https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D223381 --- Comment #3 from Jim D. <randomnoise058@gmail.com> --- Update on situation (11/17/2017, 11:20pm CST) 1) created VirtualBox (VBox) SCSI controller and added VBox 3GB drive to it 2) modified FBSD-11.1 "fstab" to mount SCSI drive at boot (/SCSIhdd) 3) created shell script to run through a series of system commands on 3 iSC= SI drives, 1 zfs drive, 1 SCSI drive every 10 minutes; FBSD11 Zabbix client not running a) dd (15 times,count=3D1), fsck -Cn, zpool status b) tail /var/log/messages 4) no notable issues for several hours 5) started FBSD11 Zabbix cilent with Zabbix server active but Zabbix queries disabled 6) no notable issues 7) modified Zabbix configuration for FBSD11 client a) removed Zabbix FreeBSD template which included various file system che= cks b) left special locally developed template to perform HDD discovery, stat= us check, and other miscellaneous HDD information reporting 8) activated Zabbix server queries to FBSD11 client 9) script above continues to run without any notable issues 10) after some time, kernel WARNING messages related to iSCSI appeared kernel: WARNING: 192.168.1.19:3260 (iqn.2000-01.com.synology:ds216j.Target-7.c16e0895b7): underflow mismatch: target indicates 0, we calculated 4 11) stopped Zabbix server queries 12) modified special local Zabbix template to exclude extensive HDD status testing (ls, dd, mount, fsck, smartctl, ZFS pool status, iSCSI Target statu= s) 13) reconfigured Zabbix definition for FBSD11 client to use modified templa= te 14) re-started Zabbix server queries to FBSD11 client; above script still running 15) after 1.5 hours, no iSCSI related kernel WARNING messages have appeared Initial conclusion: something within the extensive HDD status testing is probably causing whatever to occur which results in the kernel WARNING messages. It may, or may not, be the iSCSI Target query using "iscsictl". More testing is required to further nail done the specific command(s) relat= ed to the iSCSI issue which as reported earlier which would eventually cause t= he FBSD11 client host to hang. --=20 You are receiving this mail because: You are the assignee for the bug.=
