MITIGATING SIESMIC EVENTS VIA HIGHLY AVAILABLE VOLUMES

According to one embodiment, a method, computer system, and computer program product for mitigating vibration damage to a distributed storage system is provided. The present invention may include classifying at least two of the drives comprising the distributed storage system as vulnerable and not vulnerable, respectively, and responsive to detecting that a site associated with the distributed storage system is at risk of a vibration event, turning off the vulnerable drives at the site; creating a thin mitigation layer comprising thin-provisioned volumes associated with standard volumes comprising the vulnerable drives; routing read IO addressed to the standard volumes instead to associated partner volumes; routing write IO addressed to the standard volumes instead to the thin-provisioned volumes; and responsive to determining that the site is no longer at risk of a vibration event, turning on the vulnerable drives and copying states from the thin-provisioned volumes to the standard volumes.
