Hi, You can only see information in sda1 etc as you are issuing the command 'mdadm -E /dev/sda1'. A better way to check the status of mdadm raid is by issuing a 'cat /proc/mdstat' that will show you the status of each raid set.
Its possible that you have corrupted one of the disks and it needs to sync. But the only way to check that is by issuing 'cat /proc/mdstat' If it does need to sync you will have to let it, depending on the size of the disk it could take a while. ** Changed in: dmraid (Ubuntu) Status: Incomplete => Invalid -- system stops booting after message JDB: barrier-based sync failed on md1-8 - disabling barriers ... wrong # of devices in RAID https://bugs.launchpad.net/bugs/598086 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
