NVMe and SATA health data on ESXi: some links to investigate

Posted by jpluimers on 2021/08/25

(Edit 20221202: added one more link on “REALLOCATED SECTOR CT below threshold”)

Somehow, health data of my NVMe and SATA drives do not show up as health information on the web-ui of my ESXi playground rig.

So far, I noticed that ESXi runs a smartd, but does not ship with a smartctl, nor health data ends up in the web user interface. So you cannot see the state of NVMe and SATA devices easily.

Still these devices deteriorate over time and afterwards die, so below are some links to investigate later.

Goal is to use my own thresholds to set warning and error levels.

Some log entries:

Better disconnect your Samsung TVs from the internet, as they can remotely disable them for whatever reason they see fit

Posted by jpluimers on 2021/08/25

Oh nice: [Wayback/Archive.is] Samsung can remotely disable their TVs worldwide using TV Block.

This means:

Disconnected, any apps needing internet connection won’t run.

Those apps usually work more reliable on an Apple TV or similar device that plays over HDMI anyway.

In addition, it will also prevent Samsung to show adds on your TV.

So disconnecting it is a win-win-win situation.

 

Note: you could already block apps and adds, see:

Maybe those blocks also block blocking.

html – CSS Display an Image Resized and Cropped – Stack Overflow

Posted by jpluimers on 2021/08/25

[WayBack] html – CSS Display an Image Resized and Cropped – Stack Overflow (thanks [WayBack] roborourke!); see full answer link for runnable snippet and HTML (the WordPress editor keeps fucking up preformatted code blocks with html or XML in it).

You could use a combination of both methods eg.

    .crop {
        width: 200px;
        height: 150px;
        overflow: hidden;
    }

    .crop img {
        width: 400px;
        height: 300px;
        margin: -75px 0 0 -100px;
    }

You embed the img in a div with class .crop, or in-line the styles in the img and div tags.

linux – How can I find all hardlinked files on a filesystem? – Super User

Posted by jpluimers on 2021/08/25

[WayBack] linux – How can I find all hardlinked files on a filesystem? – Super User

use the following line (for sure you have to replace /PATH/FOR/SEARCH/ with whatever you want to search):

find /PATH/FOR/SEARCH/ -xdev -printf '%i\t%n\t%p\n' | fgrep -f <(find . -xdev -printf '%i\n' | sort -n | uniq -d) | sort -n

this scans the filesystem only once, shows inode, number of hardlinks and path of files with more than one hardlink and sorts them according to the inode.

if you are annoyed by error messages for folders you aren’t allowed to read, you can expand the line to this:

find /PATH/FOR/SEARCH/ -xdev -printf '%i\t%n\t%p\n' 2> /dev/null | fgrep -f <(find . -xdev -printf '%i\n' 2> /dev/null | sort -n | uniq -d) | sort -n

It uses these commands:
