Dracut should work fine with btrfs built into the kernel natively or as a module, though if you want to boot directly it will have to be native Yes, of course, I understand that. I tried it both ways round, as I said. I believe that as long as dracut can find the btrfs utility it will put it in the initramfs. I'll check that again with lsinitrd. Otherwise there isn't much more to this - I think these two issues are the only real problems you're having, depending on which route you decide to take with the initramfs (which I still recommend, but you could of course have separate grub lines to boot with and without it if you want to experiment).

Re: [gentoo-user] To Wifi or not to Wifi...
Hi Mick,
thanks a lot for linking this informations for me :)
My Lollipop device is a pure tablet. I choose
intentionally a no-gsm/no-phone device...of
smartphones I only like the smart part.
And yesterday evening I put Linux on it...currently
only as chroot environment (since nobody has currently
made public a custom rom/kernel) so the android kernel
is still running, but ... one step is done.
I am eager to see the first custom ROMs for my device
(Asus MeMO Pad 7 ME176CX) and a cwm/twpr for it made
by the guys at clockworkmod.com/Team Win...can't wait...
really :)
Until then I have to be careful with modding, since there is no simple
way of replay a nandroid backup.
Have a nice weekend!
Best regards,
Meino

Hi Joost,
your are right: It is Android Lollipop 5.0 ! :)
Same version as my mobile phone. (After the latest update)
I think specialists experienced in networks, Wlans, Wifis and
such know and are experienced in hacking into others devices. Changing
the MAC may or may not a tool for that ... I simply dont know. I am
just at the start to get Wifi working ... a very basic problem for
others like you I think. For me...it is just a challenge.
Are you experienced in breaking in someone elses WIFI via changing the
MAC? Where came your idea from?
I played around with it in the past, not recently though.
MAC-based access control lists are simple and lightweight. Which is why I
use
them for WIFI networks (apart from the guest-WIFI). But I don't consider
them
secure enough to only rely on those.
I only actively set MAC-addresses for VMs to avoid duplications. I don't
see
the point in setting them specifically as they tend to be unique in my
experience.
Only other reason I can think off for changing the MAC-address is to get
around
a MAC-based filtering.

Re: [gentoo-user] Can't boot btrfs
Peter Humphrey wrote:
Hello list,
I've created a new btrfs volume on SSDs, complete with a lot of subvolumes
corresponding to the old lvm2 logical volumes. I took the opportunity of
removing a couple of old partitions, so I now have this:
/dev/sd[ab]1 form /dev/md1 as /boot,
/dev/sd[ab]2 are my rescue system: sda2 is its root, sdb2 is its portage tree,
/dev/sd[ab]3 is the btrfs file system.
I can boot my rescue system with no problems, but not the main system - I get
a kernel panic with BTRFS: failed to read the system array on sda3. I'm
writing this after chroot, su - prh, startx.
Both in the main and rescue systems I have this:
$ grep -i btrfs /usr/src/linux/.config
CONFIG_BTRFS_FS=y
CONFIG_BTRFS_FS_POSIX_ACL=y
# CONFIG_BTRFS_FS_CHECK_INTEGRITY is not set
# CONFIG_BTRFS_FS_RUN_SANITY_TESTS is not set
# CONFIG_BTRFS_DEBUG is not set
# CONFIG_BTRFS_ASSERT is not set
The relevant grub.cfg entries (I've moved to grub-2) are:
menuentry 'Gentoo Linux 4.0.5, no network' {
linux /boot/kernel-x86_64-4.0.5-gentoo root=/dev/sda3 softlevel=nonet
net.ifnames=0 irqpoll
}
menuentry 'Rescue System 4.0.5' {
linux /boot/kernel-x86_64-4.0.5-gentoo-rescue root=/dev/sda2
net.ifnames=0 irqpoll
}
Something seemed to be wrong in the kernel setup, so to test that I compiled
the main kernel with the .config from the rescue system. Same result.
Another test: I wondered whether, somehow, the btrfs volume included the name
of the mount point where it had been created, and would only allow itself to
be mounted there. Not so: moving its mount point in the rescue system didn't
prevent it from being mounted. I didn't expect it would, since the kernel
panic occurs long before fstab is read.
The other thing I've tried is to build an initramfs with dracut. I tried to
include its btrfs module but it refused because it couldn't find a command
btrfs. So I recompiled the kernel with btrfs as a module and added
'filesystems+=btrfs ' into dracut.conf. Still no success.
After a few days of floundering around, copious googling and getting splinters
under my fingernails I'm out of ideas. Can anyone see what else I can try? I
created the btrfs with mkfs.btrfs -m raid1 -d raid1 --label GENTOO /dev/sda3
/dev/sdb3. I've done that twice, with all the subvolume creation and backup
recovery, the second time with --force.
This may not be related but thought I would mention. For some reason,
my system will not boot a kernel newer than 3.18.7. I use
gentoo-sources and generally use make oldconfig. I have also tried the
new 4.0 kernels as well. They try to boot but don't make it past the
kernel trying to do its thing. I don't reboot often so I have not had
the chance to figure out exactly why this is happening. Recently I had
to start using that pesky init thingy but I don't think that is causing
the problem. I get a error/panic and then it says it is going to
reboot in 10 seconds. By the time I figure out where the failure might
be, it reboots itself.
I thought I would mention just in the rare event you are running into
the same issue I am. Just a thought. If you know this isn't the
problem, just ignore and carry on.

[gentoo-user] Gentoo on Android and the problem of space
Hi, on my tablet PC I used an Android App called Linux deploy to install an chroot-environment for - guess - Gentoo. :) The tablet has a SDcard slot and recognizes any FAT32 formatted SDcard automatically. Anything else will silently be ignored. Furthermore Linux deploy uses a single file when it is pointed to an external SDcard (with FAT32) which is mounted via a loop device, formatted ext4, and then populated with the Gentoo Linux files. So far so nice. Unfortunately the file size is limited to 4GB, which is not /that/ much in respect to what I want to install later (Linux deploy goes as far as LXDE runs a terminal and only a few moe things). I created a second file of 4GB and set it up as a second partition. This is now additional storage capacity of another 4GB. BUT: Linux deploy already installed a full rootfs and more on the first file. And I need to increase the size of _the whole rootfs_ with this extra file ... not only the storage capacity located behind a certain mountpoint.

Rich Freeman rich0 at gentoo.org writes:
As many know, I have made many failed attempts to get btrfs in raid 1
working on gentoo, and have to this date, failed.
Interesting. I've never had any problems with it. I boot using
grub2+dracut with root on a single-device btrfs, and /usr on a
multi-device raid1 btrfs (and dracut mounts both).
WE should focus on Peter's needs, as this is his thread.
As long as you pass a valid root= dracut should just find and mount
all the devices for your root. Note that it will attempt to read
/etc/fstab and remount your root using whatever is in that, so make
sure it is valid.
Some relevant config:
from grub.cfg:
linux /root1/boot/vmlinuz-3.18.19
root=UUID=7d9f3772-a39c-408b-9be0-5fa26eec8342 ro
rootflags=subvol=root1 init=/usr/lib/systemd/systemd
video=1920x1080-32 at 60 crashkernel=64M net.ifnames=0
libahci.ignore_sss=1
initrd /root1/boot/initramfs-3.18.19.img
from fstab:
/dev/disk/by-uuid/7d9f3772-a39c-408b-9be0-5fa26eec8342 /
btrfs noatime,ssd,nodiscard,compress=none 0 0
/dev/disk/by-uuid/cd074207-9bc3-402d-bee8-6a8c77d56959 /data
btrfs noatime,compress=none 0 0
Compression is transparent - the mount option only affects future
writes to the device, and you don't need anything to correctly mount
the drive.
I have dozens and dozens of excellent links on btrfs. I've read hundreds and
hundreds of postings and docs, some even about other folks successes with
btrfs and raid-1. I can install btrfs and put gentoo on it. Successfully
configuring the system files, rebooting and enjoying raid-1 on btrfs evades
me. I file a bug (bgo 548930) requesting support for btrfs in the
gentoo handbook. It's not even assigned to anyone...
So, a smart (and really cool dude like yourself) surely can take the
handbook, and edit out an experimental version that only address btrfs-raid
one? That way a following of folks could 'monkey see monkey do' install
gentoo on raid -1? (You'd be a very popular person with lots of
commoners. (struggling admin types?).
The way I see it there are (2) main cases and (2) minor cases::
(1) main case:: efi system with drives 2T
(1_a) minor case efi system with drives 2T
(2) main case :: mbr/bios system with Drives 2T
(2_b) minor case:: mbr/bios system with drive 2T
Either of these cases in a format of the gentoo handbook, could
simple removed all references to all files systems but btrfs.
Hell, I'd be willing to send some dollars to whomever or (whatever charity)
for that..
Once that happens, then surely we could get an unofficial install script
Note:: the OpenSuse-13.2 install does not even need a ext boot partition as
it uses btrfs for every partition. I think that sort of doc, is really what
Peter, myself and many others need:: and is consistent with 'the gentoo way'?
In my mind all new/default gentoo installs should be raid-1 as that would
eliminate many postings for help on gentoo_user {imho} YMMV.

Hi Joost,

Are you experienced in breaking in someone elses WIFI via changing the
MAC? Where came your idea from?
I played around with it in the past, not recently though.
MAC-based access control lists are simple and lightweight. Which is why I
use
them for WIFI networks (apart from the guest-WIFI). But I don't consider
them
secure enough to only rely on those.
I only actively set MAC-addresses for VMs to avoid duplications. I don't
see
the point in setting them specifically as they tend to be unique in my
experience.
Only other reason I can think off for changing the MAC-address is to get
around
a MAC-based filtering.

[gentoo-user] Can't boot btrfs
Hello list,
I've created a new btrfs volume on SSDs, complete with a lot of subvolumes
corresponding to the old lvm2 logical volumes. I took the opportunity of
removing a couple of old partitions, so I now have this:
/dev/sd[ab]1 form /dev/md1 as /boot,
/dev/sd[ab]2 are my rescue system: sda2 is its root, sdb2 is its portage tree,
/dev/sd[ab]3 is the btrfs file system.
I can boot my rescue system with no problems, but not the main system - I get
a kernel panic with BTRFS: failed to read the system array on sda3. I'm
writing this after chroot, su - prh, startx.
Both in the main and rescue systems I have this:
$ grep -i btrfs /usr/src/linux/.config
CONFIG_BTRFS_FS=y
CONFIG_BTRFS_FS_POSIX_ACL=y
# CONFIG_BTRFS_FS_CHECK_INTEGRITY is not set
# CONFIG_BTRFS_FS_RUN_SANITY_TESTS is not set
# CONFIG_BTRFS_DEBUG is not set
# CONFIG_BTRFS_ASSERT is not set
The relevant grub.cfg entries (I've moved to grub-2) are:
menuentry 'Gentoo Linux 4.0.5, no network' {
linux /boot/kernel-x86_64-4.0.5-gentoo root=/dev/sda3 softlevel=nonet
net.ifnames=0 irqpoll
}
menuentry 'Rescue System 4.0.5' {
linux /boot/kernel-x86_64-4.0.5-gentoo-rescue root=/dev/sda2
net.ifnames=0 irqpoll
}
Something seemed to be wrong in the kernel setup, so to test that I compiled
the main kernel with the .config from the rescue system. Same result.
Another test: I wondered whether, somehow, the btrfs volume included the name
of the mount point where it had been created, and would only allow itself to
be mounted there. Not so: moving its mount point in the rescue system didn't
prevent it from being mounted. I didn't expect it would, since the kernel
panic occurs long before fstab is read.
The other thing I've tried is to build an initramfs with dracut. I tried to
include its btrfs module but it refused because it couldn't find a command
btrfs. So I recompiled the kernel with btrfs as a module and added
'filesystems+=btrfs ' into dracut.conf. Still no success.
After a few days of floundering around, copious googling and getting splinters
under my fingernails I'm out of ideas. Can anyone see what else I can try? I
created the btrfs with mkfs.btrfs -m raid1 -d raid1 --label GENTOO /dev/sda3
/dev/sdb3. I've done that twice, with all the subvolume creation and backup
recovery, the second time with --force.

Btrfs needs to scan the build the array, which is normally done from an
initramfs. As you are not using one, you need to specify both devices
using the device= syntax posted in the Hubris thread.

As Neil already pointed out, if you're not using an initramfs you need
to put all your devices on this line if they're part of an array. The
kernel will not scan to find the others.
If you do use an initramfs you really should use a UUID or label
instead of a device name, but a device name will work as long as it
happens to not get reordered on you.
The other thing I've tried is to build an initramfs with dracut. I tried to
include its btrfs module but it refused because it couldn't find a command
btrfs. So I recompiled the kernel with btrfs as a module and added
'filesystems+=btrfs ' into dracut.conf. Still no success.
Do you have btrfs-utils installed? Dracut should work fine with btrfs
built into the kernel natively or as a module, though if you want to
boot directly it will have to be native (which is one of the reasons
most distros always use an initramfs - they want a modular kernel but
can't predict what your root is running on).
I believe that as long as dracut can find the btrfs utility it will
put it in the initramfs.
Otherwise there isn't much more to this - I think these two issues are
the only real problems you're having, depending on which route you
decide to take with the initramfs (which I still recommend, but you
could of course have separate grub lines to boot with and without it
if you want to experiment).
