Package: mdadm Version: 2.6.7-3 Severity: important Hello,
I played recently around with the Linux software RAID for grub2, I had never before that much to do with it so maybe I did something wrong. But in any case it shouldn't be that easy to get a broken RAID 10 :) It's more from my memory and .bash_history now, I didn't do it now exactly that way again. I made a 4 disk RAID 10 with: # mdadm -C -l10 -n4 /dev/md0 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 Then I just set one after one faulty and removed them and then added it back again. # mdadm -f /dev/sdc1 # mdadm -r /dev/sdc1 # mdadm -a /dev/sdc1 Before I stopped it I luckly did a -Q --detail see below I can't reassemble it now: mdadm: /dev/md0 assembled from 1 drive and 3 spares - not enough to start the array. I even tried before stopping the RAID, a --update=resync but that didn't change anything. mdadm --grow -n4 didn't work either, unfortunately I don't have the output anymore. # mdadm -Q --detail /dev/md0 /dev/md0: Version : 00.90 Creation Time : Mon Aug 18 18:17:19 2008 Raid Level : raid10 Array Size : 16771584 (15.99 GiB 17.17 GB) Used Dev Size : 8385792 (8.00 GiB 8.59 GB) Raid Devices : 4 Total Devices : 4 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Mon Aug 18 20:13:58 2008 State : clean, degraded Active Devices : 1 Working Devices : 4 Failed Devices : 0 Spare Devices : 3 Layout : near=2, far=1 Chunk Size : 64K UUID : 2b2e94e0:ec27865c:89ccbef7:ff5abfb0 (local to host fz-vm) Events : 0.448 Number Major Minor RaidDevice State 0 0 0 0 removed 1 8 49 1 active sync /dev/sdd1 2 0 0 2 removed 3 0 0 3 removed 4 8 81 - spare /dev/sdf1 5 8 65 - spare /dev/sde1 6 8 33 - spare /dev/sdc1 -- Package-specific info: --- mount output /dev/sda1 on / type ext4dev (rw,errors=remount-ro) tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) /proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) udev on /dev type tmpfs (rw,mode=0755) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620) fusectl on /sys/fs/fuse/connections type fusectl (rw) [EMAIL PROTECTED]:/home/fz on /home/fz type fuse.sshfs (rw,nosuid,nodev,max_read=65536,allow_other) --- mdadm.conf # 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.
