exporting the whole filesystem and putting it back on
 
Dear community,

I'm installing a new linux server and I've made a terrible mistake... wrong partitioning. Now my df -h output looks like this:
/dev/sda1 68G /
udev 16G /dev
tmpfs 6.3G /run
none 5.0M /run/lock
none 16G /run/shm
cgroup 16G /sys/fs/cgroup

which is unfortunate, because this OS is a hypervisor for VMs in virtualbox.
Is there a way to just back it up easily to for example NAS shared folder, make a new (single) partition and put everything back on? would it work if I just copy the files out, re-partition and copy them back in (using a live distro for example)

note: this is a 180GB ssd drive, I originally made 100gb available, but I will expand usable space to 130gb and want to use almost all of it for VMs...

Are you sure that you don't already have a single partition? None of your mounted file-systems besides /dev/sda1 is on a disk.
Please post the output of
Code:

parted -l
launched as root.

here are the partitions:
Code:

Model: LSI RAID 5/6 SAS 6G (scsi)
Disk /dev/sda: 107GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start  End    Size    Type      File system    Flags
 1      1049kB  73.1GB  73.0GB  primary  ext4            boot
 2      73.1GB  107GB  34.3GB  extended
 5      73.1GB  107GB  34.3GB  logical  linux-swap(v1)

maybe if I grab partition1 with clonezilla, save it, wipe the whole sda and create a new partition and upload the image there, it will work correctly, right?
edit: my plan is to have 130gb and no swap, I have a plenty of RAM on that one (32gb, ~20gb will be used now)

Yes, that should work.

swapoff, delete sda5, then delete sda2.
Do your backup, use gparted liveCD to expand sda1 into the freed up space.
Fix bootloader and fstab in need.

Done.

well, I would need to expand raid logical volume as well.. but I'll manage now,
thank you for hints!
