I always recommend RAID 1 or 10 if possible. Make sure you put the MySQL database on a separate partition or separate drives if possible. Also, if you are doing recording you will want the /var/spool/asterisk/monitorDONE directory on a separate partition if you plan on keeping recordings on the machine for any length of time.

Be sure to use a RAM drive or tmpfs for recording within Asterisk.

please tell in detail about ram drive and also about swap partition
as my ram is 8 gb so how big i need swap.
and Is there any need of raid in dialer server where I have vicidial or its ok to leave dialer server without raid and make raid 10 on database server.

Moreover it is very easy to create raid 10 on fc 8 but little difficult on centos 5
I v tried raid 10 by webmin.
is there any other simple how to for raid 10 on centos 5

thanks in advance

tmpfs is enabled by default, and I believe there are instructions on tmpfs in the SCRATCH_INSTALL doc:

in the kernel, ensure that this File Systems option is enabled:
pseudo filesystems --->
<*> Virtual memory file system support
(this is usually checked anyway but mandatory for recording to RAM[tmpfs])

Then "vi /etc/fstab" # to include the following line for recording to RAM
tmpfs /var/spool/asterisk/monitor tmpfs rw 0 0

tmpfs will auto-size to available RAM.

As for SWAP, it would need to be at least 8GB to match your RAM.


As for setting up RAIDs, I only ever use Hardware RAID controllers.
