Redhat & VM got hung while taking backup from SYmantec backup #79

Open unixsupport opened 8 years ago

unixsupport commented 8 years ago

I am running virtual machine OS RHEL7 and Application running is SAP.

Unexpectedly the VM got hung, after regular backup.

We are using snapshot backups through Symantec Netbackup.

We opened a case with Red hat and they replied that the vmtools is installed in /usr which is the same filesystem as /. IN RHEL 7 /usr is part / . other wise it gives error during installation.

Red hat said that root filesystem is freezed during the backup, as the vmware tools is installed in /usr/vmtoolsd, path , it is not able to replay the IO on the filesystem.

We are using open-vm-tools in this VM. Can somebody tell if there is a bug in the open-vm-tools?

unixsupport commented 8 years ago

The version of open-vm-tools is 9.4.0-6.el7.

Also is there is any i can disable the freezing action of openvm-tools?

Upgrade. See #16

@unixsupport please see https://github.com/vmware/open-vm-tools/issues/7#issuecomment-91704155 for steps to disable quiescing in the guest.

I suspect you have some NFS or Autofs mount point in the guest that is slow to respond and leading to this. Please open a support case with Red Hat to root cause it and Red Hat will contact VMware as needed.

I had opened a support case with Redhat they told that Vmtools freezes all filesystem during backup and when it tries to access the filesystem, it itself gets freezed.

They told to disbale vmtools or check with vmware.

I opened many cases with vmware but they are not able to find the cause of the issue.
