hi list! in short: I created a partitioned raid6 array with 2 missing drives. Now, I want to add a device. It fails with: flockmock ~ # mdadm -a /dev/md_d4 /dev/sdb2 mdadm: add new device failed for /dev/sdb2 as 4: Invalid argument
I think it is the same problem as in: http://marc.info/?l=linux-raid&m=115316147716600&w=2 details: kernel 2.6.20.4 mdadm-2.6.1 the raid6 array: flockmock ~ # mdadm --detail /dev/md_d4 /dev/md_d4: Version : 00.90.03 Creation Time : Sat Mar 31 19:48:58 2007 Raid Level : raid6 Array Size : 490030464 (467.33 GiB 501.79 GB) Used Dev Size : 245015232 (233.66 GiB 250.90 GB) Raid Devices : 4 Total Devices : 2 Preferred Minor : 4 Persistence : Superblock is persistent Update Time : Sat Mar 31 23:28:37 2007 State : clean, degraded Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Chunk Size : 32K UUID : dfb5e536:2447b984:b7699fd8:8ba37cbf Events : 0.2972 Number Major Minor RaidDevice State 0 8 2 0 active sync /dev/sda2 1 8 34 1 active sync /dev/sdc2 2 0 0 2 removed 3 0 0 3 removed the device, which I want to add: flockmock ~ # mdadm -E /dev/sdb2 /dev/sdb2: Magic : a92b4efc Version : 00.90.00 UUID : dfb5e536:2447b984:b7699fd8:8ba37cbf Creation Time : Sat Mar 31 19:48:58 2007 Raid Level : raid6 Used Dev Size : 245015232 (233.66 GiB 250.90 GB) Array Size : 490030464 (467.33 GiB 501.79 GB) Raid Devices : 4 Total Devices : 2 Preferred Minor : 4 Update Time : Sat Mar 31 23:29:23 2007 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 2 Spare Devices : 0 Checksum : 8aeeef56 - correct Events : 0.2974 Chunk Size : 32K Number Major Minor RaidDevice State this 4 8 18 -1 spare /dev/sdb2 0 0 8 2 0 active sync /dev/sda2 1 1 8 34 1 active sync /dev/sdc2 2 2 0 0 2 faulty removed 3 3 0 0 3 faulty removed dmesg shows such error mesgs: [ 220.681135] md: sdb2 has invalid sb, not importing!
