Those dudes probably don't know how to make the difference between file cache and memory usage. All computers including those using Linux will use ALL their memory for file caching e.g. caching the content of files into memory.

Here is an example:
free -h
                                                        total used free shared buff/cache available
Mem: 7.8Gi 617Mi 586Mi 53Mi 6.6Gi 6.8Gi
Swap: 15Gi 66Mi 15Gi

This computer has 8GB of memory, ~586MB of free memory, and ~6.8GB of available memory because it uses the spare ~6.6 GB for file caching, all OSes do that. That memory used for file caching is available instantly for the OS at anytime and must be excluded from the memory the OS uses. All spare memory will eventually go to file caching. Again all OSes work like that.

So 8GB ram 586MB free and 617MB used by the OS and running programs so 6.8GB available

So you need to be able to tell the difference between free memory (you shouldn't have any or very little if your OS works correctly) and *available* memory. That memory used for file caching is avaiable on demand at any time for the OS and running programs

Also don't look at "virtual memory" used you need to look at "resident memory"

Example:
On the same host as above:
1004 mysql 20 0 1759176 355056 7560 S 0.0 4.4 61:13.76 mysqld

mysqld uses 1.7 GB of virtual memory but only 355MB of resident memory. That 1.7GB of virtual memory doesn't really matter. All OSes including Windows work the same way although they often name thing differently. You need to know how to interpret what you see...

It's normal that any OS will have close to 0 free memory! This is the expected behavior. See my other post just above.

Very clever move from Mark Zuckerberg because mongoDB is web scale thus perfect for the meta-verse.

That's not true, in the big cloud company I work for all our 286s MFM hardrives now use upgraded RLL controllers.

Who is "they" ????

Nobody but me has physical access to that server and it doesn't accept any connections from anywhere. But yeah, you could set zfs permissions for that and use a non-root user if you wish.

You need to make a clone of a snapshot. Then, you write that to tape, then you need to make at least md5sums of the disk image or of each file on the clone, read the tape you just wrote and compute checksums of the tape as well, then finally compare the checksums.

That's always what I did when using tapes and that's still what I do with usb connected hard drives I use nowadays instead for critical stuff on top of what I described above.

I have had and I still get regular but very occasional checksum failures comparing. You can't just write to tape and consider it a valid backup without comparing with the original before putting it away and moving it to a different location. When I get a checksum failure, I run the test again to make sure I get the same exact two different checksums again to insure the problem doesn't come from another hardware component like memory scsi/sata/usb controller, bad cable etc. etc.

While at it, take snapshots on the remote server to prevent against ransomware attacks and your prod server shouldn't have any access to the replication server in a different geolocation otherwise hackers will delete/encrypt data on the replication server too. The replication server should pull the data from the prod server with something like this:

CMD_OUTPUT=`ssh -C -l root -p 52812 $HOST zfs send rpool/data/${ZVOL}@${NEW_SNAP_NAME} | zfs recv rpool/datarep/${ZVOL} 2>&1`

I know it's possible to give the prod server access to the replication server like in the proxmox backup server architecture and set permissions on the replication server so snapshots can't be deleted but I find it much more safer to protect the replication server in its own VLAN and protect it almost like a CA and insure nobody and nothing has access to the replication server.

More on topic, I think cloud customers should be aware that if their datacenter is destroyed, they *will* lose data if they didn't take care of replicating their data to a different geolocation.

Exactly the same happened when an OVH datacenter caught on fire in France. Many customers which didn't have replication set to a different geolocation lost their data. Heck a dude I know had backups on different servers in the same datacenter which turned out to be useless.

I replicate my filesystem to different geolocation at least every 10 minutes and I have pseudo real time replication (usually below 1 seconds) database replication with log replay.

Me neither but I ordered 3 dozens to take the RAM out of them and put it in my Beowulf cluster. At $1,299 for 1TB, it's really a steal at that price for 1TB

From TFS:

Indeed, a tty? who needs that? I just catch the keyboard interrupt and I write directly to B000:0000 memory address to display output.

My cell phone is pretty much blank since I barely use it for anything but phone calls. People don't even text me since they don't have the number and the ones who do know that I don't check it regularly and that it's often completely off. I have a ring group on my PBX which rings my cell phone as well.

Try with such a phone at a border crossing to see how much suspicion you will raise! They then go into more detailed questioning and verifications etc. I now have to put *some* stuff on it not to raise suspicion and get through more quickly.

You will be lucky if you find an old copper penny nowadays. They haven't been made out of copper since quite a while.

No, if that current collapse, Europe is going to freeze. That current cools down Northern America and warms up Europe. That's why you have snow storms and it's cold in Montreal in the winter while comparatively a lot warmer in Paris France and Paris is farther up North than Montreal.
