I am unzip file of 35.8 GB and have a 1.7 TB space in my Virtual machine to extract zip file. Also, I already give all security permission to execute it but still stuck on no space left

I am getting this error "OSError: [Errno 28] No space left on device" when I am writing files in a directory. I am downloading images programmatically from different sources and creating directories according to day wise. Its working well on windows though.
While checking inodes I got this
I tried different solution like deleting the deleting the junk file and tmp folder but still no success.
What could be the issue?
inodes don't directly correlate with disk usage. Better use df -h to actually see, if your drive is full.
But as you get the error: Yep, it's full. Up to the brim.
You probably have some data some where that uses all that precious storage. Check your home directory with du -hs * | sort -h. This can take a moment, but it will show you the size of all files and directories in the current workdir (and sort it too).
Also directories to check would be /opt, /var and /tmp. Don't randomly delete stuff in /var though, if you don't know what you are doing.
I've listed /tmp here too, because you don't have listed it as a mount of the type tmpfs. You should fix that probably.
How can mount a partition in an already existent folder of my linux tree? What happens with the already created file and can I move these to the new disk in the process?
I am using a Ubuntu 16.04 with an SSD and HD disk, I would like to mount the ~/Documents or $HOME in the HD moving the files already created and free the SSD to the main files of the operation system (in this moment all the files are in the SSD and the HD is only formatted as Ext4).
The moment you mount the new parition on top off ~/Documents you cant access the Files anymore, but there are some Options:
Mount the HD somewhere else first and move the files. (code is just an example, it is not supposed to be executable as is)
mount /dev/disks/by-lable/foo /media/temporary
mv /home/hildogjr/Documents/* /media/temporary
umount /media/temporary
mount /dev/disks/by-lable/foo /home/hildogjr/Documents
Use a bindmount, to still be able to access the files after mounting:
mount --bind /home/hildogjr/Documents /media/Documents_on_ssd
mount /dev/disks/by-lable/foo /home/hildogjr/Documents
mv /media/Douments_on_ssd/* /home/hildogjr/Documents
umount /media/Documents_on_ssd
Use a unionfs, and move the files over Time. man unionfs:
It first tries to access the file on the top branch and if the file
does not exist there, it continues on lower level branches. If the
user tries to modify a file on a lower level read-only branch the file
is copied to to a higher level read-write branch if the copy-on-write
(cow) mode was enabled.
I have a vm(on vmware fully running). But i want to do some modification and put all file system to single partition /.
In my current VM i have /, /var, /tmp, /boot partition.
Action performed:
Attached new hard disk, formatted and created two partition (one for / and another for swap)
made / as active partition for root.
copied all the files from original hard disk to new harddisk.
made changes in /etc/fstab and run grub-install.
detached new harddisk and created new VM using this harddisk.
Now when I am starting VM, I got
"Error 15: File not found"
Just got answer while hitting and trying . This error is due to /etc/grub/grub.conf file. When we have /boot partition we don't need to give whole path for kernel for example :
Kernel /< kernel version>
but when we have single root partition only, means no /boot partition we need to provide complete path, example:
Kernel /boot/< kernel version>
And same for initrd line.
It worked for me.
I want to backup my NAS on multiple DVD's. What i had in mind was a script what does the following:
-Create a folder for each DVD
-Copy the files and filestructure into the DVD folders
-Stop / goto next DVD folder when the first DVD folder is full
i.e. the trigger is 4 GByte (which calculates easy for the example)
I have a datasrouce with 10 gb of data., so this will be 3 DVD's. So the script first create three folders: DVD-1, DVD-2 and DVD-3. Next the copy will start to copy 4 GB to the DVD-1 folder. After that, the remaining files must come in DVD-2 and DVD-3.
As far as i know, rsync and cp doesn't bother about calculating this. I know it is an option to do this by using archives like zip, tar or gz but at first i want to try it with unpacked files.
Is all above an option with standard Linux bash commands or is it insane?
No, there isn't any standard tool that does this out of the box. But it's pretty simple to code up, and there are a few projects to do it:

Here is the thing
I have a server with total 85 GB disk space and right now i have a folder with the size of 50 GB which is containing over 60000 files .
Now i want to download these files on my localhost and in order to do that i need to tar the folder but I can't tar the whole folder because of disk space limitation.
So i'm looking for a way to archive the folder into two 25 GB tar file like part1.tar and part2.tar but when the first part is done it should wait for asking something like next part name or permission or anything so I can transfer the first part to an another server and then continue archiving to part2. Or a way to tar half of the folder like first 30000 files and then tar the rest.
Any idea? Thanks in advance
One of the earliest applications of rsync was to implement mirroring or backup for multiple Unix clients to a central Unix server using rsync/ssh and standard Unix accounts.
I use rsync to move compressed (and uncompressed) files between servers.
I think the command should be something like this
rsync -av host::src /dest
rsync solution was good enough but i found the solution for main question:
tar -c -M --tape-length=30000000 --file=filename.tar foldername
After reaching 29GB you will need to change the tape(in my case transferring the first part and removing it) and hit enter for continue.Additionally it is possible for give next parts name:
Prepare volume #2 for `filename.tar' and hit return:
n filename2.tar
Because it is going to take time i suggest using screen session over SSH :
