`Invalid argument' problems with mount_ext2fs

`Invalid argument' problems with mount_ext2fs

Post by Donn Mille » Wed, 11 Aug 1999 04:00:00



I'm having a bit of trouble with mount_ext2fs on FreeBSD 4.0-CURRENT.
When I mount my two Linux partitions, /dev/wd1s2, and  /dev/wd1s4, I don't
get any error messages from the `mount' command.  But yet, when I cd to
/mnt/usr/include, and do `ls', here's what I get:

ls: include: Invalid argument
ls: info: Invalid argument
ls: ix86-coff: Invalid argument
ls: ix86-linux: Invalid argument
ls: ix86-linuxaout: Invalid argument
ls: libexec: Invalid argument
ls: man: Invalid argument
ls: openwin: Invalid argument
ls: sbin: Invalid argument
ls: share: Invalid argument
ls: src: Invalid argument





I'm assuming this has something to do with the following boot-up error
message:

Aug 10 03:06:36 myname /kernel: wd1s4: raw partition size != slice size

Notice, wd1s4 is the `/usr' partition of my Linux installation.

I get no problems at all with wd1s2, which is the `/root' of my Linux
installation.  I don't get any error messages at all about this
partition's slice size on boot-up, and hence I get no errors with
mount_ext2fs with this slice.

Regarding the raw partition size != slice size problem, is there any
special flags I can pass to mount to make the problem go away?  I don't
know exactly is there's a problem with my partition table on drive two,
but I don't have any problems when running Linux.

1. `Invalid argument' problems with mount_ext2fs


I've never gotten that message when _mounting_ an ext2fs filesystem.  But
during boot-up, I get this:

wd1s4: raw partition size != slice size
wd1s4: start 846720, end 2128895, size 1282176
wd1s4c: start 846720, end 947519, size 100800



No error messages here during mount.

Now, I cd /mnt/usr, and do an ls:

-snip-

ls: ix86-linuxaout: Invalid argument
ls: libexec: Invalid argument
ls: man: Invalid argument
ls: openwin: Invalid argument
ls: sbin: Invalid argument
ls: share: Invalid argument
ls: src: Invalid argument





This seems related to the message I was getting on bootup:

wd1s4: raw partition size != slice size
wd1s4: start 846720, end 2128895, size 1282176
wd1s4c: start 846720, end 947519, size 100800

Maybe when I did fdisk in Linux on these partitions, it did something
off-the-wall that FreeBSD's mount_ext2fs didn't understand.  I don't think
it could be the inode density I've used when formatting my Linux /usr
partition (in this case /mnt/usr).

It probably also depends on the version of FreeBSD you are using.  What
doess uname -sr give you?

FreeBSD 4.0-CURRENT
^^^^^^^^^^^^^^^^
This is what I'm running right now.

I think that ext2fs hasn't been maintained as well as it used to.  Or, in
may case, maybe I did something slightly off the wall in Linux that may be
acceptable to the Linux kernel, but FreeBSD doesn't recognize what I've
done.
