Hi,
We're using storage replication to a DR site for our SUSE Linux servers. The data/log filesystems are running xfs. We have experienced data loss at the DR site when attempting to recover the FS's as the xfs log cleanup removes the open data/log files (things in lost & found but, it's like putting Humpty Dumpty together again).
Should we be using Direct IO for these FS's to avoid data in cache that hasn't made it to disk for replication causing the FS issues we're seeing at the DR site? Or, is there something else we need to employ to obtain recoverable data?
