Why shouldn't it be OK? I mean, you are using softraid, so I guess
you don't have a big server/network.
The problem I am having is that currently all partitions except
/holdingdisk are on the same raid5 (/backup, /, and /data). When
doing backups of /data and / to /backup the server is very slow and
bottle-necked. I think by switching the the above scheme will fix
the problem.
It ll still be a bottleneck if the new disks are softraid again. Try
thinking about a hardware raid controller (not one of the cheap
onboard raid which is handled by the CPU itself). But it is all a
thing of what you want to spend and if it's required. If you just have
a few GB to backup every night, it's surely no big deal. I have to
backup ~ 250 GB each night and 750 GB on complete level 0. For me it's
required to ensure that the backup finishes until next morning.
I have heard horror stories about hardware raid, and I like the openness
of Linux software raid. However if hardware raid is simply
significantly faster I will look into that.
Are there any companies/cards you (or anyone on this list) would
recommend regarding hardware raid controllers?
I know you recommended the 3Ware 9550SXU-8LP Sata Controller so I will
look at that one.
