I used to have a 5-disk RAID5 partition, all working very well. I have then decided to add 3 more disks on it, totaling 8 equal disks. I've opened Webmin and just asked to add the disks.
Then I've realized the three disks had NTFS partitions, wich mdadm didn't complain, so I tried to stop the growing to remove the Windows partitions. I've tried to remove a disk using the same Webmin, but (as you might guess and call me fool...), the system became unstable.
By restarting the system, I've started receiving these messages:
"udev: timeout: killing '/sbin/mdadm --incremental /dev/sdh1' "
"udev: timeout: killing '/sbin/mdadm --detail --export /dev/md0' "
I've formated the system disk, hoping to get a system up and running. I did that with all RAID disks disconected, so everything was fine. I then reconnected the disks, wich was also ok. And finally installed mdadm using apt-get.
By reboot, the system has found the mdadm intention of growing the system, so the same messages appear again.
I other words: I can't even reach a command prompt to do something.
Any ideas of what to do? I believe I could turn off the system, disconnect the disks and look for the mdadm.conf file. Would that be a good idead? I'm no Linux expert, so I'm really lost here.
