Hi, I came across the following scenario while testing a dm-mirror created using dmsetup. One of the mirror halves was failed and the node was rebooted immediately afterwards so that when the node came up the failed disk was not only accessible but was also not configured. Now when I tried creating the mirror again using using the same target as before, it failed. In such a scenario, how do I create the dm mirror with just one half of the mirror available ? Is there a way to create a device-mapper device survive reboots, e.g. create a mirror once and then start and stop it, after node reboots. Is there a way to start the dm-mirror by using the " -u uuid " option instead of device names with dmsetup? What is the status of lvm mirroring, using "lvcreate -m" , how stable is it?
