Hello, I'm solving time/date synchronization of my small cluster, and I'm not sure which solution is the best. I'm using Debian on 1 master/8 diskless nodes with root over NFS. Filesystems for nodes are created via "diskless" package. I just figured out how to synchronize master from external source via ntp protocol. Now the problem is how to synchronize diskless nodes with master. Cluster is used fulltime for time-consuming computations and after several days/weeks/months of uptime the dates of nodes could quite differ.
I didn't have any problems with unsychronized dates but I'm not sure if such things like files created in future etc. couldn't be source of some nasty bugs. I'm not sure whether running ntp server on master and ntp synchronization on nodes is appropriate solution (maybe it is too heavy weight), other possibility is installing rdate and adding simple start-up and cron scripts. However I don't want to reinvent the wheel and I would like to hear how other people solve this problem. Pavel Jurus -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
