[OPEN-ILS-GENERAL] ***SPAM*** Re: Debian partition configuration question

[Yamil Suarez]

Ben,

Thanks for your suggestions. The system that I was testing with Debian  
is a Dell M600 blade and a M100e chassis combo. I believe the Dell  
hardware RAID is discribed as a "SAS 6/ir (H/W based) with RAID 0/1  
support." As far as I can tell, this Dell particular hardware set up  
does not support Debian. The 64 bit Debian installer did not run at  
all, and the 32 bit Debian seemed to install but had issues booting up  
and recognizing the RAID drives.

Could someone share with me a sampling of the server models for the  
systems they are running on Debian or other OSes?

Potentially, I might have to wait to install Evergreen on the Dell  
hardware I have with RedHat once Evergreen 2.0 is released. In the  
meantime, I will keep running and testing Evergreen 1.6.0 on an old PC.

Finally, any other suggestions or comments on using logical volume  
management (LVM) or separate partitions for "/home" , "/usr" , "/ 
var" , "/tmp"?

Thanks in advance,
Yamil
