Is there any way to set up a software RAID..? Please help.
Hi, I think I may be asking the impossible but I wanted to double check before I try swapping my hardware etc as I've spent a lot of wasted time messing about trying to set it all up. Is there a wa...
Caveat: I've only ordered my ReadNas today so know nothin about its own software, but doing what you want independently using standard Linux facilities ought to be quite easy - if you want to go to the trouble. I magine the biggest difficulty might be 'hiding' your USB disks from the RN software so it doesn't try to use them itself. OTOH this might be easy - I just don't know the proprietary software yet.
Anyway to provide one big vol from two in the usb rack you have two ways (probably more).
1) As sugested before use software raid. Simply look aty the devices and see your two usb devces, then use one of the unix raid too;ls (I like mdadm) to create a raid volume from this. Now you see 3 devices, the two originals plus the raid device of their combined size (if you choose raid 0). Then simply use this new device like you would any other i.e. craete a file system on it and then export it or publish to windows with samba or do whatever you like with it. It may even be possible to use this combined device with the RN software but I wouldn't know about that.
2) Use LVM. Just create a volume group and assign both physical devices to it. Then create a single logical volume using the whole space in the volume group i.e. both drives. Then use that new logical volume the same way you would with the above raid volume or any other system volume i.e. create file system and export etc.
The second option is probably the easiest and most flexible. Note that both are only really suitable if you can both get the RN software from interfering with them and you are going to leave them permanently connected, they are not hotplug solutions.
