Greets, I currently try to setup a md-device containing of 4 partitions
on 4 SATA-drives:
# fdisk -l | grep "sd"
Platte /dev/sda: 1000.2 GByte, 1000204886016 Byte
/dev/sda1 1 2 16033+ fd Linux raid

I want a RAID5-device md2 (without hotspare, while md1 *has* a
hotspare-partition) containing the partitions "sd?4".
I have now:
cat /proc/mdstat
Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md1 : active raid5 sdd3[3](S) sdc3[2] sdb3[1] sda3[0]
17591040 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]
md2 : active raid5 sdd4[3] sdc4[2] sdb4[1] sda4[0]
2903386944 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU]
md0 : active raid1 sdb1[1] sda1[0]
15936 blocks [2/2] [UU]
md2 is the one that gives me headaches. AFAI understand it should be
about 3TB in size, but it is only 774 GB ....
# fdisk -l /dev/md2
Platte /dev/md2: 774.0 GByte, 774044975104 Byte
2 Köpfe, 4 Sektoren/Spuren, 188975824 Zylinder
Einheiten = Zylinder von 8 × 512 = 4096 Bytes
Disk identifier: 0x00000000
Why?
# cat /proc/version
Linux version 2.6.25-gentoo-r8 ([EMAIL PROTECTED]) (gcc version 4.1.2 (Gentoo
4.1.2 p1.1)) #2 SMP Wed Oct 22 11:07:19 CEST 2008
Maybe anything wrong in my kernel?
I also noticed that only 1G RAM of 2 had been detected as I had no
SMP-support in the previous kernel ... now I have ...
Thanks for any pointer ....
Stefan
