2 harddrives?

Post by giloosh » Mon Oct 19, 2009 3:53 pm

How can zoneminder be configured to work with 2 harddrives? I tried enabling raid on my mobo and archlinux just recognized it as 2 seperate harddrives. Is there anyway around this?

You have two clean options to go use RAID/JBOD or LVM.

Here's Arch's documentation on these topics: http://wiki.archlinux.org/index.php/Ins ... AID_or_LVM

Even it you enable RAID on your motherboard, you still need to install and or configure your Linux system to use the hardisks in a RAID array. You'll still see sda* & sdb* devices in your dev folder when you have RAID correctly enabled. The RAID mapped device you'll want to mount in fstab will most likely be in the /dev/mapper folder.

LVM is another way to go. LVM is a linux software solution that maps multiple hard disks into a single volume. It doesn't have the performance boost RAID has (but if you're looking for a reall performance boost from RAID, you will be looking at buying an expensive RAID controller card) but you have a lot of flexibility. In LVM you can resize the merged volumes on the fly. If you get more harddisks, you can easily add them to you're merged volume.
