Raid 0 + 1

[Felipe Neuwald]

Hi Folks,

I talked with my customer, and we decided to implement a 0 + 1 RAID, 
with 4 disks of 250Gb each.

Here is how my RAID is working now:

[root at fileserver /]# gvinum list
4 drives:
D a                     State: up       /dev/ad4        A: 0/238474 MB (0%)
D b                     State: up       /dev/ad5        A: 0/238475 MB (0%)
D c                     State: up       /dev/ad6        A: 0/238475 MB (0%)
D d                     State: up       /dev/ad7        A: 0/238475 MB (0%)

1 volume:
V data                  State: up       Plexes:       1 Size:        931 GB

1 plex:
P data.p0             S State: up       Subdisks:     4 Size:        931 GB

4 subdisks:
S data.p0.s0            State: up       D: a            Size:        232 GB
S data.p0.s1            State: up       D: b            Size:        232 GB
S data.p0.s2            State: up       D: c            Size:        232 GB
S data.p0.s3            State: up       D: d            Size:        232 GB


Could someone give me on example of how I'll implement a 0 + 1 RAID?

Thank you very much,

Felipe Neuwald.
