Assuming by "other PCs" you mean you're sharing files to other machines using CIFS (samba) or NFS, I wouldn't worry too much. Most distro's usually do a shutdown of services before they stop the local filesystems and raid array so any 'loss' of data is usually caused by a user who hasn't saved their files before the server went offline. Once the clients have been disconnected, the shutdown should handle stopping the raid array just fine. -- Drew "Nothing in life is to be feared.
