Aug 27 10:28:58 2017 State : clean, degraded Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 UUID : 147ea3ff:bddf1774:3017a5a8:c86610be Events : 0.9139 Number Major Minor RaidDevice State 0 8 33 0 active sync /dev/sdc1 1 8 49 1 active sync /dev/sdd1 2 8 65 2 active sync /dev/sde1 3 8 81 3 active sync /dev/sdf1 4 0 0 4 removed 5 0 0 5 removed 6 0 0 6 removed 7 0 0 7 removed 8 0 0 8 removed 9 0 0 9 removed 10 0 0 10 removed 11 0 0 11 removed Hide
