Updating redhat 7 3

To update the system you will need configured repositories that act as the source of the updated software.If you sit next to the machine that is running the operating system to be updated, you can easily act if something goes wrong during update, like checking the output on the terminal, or boot to a live system if the upgraded one does not return from reboot - but this is not always the case.database that contains all the metadata about packages installed on the system.The update process also calculates all dependencies of the upgraded packages, may replace old packages, and remove old kernel images according to its configuration.To get this valuable information we can run the update process as it would run the actual update, but stop before any actual package downloading, installing or updating have taken place.

So filling up the volume they are writing to is a bad thing.

From the process described above we could guess that we need some disk space for the update process: directory.

Needless to say that if there isn't enough space to store all data needed, the update process will fail.

As yum will update everything it can find updates for, we may want to remove unneeded packages beforehand.

We may also notice a package marked for update that we are version-locked with that need to be excluded from the upgrade.

This can only happen at the metadata, or the new rpms download stage, and will not break the system.
