I am looking for recommendations on how I should setup partitions on this new email server (Kerio) under RHEL 4.5. Here is the hardware config of the server:
Dell PowerEdge QuadCore, 8Gb RAM, Perc6 Raid
Array 1 (/dev/sda): 2 x 146Gb as Raid1 for the OS and Kerio software
Array 2 (/dev/sdb): 6 x 300Gb as Raid10 for all the Kerio mail files for all users
This server is only going to be used as a mail server.
We did a test install and the automatic partitionning would create the partitions as follows on the Raid1 disk:
/boot - 100Mb on /dev/sda1 (out of the LVM)
(root)/ - 134Gb on VolGroup00/LogVol00
swap - 2048Mb on VolGroup00/LogVol01
For the Raid10 array:
/kerio - 880Gb on VolGroup01/LogVol00
The default partitionning was not offering to create any other partition (/usr, /home, /var, /tmp). Just one large partition for / (because of the very large amount of unused space that this drive will have ???)
So my questions are:
1) Should we use LVM or go with regular partitions ?
2) Would you suggest different partitions and sizes other than the ones proposed by the default RH install ?
3) swap partition: default install would create 1 swap of 2Gb. Section 4.16.4 of the RH manual says it should be: 2 x physical RAM for up to 2 GB of physical RAM, then 1 x physical RAM for any amount above 2 Gb, which should equal to 10 Gb in this case ( 2x2Gb + 6Gb = 10Gb). And if the total swap size required is > 2Gb, to split it in multiple swap files of 2Gb. Is this right ?
