Hi.

actually, im having an OVH Dedicated server
So, I ACCIDENTALY turned on firewall, and It did such a mess.
So, i went into rescue mode.

Now, I Want to know where is the "/etc/pve/firewall/cluster.fw" file?

I have 2x2 SATA (Softraid 1).
fdisk -l :

Partition 2 does not start on physical sector boundary.

Partition 3 does not start on physical sector boundary.

Partition 4 does not start on physical sector boundary.


Partition table entries are not in disk order.




(I Have read more than 100 pages, and tried them all. including https://forum.proxmox.com/threads/ovh-proxmox-root-password-recover-help-please.15394/)

So, At first i could access /dev/md2 (it was /dev/sdb2 and /dev/sda2 ?) BUT when i chroot ed and i went to /etc/pve , there was no /firewall directory. (when Proxmox was OK, in web interface, it was showing the storage as "ROOT" storage)

So, accidentally i stopped the /dev/md2 , but there is another /dev/md4 (/dev/sdb4 and /dev/sda4) that is 1.8TB (in Proxmox VE it was showing that my local storage). but i can't chroot it.
I tried :
root@rescue:~# mount /dev/md4 /mnt/
mount: unknown filesystem type 'LVM2_member' (SEE it didnt worked. So i used:)
root@rescue:~# mount /dev/pve/data /mnt/
and it worked, but showing "chroot failed to run command /bin/bash...."
But when i do cd /mnt/images , my VMs are there.

So, after i accidentaly removed /dev/md2 , I tried to make it again:
mdadm --create /dev/md2 --level=raid1 --raid-devices=2 /dev/sdb2 /dev/sda2 (I forgot the original command...) And it worked successfully, but when i tried to mount it:

mount: /dev/md2 is write-protected, mounting read-only
NTFS signature is missing.
Failed to mount '/dev/md2': Invalid argument
The device '/dev/md2' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?


Then, i tried changing the UUID on: /etc/mdadm/mdadm.conf (i think), but didnt worked either.
at last, i tried mkntfs /dev/md2 ........................ Then i could mount it. But no files.

--UPDATE--
also read https://forum.proxmox.com/threads/root-password-reset-proxmox-ve-1-9.10280/ .
there is no /dev/pve/root . only /dev/pve/data is available. no other.
--END OF UPDATE--

What to do!?!?!
Its so urgunt help please..
thanks

the /etc/pve/... directory is pmxcfs, see more details on:

Now Im on rescue mode, What I need to install and what i need to do to edit the firewall file!??

OR:
How should i get backup of "example" VM ID 105? its IMAGE is about 120GB !!! but used space is about 5-6 GB. i need the files used. like the 'backup' button in proxmox VE interface.
What should i install and what should i do to get backup of the files of VM ID 105?
 
you could set a systemd timer or cronjob from your rescue system that disables the firewall ("pve-firewall stop") after booting the regular system. then you can reboot, wait for the cron job/timer/.. to trigger, ssh in, fix the FW settings and then disable the timer/cron job again (and start the firewall ;))

In rescue mode you should actually be able to run `pmxcfs -l` (local mode) and then modify/delete files in `/etc/pve/firewall/`. (Alternatively you can use the sqlite3 cli tool to modify /var/lib/pve-cluster/config.db, but back up the file first.)
 
Ok thx for replies, i just used the cron job way and it worked .
but as i made some edits, some of files were corrupt. No problem i fixed them.
Thanks :-)
