Why all environment fall if one storage domain going down?
Hello all. Can any one tell me why all environment fall if we lost one domain storage? In my company we have many NFS storages and if just one going down, been rebooted, all host fail. What we realized, I do not know if it is true, is if one host can´t communicate with the storage it will be rebooted or if the use of memory is too high it will be rebooted too. Are those two impressions real? Best regards -- Atenciosamente, Kalil de A. Carvalho
Dear Kalil! The behavior is by design. The storage domains are defined inside a DataCenter (not Cluster object!) and they are mandatory for any host in the DataCenter. If a host has a problem with access to any storage domain that defined in the DataCenter, the host will change its status to 'NonOperational' (not rebooted!). If the host has the status 'NonOperational', all VM will be migrated to the other hosts (if VMs are HA and there is any host with free resources) or paused (if not).
