You don't even need dd_rescue or something for RaspberryPi creation, you may use https://github.com/aktos-io/dcs-tools#cloning-a-target-into-a-new-target Jean-Denis Girard , 20 Eki 2018 Cmt, 22:00 tarihinde şunu yazdı: > > Le 17/10/2018 à 20:43, Henk Slager a écrit : > > On Thu, Oct 18, 2018 at 6:04 AM Jean-Denis Girard > > wrote: > > This looks like to have a similar root cause as this: > > https://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg81536.html > > Yes, seems similar. > > > For 50 clones, you could prepare 1 master (sparse) image and change > > the UUID with btrfstune for every SD-card you have after written the > > image (optionally sparse write with e.g. dd_rescue). > > Thanks for suggestion, I may try this another time, but I can live with > my workaround. > > > But it looks like some change is needed in the kernel code, although I > > have no clue at the moment where exactly. > > Right, this is why I send this message, try to motivate a dev to look at > this issue ;) > > > Thanks, > -- > Jean-Denis Girard > > SysNux Systèmes Linux en Polynésie française > https://www.sysnux.pf/ Tél: +689 40.50.10.40 / GSM: +689 87.797.527 > >

Right, this is why I send this message, try to motivate a dev to look at this issue ;) Thanks, -- Jean-Denis Girard SysNux Systèmes Linux en Polynésie française https://www.sysnux.pf/ Tél: +689 40.50.10.40 / GSM: +689 87.797.527

But it looks like some change is needed in the kernel code, although I have no clue at the moment where exactly.
Untar on empty partition returns ENOSPACE
Hi list, My goal is to duplicate some SD cards, to prepare 50 similar Raspberry Pi. First, I made a tar of my master SD card (unmounted). Then I made a script, which creates 2 partitions (50 MB for boot, 14 GB for /), creates the file-systems (vfat and btrfs, default options), mounts the two partitions: mount $part2 $mnt -ocompress=zstd,space_cache=v2,autodefrag,noatime,nodiratime mkdir $mnt/boot mount $part1 $mnt/boot When untarring, I get many errors, like: tar: ./usr/lib/libreoffice/share/gallery/arrows/A45-TrendArrow-Red-GoUp.png : open impossible: No space left on device tar: ./usr/lib/libreoffice/share/gallery/arrows/A53-TrendArrow-LightBlue-TwoDirections.svg : open impossible: No space left on device tar: ./usr/lib/libreoffice/share/gallery/arrows/A27-CurvedArrow-DarkRed.png : open impossible: No space left on device tar: ./usr/lib/libreoffice/share/gallery/arrows/A41-CurvedArrow-Gray-Left.svg : open impossible: No space left on device Which usually results in unusable SD card. When the first errors occur, less than 1 GB has been written. I tried to change mount options, especially commit interval, but still got ENOSPACE. What I ended up doing is limiting write speed with: xzcat $archive | pv -L 4M | tar x (with -L 5M I start to get a couple of errors) Is there a better work around? Or a patch to test that could help? The machine that runs the script has: [jdg@tiare tar-install]$ uname -r 4.19.0-rc7-snx [jdg@tiare tar-install]$ btrfs version btrfs-progs v4.17.1 Thanks, -- Jean-Denis Girard SysNux Systèmes Linux en Polynésie française https://www.sysnux.pf/ Tél: +689 40.50.10.40 / GSM: +689 87.797.527
