When I add devices to mirror in device mapper and activate I have: # dmsetup table isw_dgdccjfdbi_test: 0 20971779 mirror core 2 16384 nosync 2 8:16 0 8:32 0 1 handle_errors # dmsetup status isw_dgdccjfdbi_test: 0 20971779 mirror 2 8:16 8:32 1281/1281 1 AA 1 core After removing one of disks I can still work on the volume and device mapper take care of writes to disk that is left and change its status. # dmsetup table isw_dgdccjfdbi_test: 0 20971779 mirror core 2 16384 nosync 2 8:16 0 8:32 0 1 handle_errors # dmsetup status isw_dgdccjfdbi_test: 0 20971779 mirror 2 8:16 8:32 1281/1281 1 DA 1 core However after rebooting that system I cannot create device mapper table with missing device. # dmsetup create isw_dgdccjfdbi_test 0 20971779 mirror core 2 16384 nosync 2 8:16 0 8:32 0 1 handle_errors device-mapper: reload ioctl failed: No such device or address Is it possible to create table with missing device and tell device mapper to set missing device status to "D"?
