Hi Community.
Below you'll find a short report on a problem that can be observed on Linux Systems with noexec option on /tmp partitions.
Problem Description:
VDP fails to complete a backup job with VMs containing mounted temp partitions (/tmp) with noexec option.
Reason:
VMware tools fail to execute any required VM scripts (pre or post quiesce guest OS scripts) due to no execution enviroment which finally leads to a halted VM .
Symptoms:
Kernel hangs. Linux proceesses report task timeout after 120 secs. VM becomes unstable. VM freezes and needs to be hard reseted
Affected Systems:
VDP 5.1.11.3 on ESXi 5.1
GuestOS: CentOS 6.4 + latest cPanel OR
GuestOS: Any linux with noexec parameter in mount options of temp directory
Possible solutions:
Shut down VMware tools and run VDP job manually OR
Shut down VM and run VDP job manually OR
Unmount tmp partition or disable noexec option in oder to let VMtools to be executed normally
(Explicitly for cPanel, disable during power-on secure tmp feature, chkconfig securetmp off).
Is it possible to change the default path of running of vmtools scripts in order to bypass this problem ?
Thank you all!
