--- Comment #56 from Wayne Willcox <wwillc...@gmail.com> --- Ok so it looks like I solved this for my system. I did it by reducing the command tags. The default was 255 and I started by just cutting that in half. I kept dividing by 2 until I got to 25. At 50 I only had the time outs every few days. At 25 I have not had an error in over a week. I could possibly increase from 25 but I won't bother. Performance seems to be fine and the errors are stopped. You can do this with the camcontrol tags command camcontrol tags [dev_id][generic args] [-N tags] [-q] [-v] Here are the steps. camcontrol devlist <IBM-XIV ST2000NM0001 A2 BC42> at scbus0 target 8 lun 0 (pass0,da0) <IBM-XIV ST2000NM0001 A2 BC42> at scbus0 target 9 lun 0 (pass1,da1) <IBM-XIV ST2000NM0001 A2 BC42> at scbus0 target 10 lun 0 (pass2,da2) <IBM-XIV ST2000NM0001 A2 BC42> at scbus0 target 11 lun 0 (pass3,da3) <IBM-XIV ST2000NM0001 A2 BC42> at scbus0 target 12 lun 0 (pass4,da4) <IBM-XIV ST2000NM0001 A2 BC42> at scbus0 target 13 lun 0 (pass5,da5) camcontrol tags da5 (pass5:mps0:0:13:0): device openings: 25 Originally mine was at 255. This can be done on a live system and doesn't require closing the disk and reopening it to take effect. I just changed all 15 hdisks. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
