Hi all,
because I was not registered when I sent this message here at the first

I have computer with 3 hdds. One is ssd, 2 others are hdd. I want to
install Debian 10 to all 3 disks as one big system. What to use, raid or
lvm? I found an issue with lvm, when I want to create lvm, it shows you
can use $minsize and $maxsize, but all disks are 512, Gb. I want to
start with the ssd, it is sdc device. I know, how to create the lvm with
textual installer, but I have problem expanding it to next two hdds,
/dev/sda and sdb, so I am doing something wrong. I want to use all data
in one lvm partition, so / for everything.
Can you help please?
Thanks,
Pavel
You are describing JBOD:
https://en.wikipedia.org/wiki/JBOD
I have done JBOD on LVM. See lvm(8).
I have done RAID1 on mdadm; I believe mdadm can do JBOD, See mdadm(8).
If this is a new install, you should be able to achieve either or both
via the Debian Installer by selecting manual partitioning.
But, as others have said, two HDD's and one SDD in JBOD (or RAID) is not
optimal. Without specifics such as anticipated usage, data storage
requirements, drive makes and models, available drive bays, HBA/
motherboard makes, models, and available ports, etc., it is difficult
to make recommendations. In general, I put boot, swap, and root on one
small SSD and put bulk data on RAID large HDD's.
