| eliaswimmer | Hi, I just stumbled upon the account and password for manila generic share servers | 13:34 |
| eliaswimmer | and I have to say I was shocked! manila:manila | 13:34 |
| eliaswimmer | Where is this set and how can I change this to something secure? | 13:35 |
| tbarron | eliaswimmer: I didn't do it :) Seriously, that image as is is intended for testing, CI, not for production use. | 13:42 |
| tbarron | eliaswimmer: if you want to use it as your basis for production rather than, e.g. downloading a fresh ubuntu cloud image, you could use virt-customize to modify password, user, etc. | 13:43 |
| tbarron | eliaswimmer: https://libguestfs.org/virt-customize.1.html | 13:44 |
| tbarron | eliaswimmer: or build with disk image builder using this repo: https://github.com/openstack/manila-image-elements | 13:51 |

| *** sfernand has joined #openstack-manila | 14:02 | |
| eliaswimmer | tbarron: Oh thank you for the information, I think we should put that into the documentation too! (https://docs.openstack.org/manila/ussuri/install/post-install.html) | 14:03 |

| eliaswimmer | The other problem is, that one of my share servers run out of pcie lanes... and I have to switch driver to scsi. Can I cold migrate the server? | 14:06 |
| tbarron | eliaswimmer: if you have time to raise a launchpad bug for the doc issue that would be great | 14:07 |
| tbarron | eliaswimmer: I don't have experience with migrating share servers for the generic driver. In principle they are just nova instances ... | 14:08 |
| tbarron | maybe someone else here would know .... ^^^ or nova folks could speak to migration when switching machine types, pcie to scsi, etc. | 14:09 |
| eliaswimmer | oh, that should be possible, I am just not sure how manila will react | 14:17 |
| eliaswimmer | One solution would be to give a max share count per server instance | 14:18 |
| eliaswimmer | so that a new server spins up | 14:18 |
| eliaswimmer | right now it fails with an error that volume can't be attached | 14:18 |
| eliaswimmer | I had similar issues with cinder and kubernetes, where I have lots of volumes attached | 14:19 |
| tbarron | i guess you need to use virtio-scsi instead of virtio-blk for the nova instance and virtio-blk is the default to get past | 14:20 |
| tbarron | a 26 vol attachment limit? | 14:20 |
| eliaswimmer | What happens if I delete the nova instance? Will a new share server will be created? | 14:20 |
| eliaswimmer | What happens if I delete the nova instance? Will a new share server be created? | 14:20 |
| tbarron | eliaswimmer: the generic driver has no HA. | 14:24 |
| tbarron | eliaswimmer: once upon a time I thought about HA for service VMs: https://review.opendev.org/c/openstack/manila-specs/+/504987 | 14:25 |
| tbarron | eliaswimmer: as you see, it stalled ... | 14:25 |
| tbarron | eliaswimmer: it's considerable work and no one really has employer sponsorship to make the generic back end production worthy | 14:26 |
| eliaswimmer | just one more reason to use cephfs directly | 14:26 |
| eliaswimmer | here I have the issue with routing the network, a share network like with generic driver would be great to have | 14:26 |
| tbarron | eliaswimmer: yes, that's a downside of current cephfs back end (shared storage network) | 14:27 |
| tbarron | eliaswimmer: we want to use virtiofs to address that issue https://etherpad.opendev.org/p/nova-manila-virtio-fs-support-vptg-october-2020 | 14:28 |
| tbarron | eliaswimmer: but it will be a bit before that is ready. Most of the work will be in nova. | 14:29 |
| eliaswimmer | how are people routing it right now? a separate router, some individual routes, or as a separate network where nodes attach? | 14:29 |
| eliaswimmer | oh that sound like a good idea! | 14:29 |
| eliaswimmer | so clients don't have to bother about shares at all! | 14:30 |
| tbarron | eliaswimmer: downstream we have consumers boot up with 2 nics, eth0 on their regular private net and eth1 on the shared storage net. | 14:30 |
| tbarron | Then use security groups to protect themselves from other instances on that storage net. | 14:31 |
| tbarron | Not ideal, but it's what can be done for now. | 14:31 |
| eliaswimmer | tbarron: that's not possible with magnum ... | 14:31 |
| eliaswimmer | tbarron: magnum allows only one nic | 14:31 |
| tbarron | downstream we don't use magnum | 14:32 |
| tbarron | eliaswimmer: my point is not that the way we are doing it downstream is best, just | 14:32 |
| tbarron | stating facts about what people in the manila community are being paid to work on. | 14:33 |
| tbarron | Building a production quality generic driver would be great if someone had a way to fund the development. | 14:33 |
| tbarron | Similarly, magnum plus manila integration with ceph back end. CERN folks might have some solutions. | 14:34 |
| eliaswimmer | tbarron: I am working here for a large university, where we want to build a private cloud for scientific workloads, shares a really essential to us :) | 14:34 |
| *** lbragstad has joined #openstack-manila | 14:35 | |
| tbarron | eliaswimmer: That is awesome. I think Manila is a great fit for scientific and HPC workloads. | 14:37 |

| eliaswimmer | tbarron: My problem is well documented! https://docs.openstack.org/manila/ussuri/configuration/shared-file-systems/drivers/generic-driver.html#known-restrictions | 14:54 |
| tbarron | eliaswimmer: you may be able to build your service VM with virtio-scsi instead of virtio-blk to get around that limitation | 14:59 |
| tbarron | eliaswimmer: the only reference I find at this moment is in a ceph context, but it will I think give you the idea | 15:00 |
| tbarron | eliaswimmer: https://ceph.io/planet/more-recommendations-for-ceph-and-openstack/ | 15:00 |
| eliaswimmer | tbarron: yes that should fix it! Only question is how to migrate shares | 15:03 |
