80 bucks. I am not sure if the seller knew of the problem or just one of those buying electronics used problems that can and do happen.
Anyone here use Ceph much? I am trying to design a cluster and was reading up on the docs, but one thing caught my eye.
I would love to have a separate drive for the journal and WAL file, but it appears that the file system is expecting a caching device per OSD (per disk) instead of per machine. This isnāt so much an issue, except I donāt want to have to have one caching device for each of the 8 hard drives in each of my servers.
Am I just reading this wrong? Is there a better way?
Messed with it a bit, good all in one distro for that.

When I was working with ceph, we didnāt use caching. It just increased latency and complexity.
Whatās the use case where you think caching would benefit you?
Random VMās disk images. Nothing in particular, but it will be a mixed bag of web servers, databases, game servers, stuff like that. I donāt need super high performance, just āok-ishā performance.
I plan on using spinning rust (10k SAS drives) with the array, and was hoping to use SSDsā as a write cache to help mitigate the latency of the distributed writes.
I donāt really know if I need it though. This is my first time working with Ceph so I donāt quite know what to expect.
Running into an issue were if my FreeNAS and Plex boxes restart at the same time I need to run a quick mount -a to get the media share mounted. Anyone know of an easy method of getting a script to run x seconds after reboot and run the mount command on Ubuntu 20.04?
Crontab

Is there a method of using crontab to run X time after reboot, rather than at X time on Y day?
EDIT: Ah, so @reboot is just uncommon. I swear Iāve looked for this before 
lol
I would recommend creating a systemd override file to tell the Plex service to wait for the data mounts to complete before starting.

I would see if you can get a systemd automount to work for you. Then it wonāt mount until something attempts to use it. It will also block whatever is attempting to use it until the mount completes, or times out. I find it super useful.
You can read man systemd.mount and look in the FSTAB section for mount arguments.
Here are a couple of automount lines I use on my Fedora server:
LABEL=Backup /mnt/backup-2 ext4 defaults,noatime,nodiratime,noauto,x-systemd.automount,x-systemd.device-timeout=999h,x-systemd.idle-timeout=5m,nofail 0 2
/home/zlynx-dropbox-ext4.img /home/zlynx/Dropbox ext4 defaults,noatime,noauto,x-systemd.automount,x-systemd.mount-timeout=6m 0 0
I made these automount because if thereās a sudden power failure or crash, these devices need to fsck before mounting. Because of all the other disk activity during boot my Dropbox loopback mount was actually timing out while mounting. After making it automount it doesnāt take effect until something starts using it, long after boot finishes.
The backup mount is similar. There is no point in mounting the backup drive unless it is in use.

100 iops per disk divided by replicas.
You donāt need it technically. I would just hold off on that. I think youāll find that ceph isnāt really great for your use case, after a couple months. Unless the whole point is to learn ceph for prod use later.

any one care to help me figure out why iām only getting 11 mega BYTEs a second on a new SMB / server setup that was maxing out my 1g network before?
In a couple of hours Iāll be 24ā¦
I hate it so much, not because I āfeel oldā, but because Iām not a young kid anymore.
I feel like the only thing I had for myself was to know that much, at my age. That was somehow who I wasā¦ Now that my work donāt give me time to learn about very low level, or any highly specialized field, āwho I amā is becoming less and less notable.
Now I need something else to be proud about, and no idea where to start looking 
Maybe getting into freelance, creating infrastructure that I can be proud of for clients, one after the other ā¦
Looking at rebuilding my current home server setup from scratch. Does anyone know of a good self hosted LDAP/SSO solution? Looking to have the root of the site go to a login page, then use a service like Nextcloud or Heimdall or similar to give links to services allowed to people.
A single sign on style option for the site and services as a whole would be ideal. Willing to learn anything it takes.
Freeipa?

Will give it a look over, seems good so far. Cheers

Or Samba AD (or both of youāre a masochist).
Also what flowchart software are you using there @MrBannaner ? Iāve been trying a few but havenāt found a definite favorite yet.
Late 20s were the most fun years for me. Just think up things and go do them while you have few responsibilities.

I use Samba AD at homeā¦ for one [sometimes] MS Windows computer.
Am I a masochist? Maybe. But now, I know how to do this.
