https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=289627 Bug ID: 289627 Summary: Sesutil hangs after repeated usage Product: Base System Version: 14.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: ronald.w.taylor@gmail.com Created attachment 263825 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=263825&action=edit dmesg.boot file from affected box The following sequence causes sesutil to hang. The final command does not take effect (that is, the fault lights remain in the state they were just prior to the last command. riviera:/root# for i in 16 4 11 17 15 23 5 10 22 3 9; do sesutil fault da$i on; done riviera:/root# sesutil fault all off riviera:/root# for i in 6 0 8 14 20 1 7 13 12 2 19; do sesutil fault da$i on; done riviera:/root# sesutil fault all off (terminal hung at this point) Any further attempts to run sesutil in other ttys/ptys once this has happened only results in hanging those terminals as well. The only recovery method is a reboot. The sesutil process is hung in D+ state and connect be killed, and does not respond to Ctrl-C. USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 33940 0.0 0.0 13980 2580 1 D+ 08:54 0:00.00 sesutil fault all off Repeated invocations of `sesutil fault all on` and `sesutil fault all off` will also cause the hang. The reason for doing it in a for loop is I was trying to light the fault lights on each vdev in my zpool so I could verify the physical location of the corresponding drives. There are no obvious related messages in /var/log/messages or /var/log/daemon.log. The last messages before rebooting were 4 hours old at the time of the reboot. riviera:/root# uname -m -r -s -v -U FreeBSD 14.3-RELEASE-p2 FreeBSD 14.3-RELEASE-p2 GENERIC amd64 1403000 -- You are receiving this mail because: You are the assignee for the bug.home | help
