Hi folks, If I understood the Linux-HA concept correctly, then it works because the services (NFS, Samba, EMail, Apache, etc.) share state information between the cluster hosts somehow. For NFS and Samba this state information is often stored in a file system on a shared block device, e.g. using drbd.
But does this concept work for the file system itself? AFAICS most Linux file systems keep state information in RAM. When the backup host takes over because the master died of something, does it really have consistent information on file system, service and application level? Sorry for asking. I am highly concerned because I saw 2 fatal file system failures within the last 7 days (xfs).
