mdadm -Ac partitions /dev/md0 -m dev
I’m getting the message/warning that read as follows:
Failed to RUN_ARRAY /dev/md0 invalid argument.
How do I fix this issue? How do I rebuild array again on Linux operating system using mdadm command?
Can I use RAID as the only backup solution under Linux? Is RAID is reliable backup solution for server?
How can I recover from a lost software RAID device in CentOS version 4 / Debian version 3 / Red Hat Enterprise Linux 3 or 4 server system under RAID 5 software configuration?
