Next Version of Install process with Partitions and RAID 0 to 6

axel

Hello Guys

first you steps to integrate RAID 1 device wide is a nice step and was helpfull to integrate my RAID 5 and 6 Partitions. I am sorry i am talking about soft RAID with the mdam tools.

It ist not so esay to fix a broken device wide RAID 1 (mirroring) when no harddrive is broken. That will a split brain problem, which one is okay.

But now a breake and move over to the partitiontable.

Number  Start (sector)    End (sector)  Size       Code  Name
   1        46139392        83888127   18.0 GiB    0700
   2         8390656        46139391   18.0 GiB    0700
   3        87033856       937703054   405.6 GiB   8E00
   4        83888128        84936703   512.0 MiB   EF02
   5            2048         8390655   4.0 GiB     0700
   6        84936704        87033855   1024.0 MiB  8200

That is my table have a look on the patition types.
1,2 and 5 had the typ 0700 that is NTFS by standard.
Number 1 is the root file system with ext3
Number 2 is the backuproot file system with ext3
Number 5 is the /var/log file system with ext3
It will be nice that the filesystem use 8300 if it is a non RAID partition

After nomal installation the big patition for the SRs ist type 0700 to. So ich change ist to 8E00 thts the one for Linux Logical Volume Manager (LVM) partition. If you use ext4 it will be 8300.

I know this "other" types had tradition from Cytrix, but it looks like a absolut beginner and build the first partitiontable ever with Windows.

Next thing the intall process is creasy, but i do not know why. I never had success with a installation on a used HDD with GDP partitiontable. Normaly i start wit Live Linux and a dd if=zero of=/dev/sdX bs=200M to distroy any kind of data. Did anybody knows what the devil the install proces is doing to stop when an non XCP/Xenserver GDP partitiontabel in on the disk.

So i try with a big part of the success to buiel a system with 4 HDD and a softRAID 6 on the SR partition root is RAID1 and /var/log
is a RAID6, swap is a RAID 0 but on swap level kernel bild it by them selfs if like. Whats missig that the maschine can start with the second HDD when the first one is gone.

What is real sad i an not make some major updates with release changes. The systems works with 8.2 very fine, but must reinstall mostly when a new versin is coming.

I this solution the SoftRaids are builded by partition with the correct partition type fd00.

If the comunnity likes to have an better or mor modern install and upgrade process. I will try to build it but i need a lill bit help to understand the old one.

If not i get some more free time to learn Rust ..

ths for your eyes, time to read this. I will hope we had a interessting discussion

thx a lot for the support the community and the fabules XCP-NG team

best wishes Axel
