Wondering what is OnApp Recovery Console? Let us see its details.

With OnApp Recovery Console, we can help our clients to recover data.

As part of our Server Virtualization Technologies and Services, we assist our customers with several OnApp queries.

Today, let us discuss its Recovery Console.

OnApp Recovery Console

As we know, the recovery console has some great features for helping clients to recover their data.

When booting into recovery mode, we use:

User: root
Pass: <root/admin password shown in OnApp UI>

In order to use the recovery console, we select the virtual machine we wish to boot into the recovery mode.

Then we hit the reboot in recovery option in the VM’s overview.

However, the file system will not have the VMs disk mounted by default. This is because we boot into a recovery image.

To check the disks that the virtual machine has, we run:

[ root@onapp ~]# fdisk -l

Disk /dev/sda: 280 MB, 280252416 bytes
255 heads, 63 sectors/track, 34 cylinders
Units = cylinders of 16065 512 = 8225280 bytes

Disk /dev/sda doesn’t contain a valid partition table

Disk /dev/sdb1: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Units = cylinders of 16065 512 = 8225280 bytes

Disk /dev/sdb1 doesn’t contain a valid partition table

Suppose we need to run an FSCK on the disk. In that case, we can run a forced FSCK with the following:

[ root@onapp ~]# fsck -yf /dev/sdb1

After that, if we wish to roll back kernel updates or recover data, we can mount the file systems with:

mount /dev/xxxx /mnt

Then cd /mnt/ to access the filesystem.
