We finally got the parts in the machines. How would you like the disks to be
configured in the HW RAID? RAID5, RAID6? RAID10? Also, I'd imagine you want this

if so what?

Hmm, we plan to run Ubuntu 18.04 with ZFS so that we can easily do lxd
containers. Last I checked installing ZFS during install was kind of
annoying, so maybe a small slice off one drive as ext4 for the OS and
the rest ZFS post install. In which case the "Raiding" would be done via
ZFS in software?

I'll let someone chime in if that doesn't sound right.

Thanks,
Alex

So it sounds like you want the server setup with a JBOD (just a bunch of disks)
effectively making each disk visible for ZFS and no HW RAID. Unfortunately, the
disk controllers technically don't support JBOD, however we can work around it
by setting up each disk as a RAID0 device. This is what we do our Ceph storage
nodes and it works quite nicely. It also allows the disks to use the HW RAID
cache.

Do you want me to attempt to do a rootfs on ZFS or try and keep it simple and
just do a RAID1 with the first partition on two or more drives, and leave the
rest of the drives for ZFS?

Except you can't do that until after install. We're talking about /
being on ZFS, there's a old thread and maybe even a wiki page with
links. It was sufficiently complicated that we skipped on OSGeo7 for now
and put / on other disks.

Thanks,
Alex

Regina,

Do you have an opinion on this, since you setup OSGeo7, what would give
you the most similar layout?

Sorry I guess I missed all this discussion.

For the OSGeo7 we had 500GB allocated for root, and the rest of the disks were set aside for ZFS.

I think a similar setup will work. Note the 500 GB is useful for exporting images so I'd like at least that much separate from our lxd ZFS pool. It doesn't need to be the root drive and doesn't really need mirroring either.

I think going with RAID0 is probably the best.
Also last time we did this -- you just inserted the Ubuntu 18.04 disk in the CD tray and we took care of the installation.
Not sure if that is doable or if because of the way the RAID is setup that's not doable.

Thanks,
Regina

Based on what I mention below, how do you want the physical disks setup with
regards to the HW RAID? Should the rootfs, should that have any RAID and if so
what? You mentioned RAID0 above, I wasn't sure for which volume. Also, I'm not
sure how OSGeo7 was configured as far as HW RAID and disks.

Lance,

By RAID0 I meant by what you suggested below:

As for the OS that won't be under ZFS will a regular extfs partition, so maybe a RAID1 (is that what you were suggesting)?
I suppose having some level of redundancy for the root partition would be good since we won't have that under ZFS.

Hope that clarifies things,
Regina

By RAID0 I meant by what you suggested below:

As for the OS that won't be under ZFS will a regular extfs partition,
so maybe a RAID1 (is that what you were suggesting)? I suppose having
some level of redundancy for the root partition would be good since we
won't have that under ZFS.

Hope that clarifies things,

Yes that does! I'll get that going later today or tomorrow. What ssh keys should I put on the system so you can access it?

Thanks-

This system has been finally setup. You should be able to access it using the
tech_dev user by going to osgeo4.osgeo.osuosl.org. I've disabled password logins
via ssh but have added the ssh keys you sent to the tech_dev user. The password
for the user is 'oaDOGqlWNRMvgqXY9XCc' which you should change once you login.

Here's how I setup the system:

root@osgeo4:~# lsblk -i
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 1.8T 0 disk
|-sda1 8:1 0 953M 0 part
| `-md0 9:0 0 952M 0 raid1 /boot
`-sda2 8:2 0 46.6G 0 part
  `-md1 9:1 0 46.5G 0 raid1
    |-lvm-root 253:0 0 37.3G 0 lvm /
    `-lvm-swap 253:1 0 7.5G 0 lvm [SWAP]

`-sdb2 8:18 0 46.6G 0 part
  `-md1 9:1 0 46.5G 0 raid1
    |-lvm-root 253:0 0 37.3G 0 lvm /
    `-lvm-swap 253:1 0 7.5G 0 lvm [SWAP]
sdc 8:32 0 1.8T 0 disk
sdd 8:48 0 1.8T 0 disk
sde 8:64 0 1.8T 0 disk
sdf 8:80 0 1.8T 0 disk

Both sda and sdb have 1.9TB left to be allocated via a partition that you could
use for ZFS. Please let me know when you're able to login and able to gain root
access.

Thanks-

tech_dev user by going to osgeo4.osgeo.osuosl.org.

Thanks again for the setup. Can we have KVM access as well.

In osgeo7, we were given - https://osgeo7.osuosl.oob/

Which allowed us to access via the KVM interface to do hard reboots. This are able to access using the OpenVPN connection of OSUOSL.

Can we have similar for osgeo4?

Thanks,
Regina

Sure thing however I need a way to get you the password. It seems the osuadmin
account on osgeo4 is no longer working with the key I expected. I can either
send you it via a gpg encrypted file (would need a key ID for that), or if you
can add our ssh key to the osgeo4 host and then I can copy a file with the
password there.

Let me know which way works.

Thanks-
