$ split -b10G /dev/random &(you change the 10G to whatever size files you want created)
You can run this as many times as you need
fallocate -l 10G /filepathBetter fill disk with 3kB size files. Up to the brim.
Or unzip a zip bomb
RIP some oversold BF storage plan.
Hi,
if you really want to test it and f*** up your provider AND have a yearly plan, THEN you should wait some time ( so other customers will also start filling ) and then fill it.
Wont help you to make it full now, see that it can be filled and delete all again as right now it all might be still fresh and virgin empty on the providers storage. So an overselling might slip through your test this way easily.
Or... you will fill it and then delete as much as you actually need to store and then store the real files. -- Would require to know before how much space you need.
For profit Host and conservative greedy customer meet at LET. If everyone fill the HDD, RAM, start consuming reasonable CPUs, even exchange data, the power consumption will raise, almost DDOS the own server. Avoid it. Most people buy them just for adrenal rush or for network transfer like proxies or fun project. For sure, these providers not meant for stress testing.
Hi,
you have for sure a point.
But the topic opener has as it seems to me another goal. And its also understandable.
If you bought super cheap and doubt the provider, you have to test it before you use it for your precious data.
People write often "what do you expect from a XYZ EUR/USD server"... but i also have here another opinion.
The provider decided to give you tons of resources for virtually nothing. Thats the problem of the provider. Actually its the adrenaline rush for the provider, if x% of people will (hopefully) not use what they actually paid for...
I mean whats that? If you know/doubt as a provider that you cant deliver it, then dont offer it.
But, we are in times where every idiot can offer what ever nonsense and people will buy it, not thinking about if this is actually economically or even technically possible.
So, why not testing it? Not to disturb the neighborhood? Well... sorry, the offers does usually not say "X CPU Cores, Y GB RAM, Z GB diskspace ( only useable up to 10% )" so whats wrong if someone wants to know how heavy the system is overbooked or if the advertised resources are existing anyway.
FWIW, I wouldn't bother doing this on a new machine, but I'd almost always do it on a server that I'm about to get rid of after deleting anything important/sensitive, just to make sure that the next person to get the disk can't just read back my data. Nowadays, because most providers use NVMe and any TRIM'd regions will read back as zero when re-allocated, this isn't a big deal, but for spinning rust it's more important.
I think, for data backup, replication is very important, let us say, CEPH storage used for storage, the system was unit tested at code level, integration testing was done, the system must have at least 3 replicas, Hard disk/storage must have raid array. Also host don't advertise for fault tolerance, HA etc. I am still doubtful to rely on low end hosts for life long storages if someone very serious about their own data at low budget. I think, at lowendhosting, as long as things works, we seems to be lucky. Microsoft like providers offer office 365 with 1 TB or 5 TB sizes, most trustable if the storages are really important.
if I have used 3.2TB+ out of 4TB allocated, that is good enough test for me.
I just think it would be interesting to fill every server and see if any provider says anything especially when I’m on the fence on which monthly ones to get rid of.
But thanks for the replies. Looks like some easy enough methods.
Open your IPMI to the pubic internet, and JungleSec will take care of filling the diks.
What is the point of filling disk with useless/random data - how you gonna verify it's really there?!
aka China SDcards :-D?
while true; do touch $(uuidgen); done
At least for inodes.

I personally wouldn't rely on , say , CEPH or RAID from providers, whether it's expensive provider or economic provider.
but I do get the part of replication , I'd rather have same copy saved on multiple storage servers across different regions.
