Re: [PLUG] NIC bonding

Hey Eric:

Let me guess you are a centos user too  ;-)

Acutally, I have considered using GFS (the redhat product). What do you think of it? Is it easy to manage? I acutally bought a HP product which is pretty fast. For the RAID, I am a little concerned. I am planning to implment RAID5 for 12 drives of 750GB. The problem is, if there is a bad drive it would take a very long time to place the RAID group as "stable". In other words, it would be in degraged mode eventhough we are in the process of replacing the drive and the array is rebuilding it self. Any thoughts on an optimal solution? I was thinking create 3 seperate RAID 5 volumes on the HW level (if thats possible with my HP product).

Anyway, thanks for your feedback. I was looking for a discussion like this.

Several things to consider:

1. Instead of NFS, you may consider iscsi with GFS.
2. Buy the most expensive drives you can afford.  You might hit the
drive's limitations before you hit the network's, especially if you're
using gigabit.  Also, put some thought into your RAID array or RAID
