Hello,
I'm a Linux user, quite new to FreeBSD.
I recently installed FreeBSD 8.2-RELEASE amd64 as a backup server. These backups consist of the synchronisation between SAN snapshots of the FS I want to backup and ZFS filesytems.
In order to mount my Linux FS, I installed the port of e2fsprog, and it works great for EXT2/3, but not for EXT4:
I can fsck it :
But I can't mount it:
In dmesg:
I tried to deactivate some ext4 features of this fs on a Debian box, but I can't disable all of them:
And after that, the error is the same when I try to mount it on FreeBSD.
So my question is, is it a way to mount an EXT4 filesystem on FreeBSD? Even in ro, without journal.
Thank you,
jC

I can fsck it :
Code:
endor# fsck_ext2fs /dev/da1s2
e2fsck 1.41.14 (22-Dec-2010)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/da1s2: 63569/657072 files (0.2% non-contiguous), 498732/2624256 blocks
But I can't mount it:
Code:
endor# mount -t ext2fs /dev/da1s2 /mnt
mount: /dev/da1s2 : Invalid argument
In dmesg:
Code:
WARNING: mount of da1s2 denied due to unsupported optional features
I tried to deactivate some ext4 features of this fs on a Debian box, but I can't disable all of them:
Code:
root@xen0adm1:~# tune2fs -O ^flex_bg /dev/iscsi/xen0adm1-2011-09-30-14p2
tune2fs 1.41.12 (17-May-2010)
Clearing the flex_bg flag would cause the the filesystem to be
inconsistent.
root@xen0adm1:~# tune2fs -O ^uninit_bg /dev/iscsi/xen0adm1-2011-09-30-14p2
tune2fs 1.41.12 (17-May-2010)
root@xen0adm1:~# tune2fs -O ^dir_index /dev/iscsi/xen0adm1-2011-09-30-14p2
tune2fs 1.41.12 (17-May-2010)
root@xen0adm1:~# tune2fs -O ^extents /dev/iscsi/xen0adm1-2011-09-30-14p2
tune2fs 1.41.12 (17-May-2010)
Clearing filesystem feature 'extent' not supported.
So my question is, is it a way to mount an EXT4 filesystem on FreeBSD? Even in ro, without journal.
Thank you,
