Did we need a hotfix or workaround or quick update (roolback) in xcp ?

thx 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

@foreverska witch one do you find with XCP?

@foreverska did you use 2 Grafics ?
I try some two with one and internal was not working but with a second small one it was fine or try a other PCIe slot first

@olivierlambert

THX Olivier

looks like it Working
I hope i can build a Coreboot with a Supermicroboard

Hello

I like to try using Coreboot as a other "Bios/uEfi", did anybody try this before ?

I am using a Thinclient for my XCP Servers. Real small and cheap (if it is used) HP T620 with a 64G M2 SSD and 4 GRam Quadcore AMD CPU. To backup some VM i use a external USB3 HDD. It is running very nice and smoth. Power is between 5Watt an 20Watt excluding the USB Harddrive.

My coutumer had mostly two Servers and a Thin client.

my own Thinclient is used as a server for FHEM Homeautmatisation

Whats about XCP-NG ?

thx Axel

Now i am moving a step forward :-). I dont let XO runing in a VM my XO is running on a Thin-Client (HP620 16GSSD and 4GByte RAM 1GBit Nic) with Debian. The Debian installation was a lill bit tricky but now its running. Thanks for the debian / ubuntu install script is running perfekt.
The USB3.0 HDD is connectet and mounted on /Backup.
Reading from USB drive with dd

dd if=/dev/sdb1 of=/dev/null bs=100M count=10

Result 130MByte/sec

Debian and XO needs fresh 1,7Gbyte HDD-Space.

My XCP-NG servers are found with there VMs

Next step testing Backup ...

thx Axel

great work an gratulations
I am gulty loaed more than one times

Hello Olivier

I like the Nethserver its based on CentOS and its a nice Groupware. With CentOS i am fiting very often to Install them.

Whats about the BSD unixes ?

Hello Olivier

Thx 4 the Infos.
So i will seperated in two parts the Web Interface and the managment network. Had only to do with safty ..

Hello

a simpel compicated question
First I try XO with debian (not in a VM) that was very nice, but the test was very smal with a USB3 HDD and a Thin-Client as a Server. The Base was Debian 9.9. It works very fine and with the new compression fast

Now i will use it more professional, with a older server. With three networks one for the BMCs, one for web-Interface and one for the comunications with the XCP-NG servers.

• Did make it sence to use more networks ?

• list itemIt is possibel to seperate the networks?

• Did make it sence to use 10G for the communication with the XCP-NG Servers

Thx Axel

I am starting Knoppix 8.2 and taht was running, bit i am not shure about the SAS/Raid Controlle.
all other parts are found. I will send some Infos next week when i was in my office

Hello

my hope is that somebody testet a Appel server with xcp-ng . Now i am a admin in a university siche first of July. I the store was a Apple Server/workstation and a SAS controller. Can be a nice testing platform

Hello
I get the same problem but with a fresh install. With Debain 9.9. it was okay. Netinstall with ssh server nothin g elese. Than install with apt-get install curl. and using the script. Everyting is running fine.
Same Way with 10.0 no web interface, and i cant find a error in th bash ..
looking mostly the same like 9.9

thx

I hope i can try it next time again ..

Hello stormi

Thx for your info i will try your pre release next few days

Hello

now it looks like 8.0 will be ready soon. I like to write a article for a big german IT magazin
