Hi, |
2 |
|
3 |
I created today a raid5 with three 1.5TB harddisks. |
4 |
What I did: |
5 |
1. created partitions on every harddisk with type 0xfd, fdisk says: |
6 |
Platte /dev/sdb: 1500.3 GByte, 1500301910016 Byte |
7 |
255 K?pfe, 63 Sektoren/Spuren, 182401 Zylinder |
8 |
Einheiten = Zylinder von 16065 ? 512 = 8225280 Bytes |
9 |
Disk identifier: 0x9e99f286 |
10 |
|
11 |
Ger?t boot. Anfang Ende Bl?cke Id System |
12 |
/dev/sdb1 1 182401 1465136001 fd Linux raid |
13 |
autodetect |
14 |
|
15 |
2. Created the raid with: |
16 |
mdadm --create /dev/md0 --level 5 --raid-devices 3 /dev/sd[bcd]1 |
17 |
|
18 |
cat /proc/mdstat |
19 |
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] |
20 |
[raid4] [multipath] [faulty] |
21 |
md0 : active raid5 sdd1[2] sdc1[1] sdb1[0] |
22 |
2930271872 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU] |
23 |
|
24 |
Here seems everything fine. |
25 |
|
26 |
3. Created a filesystem on the raid with: |
27 |
mkfs.xfs /dev/xfs |
28 |
|
29 |
4. Mounted the filesystem with: |
30 |
mount /dev/md0 /video_test |
31 |
df -h |
32 |
/dev/md0 747G 5,5M 747G 1% /video_test |
33 |
|
34 |
The raid should have a nice of 3TB and not 747GB. |
35 |
Has anyone an idea what is wrong here? |
36 |
|
37 |
TIA. |
38 |
|

Best regards, |
