I export a bunch of directories over NFS. One of those is the filesystem I record TV onto. At the moment, the recording machine is working on two separate channels, all streaming to the NFS filesystem.
My server just crashed. I rebooted it.
The recording machine is still quite happily going. I don't know if there's any lost data, but I doubt it. More news after those files get processed tonight...
(Sadly, another box that was also running a long-lasting job didn't survive the server reboot, but I challenge anyone running an SMB share to get a 50% success rate in this situation...)
