I have some info related to the array in question: 115 /dev/md2: 116 Version : 0.90 117 Creation Time : Mon Feb 11 07:54:36 2013 118 Raid Level : raid5 119 Array Size : 511999872 (488.28 GiB 524.29 GB) 120 Used Dev Size : 255999936 (244.14 GiB 262.14 GB) 121 Raid Devices : 3 122 Total Devices : 3 123 Preferred Minor : 2 124 Persistence : Superblock is persistent 125 126 Update Time : Sun Mar 22 18:23:38 2015 127 State : clean 128 Active Devices : 3 129 Working Devices : 3 130 Failed Devices : 0 131 Spare Devices : 0 132 133 Layout : left-symmetric 134 Chunk Size : 64K 135 136 UUID : 2cff15d1:e411447b:fd5d4721:03e44022 (local to host lamachine) 137 Events : 0.478 138 139 Number Major Minor RaidDevice State 140 0 8 3 0 active sync /dev/sda3 141 1 8 18 1 active sync /dev/sdb2 142 2 8 34 2 active sync /dev/sdc2 I haven't taken any actions to try to re-assemble the array and wanted to check for ideas/suggestions here first.

You may have had some device names reordered. Building a config that relies on the names is common but unwise. With such a thin report, there's not much to go on. Please run lsdrv [1] and paste its output in a reply. Then add the contents of /proc/mdstat, the relevant-looking parts of dmesg, and your mdadm.conf file. We may need more later, but this will permit intelligent follow-up questions. Phil [1] https://github.com/pturmel/lsdrv ^ permalink raw reply [flat|nested] 5+ messages in thread

Your array didn't assemble because mdadm.conf said not to. The AUTO clause is excluding unidentified v0.90 metadata. The UUID ....:bc810f04 was called out explicitly, so it assembled. You should be safe to just assemble the array normally: mdadm -A /dev/md2 /dev/sd{a3,b2,c2} Then you need to create a new mdadm.conf. I suggest you use "AUTO -all" and explicitly list all of your arrays. You only need the device name and the UUID on each ARRAY line. You can run "mdadm -Es >>..../mdadm.conf" to add live arrays to the file, then trim out the unnecessary details. When mdadm.conf has your arrays, with the names you want them to keep, update your initramfs. (Command varies by distro.)
