I have a pool of drives, using MHDDFS, with a number of directories which are then shared using Samba by mounting the pooled directory, with bind, with the /var/lib/nethserver/ibay directories as mount points. This is working perfectly for what I need.
I have set the drive spin down time to 20 minutes using hdparm. But, it appears that there is a process that runs every 30 minutes that is waking all my drives from sleep 10 minutes later, without fail.
What process is this. I haven’t been able to find anything related to cron doing this.
