Spanned volume

Postby Spektro » Fri Nov 04, 2016 10:23 pm

Hello,
Would it be possible to implement a system where identically named partitions that located on different hard drives automatically formed a spanned volume, appearing as a single large volume. It would be really easy for the user to create a large volume, for example for backups.

I think someone wrote a RAID-0 driver or software solution for this, that's what you are after.
I'm not sure if there are also Amiga RAID-1+ options.

Here's some reading material; http://en.wikipedia.org/wiki/RAID

It would be possible, if spmeone wrote suitable software to identify and support such drives, but why would you bother? You can buy a RAID server for less money than an Amiga, it comes with full software and is accessible by other platforms as well.

I can't think of a single reason why I would want to tie up an expensive Amiga to do such a time-consuming job. Leave it to the x86 boards.
cheers

Ah, RAID 0 (striping) is a better version of JBOD (spanning). I thought all RAID types were about securing your data and not concatenating disks.

Salass00 has written a software RAID (swraid.device) but it's hard to set up. You have to create an xml configuration file and mount the RAID partition. If it were simpler to use, it would be perfect.

Well, I'm an Amiga user and not interested in the mainstream solutions :)
