[SOLVED - FreeBSD] cannot mount ext4 partition - berk - 03-07-2013
I have a 238.4 GB SAMSUNG HD251HJ ATA-7 SATA2 hard disk which I used as a home partition for my Linux installation. Yesterday I migrated to FreeBSD and I have not been able to recover my data since. I have tried to mount the filesystem, but I keep getting an error. Here's a transcript of my terminal session:
Code:
$ gpart show
=> 34 156301421 ada0 GPT (74G)
34 128 1 freebsd-boot (64k)
162 155189120 2 freebsd-ufs (74G)
155189282 1112173 - free - (543M)
=> 63 488397105 ada1 MBR (232G)
63 488397105 1 linux-data (232G)
$ du /dev/ada*
0 /dev/ada0
0 /dev/ada0p1
0 /dev/ada0p2
0 /dev/ada1
0 /dev/ada1s1
$ sudo mount /dev/ada1 /mnt/
mount: /dev/ada1: Invalid argument
$ sudo mount /dev/ada1s1 /mnt/
mount: /dev/ada1s1: Invalid argumentPlease help me mount /dev/ada1s1, thanks in advance :)

There is limited read only support for ext4 filesystems.
You can mount them by:
``# mount -t ext2fs -o ro /dev/name /mountpoint``
RE: <FreeBSD> cannot mount ext4 partition - venam - 03-07-2013
Since when BSD is able to mount ext4?
RE: <FreeBSD> cannot mount ext4 partition - yrmt - 03-07-2013
You can but in read only mode.

Code:
> sudo mount -t ext2fs -o ro /dev/ada1s1 /mnt
mount: /dev/ada1s1: Invalid argument
> sudo mount -t ext2fs -o ro /dev/ada1 /mnt
mount: /dev/ada1: Invalid argumentThanks for your answers, but it didn't work. :(

I thought it worked with ext2 in r/w and ext3 in r only.
theconjuring, you can still mount it with a rescue disk.

Yes I know I can mount them with a rescue disk, maybe I will need to back them up in a hard disk and reformat it to UFS so FreeBSD plays nicely.
Thanks for the help. :)

Oops, I confused ext4 for ext3, sorry.
RE: <FreeBSD> cannot mount ext4 partition - berk - 03-07-2013
"rescue disk", I don't have one. I downloaded ttylinux (65 MB) and tried to dd it to an USB, but it doesn't just work. :/
Code:
$ sudo dd if=ttylinux-pc_i686-16.1.iso of=/dev/da0
134764+0 records in
134764+0 records out
68999168 bytes transferred in 466.936130 secs (147770 bytes/sec)Doesn't boot. :/

Slitaz is also a solution and it comes with a GUI already installed (openbox).
RE: <FreeBSD> cannot mount ext4 partition - berk - 03-07-2013
Installed ext4fuse and ntfs-3g and I can read ext4 partitions. I can write on NTFS partitions, too.
Thank you, guys, problem solved.

Great, instead of putting <solved>, could you use [solved] for the future posts? Thanks
