Having a simular issue to the one in this thread, however, slightly different, I believe. We experienced a power outage this morning. Luckily the OMV server is on battery backup, so I was able to shut the server down. Once power was restored, I restarted the server and the RAID drive is Missing. From what I can tell, during the reboot, a BIOS autorecovery setting applied GPT to 3 of my RAID drives, as seen in the blkid output below. Looking for options to recover this system. Thanks in advance for any assistance. lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 0 10.9T 0 disk └─md0 9:0 0 0B 0 raid6 sdb 8:16 0 10.9T 0 disk └─md0 9:0 0 0B 0 raid6 sdc 8:32 0 10.9T 0 disk └─md0 9:0 0 0B 0 raid6 sdd 8:48 0 10.9T 0 disk └─md0 9:0 0 0B 0 raid6 sde 8:64 0 10.9T 0 disk └─md0 9:0 0 0B 0 raid6 sdf 8:80 0 10.9T 0 disk └─md0 9:0 0 0B 0 raid6 sdg 8:96 0 10.9T 0 disk └─md0 9:0 0 0B 0 raid6 sdh 8:112 0 10.9T 0 disk sdi 8:128 0 10.9T 0 disk └─md0 9:0 0 0B 0 raid6 sdj 8:144 0 10.9T 0 disk sdk 8:160 0 10.9T 0 disk nvme0n1 259:0 0 476.9G 0 disk ├─nvme0n1p1 259:1 0 512M 0 part /boot/efi ├─nvme0n1p2 259:2 0 475.5G 0 part /var/folder2ram/var/cache/samba │ /var/folder2ram/var/lib/monit │ /var/folder2ram/var/lib/rrdcached │ /var/folder2ram/var/spool │ /var/lib/containers/storage/overlay │ /var/folder2ram/var/lib/openmediavault/rrd │ /var/folder2ram/var/tmp │ /var/folder2ram/var/log │ / └─nvme0n1p3 259:3 0 976M 0 part [SWAP] blkid /dev/sdf: UUID="cbcc5712-da6b-1419-139a-de9757c7348b" UUID_SUB="bde193d0-b68d-c1d5-11ed-5f8275a4a220" LABEL="omvnas:0" TYPE="linux_raid_member" /dev/nvme0n1p3: UUID="2bb7348b-aa0a-42a1-af4b-f4ee684c78ba" TYPE="swap" PARTUUID="d804df87-8bf9-45bd-9cb5-da32f39fee2a" /dev/nvme0n1p1: UUID="4647-262F" BLOCK_SIZE="512" TYPE="vfat" PARTUUID="8aa9ef68-1a9f-4d0e-a27b-afc72cc70946" /dev/nvme0n1p2: UUID="82bb97eb-6acc-4de0-8361-09b220ad4041" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="537d3034-7576-44ea-a8e8-ccce3d33c1b8" /dev/sdd: UUID="cbcc5712-da6b-1419-139a-de9757c7348b" UUID_SUB="3017eba0-37a3-83ff-202c-dd24668b7223" LABEL="omvnas:0" TYPE="linux_raid_member" /dev/sdb: UUID="cbcc5712-da6b-1419-139a-de9757c7348b" UUID_SUB="792c5ef1-7fb7-335c-6f63-b5a835548740" LABEL="omvnas:0" TYPE="linux_raid_member" /dev/sdi: UUID="cbcc5712-da6b-1419-139a-de9757c7348b" UUID_SUB="ee6cdfb3-c66c-013a-0918-1573a1f32bfd" LABEL="omvnas:0" TYPE="linux_raid_member" /dev/sdg: UUID="cbcc5712-da6b-1419-139a-de9757c7348b" UUID_SUB="711a8d42-424e-f6f6-9ff4-60cc2bee0cb9" LABEL="omvnas:0" TYPE="linux_raid_member" /dev/sde: UUID="cbcc5712-da6b-1419-139a-de9757c7348b" UUID_SUB="8955e286-76c7-a860-7421-928527ed2f2e" LABEL="omvnas:0" TYPE="linux_raid_member" /dev/sdc: UUID="cbcc5712-da6b-1419-139a-de9757c7348b" UUID_SUB="04f481c7-5f9f-d02b-a759-61d0b880c975" LABEL="omvnas:0" TYPE="linux_raid_member" /dev/sda: UUID="cbcc5712-da6b-1419-139a-de9757c7348b" UUID_SUB="8440a728-ed6c-82a2-bbcf-2b533cc73f22" LABEL="omvnas:0" TYPE="linux_raid_member" /dev/sdk: PTUUID="5066a101-8bc4-412b-8c31-9989f6114efe" PTTYPE="gpt" /dev/sdj: PTUUID="0543fe2c-2926-4428-a9bb-4d8478340340" PTTYPE="gpt" /dev/sdh: PTUUID="bed11372-978a-482f-8eff-9d94f18c9b61" PTTYPE="gpt" mdadm --detail /dev/md0 /dev/md0: Version : 1.2 Creation Time : Sun Sep 3 15:35:48 2023 Raid Level : raid6 Used Dev Size : 18446744073709551615 Raid Devices : 11 Total Devices : 8 Persistence : Superblock is persistent Update Time : Thu Feb 6 05:21:31 2025 State : active, FAILED, Not Started Active Devices : 8 Working Devices : 8 Failed Devices : 0 Spare Devices : 0 Layout : left-symmetric Chunk Size : 512K Consistency Policy : unknown Name : omvnas:0 (local to host omvnas) UUID : cbcc5712:da6b1419:139ade97:57c7348b Events : 260594 Number Major Minor RaidDevice State - 0 0 0 removed - 0 0 1 removed - 0 0 2 removed - 0 0 3 removed - 0 0 4 removed - 0 0 5 removed - 0 0 6 removed - 0 0 7 removed - 0 0 8 removed - 0 0 9 removed - 0 0 10 removed - 8 64 2 sync /dev/sde - 8 32 0 sync /dev/sdc - 8 0 1 sync /dev/sda - 8 80 9 sync /dev/sdf - 8 48 4 sync /dev/sdd - 8 16 3 sync /dev/sdb - 8 128 5 sync /dev/sdi - 8 96 7 sync /dev/sdg cat /etc/mdadm/mdadm.conf # This file is auto-generated by openmediavault (https://www.openmediavault.org) # WARNING: Do not edit this file, your changes will get lost. # mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. # Note, if no DEVICE line is present, then "DEVICE partitions" is assumed. # To avoid the auto-assembly of RAID devices a pattern that CAN'T match is # used if no RAID devices are configured.
