Zettastor | I don't write the unit test codes completely and only do the integration test. I want to submit driver codes ASAP and submit unit tests later. is that okay? | 09:36 |
tosky | you can't ignore test cases; that's part of the basic theory of testing | 09:45 |

tosky | it's possible to ignore that, but IMHO (please note that I'm just a random contributor here for cinder, but I do work on testing) is usually a call for (later) troubles | 09:47 |

*** enriquetaso has quit IRC | 18:22 | |
qqmber | because I'm trying to getting up a server (elasticsearch) that has 230G in data that has to be loaded when I load the app.. but after a couple of seconds, the volume where the 230G are, is remounted as read only. | 18:23 |

*** enriquetaso has joined #openstack-cinder | 18:28 | |
smcginnis | I have not seen that myself, but I know in the past I've had iscsi or kvm get into weird states when there's connectivity issues and start treating a volume as read only. | 18:30 |
smcginnis | I wouldn't really expect that when it's all on the same host, but maybe some other kind of failure (IO timeout or something like that) causing it. | 18:30 |

qqmber | I'm possitive the disk doesn't have physical problems | 18:44 |
smcginnis | Could be timeouts. Is the system under heavy IO load when this happens? | 18:44 |

smcginnis | Ah, OK. | 18:45 |
qqmber | smcginnis: no.. now is not very loaded... | 18:45 |
jrubenst | linux file system ext4 will set a volume to readonly if it can't write to the volume. | 18:46 |
qqmber | jrubenst: do you have any clue where should I looking for? | 18:46 |
qqmber | jrubenst: can't write due a timeout maybe? | 18:47 |
qqmber | and the timeout due it is "traveling" thru iscsi (even it is in the same host)? | 18:47 |
jrubenst | if you know which file system you are using you can try fsck which can run file check or repair | 18:47 |
*** itlinux has quit IRC | 18:48 | |
qqmber | let's see... in the instance, the volume it has ext4 | 18:48 |
qqmber | I'll do a fsck to the volume (unmounted) | 18:49 |
jrubenst | That will work | 18:49 |
jrubenst | If iscsi is bouncing the connection you should see messages in the kernel log for the session coming and going | 18:50 |
qqmber | $ sudo fsck /dev/vdb1 <-- it says "clean" after less than a second... | 18:50 |

jbernard | smcginnis: not explicitly | 18:52 |

smcginnis | cat /proc/sys/crypto/fips_enabled | 18:54 |
smcginnis | sysctl crypto.fips_enabled | 18:54 |
jbernard | 0 | 18:54 |
smcginnis | I'm wondering about FIPS because SHA1 is not an allowed hashing algorithm. | 18:54 |
smcginnis | Hmm, I guess that shoots down that idea. | 18:54 |
jbernard | even more interesting, it only happens when a ceph backend is present in "enabled_backends" | 18:55 |
jbernard | if that variable contains only lvm, the error goes away | 18:55 |

jungleboyj | mnaser: Ping | 19:51 |
mnaser | hi | 19:51 |
jungleboyj | Hey. Totally random question ... | 19:51 |
jungleboyj | There is a group in Lenovo that is running a pretty sizable OpenStack cloud. | 19:51 |
jungleboyj | They are looking at upgrading to the next OpenStack release but had some issues the last time they tried this. | 19:51 |
jungleboyj | They were asking me if I knew of any best practices, etc. for doing upgrade in a prod. environment. | 19:52 |
jungleboyj | Was guessing you might have a little experience there. | 19:52 |
mnaser | hard to answer, i think the gotcha's are a little more release oriented for example | 19:52 |
mnaser | from => to which releases? | 19:52 |
jungleboyj | They are currently on Rocky I believe. Previously they did Pike to Rocky so I think they are preparing for Rocky to Train after it is available. | 19:53 |
jungleboyj | Their questions were around, is it safe to update one node of the environment at a time and then update the control system. I think, with microversioning, that should be safe. | 19:55 |
jungleboyj | mnaser: Yeah, it will be Rocky to Train. Which, since train isn't released yet, I guess the answer is hard to give then, | 20:04 |
openstackgerrit | Jay Bryant proposed openstack/cinder-specs master: Move generic backup spec to untargeted https://review.opendev.org/679133 | 20:04 |
mnaser | jungleboyj: one node at a time? as in one service at a time? or one hypervisor at a time? | 20:04 |
jungleboyj | mnaser: One hypervisor at a time was what they were asking about. | 20:05 |
mnaser | you'll have to upgrade your control plane first, because ctlplane will be doing the translation, afaik you cannot run newer data plane than control plane | 20:05 |
