I'm trying to replace a (still working) disks with a bigger one on mdadm 3.1.4 but "--replace" is not reconized: # mdadm /dev/md0 --add /dev/sdd1 --replace /dev/sda1 --with /dev/sdd1 mdadm: unrecognized option '--replace' Usage: mdadm --help for help which version is needed for "--replace" ? Any workaround ? Currently, i've solved with: mdadm /dev/md0 --fail /dev/sda1 mdadm /dev/md0 --add /dev/sdd1 mdadm /dev/md0 --remove /dev/sda1 but is not the same as i'll loose part of redundancy (it's a 3-way mirror) Probably, would be better to add the new disks, grow to 4-way mirror and when done, remove the old disk and then shrink to a 3-way mirror. Any way to do this automatically, like with --replace, that should remove the failed disk only when replacement is done successfully? -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
