Re: md autostart?
the way i licked this is i took the md entry out of the fstab and after the boot script finishes i have a shell script that performs the filesystem check on the md then mounts it. this works like a charm in our shop.

After doing that, using "mdcreate" to make an mdtab entry, and adding a line to my fstab, everything started "magically" working. I have been using a raid0 partition quite heavily for a few months, and it works very well. Later, Dale -- + finger for pgp public key -+ | Dale E.

Re: md autostart?
MD setup is easier than it looks. When you used mdcreate to make /dev/md0 it wrote a file called /etc/mdtab. You do not have to modify /etc/init.d/boot since it already has a call to "mdadd -ar" if it and /etc/mdtab exist. In other words, if you are running a recent copy of the sysvinit code and you used mdcreate to make /dev/md0, you probably are already getting it enabled at boot time. Here's what I did to get mine working: # mdcreate raid0 /dev/md0 /dev/sdb2 /dev/sdc2 /dev/sdd2 /dev/sde # mdadd -ar # e2fsck -fyv /dev/md0 # mkdir /raid # echo '/dev/md0 /raid ext2 defaults 0 1' >> /etc/fstab # mount /raid # df "cool, it works!" OK, so I hammed it up but you get the idea.

Hi there, I just put the md package to use, and I have some semi-important questions... 1) Do I need to do anything to ensure that my /dev/md0 has been started if I expect to use it in /etc/fstab? If so, where do I put that? My kernel has md compiled in (not a module). 2) Can I also assume that it'll get unmounted cleanly and properly? Thanks for your help, Pete -- Peter J.

I made it by puting a script into /etc/rc.boot, but I agree mdutils should supply it.
