Unlike earlier chapters where end users were reporting the issue to us, this time around we have found an issue for ourselves. While performing some daily tasks on the database server we attempted to create a database backup and received the following error:
[db]# mysqldump wordpress > /data/backups/wordpress.sql -bash: /data/backups/wordpress.sql: Read-only file system
This error is interesting because it is not necessarily from the mysqldump
command, but rather from the bash redirect that writes to the /data/backups/wordpress.sql
file.
If we look at the error it is very specific, the filesystem we were attempting to write the backup to, is Read-only
. What does Read-only
mean?
