Greets, I currently try to setup a md-device containing of 4 partitions |
| 2 |
on 4 SATA-drives: |

I want a RAID5-device md2 (without hotspare, while md1 *has* a |
| 40 |
hotspare-partition) containing the partitions "sd?4". |
| 41 |
|
| 42 |
I have now: |
| 43 |
|
| 44 |
cat /proc/mdstat |
| 45 |
Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] |
| 46 |
md1 : active raid5 sdd3[3](S) sdc3[2] sdb3[1] sda3[0] |
| 47 |
17591040 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU] |
| 48 |
|
| 49 |
md2 : active raid5 sdd4[3] sdc4[2] sdb4[1] sda4[0] |
| 50 |
2903386944 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU] |
| 51 |
|
| 52 |
md0 : active raid1 sdb1[1] sda1[0] |
| 53 |
15936 blocks [2/2] [UU] |
| 54 |
|
| 55 |
|
| 56 |
md2 is the one that gives me headaches. AFAI understand it should be |
| 57 |
about 3TB in size, but it is only 774 GB .... |
| 58 |
|
| 59 |
# fdisk -l /dev/md2 |
| 60 |
|
| 61 |
Platte /dev/md2: 774.0 GByte, 774044975104 Byte |
| 62 |
2 Köpfe, 4 Sektoren/Spuren, 188975824 Zylinder |
| 63 |
Einheiten = Zylinder von 8 × 512 = 4096 Bytes |
| 64 |
Disk identifier: 0x00000000 |
| 65 |
|
| 66 |
|
| 67 |
Why? |
| 68 |
|
| 69 |
# cat /proc/version |
| 70 |
Linux version 2.6.25-gentoo-r8 (root@horde) (gcc version 4.1.2 (Gentoo |
| 71 |
4.1.2 p1.1)) #2 SMP Wed Oct 22 11:07:19 CEST 2008 |
| 72 |
|
| 73 |
Maybe anything wrong in my kernel? |
| 74 |
|
| 75 |
I also noticed that only 1G RAM of 2 had been detected as I had no |
| 76 |
SMP-support in the previous kernel ... now I have ... |
| 77 |
|
| 78 |
Thanks for any pointer .... |
