I see this on 2 out of 3 hosts. The one which does not exhibit the behavior only has 38 drives, while the ones which exhibit the bug have 80 and 100 drives. Reverting to 4.18.0-372.32.1.el8_6.x86_64 kernel works. |

Thanks for report! ZFS is 3rd party driver and looks like it needs to be updated for RHEL 8.7 kernel. Keep us updated on this please. |
