When i tried to add new cronjob it shows the error that there is no space left.
sudo crontab -e
/tmp/crontab.jVOoWT/crontab: No space left on device
Your /tmp directory is full, first remove the files from your temp directory by issuing the command below
rm -rf /tmp/*
Run your crontab again
sudo crontab -e
Please execute df -i may be inode's 100% full Remove unnecessary file from /var
run your crontab again
crontab -e
I had the same issue on AWS and ultimately the solution was to boost the capacity of the hard drive. Solved the issue.

I'm using a DS4 Azure VM (Ubuntu 14.04). It comes with a 56GB local SSD.
I need to set up a 25GB swapfile in this local SSD. When I do df -h in the VM, I can see that it seems to be mapped to the /mnt/ folder. Following is the entire output:
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 29G 22G 6.4G 77% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
udev 14G 4.0K 14G 1% /dev
tmpfs 2.8G 472K 2.8G 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 14G 0 14G 0% /run/shm
none 100M 0 100M 0% /run/user
none 64K 0 64K 0% /etc/network/interfaces.dynamic.d
/dev/sdb1 56G 97M 56G 1% /mnt
However, if I try to initialize a swapfile in /mnt, it still gets added to the available disk space in /dev/sda1.
What do I need to do to set up my swap file? An illustrative example would be great. Thanks in advance.
I normally use the following commands to set up a swapfile:
sudo fallocate -l 25G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
Update:
I went into /etc/waagent.conf, and tweaked the followed:
# Format if unformatted. If 'n', resource disk will not be mounted.
ResourceDisk.Format=y
# File system on the resource disk
# Typically ext3 or ext4. FreeBSD images should use 'ufs2' here.
ResourceDisk.Filesystem=ext4
# Mount point for the resource disk
ResourceDisk.MountPoint=/mnt
# Create and use swapfile on resource disk.
ResourceDisk.EnableSwap=y
# Size of the swapfile.
ResourceDisk.SwapSizeMB=26000
After this, I resized (and consequently rebooted) my Azure VM from the portal. Currently I can't tell whether the settings have taken effect. Are my settings correct and what's the best way to ensure they've taken effect?
You are right, we should modify /etc/waagent.conf to add a swap file.
By modifying the /etc/waagent.conf file and setting the following 3 parameters a swap file will be created in the directory defined by ResourceDisk.MountPoint
ResourceDisk.Format=y
ResourceDisk.EnableSwap=y
ResourceDisk.SwapSizeMB=26000
Then we should restart walinuxagent:
service walinuxagent restart
Commands to show the new swap space in use after agent restart:
dmesg | grep swap

I resized my VM, and the swap file does not lose.
Are my settings correct and what's the best way to ensure they've
taken effect?
After modify the /etc/waagent.conf and restart walinuxagent, we can use swapon -s to check it.
I'm getting following error while doing tab. And unable to change the files, can open the files but not able to save the files. It looks like the server is working fine and long scripts are continuously executing and never ending.

What should I do now? I just deleted my unnecessary founders and files. Still the same error after some time.
I tried solving this issue and my tmp and log files are smaller:
ubuntu#ip-172-31-49-89:~$ du -sh /tmp
1.3M /tmp
ubuntu#ip-172-31-49-89:~$ du -sh /var/log
6.2M /var/log
Well, you said it yourself: you disk is full:
/dev/xvda1 50G 47G 0 100% /
Start investigating where you disk space is gone from the root folder:
du -hs /* | sort -h
That should give a pretty good idea what's occupying most of the disk drive.
I recently had an issue of disk space. More than 97% of disk was full. I cleaned the disk space by clearing the log files.The issue now i am having is the error in my api which says,
Incorrect key file for table '/tmp/#sql_42cd_0.MYI'; try to repair it.Below is the output of the df -h command i executed on the SSH
root#localhost:~# df -h

Other than this, i also tried running the myisamchk -r profiles.MYI in order to repair the .myi file but nothing seems to be working.
Sorted the issue. It was related with the incorrect join in the query.I do not understand, if the issue is related with the query then how does it echo the error Incorrect key file for table '/tmp/#sql_42cd_0.MYI'; try to repair it
Hey guys I am new to this Git and Linux..please can you let me know, how to copy data backup (here is backup.tar) to a new disk, as my root directory is showing 100%.

How do copy to disk3 and remove the backup from the old drive.
Downvoted because it's not a question about git per se, rather a question about Linux...
Anyway, use the mv command to move (or rename) files from one place to another. Or use the cp command to copy them then rm to delete.
Take a look at this tutorial for more help on how to move files around.
I am new to ubuntu , please help me i need create /data and mount this file system /dev/sdb
I have no clue as to how to do it . I read about mount and unmount , but I am still unable to create.

Can anyone please help me step by step.
Thanks
You need to create your mount point first:
sudo mkdir /data
Then mount the sdb1 (if sdb1 is what you want) to it:
sudo mount /dev/sdb1 /data
Done
PS: To check which one you want to mount run sudo fdisk -l
Follow these steps
1.Create a directory which you want that is mkdir /data
2.Then you will use mount command to mount /data directory to sdb1 which is like this mount /dev/sdb1
3.Then to take it immediate effect use this command mount -a
4.Then to check it you can use df-h
What about the following?
# mkdir /data
# mount /dev/sdb1 /data
If you don't have /dev/sdb<number>, you'll have to create partitions with e.g. parted or fdisk.
