VMware VCB works by creating snapshots of VMs in quiescing state. If, while attempting to backup a VM, the following error shows up: .. ‘vcbMounter’ 3076465472 error] Error: Backup snapshot already exists. .. ‘vcbMounter’ 3076465472 error] An error occurred, cleaning up… There are probably some hanging snapshots of the VM that need to go. It [...]
Cannot Power xxxx. host on: Invalid virtual machine configuration. This error is a nice “catch all” and leads to configuration files corruption, improper snapshotting of VMs and other horror stories. My case is just one of “administration sloppiness”.. Indeed it’s worth to be mentioned to avoid some body’s else scratch their heads and think being [...]
It happened to me : transferring huge data files using TCP/IP based protocols is a pain when latency is noticeable. This is a problem that becomes more and more visible when you have computers or applications on different Clouds. Asperasoft is well known for their FASP product: a Layer 7 protocol for fast and reliable [...]
B-Virtual is a Belgian company living symbiotically with cloud solution provider A-Server and developing an IDA-based (Information Dispersal Algorithm) file system. A traditional disk subsystem obtains resiliency against data-loss by duplicating information (RAID 1 for example) or by adding check-sum stripes (for example: RAID 5). In typical Tier 3 or Tier 4 data-center applications, data [...]
Stunning how things go fast. As the VMware frenzy about vCloud Express is still hot (vCloud being substantially a long due API interface to perform capacity management), somewhat less of public domain happens: RightScale (my darling company) is supporting vCloud Express. It means we, common humans, could consolidate all types of Clouds we might want: [...]
Aspera is a company specialised in providing high speed, low-latency software solutions for data transfer. Their flagship product is FASP, a lightweight,resilient protocol implemented at Application Level that is a replacement technology for TCP-based transfers (the likes of FTP, HTTP). The nice thing is that it actually works! FASP is used mainly in the video [...]
Sometimes you just want to prove yourself it might work. Just that. While configuring two Solaris nodes to build a “sort of a cluster” (we called it “Moulinette”, the name should say all), I figured out how to avoid the unbearably slow Solaris 10 install: my imaginative solution is: create a ZFS mirrored pool on [...]
Great news. Kurt Claeys, the Cloud Computing expert and evangelizer at Ordina Belgium, founded AZUG: Azure User Group. Needless to say: their focus will be the Microsoft Azure platform and .NET Services. First public meeting is planned for September 2009, I will be there to see if I can help someways, count on it. Interested? [...]
