Hello again.
Seems things are working as it should, for now at least.
I have ran scrub 3 times over the last 36 hours, and no errors have been shown.
Im not 100% sure what solved it, might be a combo, but will list my latest changes that seem to have solved it:
- Fan blowing air directly on both HBA’s (Thought i had good enough airflow, but maybe not…)
- Moved HDD’s around, making sure i only have one Seagate drive on each backplane
- Added one more SATA-power from PSU to the backplanes (Had only one that split to all 6 backplanes, powering all the drives 18HDD+6SSD, now its split between to cables from PSU.)
- Had to do a reinstall of OS as somehow boot-partition was lost from BIOS/UEFI after i change a setting, and rollback didnt work… Not sure why boot-device got lost, but whatever…
Im guessing heat might be the problem on HBA, will se if i will do a test without the fan and see if same errors occure again.
But for now, it all seems to work great.
Thanks for all the help/replies
