genkernel udev-182 - e2fsck /usr cannot continue, aborting

castor_fou

after upgrading to udev-182, I understand that /usr is now mounted by initramfs. (I use genkernel)

However at boot time, Checking local filesystems ... is complaining it cannot check /usr, becuse already mounted (rw I guess ?)
Here is the message from rc.log :

I have the same problem. My /usr is on a separate partition, I am using genkernel and during evry boot I can see message "e2fsck cannot contine, aborting" because /usr is not mounted as ro. Any solution?

My initramfs checks /usr and /var before it mounts them if the mount count or whatever has been reached.
Its hand rolled, so when it breaks, the pieces are all mine.

JohnBlbec,

Heres the hard bit.
It has raid5, and LVM as well as mounting /var and /usr.
Adding LUKS or removing things you don't need is left as an exercise for the reader.
I use UUIDs everywhere, since the userspace mount command is in the initrd. blkid is your friend.
Every block device has a UUID. e.g. /dev/sda1 is a block device, so it has a UUID. The filesystem on /dev/sda1 is also a block device. It has its own but different UUID. Be sure to use the right UUIDs.

You feed initramfs_list to gen_init_cpio, which can be found in /usr/src/linux/usr and it outputs the corresponding initramfs, straight into /boot if you want.

From memory, gen_init_cpio supports -h or --help.

The Gentoo Wiki is another good source of information.

NeddySeagoon,

thank you for your post. i will study your solution (i know the article on wiki, of course). i would expect that genkernel itself generates the right initramfs and i would prefer that way but it seems it does not. unfortunately. ok, thanks once again.

JohnBlbec,

I'm old and cynical and don't trust black magic at all, since I have to fix it when it breaks anyway.
For me, that means I need to make my own initrd.

I understood you but I am lazy. Unfortunately, there is no other way then yours to be satisfied...

How about using dracut ?

It seem to create a initramfs that will perform a fsck before mounting / and /usr.
