https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D246279 --- Comment #27 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> --- Thanks for taking an effort to test it again Peter. Without the patch you authored, the tests would end sooner with no panic and 40 instead of 140 dr= ives seen. That's a large setup and the solution is not ideal, but looks like a = step forward.=20 In the meantime I plied a bit with ciss(4) settings, and found out that set= ting hw.ciss.nop_message_heartbeat=3D"1" on which you complained in comment 25 b= reaks things also for me regardless of the application of the patch from D25155. = On the other hand, I am finding quite a useful new sysctl knob "hw.ciss.verbos= e" introduced by your patch for operations like drive replacement:=20 [7372] ciss0: *** Hot-plug drive removed, Port=3D1I Box=3D1 Bay=3D3 SN=3D= =20=20=20=20=20=20=20=20=20=20=20 PLXXXXX [7372] ciss0: *** Physical drive failure, Port=3D1I Box=3D1 Bay=3D3 [7372] ciss0: *** State change, logical drive 2, new state=3DFAILED [7372] ciss0: logical drive 2 (da2) changed status OK->failed, spare status= 0x0 [7372] da2 at ciss0 bus 0 scbus0 target 2 lun 0 [7372] (da2:ciss0:0:2:0): Periph destroyed [7444] ciss0: *** Hot-plug drive inserted, Port=3D1I Box=3D1 Bay=3D3 SN=3D= =20=20=20=20=20=20=20=20=20=20=20 PLXXXXX [7444] ciss0: *** Media exchanged detected, logical drive 2 [7444] ciss0: logical drive 2 () media exchanged, ready to go online [7444] ciss0: *** State change, logical drive 2, new state=3DOK [7444] ciss0: logical drive (b0t2): RAID 0, 139776MB online [7444] ciss0: logical drive 2 () changed status failed->OK, spare status 0x0 [7444] ciss0: logical drive (b0t2): RAID 0, 139776MB online [7444] da2 at ciss0 bus 0 scbus0 target 2 lun 0 Anyway, the patch proposed in review D25155 fixes a couple of things, was tested in JBOD and RAID mode and seems to not introduce any regression. --=20 You are receiving this mail because: You are on the CC list for the bug.=
