[gentoo-user] gentoo-sources-2.6.29-r5 & ext4

[gentoo-user] gentoo-sources-2.6.29-r5 & ext4

[Daniel Iliev]

Hi,

Yesterday I decided to try gentoo-sources again. I was using vanilla,
because of ext4 - when it was declared stable, gentoo-sources still was
at the ext4dev phase (a version or so behind the upstream as expected).
Yesterday, when migrating from vanilla-2.6.28 to gentoo-sources-2.6.29-5
I haven't noticed any new FS related options except for the btrfs which
I don't need, thus have disabled.

Kernel compiles w/o errors, but when booted it panics with error msg
like "unknown mount option ``extents''".

Yes, I have "extents" among the following options in fstab and
they work with vannila-2.6.28

"/dev/md1  /  ext4 stripe=2048,commit=2,extents,orlov,delalloc,\
errors=remount-ro,nodiratime,noatime 0 1"

Ideas, suggestions?

maybe ext4 depends on 'Broken' - as it should - and so it was not shown in 
menuconfig. As it was not shown, you did not enable it. Without enabling it, 
it wasn't compiled in ....

Sorry, perhaps I wasn't clear enough. It works if I disable the
"extents" mount option. The problem is that when something is declared
"stable" it should  be changed only for bug fixes, not generally and it
should be backwards compatible with minor versions at least. Especially
when talking about highly important things such as FS. Tonight I'm going
to test the latest vanilla and if it works, then I believe it's Gentoo's
fault which deserves a report in b.g.o.

It would be nice if someone could confirm this issue.

I think what Volker is _trying_ to get at is that maybe ext4 isn't  
compiled into your kernel, because maybe the options have changed in  
the kernel's .config files between vanilla-2.6.28 and gentoo- 
sources-2.6.29-5.

The error message you see might well be consistent with attempting to  
mount the volume using the ext3 driver.

Suggest you post the .config file against which you built your new  
kernel.

Stroller.

Have you also got ext3 built in, and have you specified the rootfstype
kernel boot parameter (in lilo or grub)?

Type adding "rootfstype=ext4" to your kernel boot parameters.

Yes to both questions:

.CONFIG:
grep -i ext3 .config
CONFIG_EXT3_FS=y
CONFIG_EXT3_FS_XATTR=y
CONFIG_EXT3_FS_POSIX_ACL=y
CONFIG_EXT3_FS_SECURITY=y


GRUB:
kernel /boot/vmlinuz real_root=/dev/md1 rootfstype=ext4

The extents mount option has been removed from 2.6.29:

Thanks. I'm back to gentoo-sources w/o this mount option. I believe the
ext4 team deserves a few bad words for this (and many good words for
the whole work), but I'll spare the rant. :)
