<div class="gmail_quote">Hi,<br><br>I want to run Dm-raid1 or dm-mirror in degraded mode. <br><br>So say I have 2 Disks and I create a mirror device over that.<br>Create EXT4 over the new device, mounted it and started a huge number of IO using dd on that device.<br>
Now while the IO are going on, I failed the 'Default' Mirror in the mirror set.<br><br>Then ideally the IO operation should not break. All the IO should go to other mirror.<br>But it is not happening. Either my dd command hangs till the default device comes back or it returns an IO error <br>
and breaks the IO operations on disk.<br><br>Is this is known behavior ? <br>Or<br>I am missing something in configuration ?<br><br>I am using Kernel 2.6.32. <br>Mirror target's version is 1.12.0 <br><br>Please help !<br>
<br>Thanks,<br>Gaurav <br>
