MyBook Live Duo 21.02.2 / rootfs size

Installing and Using OpenWrt
1

Hi,

I've just installed the version 21.of OpenWrt on MyBook Live Duo.

The new rootfs size (102.4 MB) seems to be too little, I have only 3.4 MB free after installing all the necessary packages.

Filesystem                Size      Used Available Use% Mounted on
/dev/root               102.4M     96.9M      3.4M  97% /

The samba4 package (which is crucial for a NAS) itself occupies almost 25 MB, the whole /usr/lib is 65.5 MB.

As it was an upgrade from 19.07.3, I can still grow the filesystem to the former 256 MB, so it's not a big deal for me. But I think it would problem for anybody installing this version for the first time.

If anybody is interested, I can upload the results of "ls -laSr /usr/lib"
Maybe somebody could advise what can be removed...

Here it is.

you could probably replace samba4 with ksmbd

3

Thank you for the advice!

However, according to the statistics here its network performance is not yet up to the full samba implementation. :frowning:

Another statistics here shows a completely different picture. I wonder which one is true...

4

tbh, I haven't been able to get full speed using samba4 at all ...

they've done something between v3 and 4, and the performance is a lot worse, I think it's related to the parallelism/multi threading in your 2nd link.
With that said, your CPU will probably become a bottle neck anyway.

not using openwrt on the samba4 host though.

5

It seems that we have several options to provide smb/samba, but I think the real problem is that the root partition has been reduced to ~100MB, while this machine has several GB's/TB's of storage.

So my question is (as the title suggest): is there any reason for the root partition being this small?

6

it's usually 100MB, it applies (AFAIK) for all platforms with "flexible" storage, x86, RPi, whatever that runs from a memcard, etc ...

you can always resize it, though.

7

Yes, sure... I can resize it, but the next sysupgrade will overwrite the partition table again. :frowning:
And for a NAS with some raid drives it's not that funny to rebuild them so often. Not to mention the possibility of errors...

8

you can always pull out the drive, put the newest FS in (not the whole image), before putting it back in, not pretty, but should work, and should be safe for your data.

9

That's a good idea, but I don't have any device I can connect the HDD to. :frowning:
I've sold my last desktop machine, and my laptop has no SATA connector, only NVMe. I have a USB-SATA converter, but that cannot provide enough power to a 3.5 inch drive.
I had to be tricky to resize the partition also: change the two drives, boot from the other one, resize the not active partition, and then change them back.

So, I have to do the upgrade (and anything else) in-place... :frowning:

10

You could also roll your own image. Not only can you then include samba and other packages (and save yourself having to reinstall them after an upgrade) and some default config files, you can also increase the rootfs size as you see fit.

This can actually be done without a full-blown build system and compiling the whole image from scratch, it is also possible just with the "simplified" image builder. Once you downloaded and ungzipped the image builder, edit the .CONFIG file and change CONFIG_TARGET_ROOTFS_PARTSIZE, which by default is now set to 104, to whatever size in MiB you prefer for the rootfs.

11

I was afraid this would be the next answer... :confused:
I'm not yet prepared to jump into the build process, but it seems to be necessary.

Anyway, my next move will be to check if ksmbd is a feasible alternative to samba.
Do you have any advice how to remove all the samba related libraries, dependencies and settings and all (except by reflashing the whole image again...)?

12

this actually isn't bad, you could run two different openwrt versions or configurations, and switch the boot device, when going between them.

instead of writing the combined image, write the rootfs + copy kernel, to keep the old partition layout.

13

Actually, it's not that simple. I have two raid devices, one mirror (md0 / raid1) and another stripe set (md1 / raid0). This latter always complains when I swap the disks, so before I do that, I have to disable raid completely (/etc/config/fstab, /etc/config/mdadm). And it should be done parallel on both root partitions.

So, it should be planned and executed very carefully. I plan to create an small, basic openwrt disk to be used in case of partition and filesystem manipulation on the real "production" disks. It would be nice if the system could be able to boot from USB, but AFAIK it's not possible:
MBLD boot from USB

instead of writing the combined image, write the rootfs + copy kernel, to keep the old partition layout.

I've tried that a few times, it breaks dependencies of the installed apps, so I have start installing everything over again. :frowning:

and it should.

you shouldn't copy it over on fs level, but dd the whole rootfs image, and resize it afterwards, to fill the partition it was written to.

Oh, I see... Sorry, I misunderstood...
Seeing all these obstacles it seems to be easier to stop upgrading the system regularly (like I did between 19.07.3 and 21.02.2), unless there is some serious security issue. Or, doing the upgrades on another disk, and copy the partitions over. I'm kind of reluctant losing all my data by openwrt upgrades.

I assume you're not using it as a router, internet exposed devices are more vulnerable.

That's why I was specifically mentioning that it can be done with the "simpler" Image Builder. While I can do it, I am also not a big fan of compiling my own images from scratch. If it can be done with the Image Builder alone, I usually choose to go down that much simpler route. It is easier to setup, gives much more immediate results, and one can still use pre-compiled kernel modules from the official repository.

Indeed, like @frollic says it's also not a priority on devices that are not facing the big bad internet on one cheek.

What I personally do: To both keep track on my customisations and for convenience, I have a small shell script that I keep one level above the Image Builder directory that keeps my build parameters. Nota bene, this was written for 19.07 and as such still references samba36 (I haven't actually switched to 21.02 with my MBLs yet) and contains packages that I see fit on my MBL, so take this as a template not as a guide:

#!/bin/sh

# Package inclusions/exclusions
PACKAGES=""

# LuCI-SSL
PACKAGES="$PACKAGES luci-ssl"
# Remove PPP
PACKAGES="$PACKAGES -ppp -ppp-mod-pppoe -luci-proto-ppp"
# Remove IPv6
PACKAGES="$PACKAGES -ip6tables -odhcp6c -kmod-ipv6 -kmod-ip6tables -luci-proto-ipv6"
# Remove dnsmasq and odhcpd (will never be a DNS server)
PACKAGES="$PACKAGES -dnsmasq -odhcpd -odhcpd-ipv6only"
# Remove firewall and related packages

# Samba packages and LuCI interface
PACKAGES="$PACKAGES luci-app-samba samba36-server"
# disk related
PACKAGES="$PACKAGES block-mount fdisk gdisk e2fsprogs hdparm smartmontools"
# NTFS (to copy legacy drives)
PACKAGES="$PACKAGES ntfs-3g"
# rsync/rsyncd
PACKAGES="$PACKAGES rsync rsyncd"
# Editors and file managers
PACKAGES="$PACKAGES mc nano"
# Screen
PACKAGES="$PACKAGES screen"
# Other tools
PACKAGES="$PACKAGES htop"

make image PROFILE="wd_mybooklive-duo" PACKAGES="$PACKAGES" FILES="../files/" CONFIG_IPV6="n"

My files directory, also outside of the Image Builder directory, then contains some basic configuration (/etc/config/network with the interface switched to DHCP for example) and a few custom shell scripts on my MBL (for example I rewrote the original MBL firmware's monitorio.sh to have my disks sleep). But that's all entirely up to you and your specific needs.

I can then just download the current Image Builder gzip, ungzip into a directory, and from that directory call my shell script to quickly build a current image. I then sysupgrade using the resulting image and have my MBL going again, no reinstalling of packages and recreating config files needed.

A big THANK YOU, takimata!
This description is really extremely helpful.
I've already started to put something similar together, but your post makes it so much easier.
