A bash script to btrfs snapshot details like disk sizes (requires btrfs quota to be enabled)
Posted by jpluimers on 2016/09/06
One thing I’ve not figured out yet is this: How does enabling btrfs quotas impact the system? – Unix & Linux Stack Exchange
My gut feeling says it’s not much. But if someone knows: please chime in.
Anyway: btrfs quota support helps you to see how big snapshots (and other subvolumes) are.
Enabling and disabling is easy (the slash is the path from where to enable quota):
btrfs quota enable /
btrfs quota disable /
The bad thing is that there is no command that gives just the quota status. You have to revert to btrfs qgroup show /
This will show you quota groups when quota are enabled:
qgroupid rfer excl -------- ---- ---- 0/5 16.00KiB 16.00KiB
or errors when quota are disabled either of these two errors:
# btrfs qgroup show / ERROR: can't perform the search - No such file or directory ERROR: can't list qgroups: No such file or directory # btrfs qgroup show / ERROR: can't list qgroups: quotas not enabled
You might also want to check the syslogs as there was a [PATCH 1/2] btrfs: syslog when quota is enabled.
The btrfs qgroup output is the base for agronick/btrfs-size: A script that will print out a list of BTRFS subvolumes along with their size in megabytes and their name.
It actually shows it in human readable form (kilo/mega/giga/… bytes) and is documented at Get the size of your BTRFS Snapshots | PoisonPacket. It gives me a nice overview that corresponds to the snapper list output (see below).
The script has two drawbacks:
- when quota is disabled, you get this error:
./btrfs-size/btrfs-size.sh: line 55: can't + 0: syntax error: invalid arithmetic operator (error token is "'t + 0")
- it can take a while for
btrfs quota enable /to actually deliver the quota for all the qgroupid values snapper uses. Until that time, the columns ID/Total/Exclusive Data are empty. - it won’t warn you if the quota data is out of data; to check that, run the below script
# btrfs qgroup show / > /dev/null
WARNING: Qgroup data inconsistent, rescan recommended
In that case, run btrfs quota rescan / and wait for it to complete by running this command until the warning is gone:
# btrfs qgroup show / > /dev/null
WARNING: Rescan is running, qgroup data may be incorrect
If the warning reverts to WARNING: Qgroup data inconsistent, rescan recommended then you might see the effects from this bug and should not worry about it: Bug 933428 – btrfs qgroup – allways shows WARNING: Qgroup data inconsistent.
For more btrfs quota background information, see: UseCases – btrfs Wiki.

OpenSuSE Tumbleweed `zypper dist-upgrade`: `mt-st` versus `mt_st`
Posted by jpluimers on 2016/08/08
TL;DR: I’m not the only one being partially word-blind.
I had the below while performing a zypper distribution upgrade on "openSUSE Tumbleweed (20160726) (x86_64)".
revue:/etc # zypper dist-upgrade
...
Detected 2 file conflicts:
File /usr/bin/mt
from install of
mt-st-1.3-1.1.x86_64 (Main Repository (OSS))
conflicts with file from package
mt_st-1.3-1.2.x86_64 (@System)
File /usr/sbin/stinit
from install of
mt-st-1.3-1.1.x86_64 (Main Repository (OSS))
conflicts with file from package
mt_st-1.3-1.2.x86_64 (@System)
File conflicts happen when two packages attempt to install files with the same name but different contents. If you continue, conflicting files will be replaced losing the previous content.
Continue? [yes/no] (no): no
Problem occured during or after installation or removal of packages:
Installation aborted by user
Please see the above error message for a hint.
Did you see the cause of the error in the above message?
Neither did I.
So I went to the #opensuse-factory IRC channel on freenode with this information:
revue:/etc # zypper repos --details # | Alias | Name | Enabled | GPG Check | Refresh | Priority | Type | URI | Service --+-------------------------------------+----------------------------+---------+-----------+---------+----------+--------+----------------------------------------------------------------------------------------+-------- 1 | download.opensuse.org-non-oss | Main Repository (NON-OSS) | Yes | (r ) Yes | Yes | 99 | yast2 | http://download.opensuse.org/tumbleweed/repo/non-oss/ | 2 | download.opensuse.org-oss | Main Repository (OSS) | Yes | (r ) Yes | Yes | 99 | yast2 | http://download.opensuse.org/tumbleweed/repo/oss/ | 3 | download.opensuse.org-tumbleweed | Main Update Repository | Yes | (r ) Yes | Yes | 99 | rpm-md | http://download.opensuse.org/update/tumbleweed/ | 4 | http-download.opensuse.org-f3ba78e8 | server:monitoring | Yes | (r ) Yes | Yes | 99 | rpm-md | http://download.opensuse.org/repositories/server:/monitoring/openSUSE_Tumbleweed/ | 5 | openSUSE-20150508-0 | openSUSE-20150508-0 | No | ---- | No | 99 | yast2 | cd:///?devices=/dev/disk/by-id/ata-VMware_Virtual_IDE_CDROM_Drive_10000000000000000001 | 6 | repo-debug | openSUSE-Tumbleweed-Debug | No | ---- | Yes | 99 | NONE | http://download.opensuse.org/debug/tumbleweed/repo/oss/ | 7 | repo-source | openSUSE-Tumbleweed-Source | No | ---- | Yes | 99 | NONE | http://download.opensuse.org/source/tumbleweed/repo/oss/ | revue:/etc # cat /etc/os-release NAME=openSUSE VERSION="Tumbleweed" VERSION_ID="20160726" PRETTY_NAME="openSUSE Tumbleweed (20160726) (x86_64)" ID=opensuse ANSI_COLOR="0;32" CPE_NAME="cpe:/o:opensuse:opensuse:20160726" BUG_REPORT_URL="https://bugs.opensuse.org" HOME_URL="https://www.opensuse.org/" ID_LIKE="suse"
There cooloo pointed out both the cause and solution were deceptively simple:
coolo: wiert: zypper remove mt_st ; zypper dup; zypper in mt-st
coolo: the package was incorrectly renamed
My partial word-blindness didn’t spot the difference between mt_st and mt-st, but it was indeed renamed.
So here I went:
zypper remove mt_st ; zypper dist-upgrade; zypper install mt-st
Note that strictly zypper install mt-st isn’t needed on my system as it is part of Base:System. which means that zypper dist-upgrade automatically re-installed it.

bash – How can I convert tabs to spaces in every file of a directory? – Stack Overflow
Posted by jpluimers on 2016/08/05
Kev:
Try the command line tool expand.
expand -t 4 input >output
And for those systems that don’t use the GNU Core Utilities, you have a decent chance of expand being installed since it is standardized by The Open Group’s Single Unix Specification. See Issue 6, which is from 2001, though some updates were applied, hence the year of publication being 2004: expand

moreutils: sponge
Posted by jpluimers on 2016/07/29
sponge, a great *nix tool part of moreutils:
sponge: soak up standard input and write to a file
Now need to figure out how to get it on Tumbleweed; maybe http://rpm.pbone.net/index.php3/stat/4/idpl/23781842/dir/opensuse/com/moreutils-0.48-1.1.i586.rpm.html

HOWTO: Multirouting with Linux : Luke Cyca Dot Calm
Posted by jpluimers on 2016/07/08
Multihoming without BGP with home routers and Linux. Need to apply this on OpenSuSE one day: HOWTO: Multirouting with Linux : Luke Cyca Dot Calm.
Basically it does Multirouting of Sessions using NAT, routing tables, rules, removal of the default routing and adding a round robin routing, fixing DNS, adding more rules and creating a failover script.
In case it ever goes offline: the WayBack Machine link.
Some more background research links:
- Name Resolution on multi-homed networks using dnsmasq?.
- Need help with Dual NICs.
- networking – Hooking Linux machine to secondary router/ISP: how to setup routing correctly? – Super User.
- Shorewall and Multiple Internet Connections.

Aliases for tools removed from `net-tools` package – via: openSUSE Build Service
Posted by jpluimers on 2016/06/16
Since quite a few commands that you regularly see mentioned on the web have been removed from OpenSuSE net-tools, I’ve created a few bash aliases in /etc/bash.bashrc.local below.
Note the original commands are not good have been deprecated for years on various distros and therefore removed:
# stuff removed from net-tools # see https://features.opensuse.org/317197 and https://build.opensuse.org/package/view_file/network:utilities/net-tools/net-tools.changes ## Because of changes on Thu Apr 10 12:33:41 UTC 2014 alias "arp=echo 'use \"ip neigh\" or \"ip -r neight\"' && ip neigh" alias "ifconfig=echo 'use \"ip a\"' && ip a" alias "netstat= echo 'use \"ss\" or \"ss -r\"' && ss" alias "route=echo 'use \"ip r\"' && ip r" ## Because of changes on Sun Mar 29 00:41:21 UTC 2015 alias "ipmaddr=echo 'use \"ip maddr\"' && ip maddr" alias "iptunnel=echo 'use \"ip tunnel\"' && ip tunnel"
Some bits of the net-tools change-log:
------------------------------------------------------------------- Sun Mar 29 00:41:21 UTC 2015 - jengelh@inai.de - ipmaddr and iptunnel are obsolete too, move them to subpackage. (Superseded by `ip maddr` and `ip tunnel`) - remove redundant %clean section ------------------------------------------------------------------- Thu Apr 10 12:33:41 UTC 2014 - mmarek@suse.cz - Move arp, ifconfig, netstat and route to a -deprecated subpackage (fate#317196, fate#317197) - Drop the rarp tool, which has been broken since kernel 2.3
Note that the -lntu parameter seems to be the same for both ss and netstat: [WayBack] Get a list of Open Ports in Linux – Super User

OpenSuSE Tumbleweed notes
Posted by jpluimers on 2016/06/13
After zypper dup (dist-upgrade) or zypper up (update) a zypper ps will list processes using deleted files (i.e. processes that likely need to be restarted).
Some processes that can be restarted without reboot:
- vmtoolsd or vmware-vmblock-fuse
- irqbalance
- rcirqbalance restart
- login
- logoff
- polkitd or dbus-daemon
- nscd
- sshd
- rcsshd restart
- logoff/logon if you are holding one of the ssh sessions
- named
- rcnamed restart
- cron
- rccron restart
- ntpd
- rcntp restart
- smbd
- rcsmd restart
- nmbd
- rcnmb restart
- cupsd
- rccups restart
- dmeventd
- dmeventd -R
- snapperd
- rcdbus restart
- shellinaboxd
- rcshellinabox restart
- monit
- rcmonit restart
-
auditd
- rcauditd restart
-
haveged
- rchaveged restart
- systemd
To research
- dhcpcd
- rs:main
- agetty
- lvmetad
- agetty
- dmeventd
Some processes that require a reboot:
- systemd-journald
- systemd-udevd
- systemd-logind
- login
- (sd-pam
- although maybe not, but better safe than sorry
- gpg-agent
- wickedd, wickedd-auto4,wickedd-dhcp6,wickedd-dhcp4 and wickedd-nanny

TUMBLEWEED: local console yast linedrawing characters garbage after first reboot
Posted by jpluimers on 2016/06/09
I long while after asking TUMBLEWEED: local console yast linedrawing characters garbage after first reboot, I researched the issue further.
First the workaround:
It is enough if any user on any console (for which /usr/bin/tty will usually show /dev/tty#) runs /bin/unicode_start.
After that, any user that logs on on any console will get the correct line-drawing characters with yast.
Then about the problem:
It looks like the problem is that during boot, nothing calls /bin/unicode_start. This was a solved bug, but seems to be back in Tumbleweed so I posted a comment to the bug.
I don’t think it is related to a truckload of PuTTY UTF-8 line-drawing issues like below. I’ve included them just for reference in any case proves me wrong (:
- Getting Midnight Commander line drawing to work with PuTTY | andremiller.net.
- linux – Making 256-color AND Line drawing characters both work in PuTTY – Super User.
- Putty with utf8 on a SuSE System | BStar’s Code Snippets.
- Support | NCurses and Yast line distortion with putty.
- linux – Why does YaST now show lines as lqqqqqqqqqqqqqqq? – Super User.
Same for changing unicode_start by hand:
- YaST wirre zeichen? – SuSE – VDR Portal.
- [yast-commit] [yast/yast-installation] 25cd09: – call unicode_start/stop.
- [SLE] garbage character for YaST text via ssh on SuSE 9.0.
–jeroen
via:
- [Bug 556555] in textmode after changing console language Yast2 graphics.
- YaST: Display problems after upgrade.
- weiß jemand wie / wo unicode_start automatisch gestartet wird. bei der 13.1 hat man das anscheinend vergessen? (not yet archived at the WayBack machine) .
