| shutej | hi. i'm trying to determine whether block-device-added is a method, a hook, or a signal. | 16:13 |
|---|---|---|
| shutej | while reading the cookbook, i see: http://upstart.ubuntu.com/cookbook/#keybuk-events-are-like-signals | 16:13 |
| shutej | ^ this link is 404'ing | 16:14 |
| shutej | i'm on ec2 and i'm trying to respond to a volume being added or removed by mounting or unmounting. is this an appropriate job for upstart? | 16:15 |
| shutej | thus far i have this: http://pastebin.com/Y4pDMh9u | 16:15 |
| shutej | the block device has been added to the system (i can see it in /dev) but upstart isn't running the job | 16:20 |
| xnox | shutej: please see $ man 7 upstart-events | 16:58 |
| xnox | shutej: for the up to date events on your system. | 16:58 |
| xnox | shutej: i think you want events from the upstart-udev-bridge | 16:59 |
| xnox | shutej: man 8 upstart-udev-bridge and man 7 udev | 16:59 |
| shutej | HOLY WOWZERS! this man page is golden | 16:59 |
| xnox | shutej: so yeah, you should be able to see "block-device-added" event, which is generated by upstart-udev-bridge and has all the udev variables set, etc. | 17:00 |
| shutej | i'm installing the upstart job from cloudinit | 17:01 |
| shutej | while simultaneously asking ec2 to attach the volume AFTER it can SSH into the instance | 17:01 |
| shutej | i'm wondering if there's a race condition here | 17:01 |
| xnox | shutej: try "start on block-device-added" \n "exec env >> /tmp/block-events" | 17:01 |
| xnox | shutej: depends which ubuntu release you are running. | 17:01 |
| shutej | 12.04 | 17:01 |
| shutej | .3 | 17:02 |
| shutej | :-) | 17:02 |
| xnox | shutej: ssh test is not good enough, wait for cloud-init to finish (it happens after one can ssh into the system) | 17:02 |
| shutej | how would i test for that remotely? | 17:02 |
| xnox | shutej: and you want "initctl reload-configuration" to pick up the job (potentially, depends on how instances are available) | 17:02 |
| xnox | shutej: well, try to ssh and check for existance of the magic file (it's something like boot-completed, or finished, or sum such under somewhere /var/*/cloud-init/*) | 17:03 |
| shutej | so basically i should ssh in from my control script, issue some command that waits for cloud-init to finish | 17:03 |
| shutej | and then initctl reload-configuration manually (cloudinit doesn't do that)? | 17:04 |
| shutej | and THEN attach a volume | 17:04 |
| xnox | yeap. | 17:04 |
| xnox | (cloudinit does do reload-configuration automatically, in certain releases, from saucy and up) | 17:04 |
| xnox | so in next lts you will have it. | 17:05 |
| shutej | thanks for this, it's been about the most helpful 10 minutes of this day. | 17:07 |
| shutej | off to read. | 17:07 |
| internetpanda | I am running 6.4 and wanted help with an upstart script to run a search daemon for mediawiki. here is my upstart script which doesn't work: http://pastie.org/8389924 | 18:20 |
| internetpanda | I believe it may have something to do with jave | 18:20 |
| internetpanda | java* if anyone can please help it'd be greatly appreciated | 18:20 |
| shutej | move respawn outside script | 18:32 |
| shutej | for that matter | 18:32 |
| shutej | remove script and end script | 18:32 |
| shutej | exec will be sufficient | 18:32 |
| shutej | stop on ... | 18:33 |
| shutej | respawn | 18:33 |
| shutej | exec /usr... | 18:33 |
