Hi,
I created today a raid5 with three 1.5TB harddisks.
What I did:
1. created partitions on every harddisk with type 0xfd, fdisk says:
Platte /dev/sdb: 1500.3 GByte, 1500301910016 Byte
255 K?pfe, 63 Sektoren/Spuren, 182401 Zylinder
Einheiten = Zylinder von 16065 ? 512 = 8225280 Bytes
Disk identifier: 0x9e99f286
Ger?t boot. Anfang Ende Bl?cke Id System
/dev/sdb1 1 182401 1465136001 fd Linux raid
autodetect
2. Created the raid with:
mdadm --create /dev/md0 --level 5 --raid-devices 3 /dev/sd[bcd]1
cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5]
[raid4] [multipath] [faulty]
md0 : active raid5 sdd1[2] sdc1[1] sdb1[0]
2930271872 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]
Here seems everything fine.
3. Created a filesystem on the raid with:
mkfs.xfs /dev/xfs
4. Mounted the filesystem with:
mount /dev/md0 /video_test
df -h
/dev/md0 747G 5,5M 747G 1% /video_test
The raid should have a nice of 3TB and not 747GB.
Has anyone an idea what is wrong here?
TIA.
Best regards,
Matthias
