Colleagues, one of my servers start to expose unexpected delays possibly related to disk subsystems. It's Supemicro with mfi, ZFS on set of RAID0 (yes, I know we've missed the right controller, but this is out of question at least for the current time) Now kernel log is filled with messages like mfi0: 60006 (585001405s/0x0002/info) - Unexpected sense: PD 0e(e0x08/s5) Path 500304800021bf31, CDB: 8f 00 00 00 00 00 14 77 5c 1e 00 00 10 00 00 00, Sense: 3/11/00 every few seconds I tried to find the place in the source which produce these lines but failed :( Hard reboot, including full power off, was tried, but did not help. Any hints to diagnose this further? Ah, and this is stable/10 from Nov 2017 please keep me CC:d as I'm not subscribed to -scsi@ Thanks! -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
