suse 12 doesn't see my full disk space


hi experts

I have four 1TB HDD in raid 5 configuration. That means I get 3TB out of them. But when I install SUSE 12, I only see 2.73TB for dev/sda and dev/sda1 I see only 2TB.

Why is that? I am losing almost 1TB there for some reason.

I have attached a screenshot of what I see.

thanks

2 TB is the largest disk size supported by the old-style MBR disk label. For larger disk sizes you must use GPT. In addition, you must not use software such as fdisk that does not support GPT.

2.73 is due to TiB vs TB (base 2 vs base 10). 3 TB = 3000000000000 bytes = 2.728 TiB

The 2 TB partition is probably because you didn't switch the partition table over to GPT before creating sda1.

BEFORE !!!! you get to far
the VERY last opensuse 12 -- 12.3 hits End Of Life in 18 DAYS

or

is this the non free and very NEW " SUSE Enterprise Linux (Server / Desktop) 12 "

https://www.suse.com/products/server/how-to-buy/
and
https://www.suse.com/products/desktop/
https://www.suse.com/products/desktop/how-to-buy/

for the now AVERAGE large size drive 3 TB and UP
you can NOT use a dos table
use the new GPT allocation table


PS
"fdisk -l"
will not be able to read that drive

use the current Gparted live cd and reformat the drive

as above TB VS. TiB ( 1000 VS. 1024 )

the manufactures love "bleeping" people off

For pure GPT partition you need a uefi enabled system. The old BIOS has 2 terabyte limit.

It looks like / and /home are on sdb, so I don't know why you would need to reinstall the OS? What's on sda? And why are you switching to UEFI?

You can switch a disk to GPT in 5 seconds
Code:
parted /dev/sda
mklabel gpt
Then just delete and re-create the partition, again using parted or gparted, not fdisk.
