Hello,

I am now using a 2GB usb stick, but it's almost full (debian nas takes a lot of space).

What would be the best plan to change it to a 4GB (or even 8GB) stick?

My own idea is to boot Ubuntu (or debian) Live CD on my own pc.
From their I can partition the new stick and copy the data from the old stick to the new one?

I have funplug running from usb, so it's important to make a good copy.

Thanks,

Opper

Since the nas doesn't pull a bootloader from the USB device like a PC does, it should be as simple as:

1. Plug both devices into a linux box (or use a usb hub and plug them both into the nas)
2. Use fdisk to partition the new usb device
3. Use mkfs to put the desired filesystem on the new usb device partition
4. Mount the new device
5. cp -a /olddev /newdev
6. Get a [coffee|beer|wine] while the copy finishes
7. Use the new usb device in place of the old one

that will work. but dont forget to use the same partition layout or switch to use LABEL=sth, or else the system will not find the root partition.

I would make a raw copy then extend partition.

1. cat /dev/sdc > /dev/sdd (old usb to new)
2. Extend the partion to full usb size.

thats a bad idea. you will uselessly copy sparse blocks and keep the fragmentation inside the partitions. and you also have to manually fix the partition table to the new size.

creating new partition table and partitions and then using cp -a is faster and less error prone.

I usually use rsync instead of cp to mirror directory hierarchies, even locally.

rsync is great for incremental updates, but has a lot of overhead so "cp" is significantly faster for an initial copy.
