Hi Amine,
|
||
|
|
||
|
thanks for your kind words!

I've been very impressed by how well Btrfs handles extensibility. I have
|
||
|
recently thrown new drive at my setup. The main advantage of Btrfs in my
|
||
|
opinion is that you can combine any drives you want, as opposed to ZFS,
|
||
|
where you're more or less constrained to drives of the same size.
|
||
|
|
||
|
Regarding RAID: You're right, RAID 5 is unfortunately still unstable.
|
||
|
After one year, I don't regret going with RAID 1 (mirrored) for my
|
||
|
setup. If you have 4+ drives, I suggest you take a look at RAID 10,
|
||
|
since it gives you some advantages over RAID 1.

Great choice! Backblaze has been rock solid for me as well. And they're
|
||
|
cheap too!

This is a topic I haven't dipped my toes into yet. All of my drives are
|
||
|
unencrypted. Thanks for your recommendations though, I will have to look
|
||
|
those up! Are you using restic in your current setup?

Some time ago I wrote up a blog post about using healthchecks.io with
|
||
|
docker:

|
||
|
|
||
|
healthchecks.io is really neat, since *you're* responsible of pinging
|
||
|
their endpoints, as opposed to *them* pinging a HTTP-endpoint. This
|
||
|
enables you to write Cron-scripts that frequently check the health of
|
||
|
your drives. I'm currently using this script to check my drives:
|
||
|
|
||
|
```
|
||
|
#!/bin/bash
|
||
|
|
||
|
curl -fsS -m 10 --retry 5 -o /dev/null $PING_URL/start
|
||
|
|
||
|
output=$(btrfs scrub start -B /var/anubis)
|
||
|
|
||
|
curl -fsS -m 10 --retry 5 --data-raw "$output" -o /dev/null $PING_URL/$?
|
||
|
```
|
||
|
|
||
|
maybe it's of use for you?
|
||
|
|
||
|
Thanks again for your comment!
