| RoyK | openfire, nacc et al: bug #1059541 is a good example of how things aren't really cared for in the ubuntu server camp | 01:12 |

| kantlivelong | ahasenack: comparing the output of rpc.gssd between 16.04 and 18.04 looks very different | 15:49 |
| kantlivelong | it looks like 16.04 is looking for a machine entry with the FQDN where 18.04 uses the short name | 15:57 |
| kantlivelong | hostname.domainname.com$@DOMAIN.COM vs hostname$@DOMAIN.COM | 16:05 |
| kantlivelong | not sure if thats configurable | 16:06 |
| lotuspsychje | welcome Curtman | 16:13 |
| lotuspsychje | perhaps also mention the ubuntu server version to the channel | 16:13 |
| Curtman | I'm using open-iscsi to connect to a target, I would like to do 'rmmod g_mass_storage; modprobe g_mass_storage file=/dev/sda stall=0' each time the initiator connects to a particular target. Does anyone know how to make that happen? | 16:14 |
| Curtman | Ubuntu 18.04 | 16:14 |
| Curtman | Initially I tried adding 'modprobe g_mass_storage file=/dev/sda stall=0' to rc.local, but found that it does that before the initiator connects to the target. Does anyone have an idea how to make that happen after iscsid in systemd? My systemd-foo is not good. | 16:16 |
| lotuspsychje | idle here a bit Curtman, as we have different timezones volunteers might read a bit later when wakeup/back from away | 16:18 |
| Curtman | Yep, I'm not sure this is the best place to ask but I cant seem to find a better one. | 16:20 |
| lotuspsychje | Curtman: if you have ubuntu server your question fits right in here | 16:21 |
| Curtman | Well, the target is on a Ubuntu Server with the tgt package. The Initiator would be any debian based distro with open-iscsi. I'm hoping to make a rasperry pi zero (raspbian distro) connect to an iscsi target at boot, then use the g_mass_storage gadget to make the pi look like a usb mass storage device to whatever it is plugged in to. | 16:25 |
| Curtman | Everything works wonderfully if I ssh into the pi and modprobe the kernel module manually each boot. I'd like to find a way to automate that each time the target is connected. | 16:29 |
| Curtman | More googling leads me to believe my answer is udev. 'udevadm info -a -n sda' provides a bunch of information. Possibly I need to figure out how to create udev rules that insert and remove the module. | 17:37 |
| TJ- | Curtman: you need to remove/re-insert the module, or just insert it once at the correct time? | 18:03 |
| Curtman | Ideally remove it when the iscsi target disconnects and insert it when it connects. I think this is a good clue: https://www.suse.com/support/kb/doc/?id=3684654 "all iSCSI disks (identified by the vendor ID IET) will be ..." | 18:06 |
| TJ- | Curtman: you could add a udev.rules file, firing on ADD/REMOVE events, matching on the iSCSI device. e.g. ACTION=="add", SUBSYSTEM=="scsi", ENV{ID_VENDOR}=="IET",RUN+="/sbin/modprobe g_mass_storage stall=0 file=/dev/$kernel" and a similar ACTION=="remove" to do RUN+="/sbin/modprobe -r g_mass_storage" | 18:17 |
| Curtman | Thank you very much TJ- | 18:19 |
| Curtman | TJ-, I must be missing something, I've added exactly this to /etc/udev/rules.d/99-com.rules: ACTION=="add", SUBSYSTEM=="scsi", ENV{ID_VENDOR}=="IET", RUN+="/sbin/modprobe g_mass_storage stall=0 file=/dev/sda" | 19:06 |
| Curtman | It doesn't seem to be happening. | 19:06 |
| Curtman | I tried restarting udev, and even rebooting to be sure.. It should happen when I restart the open-iscsi service, /dev/sda disappears then reappears when I start it. | 19:07 |
| TJ- | Curtman: to begin with, I suggested using the udev variable to make it mroe modular, as in "...file=/dev/$kernel" | 19:08 |
| TJ- | Curtman: you need to ensure all the match entries do match (the == ) - I may not have it entirely correct, so you need to use "udevadm info ..." to check what the relevant keys/attributes are | 19:10 |
| Curtman | Yes, I think I've got it now.. ATTRS instead of ENV.. This seems to work: ACTION=="add", SUBSYSTEMS=="scsi", ATTRS{vendor}=="IET ", RUN+="/sbin/modprobe g_mass_storage stall=0 file=/dev/sda" | 19:15 |
| Curtman | Thanks very much for your helo | 19:16 |
| Curtman | help | 19:16 |
