Hello,
Sorry for my ignorance, I was hoping someone could clarify for me the
proper procedure for rebuilding a softraid mirror. The man page/faq says:
Rebuilding a mirror
When a drive failure happens, you will replace the failed drive,
create the RAID and other disklabel partitions, then rebuild the
mirror. Assuming your RAID volume is sd2 and you are replacing the
failed device with sd1m, the following commands should work:
#*bioctl -R /dev/sd1m sd2*
#*reboot*
These steps can be performed in either single user mode
<https://www.openbsd.org/faq/faq8.html#LostPW> or from the install
kernel <https://www.openbsd.org/faq/faq4.html#bsd.rd>.
Does this mean that a RAID rebuild can *only* be performed from single
user mode or install kernel, or is it possible to rebuild an array while
the system is in full operation?
To phrase my question a different way:
Is it possible to hot swap drives and rebuild arrays on the fly, or will
this bork my system?
Thanks,
Jordan Geoghegan
