btrfs makes old hdds appear to operate faster

[ventrical]

Ok .. it seamlessly upgraded from Quantal to Raring and that horrible "sparse error" is now gone and only 'Scanning for Btrfs...'

And now for rollback to Quantal !

[ventrical]

Here is the snapshot of the fresh Quantal Install:

root@ventrical-PY028AA-ABA-A1106N:~# apt-btrfs-snapshot supported
Supported
root@ventrical-PY028AA-ABA-A1106N:~# apt-btrfs-snapshot list
Available snapshots:
@apt-snapshot-2013-02-11_19:14:23
root@ventrical-PY028AA-ABA-A1106N:~#

Mount the btrfs filesystem to another location:

root@ventrical-PY028AA-ABA-A1106N:~# mount /dev/sda1 /mnt
root@ventrical-PY028AA-ABA-A1106N:~# ls -l /mnt/
total 0
drwxr-xr-x 1 root root 230 Feb 11 20:22 @
drwxr-xr-x 1 root root 208 Feb 11 18:06 @apt-snapshot-2013-02-11_19:14:23
drwxr-xr-x 1 root root 18 Feb 11 17:57 @home
root@ventrical-PY028AA-ABA-A1106N:~#

[ventrical]

In order to make it boot we have to rename the snapshot:

root@ventrical-PY028AA-ABA-A1106N:~# mv /mnt/@ /mnt/@_badroot
root@ventrical-PY028AA-ABA-A1106N:~# mv /mnt/@apt-snapshot-2013-02-11_19:14:23 /mnt/@
root@ventrical-PY028AA-ABA-A1106N:~#


and then .. reboot!! Here goes...

Completely wiped out everything .. even other installs.

btw .. here is ventrical - hard at work on my KVM rack totally dedicated to U+1!!

Is that a floppy disc I see before me? Alas, poor floppy I knew them well. And again so tidy a work area. Please, please promise to never set up a photo gallery of work areas. Otherwise I will have to drop out of U+1.

Great stuff ventrical.

I had to use it to flash a BIOS.

As for Btrfs and Rolling back from one distro to another?.. does not look good. I learned my lesson.

However, if one is using Btrfs for rolling back to a previous state(somewhat like Windows System Restore) then it is an excellent file system and the apt-btrfs-snapshot is an excellent tool to use. It would save a lot of time with backups.

Thanks for taking one for the team, I've been wondering if this would actually work!
