Hi,

I had a set of servers crash yesterday and they have asterisk installed on them one serving as a back bone and the other as a standby both are running cent os
One was crashed showing kernel panic and both one's mysql server crashed without giving error, so far i managed to recover most tables in to the database

I checked /var/log/messages as well as mysql logs.but didnt found anything in it.

Request every one to please help me with what we should actually have done in this scenario and how to safeguard against these in the future.

Both these servers were running with a total of 15 people logged in at the time for calls and mysql database is continuously accessed for the calling data such as phone number & addresses. both are dual core machines with 2 gigs of memory each

Thank you

MySQL has a feature called database replication which you can use to replicate your data on another hardware/machine. This way you wont rely totally on backups or your current machine. You can reduce the MTTR.
