The final command does not t= ake 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 o= n; 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 happen= ed only results in hanging those terminals as well. The only recovery method is a reboot. The sesutil process is hung in D+ sta= te 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 li= ghts 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 --=20 You are receiving this mail because: You are the assignee for the bug.=
