Funtoo Linux BDFL drobbins Posted February 5, 2018 Funtoo Linux BDFL Report Share Posted February 5, 2018 Hi All, We have deployed our second-generation compute infrastructure and have begun the process of moving containers over to it. This funtoo-based infrastructure is running on faster hardware and is using ZFS for storage. For more information on our second-generation platform, see https://www.funtoo.org/Funtoo_Containers Also note that plans have been upgraded. Our base plan for $15/mo now comes with 8 cores and 60GB of storage (was 6 cores and 50GB previously.) The medium plan now has 16 cores and 120GB of storage (was 12 cores and 100GB). And our large plan now has 32 cores and 240GB of storage (was 24 cores and 200 GB). All existing containers will be automatically upgraded to these new resource levels when they are migrated to the new infrastructure :) Best, Daniel tux and dkg 2 Link to comment Share on other sites More sharing options...
tux Posted February 6, 2018 Report Share Posted February 6, 2018 Hi Daniel, Do we need to expect a downtime/reboot during the migration ? I'm going to backup some files just in case :) Funtoo container plans are truly impressive ! Link to comment Share on other sites More sharing options...
Funtoo Linux BDFL drobbins Posted February 6, 2018 Author Funtoo Linux BDFL Report Share Posted February 6, 2018 Migration typically involves 1-5 minutes of downtime. Typically if you do not have a ton (like 100GB of data) the downtime is closer to one minute. So pretty painless. Link to comment Share on other sites More sharing options...
s4uliu5 Posted February 7, 2018 Report Share Posted February 7, 2018 Hi Daniel, very interesting news! Does it mean that OpenVZ kernel will not be supported/updated, at funtoo, anymore? And if anybody is using OpenVZ right now should plan/start migration to LXD? And just curious - why LXD? Thank you! Link to comment Share on other sites More sharing options...
Funtoo Linux BDFL drobbins Posted February 10, 2018 Author Funtoo Linux BDFL Report Share Posted February 10, 2018 We will continue to support the OpenVZ RHEL6 kernel. This kernel will still be maintained upstream for several years. LXD runs on newer kernels and is getting mature enough to use in production, so it worked well for us.

Funtoo Linux BDFL drobbins Posted February 12, 2018 Author Funtoo Linux BDFL Report Share Posted February 12, 2018 One note that when we upgrade to core-kit-1.2, the minimum kernel supported will be linux-3.2. This upgrade should be happening within a week. You can choose not to upgrade and stay at core-kit 1.0 if you need OpenVZ RHEL6 compatibility. So it does appear that we will be moving away from OpenVZ for our default build. Link to comment Share on other sites More sharing options...
haxmeister Posted February 13, 2018 Report Share Posted February 13, 2018 The upgraded container is running well.. the performance is fantastic, thank you! Link to comment Share on other sites More sharing options...
palica Posted February 14, 2018 Report Share Posted February 14, 2018 There is more to come such as running LXD inside you container, or running Docker inside your container, or even running VirtualBox inside your container. Teaser: Ubuntu inside VBox inside my container. Link to comment Share on other sites More sharing options...
ennui Posted April 18, 2018 Report Share Posted April 18, 2018 My container was rebooted on Apr 17 22:36 UTC. Previously, my dovecot installation was non-functional since the migration to LXD, as execv() calls to dovecot's helper processes were failing. Now, after this reboot, dovecot is working as expected again. Was there a mandatory access control (MAC) or some other restriction mechanism in place on the host system?

palica Posted April 19, 2018 Report Share Posted April 19, 2018 yes, apparmor was blocking dovecot. Link to comment Share on other sites More sharing options...

erikr Posted May 31, 2018 Report Share Posted May 31, 2018 Just to clarify, will I be able to make snapshots of / from within my container or the management console? Link to comment Share on other sites More sharing options...
palica Posted May 31, 2018 Report Share Posted May 31, 2018 this is planned through irc robot. including restarts of container. and other stuff. it is WIP. Link to comment Share on other sites More sharing options...

Cool, I am always hesitant to get started with updated unless there is a snapshot available to role back to. Or even better a snapshot to make the upgrade in until it is successful.

palica Posted June 1, 2018 Report Share Posted June 1, 2018 i can create a snapshot for you right now if you want. pm me on irc. Link to comment Share on other sites More sharing options...
ennui Posted November 19, 2019 Report Share Posted November 19, 2019 @palica @drobbins: Is AppArmor blocking Dovecot again? I see my Dovecot processes went down around 2019-11-18 01:35:01 UTC: Nov 18 01:35:01 [dovecot] master: Warning: Killed with signal 15 (by pid=21330 uid=0 code=kill) Subsequent attempts to restart Dovecot are failing: # /etc/init.d/dovecot start Fatal: execv(/usr/bin/doveadm) failed: Permission denied * Error parsing /etc/dovecot/dovecot.conf * ERROR: dovecot failed to start Link to comment Share on other sites More sharing options...
palica Posted November 21, 2019 Report Share Posted November 21, 2019 @ennui sorry don't have access to funtoo infrastructure anymore. you'll have to wait for drobbins to answer this one. ennui 1 Link to comment Share on other sites More sharing options...
Funtoo Linux BDFL drobbins Posted November 22, 2019 Author Funtoo Linux BDFL Report Share Posted November 22, 2019 @ennui AppArmor is enabled again, and for a bit the dovecot mess resurfaced. But I disabled the dovecot profiles this should have already been resolved. If necessary, reboot your container and it should be fine. ennui 1 Link to comment Share on other sites More sharing options...
