My Gentoo setup where the Vbox/VMWare executables are kept is a 3-disk RAID1. |
| 24 |
|
| 25 |
The VMs are kept on a 5-disk RAID6. It's this RAID6 that gets the |
| 26 |
workout when the VM gets busy. |

If you can the messages that you're concerned about then I can check |
| 29 |
for anything similar here. I'm currently running 3 VMs. |

Note that if it is a RAID issue that it might not be an mdraid problem |
| 32 |
but rather the actual disk drive not being up to the tasks it needs to |
| 33 |
perform. I have a bunch of 1TB WD Green drives on my bookshelf due to |
| 34 |
RAID problems. I replaced them with WD RAID Edition drives and haven't |
| 35 |
seen a problem since. |
