Good day, Someone gives me several limitations of DRBD For MySQL? Here is the list,
1. Idle resource – secondary host sits idle, wasted investment 2. Failover is not instant, nor transparent -"Cold standby" failover 3. Recovery requires time to start / recover database 4. Recovery process can fail – requires reload 5. Requires database journal capability -MySQL MyISAM does not work 6. Operation not continuous: planned downtime required -Active-passive does not cover DB maintenance -Anything that requires mounted disk 7. Does not address scaling or performance 8. OS Limitations – Some only run on Linux May someone elaborate or disprove those points? Thanks. -- Regards, Mohd Irwan Jamaluddin Web: http://www.irwan.name/ Blog: http://blog.irwan.name/
