Ext4 partition damaged in CentOS 6 VMware

Post by luno16 » 2016/08/28 19:54:23

Gentlemen, I ask a help to be able to identify why Linux Centos partitions are damaged. I realized that this happens in VM's that have database such as MySQL (zimbra). It does not happen VM's Windows. I use the CentOS version 6.7 64-bit and vSphere ESXi 6.0.0, 2494585. Minhaversão and Zimbra 8.6.0 path 7
My host is an HP DL 360 Gen9 and the VMDK is the host of the disc itself. Below, let an example of the message:
EXT4-fs error (device dm-0): ext4_lookup: deleted inode referenced: 7078651
EXT4-fs error (device dm-0): ext4_lookup: deleted inode referenced: 7078651
EXT4-fs error (device dm-0): ext4_lookup: deleted inode referenced: 7078651
EXT4-fs error (device dm-0): ext4_lookup: deleted inode referenced: 7078651
EXT4-fs error (device dm-0): ext4_lookup: deleted inode referenced: 7078651
I would like some tips to find out why the partitions are getting damaged. It can be hardware problems? Vmware version? Or there is the correct way to install CentOS on VMware?
Thanks for help

Did your filesystem fill to full or did you mount filesystem to two systems simultaneously?

I noticed you have old version of system, what kernel do you use?

You should use newest version and kernel.

MGBE, thanks for the feedback. The kernel version is 2.6.32-220.el6.x86_64 #1 SMP Tue Dec 6 19:48:22 GMT 2011 x86_64 x86_64 x86_64 GNU/Linux

About mount the archive system for two simultaneous systems with Linux, it does not. What happens is that I have an HP storage, and shared for two HP host's too. To make a high availability.
This problem happens in the VM that is located in the storage and VM that is located in the HD host itself

You should have kernel kernel-2.6.32-279.el6 or above to resolve that system problem.

And make filesystem integrity check fsck.

If you have VM on share storage your hypervisor should manage it.

Mghe,

The kernel-2.6.32-279.el6 kernel corresponds to which version of CentOS? I am installed Zimbra 8.6 this VM.
 
  The complicated is that this happens in CentOS 6.7, 6.2 ....

Already I ran fsck on the partition and solved the problem, but the Zimbra database was damaged.

I did not understand when he wrote "If you have VM on share storage your hypervisor should manage it."

Thanks

So, you use CentOS version 6.7 with 2.6.32-220.el6.x86_64.

You should update your system to 6.8 version with newest version of kernel and run on it your VM to avoid this and others error and security issues.

Kernel kernel-2.6.32-279.el6 start from CentOS 6.3 version.

That "If you have VM on share storage your hypervisor should manage it." mean: if you use share volume to VM between many hypervisor, and something going wrong, not only CentOS should be damage.
