| ybaumy | hi guys. | 10:52 |
|---|---|---|
| ybaumy | jam: the new release fixed the juju status problems. you to let you know | 10:52 |
| ybaumy | question. can i deploy ceph-osd and nova-compute on on machine or doesnt it make sense | 10:53 |
| Dmitrii-Sh | ybaumy: sure it does, sure you can | 11:14 |
| ybaumy | Dmitrii-Sh: will high load affect storage performance not too much? | 11:15 |
| Dmitrii-Sh | ybaumy: depends | 11:15 |
| ybaumy | Dmitrii-Sh: thats what im worried about | 11:15 |
| Dmitrii-Sh | ybaumy: it is a sizing exercise in general | 11:15 |
| Dmitrii-Sh | ybaumy: if you have an all-flash array, you have to be careful | 11:16 |
| Dmitrii-Sh | ybaumy: as CPU load will increase due to a larger number of IOPS (or interrupts) | 11:16 |
| Dmitrii-Sh | ybaumy: + you need to process replication-related network interrupts which is also additional CPU load | 11:16 |
| ybaumy | Dmitrii-Sh: i probably have to test it in my lab first | 11:17 |
| Dmitrii-Sh | ybaumy: there is no general advice in terms of what's best. There are many things involved: the number of disks, their speed, CPU characteristics, NICs, jumbo frames, PCIe standard version (max speed on a bus), number of FileStore and osd threads | 11:18 |
| Dmitrii-Sh | ybaumy: and a workload of course | 11:18 |
| Dmitrii-Sh | if you stick a block-level cache there (e.g. bcache), it will affect CPU performance even more | 11:19 |
| ybaumy | Dmitrii-Sh: hmm there are alot of parameters to look for. | 11:19 |
| Dmitrii-Sh | ybaumy: yes, exactly. That's why it is worthwhile to know what is the desired result and have some fio-based test cases (https://github.com/axboe/fio) | 11:21 |
| Dmitrii-Sh | ybaumy: I haven't mentioned everything though, there are also things like instance CPU overcommit ratio and a number of instances on a compute node, RAID controller caches (if you use those), network switches' performance (whether they have a good backplane and can do line-rate switching on all interfaces at the same time), storage driver quality and other things | 11:24 |
| ybaumy | Dmitrii-Sh: you are alot of help for my thinking process. i will test this in test cloud and then i will see how everything plays together | 11:27 |
| Dmitrii-Sh | ybaumy: yw, it's a lot of parameters but it's good to try it out first and then optimize | 11:28 |
| ybaumy | Dmitrii-Sh: when i add-unit nova-compute it add a second ntp apperantly though port 123 is already used. can i just remove-unit ntp on the machine? | 11:48 |
| blahdeblah | ybaumy: There's a bug in some versions of ceph charms which installs NTP unconditionally | 11:49 |
| ybaumy | blahdeblah: it seemms that ceph-osd already has ntp installed | 11:49 |
| blahdeblah | https://bugs.launchpad.net/charms/+source/ceph/+bug/1690513 <-- that probably explains why you're seeing port 123 already used | 11:49 |

| ybaumy | ok thanks | 11:50 |
| Dmitrii-Sh | might be worth a backport to stable/17.02 | 11:52 |
| ybaumy | how do i juju deploy hacluster mysql-cluster --to machine ? | 14:25 |
| ybaumy | its not supported | 14:25 |
| ybaumy | is there any other way or how to proceed | 14:26 |
| ybaumy | got it | 14:58 |
| ybaumy | its a meta package | 14:58 |
| ybaumy | or something | 14:58 |
| ybaumy | how do i retry status when its blocked .. resolved doesnt work | 15:19 |
| ybaumy | would it be possible to display vip in status | 15:37 |
| ybaumy | how to resolv blocked status | 16:31 |
| ybaumy | or retry | 16:32 |
| ybaumy | or whatever | 16:32 |
| ybaumy | haproxy is up | 16:41 |
| ybaumy | but status says its blocked because haproxy is missing | 16:42 |
| ybaumy | i dont get it | 16:42 |
| ybaumy | https://bugs.launchpad.net/charms/+source/keystone/+bug/1599636 | 16:45 |

| ybaumy | jamespage: what is the workaround here | 16:46 |
| ybaumy | i did pause and resume | 16:49 |
| ybaumy | its resolved but why is this not a bug? | 16:49 |
| ybaumy | i had to pause/resume this on neutron-api hacluster and on every instance of neutron-openvswitch | 17:03 |
| ybaumy | in order to get rid of the blocked status | 17:04 |
| ybaumy | this seems to be a bug | 17:04 |
