The CORE db for freeswitch doesn't really matter - it's all state information (other than voicemail DB), so if it really all goes to hell, e.g. in a crash, then you're no worse off than opening a clean instance of freeswitch.

That'll leave you wide open to having a corrupted db, drbd too.

Personally i would use mysql cluster via odbc - all data on 2 nodes, which may or may not be on separate hardware to fs.

The other option for failover I was considering is the default sqlite - set up a job to rsync it to/from the slave constantly.
Perhaps even throw that into a ramdisk, if that makes a difference (the kernal may be caching it anyway).

Hi everyone,

i am trying to setup FreeSWITCH as a SBC in ha mode; for this purpose i have setup two FS boxes(identical) in HA mode using heartbeat, mysql as odbc backend and enabled track-calls in both sip profiles. Everything is working as expected i.e sip sessions successfully recovered during failover in both directions.

i am just curious and would like to know should i go for odbc or is it possible to avoid odbc and use drbd for /opt/switch/db directory to keep .db files in sync between two fs boxes. is it likely to work?

another question is related to performance when track-calls is enabled, we are supposed to handle ~300 sip concurrent calls around the clock in proxy_media mode, coming from our sip provider (on external profile) and forwarding to our call-center server (configured as internal sip gateway), we have plenty of good hardware (quad-core Xeon servers with 8Gigs ram), is it good to go :) or can raise alarms?


Thanks and best regards,
