Hello I have a problem with setting up a raid10 array with mdadm. With raidtools it runs fine, but this might be because I have been using it for a very long time. The array consists of 6 SCSI disk /dev/sd[abcdef]1 and creating and starting the raid1 is no proplem. Creating the raid0 is also no problem but starting it after it is stopped does not work. Here my /etc/mdadm.conf: DEVICE /dev/hda[2356] /dev/hde[2356] DEVICE /dev/sd[abcdef]1 ARRAY /dev/md0 level=raid1 num-devices=2 UUID=758b2a4e:74f182df:282c9a7e:0246977b ARRAY /dev/md1 level=raid1 num-devices=2 UUID=728311df:5491265a:29de2fa5:a1042914 ARRAY /dev/md2 level=raid1 num-devices=2 UUID=37bd8c5a:9e7efc91:e7537d56:b56c8eef devices=/dev/hda6,/dev/hda5,/dev/hde6,/dev/hde5,/dev/sdd1,/dev/sda1 spare-group=group1 ARRAY /dev/md3 level=raid1 num-devices=2 UUID=01bc8c7b:c3eb887e:79eb423d:bd46305f devices=/dev/sde1,/dev/sdb1 spare-group=group1 ARRAY /dev/md4 level=raid1 num-devices=2 UUID=72fe4455:cc7965b5:4fe2f4d0:2a5523ce devices=/dev/sdf1,/dev/sdc1 spare-group=group1 ARRAY /dev/md5 level=raid0 num-devices=3 UUID=c1565e2b:12c85143:d2fcffa2:12791897 devices=/dev/md2,/dev/md3,/dev/md4 Doing a "mdadm -A /dev/md5" I get: mdadm: no devices found for /dev/md5 md5 should be the raid0 consisting of the three raid1's (md2, md3, md4). What am I doing wrong?
