Hello,

I hope I'm doing this in the right section,
as the title says, I have a problem with a ESXI Server where a virtual machine is running.
The problem is that the server crashes from time to time in a ruffly 5-10tays rhythm the messages what I get in the event viewer are the following:

Message from localhost.localdomain: The redo
log of Server "NAME"-000004.vmdk is
corrupted. If the problem persists, discard the
redo log.
info
18/08/2016 4:27:51 PM
Server "NAME"
User

and 8 minutes after this comes:

Virtual machine on localhost.localdomain is
powered off
info
18/08/2016 4:35:45 PM
Server "NAME"
User

it is always the same process first i get this message that the file is corrupted and after a few minutes it will shut down
so I can start it again and everything works fine for another 5-10 days until the same thing happens again.

As you probably can imagine, I'm not a professional I understand a fair bit but I'm far away from being a "pro" some other guy did set the hole server up and I just try to keep it alive and working. So any help or suggestion will be helpful to me and let me know if you need more information to support me with my problem.

Cheers and thanks in advance
Christian

You have a snapshot which maybe corrupted, which needs to be handled correctly.

I can work with you on your snapshot issue.

Can you screenshot your VM folder and confirm you have snapshots present.

okay you have a VM possibly running on a snapshot.

and it's now possible that the VM may be corrupted. Can you check the VM properties and confirm, it is running on a snapshot disk. (See my EE Article)

What exactly does it mean "running on a snapshot disk" I'm not 100% sure what to look for.

And I just saw that I described it a bit wrong,  so not the ESXI server it self  is crashing it is just the virtual machine what is crashing.  

Sorry for the confusion.

Did you read my EE Article on snapshots ?

Edit the VM Settings, look at the virtual disk properties, and screenshot it and upload here.

okay, so this confirms what we need to know, the VM is running on a snapshot.

it is possible that the actually file -000004.vmdk is corrupted and there could be data loss, this is the danger of VMs running on snapshots when hosts fail.

so...can you attempt the following...

1. Take a new snapshot.
2. Wait 1 - 2 minutes
3. then select DELETE ALL...
4. Be Patient and WAIT...

snapshot merging (deleting) can take seconds, minutes, hours, days or weeks, depending on how large the snapshot, e.g. how many days the VM has been running on it, and the speed of datastore.

it may appear it's crashed, not doing anything, e.g. stuck at 90, 95, 100%, but it will complete, do not abort, or mess with the process.

BE Patient!

Okay sounds good so far,  I will start the process on Saturday,  just a little question, can the vm run and be used at the same time where I delete the snapshots?

Yes, if you can start the VM, but remember performance can be worse when merging a snapshot.

Okay yea I think that will be alright,  

Just a last question and then I won't disturb you any more for now ;)

should I do some kind of backup before I start merging?

If yes what method would you recommend?


I thank you very much for your support so far, you are one of a million and a very appreciate it.

Do you not currently have backups ?

the issue in it's current state, you may not be able to backup.

but you could always try something as simple as this in my EE Article

if you have a backup, then you are good to go.

if the snapshot is corrupted, you may have to restore you backup anyway.

Will my email signature work in Office 365?

You've built an email signature using raw HTML code in Office 365, but you can't review how it looks with Transport Rules. So you have to test it over and over again before it can be used. Isn't this a bit of a waste of your time? Wouldn't a WYSIWYG editor make it a lot easier?
