file system corrupt in a virtual machine

Question

I have a virtual machine hosted by vmware esxi. It has been started for over 80 days. And about ten days ago, its file system got corrupted. Although I can use fsck to fix this file system, I am wondering what can be the root reason? It is just a virtual machine and there isn't any power off action.

BTW, that vm is not the only vmware on that host. There are several vms.

In this case, I suppose it could because of IO congestion. This machine want to flush virtual disk changes into hard disk, but there are a lot of other write actions. So its write action hangs in cache queue and get timeout later.

Is it possible?

update: add related information

VM's OS: Centos6.9

Disk attach type: SATA with default cache strategy

fsck: Doesn't pass the following check

Pass 1: Checking inodes, blocks, and sizes

Pass 5: Checking group summary information

As I cannot directly access to host machine, I cannot give more information about VMWare itself, sorry.

This is likely a problem with the underlying hardware of the VMware host server.

You have not posted any of the details of the hardware involved, the versions and build number of VMware, the OS distribution and version you're dealing with or anything else that would help find a root cause.

Is added information helpful? – Sraw Jan 31 '18 at 01:33
I would suggest contacting whoever is in control of the physical hardware. This is not something you can fix. – ewwhite Jan 31 '18 at 01:53
I think so, so I just looking for some possible reasons as they may help me to argue with them :) – Sraw Jan 31 '18 at 02:14
