Only issue is VNC is ONLY accessible with the sysrcd running if that matters. Sorry just never had to go through all of this.
Ouch that complicates things. I guess the statically linked qemu approach people use to install windows would still work but sadly it's more complicated. Still not impossible i guess.
Basically it should go like this:
mount -t tmpfs -o size=2000m tmpfs /mntcd /mntwget %URL-OF-CENTOS-ISO%wget -qO- /tmp https://ia601503.us.archive.org/12/items/vkvm.tar/vkvm.tar.gz | tar xvz./qemu-system-x86_64 -net nic -net user -m 1024M -localtime -enable-kvm -cpu host,+nx -M pc -smp 2 -vga std -usbdevice tablet -k en-us -cdrom /mnt/%NAME-OF-CENTOS-ISO% -hda /dev/sda -hdb /dev/sdb -hdc /dev/sdc -boot once=d -vnc :1This is a copy/pizza adaption of the windows install approach so no guaranties. Something is surely wrong. Also it assumes that you can conenct the rescue system from the outside (it is not firewalled or anything) and that your drives are actually /dev/sda (probably the SSD), /dev/sdb + /dev/sdc (the raid).
I dont have any rescue mode other than sysrcd which already has vnc access. That is it. The provider is limiting in this way
Tbh i don't know sysrcd but i guess it's as good as any other rescue system.
Its accessable via VNC and SSH by default and has a GUI with a few preinstalled apps in the GUI. Its more of a bootable ISO.
Ouch x2. No way to drop to a shell?
Theres the GUI terminal if that counts?
Sure that should do it. Hopefully the CD has mount, wget/curl and tar though otherwise it gets even more tricky.
Can you ping your servers IP while the rescue CD is running?
Yeah
Nice it probably is connectable from the outside. Might be worth double checking by running
nc -vlp 33445and trying to connect from the outside but if it pings im 99% positive that would succeed anyways.So only question left is how to fix the network after install. Can you post the output of
ifconfig -a? I know it sucks from a graphical terminal...Edit: Of course mask your IP and
route -noutput please.Edit2: That's basically to find the IP/netmask/gateway settings to be restored later so you know these already you can skip this.
Edit3: Could also be done from a normal system. Doesn't have to be done in rescue mode.
I'd be happy to do this for you if you want to send me your information in a PM. This thread doesn't need to be this long.
We've already tried that yesterday. Problem is there is no KVM support (not 100% sure if it's because the rescue CD does not include the kernel module or the CPU does not support it) making Qemu dog slow.
In 1h of running it managed nothing but print a bunch of boot message so if you have some better idea and he's OK with that i'll gladly leave it to you as i fear that even if it eventually gets to the installer it might not be usable or at least take years to install.
You don't need a KVM. Boot with sysresq, decide device names, edit fstab.
Seriously, if you're still having a problem - PM me with credentials after it's on sysresq, and I'll try to fix it. I won't reboot it so you can go back through the history to show there's nothing malicious.
KVM isn't needed. Just device paths.
@WSS it's fixed afaik. Btw the fstab mount was working anyways.
@mksh Well, OK, then.
@WSS
Ah that's nice. And they said you were a mean guy...
I used to think that, but now I'm pretty sure @WSS is simply allergic to stupidity.
Thats what he wants us to think of him. He is a good chap.
