Hi
As per notes in Slurm documentation (e.g. https://slurm.schedmd.com/configurator.easy.html): State Preservation Define the location of a directory where the slurmctld daemon saves its state. This should be a fully qualified pathname which can be read and written to by the Slurm user on both the control machine and backup controller (if configured). The location of a directory where slurmd saves state should also be defined. This must be a unique directory on each compute server (local disk). The use of a highly reliable file system (e.g. RAID) is recommended. StateSaveLocation: Slurmctld state save directory SlurmdSpoolDir: Slurmd state save directory In our experience, this works just fine with NFS mounted state directories. Hope that helps ~~ A ________________________________ From: jupiter <[email protected]> Sent: 29 July 2016 11:52:06 To: slurm-dev Subject: [slurm-dev] Synchronise between ControlMachine and BackupController Hi, Does slurm have the mechanism to synchronise scheduler jobs and states between the ControlMachine and BackupController? If not and if it is admin's responsibility to take care about it, there could be following two options: 1. Set up a single node for mysql and slurmdb, point the variables of StateSaveLocation and SlurmdSpoolDir to the remote single db node. The question is, how can the values in StateSaveLocation and SlurmdSpoolDir be set up to a remote location? Or it is not possible? 2. Set the variables of StateSaveLocation and SlurmdSpoolDir to a share location which mount to both StateSaveLocation and SlurmdSpoolDir. What is your recommendation? Thank you.
