Subject: [Discuss] btrfs tip
Message-ID: <2665135f-a7cb-93ba-a1fb-84f8c4bf10fd@mattgillen.net>

Came back from vacation to a dead disk in my main linux server.  Disk
had been dying for a while, and we had a power outage at some point
while I was gone which must have finished it off.  Kernel had been stuck
trying to initialize the disks on boot for 3 days.

Protip: if you use btrfs as your root filesystem, and use a
RAID1/mirroring configuration, then add the 'degraded' flag to your grub
kernel command line.  That will allow it to mount (and boot) even if a
disk dies.  Don't know why this isn't the default...

If you don't do that (or manually edit the command line to add it if you
have console access) you have to boot off a rescue USB that understands
btrfs in order to start the 'btrfs replace' operation.

To do this, you add to the rootflags parameter:
   rootflags=subvol=root,degraded

Where do you set that?  The grub config keeps moving around.  Currently
my Fedora33 box the actual command lines for the kernel are in:
/boot/loader/entries/*.conf

(note that it needs to be on the kernel command line, having it as an
option in /etc/fstab is not sufficient, at least when it comes to the
root filesystem)

Good point, but it isn't really different than if the disk dies while
the system is up. Not certain what happens when it dies online, but I
suspect you'd need some cron job (or logcheck) checking with a
notification mechanism.  The linux software RAID mechanism has it's own
e-mailing notification system that doesn't rely on watching syslog or
polling /proc/mdstat, I don't think btrfs has something like that yet.
(there are some nice cron-friendly scripts here
  https://github.com/kdave/btrfsmaintenance
but they don't seem to cover the case of monitoring mirrors)  I can kind
of understand why, RAID-1/mirroring is only one of many things you can
do with btrfs, whereas the software-RAID system has one thing that it does.

The problem is that unless you have hot-swap HD chassis in your server,
you /have/ to bring the system down to replace the disk, and you can't
do the 'btrfs replace' operation until you have the new disk online.  So
at some point you're going to need to mount with the 'degraded' option
in order to fix it.

A cron job to check status could look something like
  btrfs filesystem show | grep missing

---

Further investigation turned up this thread that explains why the
default is to not allow degraded mounts:
https://www.reddit.com/r/btrfs/comments/kguqsg/degraded_boot_with_systemd/

The key comment is by 'cmmurf' and the issue is about timing of device
discovery (the current age of multiple hot-plug interfaces makes this
harder than it used to be).  I'm not sure how to interpret his comment
though, it sounds as if 'degraded' at boot time always runs the risk of
doing the 'split brain' thing, which seems unfortunate; it would mean
that the only safe way to replace a drive on a btrfs root filesystem
involves booting from a rescue environment.

I would have to understand how udevadm works in
/usr/lib/udev/rules.d/64-btrfs.rules to say for sure if the 'split
brain' is a problem with the udev rules as they are, but I am now less
certain that 'degraded' is a good thing to put in your default grub
linux command lines.  'cmmurf' did explain why my system was happily
waiting for three days for the disk to become ready though... (those
very udev rules that prevent problems for btrfs)

Hi,
    I'm working on a project with the Revive adserver and having a few
issues. The server appears to leave all tracking off by default. I would
like to turn everything on for the analysis underway. Does anyone have any
experience with Revive? If so, have you enabled the full range of tracking

Message-ID: <98798782-a804-1cc3-3cfb-0937b9a13484@icloud.com>

On my HP Envy laptop running Ubuntu 20.04.2 LTS, the Files application 
doesn't show USB or sdcards.

I can see USB in terminal in /dev.  However I can't see the sdcard.

	eric at dragonEnvy:/media/eric$ ls -la /dev/sd*

	brw-rw---- 1 root disk 8, 16 Jul  9 13:19 /dev/sdb  // the USB dongle

Is the sdcard card reader recognized?  I _think_ yes.

	sudo lspci -v -nn

I tried a rescan but no help.

Shouldn't the drives be shown in /media?

	eric at dragonEnvy:/media/eric$ ls -lah /media
	total 12K
	drwxr-xr-x   3 root root 4.0K Apr 25  2020 .

I see a little plus sign.  Maybe I changed something here a while back 
and forgot.  Maybe this is an acl or permission issue?  So now I'm 
thinking maybe just leave the USB and sdcard in and reboot.  Maybe root 
will set them up on initialization.  Didn't work.

Interesting errors on reboot in auth.log but after investigation I think 
it is cruft from pam that can be ignored.

Let's check media directory permissions.

	# owner: root
	# group: root
	user::rwx
	user:eric:r-x
	group::---
	mask::r-x

Oddly I can plug in a mouse or my iPad and everything works fine.  I 
plug in an USB dongle or my little SandDisk card and nothing.  What do 
you think?  Where else to look?

Thanks for any tips!

What is the partition type on the card, ntfs? If it is ntfs 
then maybe you need to install a helper program to be able 
to mount and read the partition on the card.

I would try "sudo fdisk -l /dev/sdb"

If it does not show any suitable filesystems, then that's the problem 
and not any file permissions.

Hi,

I deleted the 'eric' directory in /media as I may have done something 
weird to it a while back.  I'm always screwing with things.  Then I did 
your suggestion.

eric at dragonEnvy:/dev$ sudo fdisk -l /dev/sdb

	Disk /dev/sdb: 57.86 GiB, 62109253632 bytes, 121307136 sectors
	Disk model: Ultra Fit
	Units: sectors of 1 * 512 = 512 bytes
	Sector size (logical/physical): 512 bytes / 512 bytes
	I/O size (minimum/optimal): 512 bytes / 512 bytes

I couldn't see sdb in the Disks GUI which runs as root earlier today but 
now I can.  In Disks the volume is seen but unknown.  I reformatted / 
partitioned the volume as EXT3.  I told it to overwrite everything with 
zeros and it looks like it's going to take about an hour.  However this 
is all a very good sign.

Now back to trying to figure out the sdcard.  I wager the issue is similar.

Thanks all!

For the life of me I can't get the laptop to show sdcards.  I give up. 
Maybe a driver issue.  It's been a couple of hours.

As a workaround I have a neat little Vivitar sdcard to USB A & C 
adapter. Using this I have no issues.

Thanks again for the suggestions!

If you're connecting an SD card directly to your computer, it'll show up
as /dev/mmcblkX rather than /dev/sdX, with partitions as /dev/mmcblkXpY.
If you can't find anything there, you should check dmesg(1) to see what
errors, if any, the mmcblk driver is reporting.

Hi,

Nothing in /var/log/dmesg on startup or when inserting / removing the 
sdcard.  Also nothing in /dev starting 'mm' when inserted.

I suspect the driver is not functional.  Currently having a cup of tea 
and searching around to see if one exists.

Great suggestion though.

Thanks,

Eric C

Actually I think the issue has something to do with which kernel modules 
are being used.  Might take me a while to figure it out as I rarely play 
with those.

Fun side note, I just did man lsmod and see Jon Masters is one of the 
authors.  We know him!  He gave a great talk at a BLU meeting.  Small world.

Thanks,

Eric C

After further digging there is a known regression with rts5229 on 
kernel.org.  I think that is the issue.  Oh well.  At least we got the 
USB working.  I can live without the sdcard.

Thanks again all!

Summary:

Retrospective look at a decade of Single Board Computing

Abstract:

Please join us for a walk down memory lane as we look at the history of 
Single Board Computers (SBCs), Systems-on-chip (SOCs), Systems-on-chip 
(SOMs), and dev boards as members talk about the ones that they used 
most. We will discuss the history of embedded Linux in advance of the 
ELC and HPEC conferences and talk about how the embedded hardware 
hacking community supported the larger Linux movement and vice versa.

Bio
Federico Lucifredi is The Ceph Storage Product Management Director at 
Red Hat, formerly the Ubuntu Server PM at Canonical, and the Linux 
?Systems Management Czar? at SUSE.

Jason Kridner is Open Platforms Technologist/Evangelist for Texas 
Instruments, where he focuses on defining strategy for growing TI's open 
platform ecosystem for developers and customers. Jason is the co-founder 
and community manager for BeagleBoard.org, designers of BeagleBone 
Black. Jason is named on 11 patents and has been programming personal 
computers since 1979 as a hobbyist and professional. He worked on the 
first wave of MP3 player designs in 1998. Jason will talk about his 
experiences developing BeagleBone into an open computing platform that 
is powered by a 1GHz ARMv7 CPU and 2 200MHz 32-bit microcontrollers with 
real-time capabilities.
