@scottalanmiller i use centos initially, but now im playing around with fedora as you recommended. so far so good.

@scottalanmiller I have 2x8TB desktop u know lots video and stuff

@scottalanmiller How does they make money on such cheap pricing?
50$ / year and unlimited.

If everyone upload 10TB of data wont they loss money?

and T&C applies???

@tim_g manage to install cockpit, but the storage menu wont show up. It is on centos 7 - xen dom0 .
Any idea how to show the storage menu?

It is working well in my fedora 26 in my laptop. I have the storage menu.

No, I dont have that unit. I just came across article online and someone manage to IT mode H310.
You looking for the unit for testing? will bump you if i find it.

@tim_g said in What LVM GUI to Use for Remote Linux Machine:

Cockpit

cool... will research on that...

@tim_g yes, it is PERC 3xx which can be set to IT mode if I read it correctly.

@scottalanmiller yes thats what i think of. so @Francesco-Provino statement is incorrect? : One last thing: raid 1 on standard SATA hdd is gonna be slow. Quite slow.

AFAIK, RAID 1 will improve read 2x ? maybe slower write but not so much?

CMIIW.

Thanks.

@scottalanmiller i mean i want to experiment between perc and sw raid to learn the diff... so i guess i dont have that option to play around...

ok will give it a shot after i give up with fedora
maybe will try centos also as i am abit more familiar with centos. I also feel there are more online reference for centos compared to fedora. maybe it is just me

@francesco-provino I guess i have no choice for data sake protection. Do have any other choice? What is the best option for me?

thin lvm / cow is for sharing storage right purpose on limited disk right? by saying slow down A LOT, may i know roughly how many % slower based from you experience?

@francesco-provino

Am i right to say better to just use the whole array on the host and locate it to root partition? and use file image instead for flexibility?

Hi,

I have been playing around with Fedora 26.
So far lots of challanges

I got multiboot error like following : https://bugzilla.redhat.com/show_bug.cgi?id=1286317

I use latest xen with latest fedora.
(dell r720 server with eufi boot)

Anyone have step to step guide for newbie like me?
Trying to follow but cant quite get it. I have limited knowledge in kernel and grub.

Thanks

1. Setup RAID-1 via PERC for 2 x 4TB HDD
2. Install Fedora 26 Server from USB Boot
3. LVM only 20GB out of 4TB for Fedora VM Host (Xen/KVM)
4. Partition :
   1. root (LVM with xfs) 17GB
   2. boot (LVM with xfs) 1GB,
   3. swap (LVM with swap) 2GB

Please correct if my setup is fine. still learning

Should I partition 20GB and leave the free space for VM guest LVM? or I do 4TB during the install, and put VM host as image file?
CMIIW.

Thanks.

thanks.Will continue my experiment. I guess I stuck with PERC RAID then.

@francesco-provino do you know how to bypass the HW RAID in DELL R720?
I want to use SW raid instead with MD.

Thanks.

@francesco-provino i assumae your idrac is enterprise license? mine is express only sad... haha...
official price of the idrac enterprise license is 400$ ++ .... -.-

@francesco-provino said in Dell R720 Display problem with Fedora 26 server:

If I understand well, you are trying to install a full GUI in the hypervisor layer of your server. I’m sorry, but this is just plain wrong.
You should only install a bare minimum Fedora and KVM tools on bare metal, period.
The typical server is just not good with graphical stuff.

Don’t get me wrong, it’s great that you are experimenting a KVM environment, but don’t treat it as your old bare metal windows 2008 server.
Just to be clear, the right path to install and manage an enterprise server like the r720 does NOT include connecting any display, EVER.

First thing, you should use the management interface iDrac, that provides you vga-like and terminal access to the server on a web interface. You can even mount ISOs directly from your laptop, the time of burning cd/usb is over!
I’ve deployed two r740 this way two months ago, mounting the VMware ISO through wifi (!).

The other thing is, you don’t have to install any management GUI or tools in the bare metal system, ever. All the management should be done from another machine, that has the management stack. VMware (that I don’t love, but is the gold standard regarding some best practices) makes it clear from the beginning; no GUI, useless busybox on the host, everything is done through the management appliance (the vCenter).

Regarding Fedora, I use it for some of my server and the protocol is:

• install and upgrade the host OS with KVM and its tools;
• harden ssh disabling password login, enable ropt access or anther user that can became root (as of today you MUST use root to start the VM on the host, the user-based qemu connection is flawed in many ways including networking);
• install the KVM management layer (usually libvirt) and your gui of choice (virt-manager) into ANOTHER machine and connect those with the host via key-paired, passwordless ssh.

ok i think i get the idea. let me practice again thank you.

I have problem with starting the Linux desktop. it seems the display is not set properly.
still figuring how to set the display properly in x11.
