[SOLVED] Chromebook Linux freezes when using rsync

Middle.Earth · 09-23-2021, 03:46 AM

I have been using Linux Mint for several years and Debian before that.
I feel comfortable with the command line.

I bought a Lenovo 300e Chromebook over a year ago and have learned to like it a lot including that Linux on Chrome OS is a bit different.

I searched this forum for my topic but did not find what I was looking for.

My Chromebook Linux terminal freezes when I try to use rsync, I have waited as long as 30 minutes for an action. On my other Linux Mint machines I use rsync to backup both my local laptop drives as well as the Google drives of my wife and myself. Therefore, rsync is very useful and important.

This is my rsync syntax:

Code:

rsync -av ~/Documents/File.png /mnt/chromeos/removable/SDCard/Document
sending incremental file list
File.png

After this is just stops...

I have not yet tried a powerwash, as it is a pain to get things back to where I want them.

When the terminal stops, I can do Ctrl-C to terminate the process. Unfortunately, once I terminate the rsync process using Ctrl-C, various other commands such as cd, ls, etc. also stop functioning. When that happens they do NOT respond to Ctrl-C and I have to force close the terminal window.

If I Ctrl-C after rsync and restart the Linux container with sudo reboot OR shutdown the terminal window opens for a brief moment but then quits with this error message:

Quote:

WARNING vsh: [bus.cc(638)] Bus::SendWithReplyAndBlock took 26835ms to process message: type=method_call, path=/org/chromium/VmCicerone, interface=org.chromium.VmCicerone, member=LaunchVshd

If I shutdown and restart my chromebook I can then again do ALL of the following without error:

Code:

cd Documents/

cp ~/Documents/File.png ~/Desktop

cp ~/Documents/File.png /mnt/chromeos/MyFiles/Downloads

cp ~/Documents/File.png /mnt/chromeos/removable/SDCard/

cp ~/Documents/File.png /mnt/chromeos/removable/USBHDD/

However, again, when I try to use rsync to move the same file as the cp command above, the command just never completes:

I tried to find something in the following log areas but I did not find anything which made sense to me:
file:///var/log/
chrome://system/#logs
I am uncertain where else I may find any log information and if I do what to do with it.

If anyone knows of a fix for this problem or a comment if I am doing something incorrect, I would be grateful for your suggestions. Thank you

Hi.

I'd try searching the web for: rsync freezes

...I haven't had this issue nor dove too deep in it's man page?

It might be a memory issue, try adding the -z option for compression to your list; -avz

Tried that, same result but thanks.

I have been all over the web prior to this post searching for a wide variety of possible results. When I do a simple "rsync freezes" search the results are always relevant "normal" Linux, not to Chromebook/Chrome OS.

In a Reddit forum one reply stated "Note that SD cards are mounted noexec" so I looked around a bit and found the thread below, which said noexec was removed.

https://www.reddit.com/r/Crostini/comments/l6sjpz/current_dev_890438915_removes_noexec_from_shares/

When I do:

Code:

mount | grep 9p

I get the below indicating noexec is removed:

Code:

9p on /mnt/chromeos type 9p (rw,nosuid,nodev,relatime,sync,dirsync,access=any,trans=fd,rfd=26,wfd=26)

What I do not understand is why I can do cp or rm commands and they work just fine with all Linux shared volumes on my CBook but not rsync.

I finally solved my problem.
I use rclone to backup my Google Drive to my external USB or SD Card

I use rsync to backup all internal files to external USB

PROBLEM WITH RSYNC ON INTERNAL OR EXTERNAL LOCAL DRIVE BACKUP:
rsync hangs when using -a
For example:
rsync -avh /mnt/chromeos/MyFiles/Downloads/AASTUFF /mnt/chromeos/removable/MyUSBHDD/Backups

PROBLEM WITH RSYNC SOLVED:
rsync works when using -rvh WITHOUT -a
rsync -rvh /mnt/chromeos/MyFiles/Downloads/AASTUFF /mnt/chromeos/removable/MyUSBHDD/Backups

PROBLEM WITH RSYNC & GOOGLE DRIVE BACKUP:
When I attempted to rsync from Google Drive I got the following errors:
rsync: send_files failed to open "/mnt/chromeos/GoogleDrive/MyDrive/AASTUFF/mygdocfile.gdoc": Operation not supported (95)
"/mnt/chromeos/GoogleDrive/MyDrive/AASTUFF/mygsheetfile.gsheet": Operation not supported (95)"

I found that all other files and directories copied OK. The "Operation not supported (95)" seems to be a lack of permission to those files.

This site says in part:
https://webapps.stackexchange.com/qu...n-google-drive
"This does copy Google docs, sheets, etc in their original format, although it may go through a conversion from gdoc > docx/xlsx/etc"

I noticed in my Linux Mint laptop the rclone GDrive backup converted all gdocs and gsheets to docx & xlsx as the comment above says.

PROBLEM WITH RSYNC SOLVED USING RCLONE:
I used the procedure detailed here:
(https://www.howtogeek.com/451262/how...rive-on-linux/)

to install rclone:
sudo apt-get install curl
NEXT:
curl https://rclone.org/install.sh | sudo bash
THEN:
rclone config
------------------------
RCLONE
https://github.com/rclone/rclone
https://rclone.org/docs/
DRIVE DOCUMENTATION:
https://rclone.org/drive/
DOWNLOADS:
https://rclone.org/downloads/
-----------------------------
I used a command similar to this to successfully backup my Google Drive to my SD Card. It works with USB also.
rclone copy --update --verbose --transfers 30 --checkers 8 --contimeout 60s --timeout 300s --retries 3 --low-level-retries 10 --stats 1s --create-empty-src-dirs "MYGdrive:AASTUFF" "/mnt/chromeos/removable/SDCard/Downloads/AASTUFF"

I hope this helps someone. It was driving my crazy, I almost installed crouton before I stumbled upon using this.
