I know these are some pretty basic question but I come from the Solaris world and am fairly new to RHEL_ES/AS Linux, can someone answer some easy questions?

-I haven't found any information on how to download patches, whats the process and where can I find the patches?

-I also haven't found any information on how to install patches in RHEL can someone explain how?

-Also are there any patch bundles like Sun Solaris has its sets of recommended patches that you can download all at once?

-I've inherited alot of servers running the LVM software and I get the distinct feeling that there is some kind of issue running it from talking to other SA's but no one has mentioned any specifics.
If we don't use LVM then how can we extend a filesystem once it runs out of room?


Thxs in advance

Typically for RHEL you would use Up2date with the Redhat Network...

https://www.redhat.com/rhn/
https://www.redhat.com/rhn/rhndetails/update/

unless you don't have a subscription, then....

Patches are usually applied to source code, after which that code is compiled (and perhaps installed them). If you're working with binary packages, your only option is to see if newer packages are in the reposity and install them from there. That means basically monitoring your package manager application, in this case Up2Date I guess.

You can extend your filesystems by having backups which you surely have if it's important data, then bying more physical storage, making bigger filesystems on them and then putting the data back. That's the rough way. Or you can just use LVM if you like - if there is no problem, then there is no problem. If there is, somebody should notice it and complain about it.
