Unable to mount drive after shelving

Support Requests
#1

Hi,

I have a volume drive attached to one of my instances in Cardiff, it is still attached when I check on Horizon, but when I try to mount it I have this error message:

mount: wrong fs type, bad option, bad superblock on /dev/vdb,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

If I check the syslog with dmesg | tail this is the message:
[1936664.449728] Buffer I/O error on device vdb, logical block 146800644
[1936664.452536] lost page write due to I/O error on vdb

How does it look?

Thanks,

Hi Andrea - this should all be fixed for you now.

The GVLs that you are running are very old, and their base image has a bug that we fixed in new GVLs a long time ago. The bug caused /dev/vdb to be automatically mounted at /mnt on boot because of a line in /etc/fstab. I’ve commented this out on your broken instance, rebooted and I’m able to mount the disk.

Newer GVLs have lots of accumulated fixes and updates, and are based on a modern version of Ubuntu. Please upgrade by terminating you current GVLs and starting new ones at your earliest convenience, thanks!

Thank you very much Matt, I will do.

Is there anything I should know before terminating my instances (i.e. how to do it safely for the data stored)?
When I terminate the instance I will lose things in the Home I imagine, but each drive mounted on it will be safe, am I right?
Do I have to unmount the drives before terminating the instances?
