CloudSigma would like to inform you that we have performed a scheduled maintenance to one of our storage nodes. The actual change took 25 minutes in total.
All support activities were conducted under the direct supervision of CloudSigma’s operations staff.
IMPACT:
The storage node upgrade took 25 minutes in total. During the maintenance the following actions were applied:
(1) Prepared the upgrade by adding in new storage boxes
(2) Copied old storage boxes data to new storage boxes
(3) Paused the VMs with drives on old storage for 15 minutes
(4) Copied incremental old storage boxes data to new storage boxes while VMs were paused
(5) Brought the VMs back from pause
These actions prevent data corruption and minimized the downtime.
Please accept our apologies if this maintenance will cause any inconveniences to you and/or your daily operation.
While it is important for CloudSigma to perform maintenance such as this to ensure the quality of our services, we try to do everything possible to minimize any inconvenience to our customers. We appreciate your patience and welcome any feedback.

Scheduled
CloudSigma would like to inform you that due to the recent issues with the storage nodes, we will be performing an upgrade which will solve the stability issues seen recently. The upgrade was applied in our datacenter in Zurich 2.0 already and to one of the storage nodes in Las Vegas 2.0 and was successful. It includes hardware and software upgrades. Also we've been developing and testing different scenarios in order to minimize/prevent any service disruptions. After the tests we've found that the lowest risk and fastest execution to upgrade is:
(1) Prepare the upgrade by adding in new storage boxes
(2) Copy old storage boxes data to new storage boxes
(3) Pause the VMs with drives on old storage
(4) Copy incremental old storage boxes data to new storage boxes while VMs are paused
(5) Bring VMs back
This will prevent data corruption and will minimize the downtime, which will be a maximum of 10 minutes. from pause
All support activities will be conducted under the direct supervision of CloudSigma’s operations staff.
IMPACT:
During the maintenance some VMs will be paused for a maximum of 10 minutes but it is anticipated that it will solve the stability issues seen recently.
Next Update: 2013-10-16 , 09:30 UTC
Please accept our sincere apologies for the caused inconveniences.
Thank you for your understanding.
