I have made the mistake of booting a centos-6.8 live cd to manipulate a centos 5 system. as a result md5 has become md122, md2 has become md125, md4 has become md126, md0 has become md127, and most unfortunately md3 has also become md122. smartctl shows that the WD brand drives do support SCT mdadm --examine was used to reveal the mish-mash using uuid numbers compared with the file /etc/mdadm.conf also referencing /etc/fstab. can someone kindly tell me the mdadm command to put the correct numbers back. sda7,sdb7 (122) /dev/md5 uuid=11b7e8b7:ca181503:cf45af46:db2a5d9d / sda1,sdb1 (127) /dev/md0 uuid=d9a5774d:d930fbd8:cf45af46:db2a5d9d /boot sda3,sdb2 (125) /dev/md2 uuid=23a4116f:1d43390b:cf45af46:db2a5d9d /tmp sda5,sdb5 (122) /dev/md3 uuid=c89f6357:f1c7a0ef:cf45af46:db2a5d9d /var sda6,sdb6 (126) /dev/md4 uuid=67ad84bc:05153ebe:cf45af46:db2a5d9d /var/lib/mysql/cmdaemon_mon sda2,sdb2 ( 1) /dev/md1 uuid=5d9f0b00:24d890eb:cf45af46:db2a5d9d swap sdc1 /home much appreciated Randall Grimshaw-- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
