Re: [CentOS] Lost mdadm.conf

I've collected an howto somewhere from the 'net:

$ cat docs/sysadm/mdadm_recovery.txt

## define possible devices with arrays echo 'DEVICE /dev/hd[a-l]* /dev/sd[a-l]*' > mdadm.conf

## scan mdadm --examine --scan --config=mdadm.conf >> mdadm.conf

## review configuration, copy to /etc cp mdadm.conf /etc/

## create devices MAKEDEV md || { for ((i=0; i <= 31; i++)); do mknod /dev/md$i b 9 $i; done; }

## start arrays mdadm --assemble --scan

That's a fairly limited script and out of date, I've never used mknod...

Simply: # mdadm --detail --scan --verbose And look it over, then: # mdadm --detail --scan --verbose > /etc/mdadm.conf

And worry about mountpoints etc now...
