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.

To conclude, the recovery console has great features. Today, we saw our Support Techs describe its use for our customers.
