unJack

And mine as well, incredible, hadn't had backups for the last six weeks!

And again you were right. In the end I replaced one module after watching grep "[0-9]" /sys/devices/system/edac/mc/mc*/csrow*/ch*_ce_count closely, and that fixed it. Thanks Jorge!

Hi Guys, after setting up my new hardware with Unraid the last days, I'm pretty happy with everything! But today i discovered by accident that there are a lot of hardware errors reported in the syslog (btw, can those be reported via Notifications?). I'm concerned as I plan to store data on unRAID which must not be corrupted. Can somebody derive a possible root cause from those log messages? Is it a faulty CPU, MB or the ECC-RAM?
