https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224496 Daniel Shafer <daniel@shafer.cc> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |daniel@shafer.cc --- Comment #10 from Daniel Shafer <daniel@shafer.cc> --- So I came across this same issue. It was causing my server to reboot several times a day due to kernel panics caused by this issue. It happens with both SAS9200 and 9300 controllers. I have 8 x 10TB Seagate Iron Wolf NAS drives. I wanted to mention that for me there was a resolution. I added an Intel Optane 900p 280GB drive and set that up for cache/l2arc and the problem entirely disappeared. My server ran for 20 days before I rebooted it last night to perform an upgrade. So, a workaround I believe would be is to add a cache drive to your ZFS pool. The Intel Optane 900p is a highly recommended cache drive for ZFS pools. -- You are receiving this mail because: You are the assignee for the bug.help
