I am a noob with RancherOS, plus maybe a noob with containers too, and want to learn and play around.
I have a microserver with 1x32GB USB thumb drive and 4x2TB disks.
I have installed RancherOS on my 32GB USB thumb drive.
now I want to create a raid partition of some kind from the 4x2TB disks. I have tried zfs and followed the article “http://rancher.com/docs/os/v1.2/en/storage/using-zfs/”, but on reboot, the zfs volumes do not mount. I googled and searched and tried various scripts, to no avail, so, gave up on that.
next I tried software raid, but as i didn’t understand that too much, I gave up on that too.
now i want to try LVM, and, as far as i can tell, it is natively supported, so i created a lvm (/dev/vg_pool/Data formated it with ext4, and mounted it at /mnt/data. i followed the advice at “http://rancher.com/docs/os/v1.2/en/storage/additional-mounts/” and used ros config to set the mount, then rebooted. however, the volume did not mount. running a lvscan showed the volume as inactive. i have to manually activated it, and mount it, and the world was good.
what i have trying to do is ultimately move my default docker “folder” to /mnt/data so that i will have a lot of disk space to run and play with various containers.
any ideas or articles that i can be pointed to will be greatly appreciated.
maybe i am going about this the wrong way?
