Objective

Rescue mode is a tool on your server that allows yous to kick into a temporary operating organization for the purpose of diagnosing and resolving bug.

Usual tasks the rescue mode is appropriate for include:

• Resetting your root password
• Diagnosing network issues
• Repairing a broken operating system
• Fixing a software firewall misconfiguration
• Testing disk performance
• Testing CPU and RAM

Backing up your information should exist the first footstep in rescue mode if you exercise not already have contempo backups bachelor.

This guide will evidence you lot how to actuate and use your server'southward rescue mode.

Requirements

• A dedicated server in your OVHcloud account
• Admission to the OVHcloud Control Panel

Instructions

Please note that if yous have prepare a default SSH cardinal in your command console for dedicated products, you volition non receive a root countersign when rebooting a server rescue mode. In this case, you must offset disable the cardinal earlier proceeding. To practice so, please consult this section of the relevant guide.

Y'all can activate rescue way only from your OVHcloud Command Console. Go to the Bare Metal Cloud section and so select the server on which to enable rescue mode from Dedicated Servers.

Look for "Boot" in the Full general information box and click on ..., then on Edit.

In the next folio, select Boot in rescue manner. If your server has a Linux-based Os, select rescue-customer from the menu. If your server runs on Windows, you can also choose "WinRescue" (run across the guide department beneath). Specify an alternative email accost below if you practise non want the login credentials sent to your customer business relationship'southward main address.

Click on Adjacent to proceed to the side by side step and on Ostend to validate the change.

Once the change is completed, click on ... next to "Status" in the box labelled Service status. Select Restart and the server will restart into rescue style.
This might take a few minutes; yous can bank check the status on the Tasks tab. An email will be sent which contains some data and the login password for the rescue way's "root" user.

Think to change the netboot back to Boot from the hd before restarting after finishing your rescue mode tasks.

Linux

Using rescue fashion (SSH)

If you are using an SSH key (too active in the OVHcloud Control Panel), you volition not be sent a password. Once the server is in rescue mode, you lot tin can connect directly via your SSH key.

Once your server has rebooted, you will receive an email with your rescue manner admission credentials. This email is also available in your OVHcloud Control Panel as soon as it is sent: Click on the name associated with your NIC handle (Customer ID) in the menu bar in the top right-mitt corner, so select Service emails.

You lot will and so demand to admission your server via the command line or an SSH tool, using the root countersign generated for the rescue manner.

For example:

            ssh root@your_server_IP root@your_server_password:          

Your SSH client will likely block the connection at first due to a mismatch of the ECDSA fingerprint. This is normal because the rescue way uses its ain temporary SSH server.

1 manner around this is commenting the fingerprint of your regular organisation by adding a # in front end of its line in the known_hosts file. Revert that alter before returning to normal boot.

For well-nigh changes y'all make to your server via SSH while in rescue way, you will need to mount a partition. This mode has its own temporary file organization, so whatsoever file system changes y'all make in rescue mode volition be lost one time y'all reboot the server in normal style.

Yous can mount partitions using the mountain command in SSH. Firstly, list your partitions in club to remember the proper name of the division you need to mount. You tin refer to the following code examples:

            rescue-client:~# fdisk -l  Deejay /dev/hda 40.0 GB,            40020664320            bytes            255            heads,            63            sectors/track,            4865            cylinders            Units            =            cylinders of            16065            *            512            =            8225280            bytes  Device Kick Start Stop Blocks Id Organisation /dev/hda1 *            1            1305            10482381            83            Linux /dev/hda2            1306            4800            28073587+            83            Linux /dev/hda3            4801            4865            522112+            82            Linux swap / Solaris  Disk /dev/sda            8254            MB,            8254390272            bytes            16            heads,            32            sectors/track,            31488            cylinders            Units            =            cylinders of            512            *            512            =            262144            bytes  Device Boot Start Finish Blocks Id Organization /dev/sda1            1            31488            8060912            c W95 FAT32            (LBA)          

Once you have establish the name of the partitioning you want to mount, use the control beneath:

            rescue-customer:~# mount /dev/hda1 /mnt/          

Your sectionalisation will now be mounted. You can and then carry out operations on the file system.

If your server uses a softRAID configuration, you will need to mountain your RAID book (normally /dev/mdX).

To exit rescue way, alter the kicking way back to Boot from the hard disk drive in the OVHcloud Control Panel and restart the server from the command line.

Mounting a datastore

You can mount a VMware datastore in a similar way as described in the previous segment. Firstly, install the necessary bundle:

            rescue-customer:~# apt-become update            &&            apt-get install vmfs-tools          

So listing your partitions in social club to retrieve the name of the datastore division:

            rescue-client:~# fdisk -l          

Now mount the partition with the following command, replacing sdbX with the value identified in the previous stride:

            rescue-customer:~# vmfs-fuse /dev/sdbX /mnt          

To go out rescue style, modify the boot way back to Boot from the hard disk in the OVHcloud Control Console and restart the server from the command line.

Windows

Using WinRescue tools

Once your server has rebooted, you will receive an e-mail with your rescue manner access credentials. This email is also available in your OVHcloud Control Panel equally shortly as information technology is sent: Click on the proper noun associated with your NIC handle (Customer ID) in the carte bar in the acme right-hand corner, and so select Service emails.

To utilize the Windows rescue fashion GUI, you lot will demand to download and install a VNC panel or use the IPMI module in the OVHcloud Control Panel.

The post-obit tools are already installed in this way:
