Hello,
How does one configure gvinum for RAID 5+0 (distributed parity nested in
stripe)? The configuration I've tried seems to be incorrect.
Config:
drive a device /dev/ad10
drive b device /dev/ad12
drive c device /dev/ad14
drive d device /dev/ad4
drive e device /dev/ad6
drive f device /dev/ad8
volume storage
plex org striped 512k
plex org raid5 512k
sd length 953869m drive a
sd length 953869m drive b
sd length 953869m drive c
plex org raid5 512k
sd length 953869m drive d
sd length 953869m drive e
sd length 953869m drive f
What gvinum creates:
6 drives:
D f State: up /dev/ad8 A: 0/953869 MB (0%)
D e State: up /dev/ad6 A: 0/953869 MB (0%)
D d State: up /dev/ad4 A: 0/953869 MB (0%)
D c State: up /dev/ad14 A: 0/953869 MB (0%)
D b State: up /dev/ad12 A: 0/953869 MB (0%)
D a State: up /dev/ad10 A: 0/953869 MB (0%)
1 volume:
V storage State: up Plexes: 3 Size: 1863 GB
3 plexes:
P storage.p2 R5 State: up Subdisks: 3 Size: 1863 GB
P storage.p1 R5 State: up Subdisks: 3 Size: 1863 GB
P storage.p0 S State: down Subdisks: 0 Size:
0 B
6 subdisks:
S storage.p2.s2 State: up D: f Size: 931 GB
S storage.p2.s1 State: up D: e Size: 931 GB
S storage.p2.s0 State: up D: d Size: 931 GB
S storage.p1.s2 State: up D: c Size: 931 GB
S storage.p1.s1 State: up D: b Size: 931 GB
S storage.p1.s0 State: up D: a Size: 931 GB
Thanks,
