Re: Hidden files taking up disk space

Dear KT53

The abrt features I left disabled for not having utility.
In my case, it was the files that were deleted but were still being used by processes.
Your tip was valuable.
Thanks for your help and collaboration.

Re: Hidden files taking up disk space

Dear TrevorH His tip was perfect. Several files that were deleted were still being used by processes. Very grateful for your help! Hugs! Most likely it is space that was being used by large files that you have already deleted but those files are still open by the process using them. They don't get d...

Re: Fix file system metadata I/O error

Hello guys,
I got support and started the system through a livecd.
I have successfully performed the XFS system repurposing.
The only way to repair the system is to run the commands, where the disk is not mounted.
Thank you for your support.
My greetings!

Re: Fix file system metadata I/O error

I understand it would be easier to use a livecd or liveusb boot disk. In the clouds structure I use, I do not have access to boot from a removable media. When trying to delete a directory, I get the following error: rm: cannot remove â*â: Structure needs cleaning # rm -rvf Interwiki/* rm: cannot rem...

Re: Fail2ban does not send email

I believe the problem is in authenticated smtp.
Could someone tell me how I set up an email account with authentication?

Re: CentOS 7.5 firewalld config changes

I'm also going through the same problem. When restarting the server, the firewalld is lost in zone settings. This started happening after I upgraded the system.
Currently Centos is in this version:
CentOS Linux release 7.5.1804 (Core)
Has anyone found a solution to the problem?
