@hobbit666 said in GDPR galore:

Yeah I've been hearing a lot on this GDPR stuff luckily I'm not involved and others in the dept are lol.

But what logs would they need you to collect and store? We don't do this at the moment but if required would like to start looking at solutions. So I'm prepared for the "can you do this and get it installed" lol

Bah. Here in italy they are stressing a lot the access control. And they want centralized lig inspection to check for logins (not necessarily a valid point from a tech perspective but they ask for)

@scottalanmiller basically any clevo reseller has those models, so you can find the one colser to you (duties).
btw for personal experience nothing is as solid as a dell/hpe/lenovo enterprise lines chassis-wise. Clevo stuff is nice but a bit more weak.

That's why I asked if you have better knowledge of community on this solution because I really don't. So if it's the case, that it's not stable (darn, it's here since a long time!), that's indeed not an option.

Issue with HA lizzard is that it doesn't have a stateful quorum system (just pinging a single IP address). You can split brain it.

Afaik latest ha-lizzard docs suggest to work in active-passive only... There must be a reason...

first computer I used: Philips MSX

first pc I owned was a withe box w/ Pentium I MMX.
In the middle I played with Commodore Amiga 500

@dashrender noob question: which is the equivalent of cat /etc/version on win powershell?!

@tim_g said in Veeam Backup and Replication for ESXi:

I don't hate Veeam. I just hate how they support some of their products.

They will support it, you are just not willing to pay....

I think what @Tim_G says is that he has the perception that Veeam releases the linux agent for free but then doesn't care about maintaining it compatible or giving proper support in the community . He probably refers to the difference found in support forums between a free commercial product and a proper opensource product with its own community. Two very different beasts IMHO.

I've just tried their agent for windows once and never looked in it soo much, therefore can't say.

The only think I know is that breaking a linux machine is quite hard to me and I tend to use stuff like rsnapshot for my spare time stuff... and a clonezilla just a beginning of a new deployment (just in case). All my SMB workloads are VM running agentless backups with Altaro at HV level. And my linux VM are all deployed with Ansible now so I really don't mind so much about more complex backup solutions for Linux.

I mostly mind for windows... 'coz it really scarries me :-s !

@olivier YUP! it seems I was wrong. Red Hat has evetually rewritten it! In Python!

@dbeato yeah! they used a forked version of minix! best in breed for security auditing

Always managed w/out domain in my case so following things could be useless but... Did you enabled winrm both on server and workstation?

Too bad ovs isnt in the repos for RHEL/CentOS. You can set up these private networks and connect them through a VXLAN with ovs. That way you can have something like a separate dev network on the same hosts and they can communicate between hosts.

Not available in the epel repo?

That is apparently the case unless my google--fu isn't up to snuff

Nope. It is available in Fedora though. If you want to install it you have to manually build the RPMs. While not hard to build it would be a pain to maintain updates.

OVS is used by oVirt so maybe the centos ovirt repo has it (or the ovirt stable repo)

ou have something like Pi 3 and if so why ? and what OS on it ?
If you want to buy one which one interests you.
Thanks.

Raspberry Pi3 for thermostat and Arduino for door automation.

Why I am getting the vibe here that it is easier to code and automate with Arduino , is there an easy guide/wizard for it that does not involve alot of coding ?

Arduino is microprocessor coded with a specific dialect of c as most of micros todays. It is not able to run an os. Like any micro it accepts an entry point and starts looping the same code again and again until you pull the plug.
Raspberrypi is an arm architecture able to run an os. You can code it even in python or node.js

@scottalanmiller I know. I always prefer postgres when available. but there is a chicken-egg problem: small companies buy software from small devel companies which - for whatever reason I don't know- develop only in .NET with MS SQL.
there is a claer trend here in Italy. Therefore you have to bump the specs for the oversized framework.

@scottalanmiller said in What's the Best Way to Deduplicate & Organize Files/Folders on a 200 TB NAS?:

@dbeato would need 256GB of RAM to attempt that with ZFS. That's a lot of RAM on a NAS.

How did you get 256GB of RAM needed?

That FreeNAS article recommends 5GB RAM per 1 TB of deduped data...
Considering he has 200TB of data he'd want to dedup, that's at least 1TB of RAM to start.

This is because dedup on ZFS/FreeNAS is much more RAM intensive than all other file systems. (and also because 200TB is a ton of data)

What caused it to balloon so much recently? Traditionally it has been 1GB per 1TB.

https://serverfault.com/questions/569354/freenas-do-i-need-1gb-per-tb-of-usable-storage-or-1gb-of-memory-per-tb-of-phys

Freebsd zfs page stated up to 5gb per 1tb last time I checked

The starwind dedup estimator can be a thing here?!

The main reason node was developed was its author did liked the scaling capabilities of apache! If you never hit scalability limits of ngnix or apache the remaining reason for node is you are a fullstack devel and your mind twists jumping from a front end language (js) to a back end one.

Scott is right. When in dubt use rsync. Anyway cp is faster then the delta algo of rsync. Therefore the basic rule -if you care- should be: first time you copy go cp then always rsync. Even if cp fails you can restart with rsync.
But basically you do not bother and you go straight w/ rsync.

@DustinB3403 : Docker is a specific type of container. It is stateless (can't store data) and as any containers is omogeneous - unless you run it in a VM an entire host must run the same os.
In an SMB usually we have "thick" VM with all layers in (data, business logic, front end maybe) also we have either linux or win on the host.
From a tipical SMB IT Docker is of minimal use.
In bigger envs where your services are split in components and you have a lot of instances running on top of a backing store that make more sense.

@stacksofplates said in GitLab Symlink folder to another project?:

Use submodules for this.

git submodule add https://gitlab.com/<user>/repo repo

Yes submodule is the right way. Isolate common code into a library. Make a git for the lib. Submodule it in both of your projects.
