vCenter 6 Virtual Appliance and e2fsck and Superblock Errors

In our test lab we are using VMware  Essentials with the vCenter 6 appliance. When I boot the appliance it states I need to run fsck on my volume. I have followed the Vmware KB’s on this but not having any luck. I see a message stating that the /var file system cannot be found and believe this is on /dev/sda2. When I try to run e2fsck on this volume it states it has invalid Superblocks and does not repair / clean the volume?

Any thoughts or suggestions?

ASKER

The datastore it is on is healthy.. Alos when I do I control-D to reboot / exit it causes a kernel panic
I think for how long it takes to re-import a new vCenter 6 Virtual Appliance, I would start with a new fresh appliance, and see if the fault reappears.
I thought about that but was hoping to get my data off the old appliance...
All of the settings and and what not for our small lab environment.... The other real reason I want to fix this is so I can learn how to do it and get better at using Linux
When I type in    mount -n -o remount,rw     it displays back the menu items for the mount command and acts like it is the wrong syntax

When I type in mount -n -o remount,rw /dev/sda2 it stats that point swap does not exist...

I know of all people who can help me with this
I know most people would say just import the appliance again. But since this is on our I have an trying to "learn" more about linux at the same time.

when I run the df -h command I only see /dev/sda3 listed but it appears /dev/sda2 is the swap parition if I am ready everything correctly ...

I see the appliance has 7 disk attached and unsure which is used for /dev/sda2? how can this be fixed?
you can use

lsblk

Open in new window


to show the mappings to the disks.

lsscsi

Open in new window


this will show the disks, should be 11, VMDK3 should be SWAP
Thank you for sticking with me on this Hancock!!!!

I did try using the lsblk command and it did not display any results..

If the problem is with the swap partition can it be easily fixed?
nothing is easy if your Linux VM is broken.

does vCenter still function ?

does lsscsi work ?
When you boot the vCenter VM is does not boot all the way after the fsck message and system on the blue command screen so not I would say vCenter is not working but will confirm when I am back in the office...
That sounds like a very poorly vCenter Server appliance.

No backups ?
No backups since it was our test lab...

So for my own information..  In Linux if the swap partition is corrupt can it be easily fixed by pointing to a new swap location or is it not that simple especially with a vcenter applicance

When I run lsscsi it does not return any results
I ended up giving up and deploying a new VCA. It was do far gone but did learn some more stuff about Linux. Thanks for sticking with me on this
