A little further improvement:

Instead of the find action...

-exec rm -f {} \;

you may use...

-exec rm -f {} +

which uses less rm calls since filenames to delete are added until the...

Since some time now docker is being on the fall and is being abandoned as provider for container technology.

Red Hat already threw docker out of its Red Hat Enterprise Linux (all Versions 6,7 and...

Hi tinfoil,

a) check the configured port speed on both sides


ethtool <yourinterfacename> | grep -iE "(speed|duplex)"


It should look like this:


ethtool enp216s0f1 | grep -Ei...

Hi,

the typical questions:


What are your operating systems?
What have you tried so far?


For a start, write a script maybe with awk or sed which does the change on the server for you...

VPN stands for virtual private network. The virtual means that this privacy is accomplished allthough it is by nature not private at all when you communicate over a public network - the internet....

Hi,

I just had a use case for encryption. I decided to use dm-crypt to create an encrypted container. It's fairly easy. You may just have an encrypted container for your live data and another for...

As I understood you, you like to combine 2 parts of 2 different disks into one partition/filesystem. You can do that(e. g. by using lvm). But if you do, know that one of those 2 disks fail, the data...

I got some advices from a person who wrote his thesis on the subject of benchmarking:


benchmark with the applications that are like the later used applications.
test with concurrent...

Hi,

I got asked if I can list some additional informations about ceph "in production" at my site.

Well, the small hyperconverged cluster here with ceph is not really in production by the...

From all my experience in linux I would assume yes. The better OSS pieces can be operated from rescue systems. But since I have very little competence in the area of those encryption techs, I can...

My test hardware is the following:



inxi -v2 -C -D -M -R

System: Host: pvetest Kernel: 5.3.10-1-pve x86_64 bits: 64 Console: tty 1 Distro: Debian GNU/Linux 10 (buster)

Hi,

I'm interested in storage benchmarks for various configurations in order to figure out what's best for a virtualization environment. The virtualization environment will be proxmox, as it is...

Hi Neo,

I assume nobody ever will do a migration/upgrade of a software like the vBulletin used at unix.com for a fixed price. That's beause I assume vBulletin here is absolutely heavily...

Two more comments on zfs:


Don't fill up the filesystems
If you fill up zfs file systems above 80%, performance will degrade.
No manual balancing method available
If you have a Volume with...

You say you were 100% sure this code works. Do you have the exact same environment as before? Same software? Same versions? Probably not.

traps_save() { saved_traps=\$(trap) ; export saved_traps;}...

Nice to watch and read the progress.

10 hours is a hell of a roundtrip time. Maybe 1000 or 10000 posts are enough per try ;-).

Hi,

In the past i participated sometimes at Monitoring Portal (https://monitoring-portal.org) . They changed to discourse 1-2 years ago. The usability seems fine for me. Since discourse is based...

insert set -x after the first line of your script, run it and check the different commands and if they do, what you are expect them to do.
run the commands one by one and later combined as up to...

New Customer: Houston we have a problem! Our webserver has strange delays and outages. Every day at the same time. Some minutes and then it goes away. We internally checked the configuration of the...

@Neo: That are definitely good points. Regarding performance, I do not need very high performance for my zfs servers, so I have no comparison to other servers using btrfs/ext4.

What's regarding...

Another comment:

A con against zfs is the inability to remove VDEVs. A VDEV is a subpart of a volume.

Example:

Say you have a data volume consisting of a single disk(=vdev, 1 TB). You...

I recommend to use awk instead of bc to calculate here, because bc displays floating point numbers <1 without a leading zero.

So your command ...

echo "`date -d $expdate +%s` - `date -d $today...

Hi,

I just checked your script on a linux system without any output with a file with 1/3 million words in it (filesize 2700 KB: I used this file: wordlist.xz (http://www.megabert.de/wordlist.xz))....

Encryption makes the backup task more difficult. That's why I avoid encryption except where I really have the need for it(which was never case for me so far, and thus I won't be helpful on the topic...

Hi,

some personal experiences and experiences from others:


zfs
I'm very fond of the ease of use of zfs administration. Few simple commands which all did what I expected them to do....
