Getting File <unspecified filename> was not found

What happened was I tried to expand the C: drive on the target server NET17. So I shutdown the server, expanded it by 100GB (Server is running 2008 R2 Enterprise) and when I go to turn it back on I get this error message.

File <unspecified filename> was not found.  I have attached a screen shot of the error.

We are running vmware esxi 4.1 on all vmware servers.
The version of vSphere client is 4.1.0 build 258902
The vmware vcenter server is 4.1.0 258902

The Server Sit's on a compellent SAN. Nothing has changed on the SAN. I have tried restarting the vmware management service on our vSphere server, I've removed the server from inventory and re-added it into the inventory and still nothing.

I even took a shot in the dark and went into the data store, did a manual download of the server, uploaded to the Raid's on one of our actual vmware servers and still nothing.

We currently do not have snapshots enabled for this VM which is NET17.   I did check in the settings and everything is pointed to the correct location on the SAN for the VM and nothing has changed on the SAN either.

Any help would be great.

Thanks,

have you checked the datastore virtual machine folder for snapshots?

We currently do backups with a software called Appasure.

There are no snapshot's in the datastore. Here is a log file from the datastore for the server.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

please screenshot datastore folder, this error is so common when a disk is expanded with a snapshot attached. It should not allow you to expand a disk with snapshot but can do, because this is a bug.

the resultant error is what you have observed, only way to check folder.

unless VM disk is locked by another process.

something is rather odd with the name of the vmdk because normally you would see the name in the datastore browser as e.g. net17.vmdk

not -flat ?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
i would check the datastore on console or ssh

to check you have

NET17.vmdk this is a small file descriptor

and

NET17-flat.vmdk this is the actual data disk

also someone been renaming files, because the foldername NET17_3 is often the machine name and virtual disk names and config files?

because in your screenshot you will notice VMware vSphere does NOT recognise the net17-flat.vmdk because there is no disk icon associated with it.

its a blank white icon, it should have a disk icon associated with it.

Hey Guys,

All your suggestions lead to this
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1002511


My boss arrived and when I showed him the issue and the datastore he knew what was missing and took me to the above KB from vmware (he's been doing this a lot longer then i have :P ).
We did have to recreate the vmdk file.

I do have another question then. what happened to the file? All I did was try to expand the  Hard Disk 1 (which is the C: drive) by 50GB.

All I did was shutdown the server, right click edit settings, go to HD 1, expand HD to 150, click ok and then try to power it back on.

Glad you got it working, and recreated the missing file.

Strange things happen, did not write the file back.

Even though haccocka didn't provide the exact solution, His comments were right on track and we would've ended up going that route any ways.
I give the solutions he gave an A because of effort and the fact we were on the right track.

my next post would have been this is how you create your missing vmdk file!

you have the advantage you have the system to hand, I rely on you as my eyes!

If I had remote access, it would have been fixed in 30 seconds!

Good Luck.

Lol I believe you Hanccoka and I thank you for your assistance which is why i gave you the full 500   :)



Also as a side question do you have your VCP? if so how did you obtain it? You seem pretty knowledgeable in this and I've been trying to get my VCP for a while (getting work to pay for it isn't easy).

The best advice I can give you is use the products, experience the products, know and read the documentations. Build your own lab, if you do not have the time at work. Get yourself on a Certified Course, needed before they will grant you the VCP.

try the practice exams

http://www.simonlong.co.uk/blog/vcp5-practice-exams/

try the mock exam

http://mylearn.vmware.com/mgrSurvey/assess.cfm?item=24908&user=0&refer=0&p=0&ui=www_cert

as for me, I'm VCP free, 14 years of VMware Experience, I mentor and train Engineers for their VCPs!

Maybe one day soon......! I just have a little issue of the Course Fees! (before they grant me my VCP!).

Good Luck with your VCP5, and you've always got EE to ask Questions.
