[SOLVED] A question about file and directory permission

Jason.nix · 02-06-2024, 12:31 AM

Hello,
I created a directory and two files under the /var/log directory. I want V2Ray to be able to write something inside these two files. So, I changed the file permission as below:

Code:

# chmod -R 777 /var/log/v2ray/
# ls -l /var/log/v2ray/
total 0
-rwxrwxrwx 1 root root 0 Feb  6 01:20 access.log
-rwxrwxrwx 1 root root 0 Feb  6 01:20 error.log

But I get the following error:

Code:

v2ray[665]: 2024/02/06 01:21:11 [Info] v2ray.com/core/main/jsonem: Reading config: /etc/v2ray/config.json
v2ray[665]: main: failed to create server > v2ray.com/core/app/log: failed to initialize access logger > open /var/log/v2ray/access.log: read-only file system

How to solve it?

Thank you.

that is a read-only filesystem. You need to check why and fix that (if there was any error).

Yes, the error message is "read-only file system" not "permission denied".

Determine the file system with

Code:

df -hT /var/log/v2ray/access.log

For example, a type ext3 and ext4 file system is known to permanently fall to read-only if there was an error; the usual fix is a system reboot.

Hello,
Thank you so much for your reply.
Why did this happen? I solved this problem via mount -o remount / command.

you need to check the logs of the last boot.

Hello,
Thanks again.
Do you mean dmesg?

either dmesg or journalctl or /var/log.
