https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235419 Michael La=C3=9F <bevan@bi-co.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bevan@bi-co.net --- Comment #1 from Michael La=C3=9F <bevan@bi-co.net> --- Did you have a look at what kind of disk activity there was? I experienced a very similar issue during my latest scrub: It was hanging b= ut there was still lots of IOPS on the disks. However, the throughput accordin= g to gstat was only roughly 1MB/s. This is actually more than the throughput sho= wn by "zpool scrub status" which was down in the KB/s region. I stopped the scrub, rebooted the machine and restarted scrub and it finish= ed without problems. I only experienced this after upgrading to 12.0-RELEASE. I thought it may be related to the new sequential scrub feature that fails to perform under cer= tain constraints (e.g., memory pressure) but that wasn't present in 11.2 as far = as I know. --=20 You are receiving this mail because: You are the assignee for the bug.=
