I have OMV 6.9.15-2 (Shaitan) on Linux 6.1.21-v8+ (rpi4/ARM) with minio plugin installed and configured with just one s3 bucket used as backup store.
It's working as expected, I can see when backups are transferred there, I can use minio built in feature: monitoring->watch->start to see connections with their speed.
The thing that confused me was that I noticed HDD light indicator blinking all the time, this suggests some i/o
iotop points me to minio service:
it's 2-4 processes that constantly make about 100-400kB/s read.
Minio admin panel monitoring shows nothing at that time.
Power indicator shows me that drives are spinning all the time without any ability to go to any suspend. This draws constantly about 12W of energy instead of about 5W. If minio is disabled all i/o is gone.
Any ideas how can I make this service to not work that hard? Replication, encryption, quota, object locking - all off. It's just simple bucket for automated backups, about 85G now.
