However it seems that Jenkins fails to connect to many slaves :-/ I've rebooted: - slave46 - slave28 - slave26 - slave25 - slave24 - slave23 - slave21 These all seem to have come up correctly after clicking the 'Lauch slave agent' button on the slave's status page. Remember that anyone with a Jankins account can reboot VMs. This most often is sufficient to get them working again. Just go to https://build.gluster.org/job/reboot-vm/ , login and press some buttons. One slave is in a weird status, maybe one of the tests overwrote the ssh key?
