Hi all, We are building a new system which is going to use ext3 FS. We would like to know more about the behavior of ext3 in the case of failure. But before I procede, I would like to share more information about our future system. * Our application always does an fsync on files * When symbolic links (more specifically fast symlink) are created, the host directory is also fsync'ed. * Our application is also going to front an EMC disk array configured using RAID5 or RAID6. * We will be using multipathing so that we can assume that no disk errors will be reported. In this context , we would like to know the following for recovery after a power outage: 1. When will an fsck have to be run (not counting the scheduled fsck every N-mounts)? 2. In the case of a crash, are the fsync-ed file contents and symbolic links safe no matter what?
