Use case is : Two luns are mapped from storage array to linux host which are in same SAN fabric . we want to create a mirror on the linux host with these two luns and let host use that mirror lun . basic tests suggest that dm_mirror working fine . when we have any intermittent path issues with between host and san array , host i/o just freeze , never returns back even after the path is online. Is dm_mirror viable solution here ?. Can you point me any link which gives the limitations of dm_mirror ? . another alternate solutions you propose here ?. Thanks in advance . Thanks /Suresh |
