Partition schemes
by GRS63 from LinuxQuestions.org on (#4TY26)
I would like some advice on partitioning.
Set up. Mother Board ASUS Prime Z390M-PLUS
32 GB RAM
1 Samsung 250 GB SSD M2 format (second one can be added)
2 WD 2 TB Hard drives.
Intended OS Fedora 31
What I was planning was a partition scheme as follows
on the SSD have,
/Boot
/
swap
Then have the two Hard drives configured as a RAID with
/home
/var
/temp
and a number of data partitions like Videos, Music , Papers, Data etc.
The Raid would be set as per the partition application that comes with the fedora install.
Can such an arrangement be done?
What do I need to set the SSD partitions to LVM or standard partition
What about the secure boot?
An alternative arrangement would be to put the two Samsung SSD in and set them as a raid configuration as well as the two hard drives, so there would be two Raid arrays.
In this configuration I envisage he set up as;
Raid array 1
/boot
/
swap
/var
/temp
and on Raid 2 would be
/home
/Video
/Music
etc.
Having said that however I would prefer to have /var and /temp on the Raid 2 array just because I have read that SSD's can have some issues with a lot of reads and writes.
Complicating factors I do not fully understand
1. Is it better to set the Raid 1 Array up using the Intel Raid configuration that comes on the mother Board. In other words activate the two SSD M2 units as RST active in the BIOS. What else do I need to change in the BIOS and are there any implications are there for Secure Boot or BIOS Boot (basically nothing in the motherboard manual).
If the Raid-1 array is set using the mother board what do I need to enter the /boot /, swap and other partitions, if I put them on the Raid 1 array as using the Fedora partitioning app. LVM, Standard partition or ?
Have not found it easy to find definitive partition set up information wit Raid arrays and various combinations of single and Raid arrays.
My thoughts as to having a non raid for the operating system and a raid for the data like /home etc is that the OS can be replaced but the data can not so having a Raid with a copy of the data on it gives some additional back up to the main backup.
As an aside, in a previous set up I found the /var partition got full. It was 10 GB, in size as seen in some recommended partition schemes, However I found that there was not sufficient space for doing an update especially if one has flatpak applications installed. In the partition scheme above I am looking at setting the /var partition to 25 GB.
Finally what are the thoughts on having /var and /temp partitions on an SSD. As I indicated above have read that because /var and /temp have a high number and read write cycles it is better to have there partitions on a hard drive. Something to do with the way an SSD deletes and writes information.
Anyway be interested in the thought on these matters. Thanks
