06:03 garbageyard Hi. I am trying to install GlusterFS on RancherOS but it seems the mkfs.xfs command isn't available. Any idea how i can resolve it?

06:44 Klas either use a different fs or install xfs?
06:45 Klas xfs is very commonly available, but, it's not that unusual to not include it in kernel/OS
06:49 garbageyard RancherOS is a very lightweight OS. I don't think it has any package manager. I could see mkfs.ext2, mkfs.ext3, mkfs.ext4 and mkfs.ext4dev but not mkfs.xfs
06:50 garbageyard GlusterFS mentions using mkfs.xfs only. Not sure if any other FS can be used
06:50 Klas any FS can be used as far as I know, xfs is recommended to get full functionality though (unless things changed)
06:51 Klas but don't take my word for it, and we are using xfs
06:52 Klas but unless I'm mistaken, any FS with extensible file attributes should be sufficient
06:52 garbageyard Ok. Does ext4 fit the bill?
06:52 Klas but, if you want to be safe, recompile kernel with xfs and add xfs support in general
06:53 Klas I think ext4 should work, but you should wait for someone who knows a bit more before putting too much time towards it ;)
06:54 garbageyard Not good with these kernel-level stuff and with RancherOS in place, my confidence is already shaking
06:54 Klas is rancherOS something akin to coreos?
06:54 garbageyard Yes
06:54 Klas meaning, basically something to launch docker from
06:54 Klas ah
06:54 Klas why would you run gluster on that?
06:54 garbageyard Meant specifically for Docker
06:54 Klas seems a very poor fit
06:55 garbageyard I too think so. It was told by client but i will check with them because this OS is really too minimal
06:55 Klas docker-specific OS:es are generally not suited for anything else
06:56 Klas and I would never, ever, run gluster in docker
06:56 Klas docker is basically designed to break =P
06:56 garbageyard :D
06:56 Klas it has many good uses, but all of them are based on it being scalable
06:58 garbageyard Our plan is to use GitLab along with Postgres and Redis (all as separate containers) and have GlusterFS for persistent storage. I have installed Kubernetes using Rancher server (which makes Kubernetes installation and managment very easy) on top of RancherOS. Plan is to have cluster of GitLab and Postgres containers for HA
07:00 garbageyard CentOS with Rancher server or just Kubernetes manual install might have been a better choice it seems. At least not RancherOS for sure
07:01 garbageyard Will talk to the client today
07:01 Klas can't you use mixed environment?
07:01 garbageyard Such as?
07:01 Klas gluster on seperate OS from the rest
07:01 Klas if the rest works, that is
07:02 Klas Most dists have a small images, debian or red hat both have small enough images to use without any real headaches
07:03 garbageyard Does it mean having few OS having Gluster installed and using their volumes mounted on the existing container?
07:04 Klas something along those lines, yes
07:04 Klas in general, in docker installs, you want to have DB and joint storage seperate from the containers anyhow
07:05 Klas since the containers breaking should never result in data loss
07:07 garbageyard Ok. True that data loss is the main concern. I think if the client agrees moving the existing setups to CentOS or something similar, that would be great. That way i could do away with managing extra amchines for Gluster

10:12 cloph garbageyard: re mkfs.xfs missing: that's typically just a matter of installing xfsprogs package - kernel will likely already have support for it.
10:13 garbageyard I did look on some pages and i did see that package but how do i install it on RancherOS?
10:13 cloph (remember to use big enough inodesize for extended attributes when using xfs, and also consider also larger dirsize)
10:13 garbageyard On any other OSs, there is yum/apt-get and other installers but not here
10:14 garbageyard On RancherOS, everything runs as a container
10:14 cloph no idea - why you're using an "exotic" OS to begin with?
10:14 garbageyard I have a strong feeling that this OS is not the right choice.
10:14 garbageyard Client's demand
10:14 cloph and "anything in container" sounds like a pain in the ass when you want two servers' containers to talk to each other, as gluster would require ..
10:15 garbageyard I have sent a mail to client sometime back
10:15 garbageyard Yes, that's true
