I’m looking for some guidance on adding RAID1 to a system after installation. Basically, I used SNG7-PBX-64bit-1805-1 to install to a system with two 80GB Western Digital Blue drives that looked fairly identical, but were made about a year apart. Unfortunately, FreePBX did not consider them identical (they formatted to slightly different sizes) and therefore did not auto-configure them for RAID.
So, I’ve now got it installed on one drive (the ever-so-slightly smaller one, so there should be room to clone everything on the other drive). Is there a guide on how to do this after the fact? I searched, but all I could find was this:
…which is pretty clearly out of date.
I can find generic Linux guides for doing this, but they all assume that you just have normal /dev/sdX partitions to deal with. With FreePBX, we have /dev/mapper/SangomaVG-root – so I wasn’t sure if I could follow one of those guides without messing something up.
If someone could provide some instructions and/or update the Wiki for the current Stable release, that would be great. Thank you!
