Getting "Error code: 4 (Failure)" when uploading a file to CentOS using WinSCP

Question

I am using WinSCP from last six months almost regularly.

Suddenly i am facing a issue that is, I am not able to upload a file in server using it.

Its throwing below error message:

General failure (server should provide error description).
Error code: 4
Error message from server: Failure

Common reasons for the Error code 4 are:
- Renaming a file to a name of already existing file. 
- Creating a directory that already exists.
- Moving a remote file to a different filesystem (HDD).
- Uploading a file to a full filesystem (HDD).
- Exceeding a user disk quota.

I google about the issue and found that it might be due to 100% full filesystem.

I checked the memory using below command in centos:

free -m

Output of the command:

              total        used        free       shared  buff/cache   available
Mem:          32014       28612         310        1553        3091        1533
Swap:             0           0           0

It seems like that i have 1533 MP space available. But still i am not able to upload a small 1 Mb file.

df command output:

Filesystem     1K-blocks     Used Available Use% Mounted on
/dev/vda1       52416860 52416840        20 100% /

tmpfs            3278268        0   3278268   0% /run/user/0

Can anyone provide any info in this regard.

Solution

So it seems that your file system is indeed full: Use% is 100% for file system /dev/vda1, which should be used by the /home/centos path

On CentOS run lsblk and then when you find the partition, etc. in question where the files are uploaded on the FTP server, run df /boot for example where /boot will be the actual mountpoint in question. The filesystem and memory or swap is not the same thing. Also be sure something else is not moving files from the server like an internal process as I've seen that sort of thing cause this type of problem if I recall correctly. You can probably just run df -all to see everything on the filesystem.

I have already wrote you on Stack Overflow: When re-posting there [on Super User], make sure you include a main error message (what you have posted are just additional details of the error), or even better a session log file.

[davidgo]

Use the "df" command to show the amount of free disk space. The free command doesn't help as it shows RAM.

[Vishal]

@MartinPrikryl I have added the log,

[Vishal]

Is there any way to can found the main storage file, it can't delete the everything in centos.

@Vishal This is Q&A site, not a forum. You asked one specific question, you got specific answer; if it answers your question then please accept it (click the tick on the left). If you have another question then ask a separate question. But do your research first; I'm pretty sure there are already questions about investigating disk usage.

@KamilMaciorowski Thanks for your information
