Hey ok I tryed to raid0 them 2TB drives into a 4tb one
Code:
mount
/dev/sda1 on / type ext4 (rw,grpquota,errors=remount-ro,usrquota)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/sdc1 on /backups type ext4 (rw)
/dev/md0p1 on /space type ext4 (rw)
I get this when using "mount"
now to me that looks right but than again am no expert
The thing is when am on my webmin page it says this
Code:
Local disk space 1.81 TB total, 289.67 GB used
and this is for all 4 drives
150gb main drive
74gb backup drive

here is the fdisk

Partition 1 does not start on physical sector boundary.
Now this is saying "Partition 1 does not start on physical sector boundary." not sure what this means but am guessing this is where the problem is
/dev/md0 doesn't have a GPT partition table, so the partition size will be limited to 2TB. You need to use parted to switch /dev/md0 to GPT, then recreate the partition and ext4 filesystem to use the full size.

Hey thanks for the reply, can I ask how I would go about doing that? also well I lose all my saved data on the drive?
There might be a way to do it without losing your data, but I would definitely back everything up first. Always a good idea before modifying the partition table.
I've never tried to do it without losing the data on the drive, so I can't help there. The following are instructions to do it while definitely wiping what's on the drive:
Code:
umount /dev/md0p1
parted /dev/md0
# use print to print the current partition table, and use rm to remove partitions until there are none left
mklabel gpt
mkpart primary ext4 0 -1
quit
If you get a warning about the partition not starting on a cylinder boundary, try
Code:
mkpart primary ext4 2048s -1
instead

Thanks leggroll, I'll back it all up just to be safe should only take a few hours ^^
I'll report back tomorrow with the results :3
Hard drives are rated in 1 TB = 1,000 GB = 1,000,000 MB = 1,000,000,000 kB = 1,000,000,000,000 B
Capacity is generally given in TiB, where 1 TiB = 1,024 GiB = 1,048,576 MiB = 1,073,741,824 kiB = 1,099,511,627,776 B
