I get this error:

fuse-ext2: enter [do_probe (../../fuse-ext2/do_probe.c:30)]
fuse-ext2: Error while trying to open /dev/disk0s2 (rc=16) [do_probe (../../fuse-ext2/do_probe.c:34)]
fuse-ext2: Probe failed [main (../../fuse-ext2/fuse-ext2.c:337)]

Any idea why?
Thanks!

disk0s2 would be the second partition on the main hard drive. Are you sure that’s the location of your ext2 file system. When I mount a USB ext2 drive, for example, the device is /dev/disk2s1 or /dev/disk3s1

Hi,
I have the same message like Gandhi
I know why: the partition is not an ext3 partition but a Linux_LVM partition.
I look for a solution but i dont get one.
Maybe the solution could be to use commands of the lvm like vgdisplay but it doesn’t work

If you have an idea …

Thanks
(Sorry for bad english)

Hi,
In fact, it is the internal hard drive of my broken computer so I don’t want to reformat…
I hope i will get a solution with a linux OS.

Thanks

Thanks for the step by step explanation. Maybe you should add that using FUSE it is not necessary to be root (or take advantage of the sudo command) to mount an ext partition.

Eric you are fantastic, this is exactly what I was looking for!

My only question is… would you know how to get it to mount rw at boot? After installing macfuse and fuse-ext2 i can mount the drive rw using your commands in terminal perfectly, but I’d like to have it rw all the time. Right now when I load os x it shows up automatically as read only.

I’ve done some googling and I’ve poked around and I just can’t seem to figure out where fuse-ext2 gets called from in the first place to change the options to force. There aren’t many people who worked this out as quickly as you did.

Never mind! It probably isn’t the most elegant solution but it does what I want.

I wrote a little shell script and with the help of this article: http://support.apple.com/kb/HT2420?viewlocale=en_US made it work.

For anybody else who is reading this my shell script looks like this:

umount /dev/disk0s6
mkdir /Volumes/Ubuntu
/usr/local/bin/fuse-ext2 /dev/disk0s6 /Volumes/Ubuntu -o volname=Ubuntu,force

This post was the most helpful I have found for a long time. Thanks a lot!

Works like a charm! Thanks mate!

Wow, this is great I’ve been looking for a way to mount ext2/ext3 disks on MacOS X. I have backup disks attached to a Linksys NSLU2. I always worry about how I would recover the files if the server went kaput. Now I can just attach the USB drives to my Mac.

BTW, when I attached the USB drive, the Snow Leopard Finder immediately mounted the disks as read-only. So, I figured out the name of the disk (disk3s1 in this case) without using “disktool -l”. To mount the disk r/w, I ejected the disk using the Finder and mounted as above using “-o force”.

I have MAC OS X – 10.6.2 (Snow Leopard)
I installed: MacFUSE first
Then installed: fuse-ext2

See first post for details. Then I just plugged in my ext3 USB drive, powered it up and it mounted automatically in /Volumes.

This was a great surprise – No unix commands into terminal necessary.

I get:

Just installing MacFuse and fuse-ext2 I get the disks for reading only, not for writing. They are ext3, formatted with the Popcorn Hour A-110 network media tank.

Here is the errore I get when trying to mount
(before I’ve unmounted the disks with disk manager)

Thaaaanks a lot! You saved my life! =) Happy Easter!

Thanks to Eric and to Caity for the script idea. However I would point out a slight hazard:
(from bitter experience) scripting will work fine while you have only one (boot) disk,
and after you’ve finished messing about adding/subtracting disks from your system.
Diskarbitration probes asynchronously, resulting in “n” for “disknsm” being somewhat arbitrary.

Second: I’ve also struck Gnorkie’s problem, and I believe it is caused by a socket timeout.
The journaling system is different for ext3 and hfs+, thus each time a disk is remounted
on the “other” OS, the journal is rebuilt. Or maybe something else is happening?
An awful lot of disk thrashing can be heard for up to two minutes before mount fails.
Manual mount after that time is almost instant.

P’raps I should explain, I want a dual boot system, MacOS 10.6.2 + Ubuntu 9.10,
with a common shared Home on a separate volume, same disk, plus a large disk
for multimedia editing work. Home at present is a 150G partition on the common
boot disk, with ~50,000 files. It works, but… Also some people may be annoyed at
having to run a shell script every time (mount + unmount) for removable media.

Thank you very much!!!! It works perfectly with an external ext4 formatted drive.

Mark :

Same for me just loaded up MacFuse then fuse-ext2 and bingo now my server backup USB just appears on the desktop. Really. Thanks heaps to who ever was involved in creating this.

admin :
I’ve never seen that error. What did you format your drive with? I formatted my drive on an ubuntu machine with ext3 filesystem. Give me some specs on what your using and running. Let’s get this thing figured out!

I get that same exact error, like this:

fuse-ext2 /dev/disk1 /Volumes/extdrive/ -o force
fuse-ext2: version:’0.0.7′, fuse_version:’27′ [main (../../fuse-ext2/fuse-ext2.c:324)]
fuse-ext2: enter [do_probe (../../fuse-ext2/do_probe.c:30)]
fuse-ext2: Error while trying to open /dev/disk1 (rc=2133571364) [do_probe (../../fuse-ext2/do_probe.c:34)]
fuse-ext2: Probe failed [main (../../fuse-ext2/fuse-ext2.c:340)]

–

The disk is precisely the correct one (/dev/disk1) I can even hear it power on, spin up etc read it. And then the error comes.

So far I have read through about 20 forums, none of them offer any help help regarding this.

The disk is an old 40GB Ubuntu ext2 disk from around 2003 or so. From a dead laptop that died and would not power on. Some valuable data still on it, and no PC’s around to read it either..

Any help would be great – so far this problem seems to beyond the forum’s ability to solve.

very useful worked for me… thankyou

Socket is not connected…

mounting it in read-only mode (-o ro) did it =)

This was super helpful and straight-forward. Thanks!

Having some problems here.

Made a dir named NMT in Volumes, visible.
Searched for the right name and mounted the partition with the command that ends with -o ro for read only. And shabam, mounted. But I can’t write to the disk. So unmounted the disk via Finder.
Then made the dir again, and finially used the command that ends with -o force. And then nothing. The error I get after a while is:
mount_fusefs: failed to mount /Volumes/NMT@/dev/fuse0: Socket is not connected.. But when I try the exact command but thant with -o ro there’s not problem…

Somebody can help? And I’m on Snow Leopard 10.6.4.

Running 10.6.2 here. After installing macfuse and fuse-ext2, an external USB drive formatted ext4 by Linux as a single extended partition automounts read-only.

Unmounting it in the Finder, and then remounting by fuse-ext2 with the -o force option provides write access. Great!

@Gnorkie
Hey, how did you solve that? I have a A-110 and facing the same socket error when mounting in RW mode.

Thanks

I have exactly the same problem as Mark. When I plug my hard drive in, the finder recognizes it and mounts it read-only. If I unmount it with the finder, I can use fuse-ext2 command to manually mount it read-only, but if I add the “-o force” or “-o rw+” option, I eventually get the error: “mount_fusefs: failed to mount /Volumes/ext3@/dev/fuse0: Socket is not connected”

One interesting note, even after the failure is printed, the light on the hard drive continues to blink and a “ps” shows that the fuse-ext2 command is still running for a while.

I’m running 10.6.5. My disk is a 2TB ext3 formatted on centOS.

-JJ

@Douglas. NO, I didn’t solve the problem. And now I badly NEED to transfer all my files to another popcorn hard disk…….

Hello, thank you.

What am i doing wrong having this error:

failed to mount /private/tmp/usbhd@/dev/fuse1: Socket is not connected

before i had:

MacFUSE already exists and does not belong to a registered port. Unable to activate port macfuse. Use ‘port -f activate macfuse’ to force the activation.

i did it and then i installed with port install ext2fuse

But trying to mount an ext3 hd i get this error.

Dear all.

I try to install fuse-ext2 on a MacOSX 10.6.6.

when I try to

$ make

the bundle I get the following error.

$ error: There is no SDK with the name or path ‘macosx10.4′

I guess I have a newer version of SDK somewhere, but I am not sure. For sure I have Xcode.

Any idea what to change, that the installer also checks for other versions of SDK?

Thanks in advance for any help or suggestions.

Best regards

eisen

@eisen
You can download a binary (as a dmg) from http://alperakcan.org/?open=projects&project=fuse-ext2

Very nice tip. And it works. But, writing to ext3 is painfully slow. It took me 10 minutes to copy about 40 MB.

When I tried to mount an ext3 disk on a Mac OS X 10.5 after I have installed macfuse and fuse-ext2, I got :

$ mkdir /Volumes/temp
$ fuse-ext2 /dev/disk1 /Volumes/temp/
fuse-ext2: version:’0.0.7′, fuse_version:’27′ [main (../../fuse-ext2/fuse-ext2.c:324)]
fuse-ext2: enter [do_probe (../../fuse-ext2/do_probe.c:30)]
fuse-ext2: Error while trying to open /dev/disk1 (rc=16) [do_probe (../../fuse-ext2/do_probe.c:34)]
fuse-ext2: Probe failed [main (../../fuse-ext2/fuse-ext2.c:340)]

The error message is exactly the same if I used one of the partition /dev/disk1s1

Any idea?

Thanks,
Phil

Thanks for writing this, it was very helpful.

While I got my ext3 drive to mount under Snow Leopard, and I can access all the files, I do not have write access, even though I used the “-o force” option:

$ sudo ./fuse-ext2 /dev/disk1 /Volumes/Archive0 -o force
Password:
fuse-ext2: version:’0.0.7′, fuse_version:’27′ [main (../../fuse-ext2/
fuse-ext2.c:324)]
fuse-ext2: enter [do_probe (../../fuse-ext2/do_probe.c:30)]
fuse-ext2: leave [do_probe (../../fuse-ext2/do_probe.c:55)]
fuse-ext2: opts.device: /dev/disk1 [main (../../fuse-ext2/fuse-ext2.c:
351)]
fuse-ext2: opts.mnt_point: /Volumes/Archive0 [main (../../fuse-ext2/
fuse-ext2.c:352)]
fuse-ext2: opts.volname: Archive0 [main (../../fuse-ext2/fuse-ext2.c:
353)]
fuse-ext2: opts.options: force [main (../../fuse-ext2/fuse-ext2.c:
354)]
fuse-ext2: parsed_options:
force,allow_other,local,noappledouble,fsname=/dev/
disk1,fstypename=ext2,volname=Archive0 [main (../../fuse-ext2/fuse-
ext2.c:355)]
fuse-ext2: mounting read-write [main (../../fuse-ext2/fuse-ext2.c:
369)]

But when I try to write:

$ touch /Volumes/Archive0/x
touch: /Volumes/Archive0/x: Read-only file system

How can I solve this?

@Gravitas

If you can’t mount a usb external disk on mac os because the disk has an alien partition type use this procedure to mount it in mac:

1- mount the disk in linux
2- change its partition type to HPSF/NTFS with fdisk:

sudo fdisk /dev/sdb1

type ‘t’ followed by ‘enter’

if fdisk ask about which partition to change choose partition number ‘1′ always.

then type ‘7′ followed by ‘enter’ then type ‘w’ followed by ‘enter.

3- check the success of changing partition type with:
fdisk -l /dev/sdb1
The output should list the partitions as well as their types.

4- unmount the disk in linux.

5- Attache the disk to mac os and note the device id with diskutils

6- Ensure that the disk is unmount and ejected

7- Create mounting directory:

mkdir /Volumes/usb

8- Mount the disk with:

sudo mount -ar -t ntfs /dev/disk2s1 /Volumes/usb

The ‘r’ parameter means ‘read only’

If you get no error after this command, then your fine and check your disk in finder.

To everyone experiencing the “probe failed” problem Gandhi posted, or a similar probem: The solution is easy. 10:1 you tried installing the old ext2fsx program on your Mac, and it failed. Even though the installer failed, it still made changes to your system. Run the uninstall script that comes with ext2fsx and the problem will go away. More info here:

I’ve copied 40MB in 40 seconds… am trying to copy 5GB from my phone right now and it gives me an estimated time of 2 hrs. I should really have got out my old laptop which runs red hat 9 or something, but it might take 2 hrs to move all the stuff
