Why using find and zip gives zip I/O error?

anmac1789 · 05-24-2023, 07:37 PM

Hello, I am using a webdav server pro from the olive tree to mount my galaxy s8's internal storage. When I try to zip a folder using this command

Code:

find ."/sdcard/DCIM/Camera" -exec zip -0 -r "/home/ubuntu/Documents/test.zip" {} +

I receive an error saying

zip I/O error: Bad address
zip error: Output file write failure (write error on zip file)

please see the attachment

Why?

I guess it is a disk full or something similar. Or probably a permission issue.

This could be caused by insufficient space on /tmp, try issuing 'export TMPDIR=<directory with lots of space>' before running this command or use tar since you are storing anyway.

how do I change permission or change the storage space of /tmp ? is this done in terminal ?

Could also be that the device is mounted read-only, or a permissions issue (as noted by others). But I'd also examine the command-line you're using...the find command is only going to find you a folder called Camera...and if you know you want to zip EVERYTHING from that folder, why bother with a find (since you know the location)? Why not just type in

Code:

zip -r /home/ubuntu/Documents/test.zip /sdcard/DCIM/Camera/*

Using zip also fails and gives me the same error hence this os why i want to know why it fails — for both find and zip
I can copy files to and from the android device when its mounted as a network webdav share because i already tested it with a small sample file. How can i change the permissions and for which file or folder specifically ? os it a global permissions issue on a vm ?

I try to see how much the temporary folder is being used using this command

Code:

df -h /tmp

you ought to run that df when the error occurred, which is impossible. You might try strace -o /tmp/strace.out -f zip .....
and check /tmp/strace.out to see what call caused that i/o error.

please see the attachment. Even when using -type d switch, find still tried zipping a file instead of just the folder. Something seems broken. I've also added myself to the vboxsf users group. I'm not sure what the 992 means. Is there a higher level of permissions than 992 ?

df -h /tmp gives me:
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 99G 34G 61G 36% /

since I've increased virtualbox total hdd space from 50 GB to 100 GB

I can't find any error in that strace log.

Can you try from your end using your virtual machine and see if it works for you. I know there is something wrong but I dont have deep knowledge about linux. How can I diagnose when and where this error is occuring and how do I properly use strace for this instance? Maybe instead of a virtualisation it needs a proper linux install on a seperate hard drive to use the find command? Funny thing is, I installed linux mint on vmware and tried the same thing, I am still getting the same type of error

pan64 · 05-26-2023, 01:28 AM

No, I can't reproduce it. But you need to execute the full command, like this:

Code:

strace -o /tmp/strace.out -f zip -r /home/ubuntu/Documents/test.zip /sdcard/DCIM/Camera/*
                             ============================================================  << this is the original zip command

And you need to check the file strace.out, and look for i/o error inside. Do not post the full file here, that will be huge.

Are you saying that you don't get any error or that you don't want to try it ? lol..

pan64 · 05-26-2023, 02:17 AM

To be able to reproduce it I need to recreate your environment, and 1. I don't know it, 2. I have no virtualbox.
But anyway, it is quite obvious something is incorrect in your setup and I have no any chance to [re]produce the same situation without knowing it.

Well for one thing, if you'd like to know my setup is done with ubuntu 23.04 on virtualbox with basic settings and using webdav server (https://play.google.com/store/apps/d...hl=en_US&gl=US) and then setting the home directory on the app to the root. Then on ubuntu vm --> other locations and using the ip address that's displayed on the app to set up a webdav connection. For me on the app it says

WebDAV server available on:
http://10.0.0.132:8080

Home directory: /
Password disabled

on ubuntu I connected the android phone with dav://10.0.0.132:8080 and opened the root folder with "open in terminal"

Another possibility is if you'd like to set up a microsoft teams meeting with me and see it that way which is alot faster.

Btw, which working directory am I supposed to be in to execute this command

strace -o /tmp/strace.out -f zip -r -0 /home/azeem/Documents/example.zip /sdcard/DCIM/Camera/*

Maybe this will help:
