Dear all, I’m new to this mailing list and not actually knowledgeable with RAID except for what I learned from the WIKI. I currently have a crashed RAID6 volume on a Synology DS413j that I’d like to rescue. The volume crashed due to a power failure while shutting down the DiskStation. The original RAID had one 4 TB (/dev/sda) and three 8 TB disks (/dev/sd[bcd] assembled in a RAID6 array. Now, after the crash only disk 4 (/dev/sdd3) appears to be still active, sd[abc]3 show up as “removed”. The disks are almost new and I believe they are fine (no bad blocks, etc). Re-assembling the RAID failed. So, in order to not touch the original disks, I dd-cloned two of the drives (sdc and sdd), put them into a Synology DS414play as sda and sdb and re-created the RAID with mdadm -C /dev/md2 -R -l6 -e 1.2 -n4 missing missing /dev/sda3 /dev/sdb3 --assume-clean which created a new, degraded RAID6 (/dev/md2) that I hoped would bring me my data back. Unfortunately, I still cannot mount the volume. Synology disk station says “There is no volume in your system”. Mount complains that it cannot read the superblock (see output below). Any idea how I could rescue the data and/or get the lost volume mounted is highly appreciated. Thanks in advance. Best regards, CygX1 Below are a couple of outputs from the following commands I got with the cloned, re-created, degraded RAID: cat /proc/mdstat mke2fs -n /dev/md2 blkid smartctl --xall /dev/sda smartctl --xall /dev/sdb mdadm --examine /dev/sda mdadm --examine /dev/sdb mdadm --examine /dev/sda1 mdadm --examine /dev/sda2 mdadm --examine /dev/sda3 mdadm --examine /dev/sdb1 mdadm --examine /dev/sdb2 mdadm --examine /dev/sdb3 mdadm --detail /dev/md2 fdisk -l fsck.ext4 /dev/md2 mount /dev/md2/volume1 #--------------------------------------------------- cat /proc/mdstat #--------------------------------------------------- Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md2 : active raid6 sda3[2] sdb3[3] 15618348032 blocks super 1.2 level 6, 512k chunk, algorithm 2 [4/2] [__UU] bitmap: 0/59 pages [0KB], 65536KB chunk md1 : active raid1 sda2[3] sdb2[2] 2097088 blocks [4/2] [__UU] md0 : active raid1 sda1[0] sdb1[2] 2490176 blocks [4/2] [U_U_] unused devices: <none #--------------------------------------------------- mke2fs -n /dev/md2 #--------------------------------------------------- Filesystem label=1.42.6-23824 OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=128 blocks, Stripe width=256 blocks 488075264 inodes, 3904587008 blocks 25600 blocks (0.00%) reserved for the super user First data block=0 Maximum filesystem blocks=4294967296 119159 block groups 32768 blocks per group, 32768 fragments per group 4096 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 102400000, 214990848, 512000000, 550731776, 644972544, 1934917632, 2560000000, 3855122432 #--------------------------------------------------- blkid #--------------------------------------------------- /dev/sda1: UUID="9b9510c8-2f5f-ba84-e8f7-cd2cfc4aa1f2" TYPE="linux_raid_member" PARTUUID="b8dd8450-4bee-4f8e-bf70-5fc4f9facab8" /dev/sda2: UUID="1267e84d-922a-1ce1-77a5-e2d4aab78efd" TYPE="linux_raid_member" PARTUUID="55b03321-9bd7-48ab-9930-f9428bad95d3" /dev/sda3: UUID="d013aa01-660b-4b6b-fbf8-da9169e8e5f3" UUID_SUB="9322eb7c-571b-2fe1-bb65-bfc658fbfd06" LABEL="sabayon:2" TYPE="linux_raid_member" PARTUUID="3ce7f588-49a6-4a8a-a203-2d1e83cf8a97" /dev/sdb1: UUID="9b9510c8-2f5f-ba84-e8f7-cd2cfc4aa1f2" TYPE="linux_raid_member" PARTUUID="676a76fc-9729-4089-958d-70b506ebde42" /dev/sdb2: UUID="1267e84d-922a-1ce1-77a5-e2d4aab78efd" TYPE="linux_raid_member" PARTUUID="d02355e0-9b6d-4f97-8831-9f6d1e46b669" /dev/sdb3: UUID="d013aa01-660b-4b6b-fbf8-da9169e8e5f3" UUID_SUB="89a56d24-3505-61f8-aaf0-301685c6c29d" LABEL="sabayon:2" TYPE="linux_raid_member" PARTUUID="db1a4fa7-8396-4b65-9997-3ce3a5b2d1fd" /dev/md0: LABEL="1.42.6-5967" UUID="9488e27a-0e11-4449-9a50-fc6896b1e4df" TYPE="ext4" /dev/md1: UUID="0985a469-acce-4700-adb5-c2aded0c5c45" TYPE="swap" /dev/zram0: UUID="13f547ec-5a31-4602-9bc7-6bfdc9671b8a" TYPE="swap" /dev/zram1: UUID="80006933-44af-4c4d-8d15-8891911784b8" TYPE="swap" /dev/synoboot1: SEC_TYPE="msdos" UUID="10EE-589C" TYPE="vfat" PARTLABEL="EFI System" PARTUUID="6103b609-6b34-4b6c-a5fd-ba906410e3ab" /dev/synoboot2: UUID="45e5b07d-4783-4867-a369-f99c0cd1e610" TYPE="ext2" PARTLABEL="Linux filesystem" PARTUUID="174c3fe7-929a-47d3-912d-301bd98da021" #--------------------------------------------------- smartctl --xall /dev/sda #--------------------------------------------------- smartctl 6.5 (build date Sep 4 2018) [x86_64-linux-4.4.59+] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Seagate IronWolf Device Model: ST8000VN0022-2EL112 Serial Number: ZA1C0RCJ LU WWN Device Id: 5 000c50 0b18c7abb Firmware Version: SC61 User Capacity: 8,001,563,222,016 bytes [8.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 7200 rpm Form Factor: 3.5 inches Device is: In smartctl database [for details use: -P show] ATA Version is: ACS-3 T13/2161-D revision 5 SATA Version is: SATA 3.1, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Tue Oct 23 19:43:27 2018 CEST SMART support is: Available - device has SMART capability.
