Hello. I use 2 disks in mirror with root partition on softraid. Say they are sd0a and sd1a and SR is sd2. For example sd0 fails. I shutdown system, replace failed drive, boot from good one, copy layout, rebuild array, all disks online and system is up and running. Then sd1 fails. I shutdown system, replace sd1, power on and...
Using drive 0, partition 3. No O/S _ Reading manuals, faqs and mailing lists led me to the following: I reproduce the issue and after replacement first failed drive run # installboot -v sd2 After that I can boot successfully from both drives. Unfortunately I can not find this solution (is it a solution?) neither in Disk Setup FAQ nor in lists. I edited it for myself and here is diff for faq14.html. ########################## $ diff -ur faq14.html.orig faq14.html --- faq14.html.orig Sun Jan 31 20:12:36 2021 +++ faq14.html Sun Jan 31 21:45:55 2021 @@ -643,6 +643,23 @@ <a href="faq8.html#LostPW">single user mode</a> or from the <a href="faq4.html#bsd.rd">install kernel</a>. +<p> +Also you advised to issue command: + +<pre class="cmdbox"> +# <b>installboot -v sd2</b> +</pre> + +Otherwise in case if your second drive will fail this may lead you to + +<pre class="cmdbox"> +Using drive 0, partition 3. +No O/S +</pre> + +message after reboot + + <h3 id="softraidFDE">Full Disk Encryption</h3> Much like RAID, full disk encryption in OpenBSD is handled by the ##########################
