After a powerfailure all files apart from the folders where completly gone. The server had never been rebooted after the files where put on the disk. All files where copied to the disk many days before the powerfailure and the total amount of files where >3000 and total of 200gb so its more than the ram might be able to cache.
When I ran fsck it didnt have any thing to complain about it said everything was ok. How come all the files where gone but not the folders?
This have hapened twice in one month now. Both time the powerfailure has hapened long after the files where copied to the disk. And both times all folders are still there but is empty.
The hardware is a HP DL380G5 with hardware raid5 and filetype used is UFS.
