Please create raid0 + 1 !! -- Linux general technology-Linux technology and application information. For details, refer to the following section. Environment: rhel5.3 + Virtual Machine
Create a raid0 + 1 disk array !! The more detailed the better !! Thank you! 1
I have a raid0 step. Hope you can give me some advice !!
1. Add one or more hard disks (which can be easily implemented in virtual machines)
Ii. Use the fdisk command to partition the newly added Hard Disk:
Eg:
Fdisk/dev/sdb
--> N
--> P: Create a partition.
---> 1 create sdb1 partition -----> 2 create sdb2 partition ===
---> 1 enter the start slice number
------> + 1500 M input partition size, which is 1.5 GB (the same method divides sdb2 into 1.5 GB)
3. mdadm-C/dev/md0-l0-n2/dev/sdb1/dev/sdb2-a yes this 'l0' indicates raid0 'n2 'refers to 2 partitions
Iv. Format partitions in mkfs. ext3/dev/md0
5. mount/dev/md0/rhome to mount the new partition
6. mdadm-Ds>/etc/mdadm. conf
7. vim/etc/fstab modify the configuration document and configure automatic mounting upon startup
