What OS are you using?
a
I'm using openSuSE microOS.
b
I need to investigate this, can you point me to the tigera docs where the ipset version is mentioned?
Canal is basically using calico for network policies, which is what uses 
ipset
, so migrating to Calico CNI will not help you though
what's the error you are seeing? kube-proxy is also using 
ipset
and I wonder if you are also seeing problems there
a
https://projectcalico.docs.tigera.io/release-notes/ shows ipset 7.11 support. The exact error message I see in the rke2-calico logs: 2022-10-08 184514.601 [INFO][31580] felix/ipsets.go 312: Retrying after an ipsets update failure... family="inet" 2022-10-08 184514.602 [ERROR][31580] felix/ipsets.go 574: Bad return code from 'ipset list'. error=exit status 1 family="inet" stderr="ipset v7.1: Kernel and userspace incompatible: settype hash:ip with revision 5 not supported by userspace.\n" 2022-10-08 184514.602 [WARNING][31580] felix/ipsets.go 322: Failed to resync with dataplane error=exit status 1 family="inet" This repeats endlessly. About the migration issue: I see no such messages in the calico-node pod on one of my other clusters. The above messages only appear in the one one with the rke2-canal installation.

let me try to reproduce it
I can't reproduce it with microOS 5.2 using kernel 
5.3.18
, what version and kernel do you have?
a
Thanks for the time you take on this.

thanks, that's pretty new! Note that the OS not under the support matrix https://docs.rke2.io/install/requirements/#operating-systems
I will anyway try to get a system and reproduce the bug
a
That site does not even mention openSuSE microOS, just the SLE microOS. I failed to find how my microOS version relates to the SLE microOS
I see that there is an openSUSE Leap micro 5.2 available, which - if I understood correctly - is an openSUSE equivalent of SLE micro 5.2. SLE micro 5.1 however has no such openSUSE version. Is that correct? (I know this is an OS question, but maybe you have this information)
c
you should rather use openSUSE Leap Micro indeed
5.3 should become available soon
openSUSE MicroOS takes a similar approach to Tumbleweed, it's using a rolling release model
a
Thank. Am I correct in that Leap Micro does not have a 5.1 version?
c
no it does not, but you should stay away 5.1 which is soon EOL
correction 5.1 is EOL already
no my bad, I was reading the wrong column
5.1 EOL is 31/10/2025 & 5.2 is 30/04/2026
but Leap Micro is only built from 5.2 indeed
a
That's exactly what I wanted to ask, but you were faster
