Cpz Posted May 21, 2021 Share Posted May 21, 2021 hi all. I recently updated my Kurnel and rebooted my Helios64. when it loaded in to OMV i noticed my raid drive is missing. i can still see the disks just not the raid drive . Checking on the array i can see it failed with an error 524. Would love some suggestions on how to repair the array. below is the details i was able to get,.. sorry for the large info dump root@helios64:~# mdadm --run /dev/md0 mdadm: failed to start array /dev/md0: Unknown error 524 root@helios64:~# mdadm -D /dev/md0 /dev/md0: Version : 1.2 Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Total Devices : 4 Persistence : Superblock is persistent Update Time : Mon Dec 14 16:49:07 2020 State : active, FAILED, Not Started Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Chunk Size : 512K Consistency Policy : unknown Name : helios64:Home (local to host helios64) UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Events : 0 Number Major Minor RaidDevice State - 0 0 0 removed - 0 0 1 removed - 0 0 2 removed - 0 0 3 removed - 8 32 0 sync /dev/sdc - 8 0 2 sync /dev/sda - 8 48 1 sync /dev/sdd - 8 16 3 sync /dev/sdb root@helios64:~# ^C root@helios64:~# cat /proc/mdstat Personalities : [raid0] [linear] [multipath] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : inactive sdd[1] sdc[0] sdb[3] sda[2] 19534553088 blocks super 1.2 unused devices: <none> root@helios64:~# mdadm --examine /dev/sd[abcde] /dev/sda: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Name : helios64:Home (local to host helios64) Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Avail Dev Size : 11720780976 (5588.90 GiB 6001.04 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=264112 sectors, after=0 sectors State : clean Device UUID : 4efe5ed4:e612db01:c827abcf:30cf9d60 Update Time : Mon Dec 14 16:49:07 2020 Bad Block Log : 512 entries available at offset 8 sectors Checksum : 403cbc68 - correct Events : 0 Chunk Size : 512K Device Role : Active device 2 Array State : AAAA ('A' == active, '.' == missing, 'R' == replacing) /dev/sdb: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Name : helios64:Home (local to host helios64) Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Avail Dev Size : 11720780976 (5588.90 GiB 6001.04 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=264112 sectors, after=0 sectors State : clean Device UUID : 2fa13dfd:7e1c90cc:e086e232:a2f84f2a Update Time : Mon Dec 14 16:49:07 2020 Bad Block Log : 512 entries available at offset 8 sectors Checksum : 60b9f16c - correct Events : 0 Chunk Size : 512K Device Role : Active device 3 Array State : AAAA ('A' == active, '.' == missing, 'R' == replacing) /dev/sdc: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Name : helios64:Home (local to host helios64) Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Avail Dev Size : 7813772976 (3725.90 GiB 4000.65 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=264112 sectors, after=0 sectors State : clean Device UUID : 4cee06fa:a32a5035:df544d4a:9a37139a Update Time : Mon Dec 14 16:49:07 2020 Bad Block Log : 512 entries available at offset 8 sectors Checksum : 649123a1 - correct Events : 0 Chunk Size : 512K Device Role : Active device 0 Array State : AAAA ('A' == active, '.' == missing, 'R' == replacing) /dev/sdd: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Name : helios64:Home (local to host helios64) Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Avail Dev Size : 7813772976 (3725.90 GiB 4000.65 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=264112 sectors, after=0 sectors State : clean Device UUID : 52c35a71:983beb7b:eeae2343:83e9fa0f Update Time : Mon Dec 14 16:49:07 2020 Bad Block Log : 512 entries available at offset 8 sectors Checksum : 913e1594 - correct Events : 0 Chunk Size : 512K Device Role : Active device 1 Array State : AAAA ('A' == active, '.' == missing, 'R' == replacing) root@helios64:~# mdadm --stop /dev/md0 mdadm: stopped /dev/md0 root@helios64:~# mdadm /dev/md0 --assemble /dev/sd[abcde] mdadm: failed to RUN_ARRAY /dev/md0: Unknown error 524 root@helios64:~# mdadm /dev/md0 --assemble --force /dev/sd[abcde] mdadm: /dev/sda is busy - skipping mdadm: /dev/sdb is busy - skipping mdadm: /dev/sdc is busy - skipping mdadm: /dev/sdd is busy - skipping root@helios64:~# 0 Quote Link to comment Share on other sites More sharing options...
