https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D226295 Bug ID: 226295 Summary: [iscsi] LUN modification error: LUN X is not managed by the block backend Product: Base System Version: 11.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: emz@norma.perm.ru Sometimes out of the vlue a "shadow LUN" appears, producing messages in logs similar to "LUN modification error: LUN X is not managed by the block backend".The lun mentioned is visible in the ctladm output abnd is stated t= o be of a type "block". ctladm remove on it is successful but usully doesn't res= olve the problem. This usually happens on aproduction system with properly configured targets. The workaround is to issue ctladm remove -b block -l X statements, then com= ment out all the targets that kernel complains about, issue killall -HUP ctld re= load until there will be no messages like that. Then uncomment all the targets b= ack, resume operations. last time 4 targets were affected. =3D=3D=3DCut=3D=3D=3D Mar 2 16:40:49 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:gamestop-reference,lun,0", CTL lun 11 Mar 2 16:40:49 san01 ctld[560]: LUN modification warning: error opening /dev/zvol/gamestop/worker02-ver11_662: 2 Mar 2 16:40:49 san01 ctld[560]: failed to reload configuration Mar 2 16:41:41 san01 ctld[560]: LUN modification warning: error opening /dev/zvol/gamestop/worker02-ver11_662: 2 Mar 2 16:49:24 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend Mar 2 16:49:24 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:gamestop-reference,lun,0", CTL lun 11 Mar 2 16:49:24 san01 ctld[560]: failed to reload configuration Mar 2 16:55:33 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend Mar 2 16:55:33 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:gamestop-reference,lun,0", CTL lun 11 Mar 2 16:55:33 san01 ctld[560]: failed to reload configuration Mar 2 16:57:34 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend Mar 2 16:57:34 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:gamestop-reference,lun,0", CTL lun 11 Mar 2 16:57:34 san01 ctld[560]: failed to reload configuration Mar 2 17:07:36 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend Mar 2 17:07:36 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:gamestop-reference,lun,0", CTL lun 11 Mar 2 17:07:36 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend Mar 2 17:07:36 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:games-worker01,lun,1", CTL lun 11 Mar 2 17:07:36 san01 ctld[560]: failed to reload configuration Mar 2 17:09:03 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend Mar 2 17:09:03 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:gamestop-reference,lun,0", CTL lun 11 Mar 2 17:09:03 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend Mar 2 17:09:03 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:games-worker01,lun,1", CTL lun 11 Mar 2 17:09:03 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend Mar 2 17:09:03 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:games-worker16,lun,1", CTL lun 11 Mar 2 17:09:04 san01 ctld[560]: failed to reload configuration Mar 2 17:09:41 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend Mar 2 17:09:41 san01 ctld[560]: failed to modify lun "iqn.2016-04.net.playkey.iscsi:gamestop-reference,lun,0", CTL lun 11 Mar 2 17:09:41 san01 ctld[560]: LUN modification error: LUN 11 is not mana= ged by the block backend =3D=3D=3DCut=3D=3D=3D --=20 You are receiving this mail because: You are the assignee for the bug.=
