Warning Event: VFAT: 2600: Possible FAT corruption!

[fcturner]

Hi All,

On Monday I installed ESX Server 3i 3.5.0 build 103909 on a Dell PowerEdge 2950. I've loaded several VMs and stressed the system over the last couple of days. I just noticed two warnings in the event log that occurred yesterday afternoon and just now:

VFAT: 2600: Possible FAT corruption!: offset not found: 0x400, length 8704, seekOffset 0x400. File length: 9508, status: Limit excee (2:19:08:01.420 cpu6:833625)

VFAT: 2600: Possible FAT corruption!: offset not found: 0x400, length 8704, seekOffset 0x400. File length: 9506, status: Limit excee (1:23:08:01.512 cpu1:584272)

Any idea what these mean or how to diagnose them further? I searched KB and communities.

I have two raid volumes one raid 0 for boot/swap and one raid 5 for VMs. The datastore on volume 0 is not being used, just the raid 5.

Thanks,

I get the same error on a "whitebox", ASUS Workstation-Board with local storage for the OS and iSCSI (OpenFiler) for VMs.

Currently no guests are configured on that machine, so there no remarkable I/O.

Tested Build is 123629.

UPDATE

I just upgrade that machine to the latest patch 163429.

Also there was currently no VFAT-Event, the reboot after the update deleted the newly installed guests on it.

I had to add them manuelly from the SR.

Anyone else tested with Build 163429?

Seems like it is not fixed with the latest release.

I get the error: Warning Event: VFAT: 2583: Possible FAT corruption!: offset not found: 0x400, length 10240, seekOffset 0x400, File length 1114 (varies), status: Limit e (17:14:12:33:157 cpu1:5705998)

It's the "whitebox" ASUS Workstation with attached NFS. Before it was a VFAT: 2600, now it's a VFA:2583

Current build is 176894

Any news on that issue?

Are you using the latest version of ESXi on supported hardware?

[mmanda]

Thanks for your quick response.

No. I am still using ESXi 3.5. I will be Upgrading this in couple of weeks. But i am not sure if this has been resolved in ESXi 4.

I'm also seeing this issue on a ESX Server 3i, 3.5.0, 153875 on a Dell Power Edge 2850

I see the VFAT: 2583 randomly (10 times in the last month), but always at exactly 1 minute past the hour

At the top here it says there is a "Possible Answer" to this issue, but it doesn't seem to link you to that answer, I have scrolled through all 5 pages of post and I can't see any answer.

Is there one ?

Also when searching the discussions for VFAT: 2583 it doesn't even find this post !

Sorry Alec,

I could not find the answer for this yet. I still see this error sometimes, But i think its a minor one.

This weekend I am in the process of upgrading to ESXi 4. Lets see if that makes any difference.
