1. Disk partioning:
fdisk /dev/sda
n – create new partition
t – create partition with type RAID (fd – Linux raid autodetect)
2. Create array:
mdadm –create /dev/md[nr] –level=[0|1|etc] –raid-devices=2 /dev/sda1 /dev/sdb1
3. Format array:
mkfs.ext3 /dev/md[nr]
4. Create directory
5. Mount array
6. Add to /etc/fstab
echo „/dev/md[nr] /[katalog] defaults 0 2” >>etc/fstab
7. Create file /etc/mdadm.conf
echo „DEVICE /dev/sda1 /dev/sdb1” > /etc/mdadm.conf
mdadm –detail –scan >> /etc/mdadm.conf
mdadm –detail –scan >> /etc/mdadm.conf
General:
mdadm –add /dev/md[nr] /dev/sda2 #add disk to synchronize with array
mdadm -E /dev/sda1 #info about device inside array
cat /proc/mdstat #present state of array
mdadm –stop /dev/md[nr] #stop array, free devices
mdadm –assemble #mount arrary
mdadm –detail –scan #info about components from /proc/mdstat
mdadm -E /dev/sda1 #info about device inside array
cat /proc/mdstat #present state of array
mdadm –stop /dev/md[nr] #stop array, free devices
mdadm –assemble #mount arrary
mdadm –detail –scan #info about components from /proc/mdstat
