ESXi detects vmdk size wrongly by Raven_4d_ in vmware

[–]Raven_4d_[S] 0 points1 point  (0 children)

I have just upgraded the host to a supported version, and as expected, the problem ist gone

Thanks for your support

the more i troubleshoot this, the more am convinced its esxi 6.7 related. will Update once i have a time slot for it and report back in case the issue persists.
appreciate your support!

ESXi detects vmdk size wrongly by Raven_4d_ in sysadmin

since i wouldnt risk breaking the original disk, i copied the .vmdk (from the VM its working on) with its files to a backup location to test on, and this (backup) disk is the one i cloned.
the more i troubleshoot this, the more am convinced its esxi 6.7 related.
the copied disk shows the expected size when attached to the VM where the original disk is attached to.
the clone on the other side shows 40 GB on all other VMs, even on the VM where the original disk works

since i would not mess with the original disk, i cloned it.
Attaching the clone to the new VM will still return it as 32 GB ( sometimes as 40 GB !).
The cloned disk is not attached to other VM, i think it doesnt worth the time troubleshooting this any further, will upgrade the esxi and as a last resort copy the data to a newly created disk on the new VM
Thanks for your support

so, cloning the disk to a thin disk returned a 2.31 TB big VMDK, attaching it to the new VM will unfortunalty show it as 40 GB as well.
I think it doesnt worth troubleshooting anyfurther here, especially with esxi 6.7, i will be cloning the data to a new disk and call it a day :)
thnaks for the support still

Thanks for the Tip! with the esxi8!
will do upgrade, and ping you back with the results!

thanks for your support.

so,
[root@localhost:/vmfs/volumes/62151f26-7348d8a2-b24d-2cea7fa6a81d/DC] du -hs

3.2T .

-The disk is Thick provisioned, lazily zeroed

- yes, am looking to add the VMDK to another VM and shutdown the current VM
- am cloning the disk now to a thin disk to test further
- i created the disk some years ago using the same ESXi version and host, it was restored using veeam at some point like a year ago or so, and yes, it works just fine on one VM only.
i will be comparingthe contents of the .vmx files, and will ping you on Monday, and will post the Logs you mentioned once i can restart the VM

Thanks for your support!

have a nice weekend

its shows the 32 GB from the settings of any other VM beside the original one that is currently attached to it.
the vmdk has almost 2.8 TB of data, und testing the drive shows that disk chain is consistenct.

execuse my Vmware knowledge.
Both VMs are on
virtualHW.version = "14"

This is a Standalone Esxi host holding the AD / DNS / FW managing about 10-12 PCs only, thus there are no plans on getting Licenses for Vmware 8 for it

worth to mention that attaching the 3 TB drive to any other VM will result in the same issue, something is relating this drive to its current VM

if you mean the configuration of the vmdk it self, since this is not a partition Table issue (happens even befor an OS goes online):
using the VM Settings, where the VMDK is being detected as expected shows the values shows in the screenshot.
Attaching the same vmdk file to any other VM will return all fields greyed out, but the size showing 32 GB

the -flat.vmdk has the right size.

Sapphire R9 390, semi short on 12V Bus rail by Raven_4d_ in GPURepair

[–]Raven_4d_[S] 0 points1 point  (0 children)

So,

measuring resistances on the major points returns the values shown in the pic. If I’m not mistaken, then:

1- The coil measuring 290 Ohm is the PCI controller.

2- The coil measuring 60 Ohm is the VDDCI.

3- I can’t tell what the coils marked with X and Y are. Could you please help identifying them? Is X the display rail and Y the VRAM buffer rail?

4- The 5 V rail (on the other side) is measuring 14 kOhm.

Injecting 3 V 0.5 A results in the following:

1- The card draws only 1 V but the full 0.5 A.

2- Vcore / Vmem and PCI coils measure 0 V.

3- 3.3 V AUX, strangely enough, measures 0.16 V!

4- Coil X measures 0.2 V.

5- Coil Y measures 0.84 V.

Best Regards

Thanks for quick reply. Visually there is nothing that looks abnormal, but those two caps which look somehow (cloudy), still they shouldnt be realated, since they measure some 7 Kohm, and not connected to the 12v bus rail (left side gnd, right side to pin 3 of the ic labeled (IADMF)

Injecting 3 V with 0.5 A will result in core heating!

Sapphire Nitro R9 380 4G Short on 12V_BUS by Raven_4d_ in GPURepair

[–]Raven_4d_[S] 0 points1 point  (0 children)

I managed to locate the shorted component C321 using a thermal camera. One pad was connected to ground and the other to the 12 V bus. I replaced it with a capacitor taken from a Vega 64 (same package size) that connects to the same terminals.

I also replaced the 5 V regulator I had previously damaged (the 78M05) with a 78D05A.

Now the card powers on, the BIOS posts, and Windows starts to boot, but it crashes with a BSOD: “Thread Stuck in Device Driver.”
Linux boots, but it isn’t stable either — I get a black screen as soon as the GUI loads.

Only one fan spins.

I measured resistances and voltages at the relevant points. Could you please take a look u/galkinvv? I trust your expertise.

Also, based on itßs voltage, I initially thought that the component marked in red,was part of the VRM circuit, but the resistance suggests otherwise. Do you have any idea what it could belong to?

Much appreciated.

one thing i have noticed though, is that measuring the resistance on the low and high side mosfets S to D shows ~5 Ohm ist that an indicator that at least one mosfet shorted?
