I have been wondering how to ask these probably basic questions related to a new server installation I did several months ago. It is running properly but I didn’t get the expected outcomes and many people may have these same problems: 1. I have 4 disks that I wanted to partition as two separate RAID1 clusters and after a LOT of tries (anaconda badly wanted to be a 4 disk LVM array) I managed to get something like that BUT what happened is I have one RAID1 cluster for every required directory (boot, efi, home…etc) what I expected was two RAID1’s with the directories spread around on them. I did preformat the disks that way but anaconda re-partitioned and reformatted them. I suspect if I get a disk failure I will have to do a fail/remove on every MD number on that physical disk before removing the disks??? 2. I would like to use automatic updating BUT I don’t want to have to reboot the server each time as I have to with my workstation. I know there is a way to do this BUT what happens when the applications software (eg PHP) has a deprecated function that gets removed? Do I suddenly get a crash with no obvious reason? How would you debug something like this? Will the automated updates pass across new versions - ie RL9 to a future RL10 without problems? 3. At the moment selinux is in permissive mode because I have installed a lot of third-party software, including a lot of in-house stuff. How can I find all the dependencies before turning it on? I bought a book about selinux and now I know less than I did before! I have a few more but these are top of the head right now. I’m sure there is documentation somewhere but I’m not a professional sysadmin, I only do it because nobody else knows how and it’s sort of fun; if you think these questions are trivial please just tell me so and I’ll go away. ---

> [@johni](#): > > anaconda re-partitioned and reformatted them. In the installer one section is storage. There one can choose which drives to use and choose between _Automatic_ and _Customize_. The former is the default and I always choose the Customize. That gets me to dialog, where I can remove and add filesystems as I please. That has also “create automatically” that creates default filesystems, but one can modify the set before choosing “Done”. One even gets a summary of what will be done on install, with option to reject and change choices. > [@johni](#): > > badly wanted to be a 4 disk LVM array) The default does indeed use two “standard” partitions for /boot and /boot/efi, and one VG, where LVs for /, /home, and swap are. In the Custom one can switch between standard, LVM (and “thin LVM”?). * * * I don’t use automatic updating, but I’d guess there is a service that can run “dnf up” on schedule and does not reboot. Some packages, like kernel and glibc, do need reboot to get into use. > [@johni](#): > > what happens when the applications software (eg PHP) has a deprecated function that gets removed? A core idea of Enterprise Linux is that features are not removed. That you can set up a service and it can run up to decade. > [@johni](#): > > Will the automated updates pass across new versions - ie RL9 to a future RL10 without problems? The RL10 will not be a “new version”. It will be a distinct distro. Yes, there are distros that allow conversion to similar distros, e.g. Fedora N → Fedora N+1, and Ubuntu to Ubuntu, but Enterprise Linux has not been such. There might become third-party tools for _in-place conversion_, but Rocky has no support for them. (Cannot predict future, obviously.) * * * > [@johni](#): > > selinux is in permissive mode The SELinux does log events in permissive mode that would have been blocked in restrictive mode. One can see summary of those events with: `audit2why < /var/log/audit/audit.log` ---

Jlehtone: thanks, that provides enough information that I can probably find what I need. During installation I always select “custom” for the disks because I always, so far, install as RAID of some sort. I wasn’t aware that different release versions were considered different distros. That is important to know I think - it seems to imply that when the RL9 finally expires I will need new hardware to install on so it can be run non-stop. Can I assume that something like PHP will be modified by Rocky/Red Hat so deleted functions remain for the life of the distro then? What I had in mind is something like: > **[How to Set up Automatic Updates on Rocky Linux / AlmaLinux](https://linuxiac.com/how-to-set-up-automatic-updates-on-rocky-linux-almalinux/)** > > This article shows how to set up the dnf-automatic service to apply updates automatically on a Rocky Linux or AlmaLinux system. Thanks for the selinux info - that was not in the book that I bought and seems crucial! One more unknown - smartctl doesn’t give the correct interpretation of the data on WD Blue SSD’s and I have done a dnf upgrade to the current release. Is this a bug in smartctl or the disk’s own databases? ---
