need to check RAID configuration in Linux. How do you check your current software RAID configuration in a Linux-based server powered by RHEL/CentOS or Debian/Ubuntu Linux?
am moving a raid array called /dev/md0 from serverA to serverB. On serverB /dev/md0 is already in use. How do I rename a RAID array from /dev/md0 to /dev/md2?
Recently, I’ve added another 73GB SAS disk to my Linux server after the installation. I’ve 30GB empty partition on old hard disk. How do I convert old /dev/sda3 and new /dev/sdb1 (both 30GB) into RAID 1 to improve NFS server speed and reliability?
How do I create Software RAID 1 arrays on Linux systems without using GUI tools or installer options? How do I setup RAID 1 array under Linux systems?
hen I run the following command at shell prompt on Debian or Ubuntu Linux
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?
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?
