I want to know what is the behavior of Yugabyte in case of single disk failures. Specifically:

1. What procedure should the sysadmin follow while dealing with a single disk failure? e.g. does stopping the TServer momentarily, changing the disk and restarting it automatically copy that disk’s tablets from other TServers?

2. Does a TServer automatically detect a disk failure and spread the data on that disk to other disks if the failed disk is not replaced within a stipulated time frame?

Thank you.
