[Touch-packages] [Bug 1828617] Re: Hosts randomly 'losing' disks, breaking ceph-osd service enumeration
Yes, it is latest - the cluster is being re-deployed as part of Bootstack handover. Corey, The bug you point to is fixing the sequence of ceph/udev. Here however udev can't create any devices as they don't exist at the moment of udev run seems so - when the host boots and settles down - there is no PVs exist at all. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1828617 Title: Hosts randomly 'losing' disks, breaking ceph-osd service enumeration Status in systemd package in Ubuntu: Incomplete Bug description: Ubuntu 18.04.2 Ceph deployment.

Steve, This is MAAS who creates these udev rules. We requested this feature to be implemented in order to be able to use persistent names in further services configuration (using templating). We couldn't go with /dev/sdX names as they may change after the reboot, and can't use wwn names as they are unique per node and don't allow us to use templates with FCB. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1828617 Title: Hosts randomly 'losing' disks, breaking ceph-osd service enumeration Status in systemd package in Ubuntu: Incomplete Bug description: Ubuntu 18.04.2 Ceph deployment.
