raid5变成raid1了？
linux 是 2.4.9-e.40,lsraid看出来是这样
# lsraid -D -l -a /dev/md0
/dev/sdc1:
md version = 0.90.0
superblock uuid = 39E0464A.640EDBA9.6108B54E.0AA7F370
md minor number = 0
created = 1149251414 (Fri Jun2 20:30:14 2006)
last updated = 1149252411 (Fri Jun2 20:46:51 2006)
raid level = 5
chunk size = 32 KB
apparent disk size = 35404288 KB
disks in array = 3
required disks = 2
active disks = 2
working disks = 3
failed disks = 0
spare disks = 1
position in disk list = 0
position in md device = 0
state = good
/dev/sdd1:
md version = 0.90.0
superblock uuid = 39E0464A.640EDBA9.6108B54E.0AA7F370
md minor number = 0
created = 1149251414 (Fri Jun2 20:30:14 2006)
last updated = 1149252411 (Fri Jun2 20:46:51 2006)
raid level = 5
chunk size = 32 KB
apparent disk size = 35404288 KB
disks in array = 3
required disks = 2
active disks = 2
working disks = 3
failed disks = 0
spare disks = 1
position in disk list = 1
position in md device = 1
state = good
/dev/sde1:
md version = 0.90.0
superblock uuid = 39E0464A.640EDBA9.6108B54E.0AA7F370
md minor number = 0

raid level = 5
chunk size = 32 KB
apparent disk size = 35404288 KB
disks in array = 3

active disks = 2
working disks = 3

spare disks = 1
position in disk list = 2
position in md device = -1
state = spare
那/dev/md0应该是70G.
可是用df看出来只有33G.
# df -h
Filesystem SizeUsed Avail Use% Mounted on
/dev/sda6 8.7G3.0G5.2G37% /
/dev/sda1 197M4.9M182M 3% /boot
/dev/sda3 5.3G1.4G3.6G27% /data
/dev/sdb1 17G 12G4.1G74% /data1
/dev/sda2 17G 16G780M96% /opt
none 250M 0250M 0% /dev/shm
/dev/md0 33G734M 30G 3% /raid5
/etc/fstab如下
raiddev /dev/md0
raid-level 5
nr-raid-disks 2
nr-spare-disks 1
chunk-size 32
persistent-superblock 1
parity-algorithm left-symmetric
device /dev/sdc1
raid-disk 0
device /dev/sdd1
raid-disk 1
device /dev/sde1
spare-disk 0
我的raid5出了什么问题？
