I have multiple DCE VM's running simultaneously on separate clusters. Had them for 5 years or more without much trouble. Recently a cluster has been failing and we have lost a DCE server for a period of time (obviously all the monitoring is lost or not collected for this period too). The first time it happened I asked the monitoring team to implement a simple ping check to see if the server is still operating. I was happy at this point. But barely had I washed the sand out of my toes from holiday and I come back to work learning that the cluster has failed again and the ping test failed because the VM was still responding to a ping even though the service had crashed. My question then is : How can I get an alert to tell me a DCE VM is no longer online or working? (There is something ironic about my monitoring service not being monitored itself). Here is the guff from the virtualisation team: Many operating systems will still respond to a ping, even if the service has crashed. This is a linux feature where is makes the file system read-only, but keep the network stack up to allow you to connect to it. This is where a service check is required. Something that test for a running service, or a port that’s only open when the service is running. A port scan of the o/s might be able to pick up what is open, and that could be requested as a check. The other alternative is to ask the vendor if there is something that can alert from within the o/s to advise there has been an issue. Thanks in advance

Just a note that this situation is still happening. My warnings are now that I am at 558Gb which is way over our 300Gb limit and I only believe a normal backup of the system is about 160Gb. We have 4 duplicated "synchronised" folders for our single DCE VM now - each with a different timestamp, some are nested. It appears then that these additional folders are not merely tracking changes to our system but more probably creating entire backups again.

Greg, The type of connections for this required event will be inputting patching, mostly in rack patching, between servers and switches already installed in the system. We do have new locations being added but these will mostly be already installed in the system (location/room/rack/equipment) before the patching stages, in other words a large install of all the nested equipment and its patching cannot be run in one upload. I was aware of the upload sheet method that is not configured by default but also recognise that this system has limitations of requiring the deletion and re-adding of all the connectivity (e.g. upstream UPS etc.). I understand the caveats of this system and frankly it does not fit our needs as I need the remote teams in other regions to update their systems, simply, at their leisure. Using a csv or similar upload function for patching would help accelerate the data upload. As the locations involved have small numbers of racks to update I think it is easier for the local engineers to update the patching using the manual tools. If the numbers of racks were say, in to 3 figures, we might need to re-assess though. I think we can close this ticket but I remain interested in developments in this area, if as you suggested, there might be future functionality in ITA using REST API.

Thanks Cory. This issue happens every 9-12 months or so. Every time I go to the storage team and ask them to delete the duplicated folders that appear unnecessary (doing it myself remotely is too slow). They do this repeatedly for a week, then the problem appears to go away again for another 9-12 months. The storage team insist the problems (flagged by their own automated capacity warning systems) are not created by their routines or actions and I believe this to be true. I understand what you mean by the backups updating new changes (like Windows File History function). I am not sure that the solution lies with our local teams but to this end I will forward all comments from this thread to the teams helping.

Hello, When we first installed DCO 5 years ago there was no facility to update cabling information using csv or xls files after the initial established system installation. In other words to add another datacentres connectivity information to the established system would mean manually inputting all the connectivity. We have continued in this vein since, but I thought I would ask again if this situation has changed (perhaps with the migration to ITA?) We have more locations coming online and would like to know if there will be an opportunity to upload a csv or similar before doing it all manually. Thanks

No I checked and the system is set to Synchronized but does not have the compress option ticked. I don't understand why the synchronized folders are sometimes nested within previous synchronized folders too. This increases the duplication which impacts my capacity limits?

Sometimes I receive alerts from our storage system that I am over my capacity allowance. This appears to be due to DCE creating duplicated backups on the system. The folder created is "synchronized_"hostname"_"datestamp"_7.6.0 Do you know of any reason multiple folders would be created?

The User has told me this morning he has moved platforms and is using Win64 now.

I have read the installation instruction documents but do not find any mention of the questions asked below by our virtualisation team. They are: Does the Appliance tolerate vMotion? Does the VM require any non-standard settings as recommended by the vendor? – E1000/VMXNet3 virtual NICs, Paravirtual SCSI controller, RDM Disks etc.

The user is reluctant to downgrade his Java which I think is higher at 1.7 or something. The error appears as attached. I think in this case we will have to pursue the upgrade and hope that once we migrate to ITA this user can continue to use the desktop client or be satisfied with the larger feature suite in the web client. He is a read/write user.
