I have just set up amahi from the express cd.

The partitions tab says I have one partition of 229 Gb but I have 1x1Tb and 1x 250Gb disks installed. The disks are correctly listed in the disks tab.

How do I allocate the full disk space?

apparently the rest is a swap partition.

That's a pretty large partition. I guess the default partitioning does that?

Code: Select all

fdisk -l /dev/sda

(or sdb, etc.)

This is what I get:

Code: Select all

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda1            240362656 193747544  34405312  85% /
tmpfs                   250816         0    250816   0% /dev/shm

Does this mean the rest is not usable?

what's the output of

Code: Select all

root@host# fdisk -l

if you see /dev/sdb (but not /dev/sdb1) it means the system does see the disk but it lacks a partition. Create a partition and filesystem and mount it.
if you see /dev/sdb and /dev/sdb1 it means there's a partition and you can mount it like so:

Code: Select all

root@host# mkdir /mnt/test
root@host# mount /dev/sdb1 /mnt/test

if you don't see /dev/sdb at all you should check the connection between the disk and the mainboard.

Here is the output of fdisk -1

Code: Select all

Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000c786a

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1       30401   244196001   83  Linux

Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
119 heads, 55 sectors/track, 298475 cylinders
Units = cylinders of 6545 * 512 = 3351040 bytes
Disk identifier: 0xd35b417c

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1         311     1015808   82  Linux swap / Solaris

So I presume that means there is a disk recognised that needs a partition.

I thought amahi just created a single partition and recommends only 1? So should I be just increasing the size of this one?

Sorry I got that wrong. I see now that there is an sdb1 so I just need to mount it?

I'm still confused about the single partition though. Is 2 ok?

it seems your 1TB disk has been used for a swap partition
you can create an additional partition on that disk:

Code: Select all

root@host# fdisk /dev/sdb
n for new partition
p for primary
2 for the partition number
accept the defaults for the partition start and ending (<enter>, <enter>) which is by default the first available block and fills the partition up till the end
t for type
83 (= type Linux ext)
w for writing the changes to disk, you should then drop back into your shell

Once you've done all that you can create a filesystem on the partition (substitute mkfs.ext3 for your preferred flavor like ext4):

Code: Select all

root@host# mkfs.ext3 /dev/sdb2

then mount the partition where you want it (e.g. /mnt/test, substitute this with your own e.g. /var/hda/files/pictures)

Code: Select all

root@host# mount /dev/sdb2 /mnt/test

check if you can read/write on the mount point and check the mounts (just the command "mount"), the new mount should be listed.
unmount the drive; add it to /etc/fstab:

Code: Select all

root@host# cp /etc/fstab /etc/fstab.old
vi /etc/fstab
<--add the following line-->
/dev/sdb2      /mnt/test     ext3   defaults   1 2

make sure you match your own desired mount point and the filesystem type (ext3, ext4) you chose.
run "mount -a" and check that you don't get any errors.
run "mount" to see if the disk is mounted.
run "df -h" to see the available space.

enjoy!

Thanks for your help.

When I do:

Code: Select all

mkfs.ext3 /dev/sdb2

I get

Code: Select all

Could not stat /dev/sdb2 --- No such file or directory

The device apparently does not exist; did you specify it correctly?

Should I have used just sdb?

no, don't use /dev/sdb for creating a filesystem.
You first need to create a new partition (which will then automatically be called /dev/sdb2)
