@adam:robins.wtfadamcstephensdoes a volume migrate with its instance across nodes?14:36:46
@hexa:lossy.networkhexawell, it does for the root volume14:37:11
@hexa:lossy.networkhexalet me test a custom volume14:37:16
@adam:robins.wtfadamcstephensyeah, but secondary volumes are a bit odd in incus14:37:23
@hexa:lossy.networkhexa

Shared filesystem are incompatible with migration.stateful=true

14:38:36
@hexa:lossy.networkhexaok, so block devices14:38:42
@hexa:lossy.networkhexa

Only additional disks coming from a shared storage pool are supported with migration.stateful=true

14:39:29
@hexa:lossy.networkhexayeah, ok14:39:38
@hexa:lossy.networkhexafucked14:39:41
@hexa:lossy.networkhexafirst error is for filesystem, second for block14:40:31
@hexa:lossy.networkhexaI wish they'd document limitations better 😄 14:41:22
@adam:robins.wtfadamcstephensopen a PR? 😉14:48:18
@hexa:lossy.networkhexayeah, that would be ideal14:50:01
@hexa:lossy.networkhexalol, so because a non-root volume may be used by multiple instances it must be on shared storage17:24:00
@hexa:lossy.networkhexathat's a fucking edge case17:24:10
@hexa:lossy.networkhexahttps://github.com/lxc/incus/issues/2102#event-1759423212117:24:20
@adam:robins.wtfadamcstephensyeah that seems a bit odd 17:46:26

@galaxyyy:matrix.orgSaturn I just updated my system to the latest unstable and I'm having issues with App Containers (OCI) not getting an IPv4 address. Has anyone experienced similar? 05:23:28
@galaxyyy:matrix.orgSaturn My normal system containers get one just fine but my app containers don't 🤔 05:24:55
@galaxyyy:matrix.orgSaturn Hmm https://discuss.linuxcontainers.org/t/oci-containers-not-getting-dnsmasq-entry/21627/3 running the command listed there temporarily (until a restart) fixes one or two of my containers that have that package... 05:36:05
@galaxyyy:matrix.orgSaturn Has anyone else had this issue? For the life of me cannot find a fix 17:23:29
@adam:robins.wtfadamcstephenssorry. i've never even tried the oci support. though you made me realize we have zero tests for it22:16:02
@c0ba1t:matrix.orgCobaltTil, that lxc had OCI support22:16:38
@c0ba1t:matrix.orgCobaltDoesn't seem to be a support backend in the containers module though22:17:20
@c0ba1t:matrix.orgCobalt* Doesn't seem to be a supported backend in the containers module though22:18:36
@c0ba1t:matrix.orgCobalt* Doesn't seem to be a supported backend in the virtualization module though22:18:54
@adam:robins.wtfadamcstephens Huh? 22:27:06
@hexa:lossy.networkhexaOCI is not virtualization but containerizationn22:29:14
@hexa:lossy.networkhexahence the name Open Container Intiativei22:29:34
@hexa:lossy.networkhexa* OCI is not virtualization but containerization22:29:41
