 |
|
I selected "Use ext4 for ext2/ext3 file systems" and am not able to mount an ext2 partition.
i get | Code: | mount /boot
mount: unknown filesystem type 'ext2' |
It mounted the ext3 partition fine.
Relevant fstab:
| Code: | /dev/sda3 /boot ext2 noauto,noatime 1 2
/dev/sda6 / ext3 noatime 0 1

Look at the contents of /proc/filesystems
Make sure ext2 is listed in there. It's the list of filesystem types your kernel supports. Did you also select the ext2 filesystem option separately? Like maybe as a module? |

Thanks for the replies.
Here is the relavent stuff from those files:
| Code: |
/dev/sda3: UUID="2b87da1b-e0ac-485c-80e9-ba28e85735d1" TYPE="ext2"
|
| Code: | /dev/sda3 /boot ext2 noauto,noatime 1 2
|
This issue came up on a system I am updating for a friend.
had a working fstab.
My first idea was to compile the ext2 as a module and tried to load it no luck.
Had to recompile kernel and deselect under filesystems:
| Code: | | Use ext4 for ext2/ext3 file systems (NEW) |
and enable ext2 and ext3 support.
#Then walk some one through burning a livecd, booting a live cd, and coping copy kernel over to /boot (over the phone) since I am not where the computer is.
I had ext2 and 3 deselected assuming
| Code: | | Use ext4 for ext2/ext3 file systems (NEW) |
ment
| kernel-help-text wrote: | Allow the ext4 file system driver code to be used for ext2 or │
│ ext3 file system mounts. This allows users to reduce their │
│ compiled kernel size by using one file system driver for │
│ ext2, ext3, and ext4 file systems. |
Note to self and others This is not the case beware of this kernel option.

It seems like it's on your end, because for me it works as advertised:
| Code: | │ │ < > Second extended fs support │ │
│ │ < > Ext3 journalling file system support │ │
│ │ <*> The Extended 4 (ext4) filesystem │ │
│ │ [*] Use ext4 for ext2/ext3 file systems │ │
│ │ [*] Ext4 extended attributes │ │
│ │ [*] Ext4 POSIX Access Control Lists │ │
│ │ [ ] Ext4 Security Labels │ │
│ │ [ ] EXT4 debugging support │ │ |
| Code: | # mount | grep ext
/dev/root on / type ext4 (rw,noatime,user_xattr,acl,barrier=1,data=ordered)
/dev/sda1 on /boot type ext2 (rw,noatime,user_xattr,acl,barrier=1) |

I have been using this for over a year with no problem.
