Great package, If I should address thios question somewhere else please let me know and sorry to bother you.
I am using the Ubuntu version and did an upgrade from Breezy to Edgy. The upgrade managed to erase the superblocks on the RAID devices I'm using. If I do a build of the array by hand
mdadm --build /dev/md0 --level=1 --raid-devices=2 /dev/hd[ac]5
mdadm --build /dev/md1 --level=1 --raid-devices=2 /dev/hd[ac]6
mdadm --build /dev/md2 --level=1 --raid-devices=2 /dev/hd[ac]7
The array seems to get built but when I do an examine it notes that the superblocks are not persistent. Thus when I do a reboot all the array will not reassemble itself. How do I fix this?
The output of: mdadm --examine /dev/md2
looks like: /dev/md2: Magic : a92b4efc Version : 00.90.00 UUID : bf0fdc1c:7831246c:cd2a4a74:fa419930 Creation Time : Sat Feb 7 13:42:02 2004 Raid Level : raid1 Raid Devices : 2 Total Devices : 2 Preferred Minor : 4 Update Time : Mon May 15 07:36:13 2006 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Checksum : 31ef920e - correct Events : 0.1577961 Number Major Minor RaidDevice State this 0 253 7 0 active sync /dev/evms/.nodes/hda7 0 0 253 7 0 active sync /dev/evms/.nodes/hda7 1 1 253 8 1 active sync /dev/evms/.nodes/hdc7
The version of mdadm reports itself as: mdadm --version mdadm - v1.12.0 - 14 June 2005
