FSArchiver is reporting an ext4 partition as "unknown type"

Post by msx » Sat Jan 05, 2013 10:43 pm

Edit: [SOLVED, WON'T FIX] as for Sat 05, January 2013 this is a standing issue, that's why I mark this post this way.

Hello all, first post here of a long-time FSArchiver user (thanks for this awesome tool!)

After setting up a home server and checking out that everything is working as expected I want to make sure I have a working backup of it to cover my back in the event something -anything- goes wrong, I expended a considerable time setting it up and I don't go to pass through all that hassle again!

So as the server will go headless -managed via ssh and X2Go- I'm checking out that live backup works as expected. For this I tried the following command:

# fsarchiver -dv -j5 -z6 -A savefs SYSBAK/2013-01-05_root /dev/sda1

which should work fine but alas FSArchiver kicks my butt with this error message:
"Creating logfile in /var/log/fsarchiver_2013-01-05_19-13-38_24324.log
Running fsarchiver version=[0.6.15], fileformat=[FsArCh_002]
oper_save.c#947,filesystem_mount_partition(): filesystem of partition [/dev/sda1] is not supported by fsarchiver: filesystem=[1]
removed SYSBAK/2013-01-05_root.fsa"

something totally unexpected since I manually did all the server's partitioning layout!
In the hope to get a better understanding of what can be making FSArchiver fail to recognize the partition filesystem I order it to probe the system:

Code: Select all

[arrakis] j:0 /home # fsarchiver -dv probe

As expected this shows up that /dev/sda1 partition fs is indeed ext4.

My very question is: is there any way to force FSArchiver to treat a partition as a specific file system - for example by forcing it to ignore/bypass fs type check?

Any idea will be greatly appreciated!

Re: FSArchiver is reporting an ext4 partition as "unknown ty

Oops, it seems my enquire is already answered: http://www.fsarchiver.org/forums/viewto ... =14&t=1374

Since I too am running Arch Linux x86_64 with latest systemd (196) and latest FSArchiver64 version 0.6.15 (2012-06-02) this seems an incompatibility between FSArchiver64 and systemd 196.

It isn't so strange now why I never got before any error message like this when I use FSArchiver from SysRescCD to do regular backup jobs on my machines.
As systemd is my main and only PID1 handler I'm unable to boot outside it so it seems I will need to attach a monitor to my server and do a backup the traditional way; I hope we have better integration systemd <-> FSArchiver soon!

Many thanks,
Martin
