[Scheduled] Storage Nodes Upgrade LVS
CloudSigma would like to inform you that maintenance completed successfully. Due to the SAS driver issue with some storage nodes, we have performed an upgrade which have upgraded the final storage boxes that were still exposed to this stability issue. The upgrade involved the following steps: (1) Prepared the upgrade by adding in new storage boxes (pre-maintenance window) (2) Copied legacy storage boxes data to new storage boxes (pre-maintenance window) (3) Paused all VMs with drives on DSSD storage (start of maintenance) (4) Upgraded all storage nodes with the newest stable drivers (during maintenance window) (5) Bringed VMs back from pause (end of maintenance window) This prevents data corruption and minimized the downtime, which took about 13 minutes. All support activities were conducted under the direct supervision of CloudSigma’s operations staff. IMPACT: During the maintenance most VMs were paused for a maximum of 13 minutes, but it is anticipated that it will solve the stability issues seen recently. There is no data loss, corruption and/or any other service disruption. Please accept our sincere apologies for the caused inconveniences. If you notice any issues please do not hesitate to contact our support department via live chat and or email support@cloudsigma.com Thank you for your understanding.

Network issue in ZRH
CloudSigma would like to inform you that we experienced significant packet loss within our network in ZRH cloud location this afternoon. It seems that the port-channels flapped wich caused the network interruption. The issue is now resolved but during the above mentioned window you may have experienced difficulties accessing virtual machines within the ZRH cloud. All support activities were conducted under the direct supervision of CloudSigma’s operations staff. IMPACT: This event affected the network connection within our cloud in Zurich. As the network issue affected some of our compute and storage resources some running virtual machines may have lost network connectivity to their drives and became in read only state. In such case please power cycle your VM (simple restart will not do the job) and if the issue still persist, please do not hesitate to contact our support department over the live chat and or email support@cloudsigma.com. Please accept our sincere apologies for the caused inconvenience. We will update you as soon as we have more information on the root cause of the network issue. Next Update at: 2014-03-27, 15:30 UTC; 16:30 CET 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.

Unstable hosts in Zurich 2.0
CloudSigma would like to inform you that we have performed an unscheduled maintenance on a few of our hosts. It seems that the major cause of the issue is related to one of our storage nodes. All support activities were conducted under the direct supervision of CloudSigma’s operations staff. IMPACT: A few of our host servers became unresponsive. The virtual machines on those hosts were seen by customers as being in “unavailable status”. Please note that such VMs need to be manually restarted (power-cycled) through the web console. We strongly recommend you double check on your end to verify that everything is running as it should. Please accept our sincere apologies for the caused inconveniences. We will update you as soon as we have more information on the root cause of the host issue.

Storage Host Hardware Upgrade
CloudSigma would like to inform you that we are planning to replace one of our storage hosts, due to the instabilities you have experienced in the last week. We do not trust the hardware of the storage host in question and our policy is to replace any hardware we do not trust and retire such hardware entirely. The actual procedure is scheduled to take no longer than 15 minutes in total per drive, which we will perform during the one hour. The procedure consists of making a snapshot of the storage from the current host to the new host, integrity checking the snapshot, point VMs connection to attached drives to the new host. Several backup plans for the operation are in place including a physical swap of drives. The activities will be conducted under the direct supervision of CloudSigma’s IT operations- and development staff with additional support staff. During the maintenance for about 15 minutes some customer’s virtual machines will be stopped by our operations staff if the guest OS requires.
Jun 26
Emergency Storage Node Hardware Replacement
The storage node maintenance has been successfully completed. The new storage node is in place and all the data has been transferred. This should eliminate the last source of instability of storage in Zurich 2.0. The activities were conducted under the direct supervision of CloudSigma’s IT operations- and development staff with additional support staff. During the maintenance, VMs with drives on the affected storage node had to be power cycled. The downtime was 30 minutes in total. There is no expected data loss/corruption and/or any other service disruption. Any affected VMs should now be up and running, please log in to check that services running within your VMs have all recovered successfully. Please accept our sincere apologies for any inconvenience caused.
Jun 26
Emergency Storage Node Hardware Upgrade
During the migration preparation procedures for the storage node upgrade later today, the problematic storage node crashed. We have therefore expedited the planned hardware replacement now and all VMs are currently being recovered. The actual downtime should not take longer than 30 minutes in total. The activities are conducted under the direct supervision of CloudSigma’s IT operations- and development staff with additional support staff. There will be no data lost. All Virtual Machines were shut down through ACPI commands. When the machines come back up and running they will be on the new storage node. Please accept our sincere apologies for the disruption. Please note this crash renders the planned maintenance later today mute and it is therefore cancelled. We do not anticipate further maintenance disruption to your storage.
