The role played by distributed file system replication (DFSR) is crucial to keeping data properly synchronized when it’s spread across several different servers.
However, when issues occur, this can lead to disruption and even the possibility of data loss. So troubleshooting DFSR snafus is a priority for any admin.
There are a few common conundrums you’ll need to overcome, so here’s a look at what these are and how you can counteract them.
Conflicts caused by antivirus software
There are lots of great antivirus solutions out there, and so long as they are properly configured and kept up to date, they will protect your mission-critical IT resources from outside exploitation.
Problems can arise if the antivirus package you choose interferes with the DFSR process because it wrongly detects this as being symptomatic of a malware infection and thus prevents data from being synced between servers.
The solution is simple; all good antivirus software will let you set exclusions for certain programs and processes so that they can run unhindered. Adding exclusions for DFSR should address any interference. If you’re not certain that antivirus is to blame, disabling it temporarily will let you check this in a jiffy.
Hold-ups with scheduling
It’s not unusual for backlogs of unsynchronized data to build up over time, with certain files remaining in limbo, with the system stating that they are scheduled for replication without this ever actually occurring.
There are a few ways to go about clearing DFSR backlog issues, and running a diagnostic report using DFS Management should give you an accurate overview of the state of play and potentially pinpoint where the conflict exists.
It could be as straightforward as deleting and rebuilding the replication group from the ground up. This equivalent of the old ‘turn it off and on again’ trick still works for exorcizing ghosts in the machine.
Complications with bandwidth bottlenecks
Often the DFSR issues you’re faced with come down to improper configuration of key settings, and one of the biggest bugbears relates to bandwidth allocation.
If the amount of usage assigned to scheduled replication tasks is artificially limited, then obviously this will result in delays that could confound you. You can deal with this from within the Schedule sub-menu of the DFS Management tool, from where you can disable any bandwidth throttling, or even implement it if the replication process is monopolizing too much of your network capacity, for example.
Mishaps relating to out of date software & drivers
When your infrastructure involves multiple servers and a varied combination of software and hardware devices, staying on top of updates is a must if you want to sidestep DFSR issues and all sorts of other dilemmas.
It’s not just a case of rolling out software updates for things like the aforementioned antivirus solutions, but also implementing drivers for individual components of your setup when fresh versions are made available by the original manufacturer.
Eliminating this as a variable from your troubleshooting is sensible, and if you’re on top of your general maintenance duties then it should ideally be something you’ve already done anyway.
The bottom line
You want your DFSR to occur seamlessly every time, but this is something that you will need to work to achieve. And the benefits of being proactive in optimizing performance and avoiding the likelihood of conflicts and delays arising far outweigh any of the time that you’ll need to dedicate to these preventative measures.
Keeping data consistently synchronized, clean and uncorrupted will serve your organization well and preserve continuity.
