Thanks for the information Frank,

Is there anything that can be done to reduce the chance of this issue
happening again? and is there anything that can be done to recover the
files?

I've already installed a process to capture the ls -i output of the
file system every hour as our database don't change inodes so this
information would provide the source to recover the files from
lost+found.

Any other point ideas?

Regards

Peter
