PSA: Check your S.M.A.R.T disk health regularly...

[1337]

Hey,

Just a quick reminder to everyone that drives do unfortunately hit old-age and failing states, and that it might be worth a quick check of your current nodes to see how their status is. Just making this as a recent backup node I picked up from SoYouStart is detecting as oldage and failed (wouldn't expect that from OVH??) and had I not ran the scan, it would've easily gone undetected until it was too late and client data could've been lost.

Instructions for how to check your disk health can be found here for Ubuntu and debian systems:

1. apt-get install smartmontools

2. lsblk (shows you all partitions in a format similar to this, pick your primary one for the next step, in our case it was /dev/sda: https://i.unreliable.host/Termius_2019-01-05_20-55-54.png)

3. smartctl -a /dev/sda {replace if needed with results from prior command}

Hope this helps someone, feel free to DM me on MCM (or discord, david#0101) if you have any questions or need help checking a disk's status.

I think this post is a really good idea because some companies do use very old drives especially so you start storage servers
