Hi, i have a NAS blackarmor 440 server. I have installed Debian on it using http://forums.seagate.com/t5/BlackAr...NAS/td-p/79422
this guide...

I have very litle space left, and need to resize the root partition. I have been trying to look for some guides, but often it says, boot into livecd.. I can't to that. As i have no screen to the NAS server.

this is my fdisk -l

Code:

And this is my df -h

Code:

/dev/md2              494M   24M  445M   5% /mnt/md2

It seems like its a LVM disk, but i am not sure. Would anyone please tell me what to do?

Thanks for the help..

Can't tell if LVM is in use. Can you use parted to list the partitions instead?

Ok, so looks like no LVM.

The only way you can do this is if / is not mounted. The only way to do that is to boot it off of something other than then hard drive, such as a live CD.

Okei, i see.

Would I be able to take out the hardrive and put it into a second computer and boot it from a livecd?
And make the / bigger without any loose of data? I would hope that I could boot from the same computer later... And if so, how?
