XFS filesystem on EC2 instance corrupts and shuts down

[Shrinath M]

Sorry to be asking in dev thread, but Amazon seems to be clueless in this
case :(
Can someone tell me where can we find the logs/output of xfs repair after
this runs? We just reboot the machine when we see this and the
/var/log/messages or dmesg seems to know nothing about what it repaired.
