This article describes the troubleshooting steps in case of a Virtual Appliance installation failure
AB - Installation
This article explains to install Acronis software on Linux systems without installing packages required for compiling SnapAPI module on every machine. Instead, it's possible to install Acronis agent on a test machine and distribute precompiled module over your systems.
On the source machine:
1. Build SnapAPI modules:
This article informs about supported Microsoft Exchange versions and provide steps to troubleshoot issue with installation failing with error “MS Exchange server is not installed or has an unsupported version".
Follow these steps to troubleshoot issues with “MS Exchange server is not installed or has an unsupported version" errors during installation of Acronis Agent for MS Exchange.
Collect information for investigation of Linux operating system lockups.
Operating system may hang under specific circumstances. To identify the exact cause, it is necessary to analyze Acronis System Report and a kernel dump.
Always make sure you have the latest build of the product (if it's possible).
Because Acronis products work with the storage system of an operating system on a very low level, there is a small risk that different conflicts on this level can lead to an operating system crash during backup or other operations. Please follow the instructions below to troubleshoot these issues, depending on what operating system is being used..
1) You are trying to install, update, uninstall, register or unregister Agent for Mac.
2) Agent registration on Management Server fails with the error message:
Could not resolve host: localhost; nodename nor servname provided, or not known
Under specific circumstances, the software may crash. It is very important to report a crash instead of trying to workaround it. Normal workflow for a crash problem is the following:
Product may hang under specific circumstances.
There are 2 types of hanging:
- Actual hanging. That is a state similar to a crash. That means that software halts and is doing nothing inside.
- Infinite loop. This means that on the outside the software looks hanging but inside it is doing some actions over and over again.
Usually when a software hangs its process uses either 100% of CPU (especially when it is infinite loop) or does not use CPU and does not change RAM usage at all (Actual hanging). Still it is difficult to make sure if the software hangs or not. The above means that usually 1 dump is not enough because if that is Infinite Loop – the developers will see that software is working and there is no problem inside. So in order to troubleshoot application lockups you need about 5 dumps collected one after another. A Process Monitor Log will also be useful especially if it actually turns out to be an Infinite Loop.
Please note that an application lockup does not necessarily mean the software is completely unresponsive. A process can hang (e.g. service_process.exe hangs and a backup is stuck), but you can still browse vaults, create new plans etc.
Define the hanging process using Windows Task Manager. In some cases multiple processes are involved in an operation. In this case the hang of 1 process can be caused by some operations in another process. In this case you need to collect memory dumps of all processes involved in the operation. E.g. if a backup to Acronis Storage Node hangs, you need to collect a dump of service_process of the agent as well as StorageServer.exe process on ASN machine.
