Whats the faster VM storage on Proxmox

ZFS, BTRFS, LVM, Directory. There are many options for storing VM images on a disk in Proxmox and other KVM based hypervisors. In this video, I take a look at the features and performance of all of these different storage methods.

For my test system I used a Xeon E5 2643 V4 system running Proxmox VE 7.2-7 with 128GB RAM, and a PM1725 as the test ssd.

Finally a video that is straight to the point on what I wanted to know. Thank you

I feel like i have learned more from this 8:55 second video than i have scouring forums for hours and piece mealing things together. thank you for the straight forward video.

Not gonna lie...I need a whole new vocabulary lol. Thanks for the explanations. I kind of dove face first into the world of Virtualization and wow do I need an adult. I bought some pc guts off a coworker for $500. 64 x AMD Ryzen Threadripper 2990WX 32-Core Processor, 64 Gigs RAM (forgot the speed/version), and an ASROCK MB. I threw in 24TB of spinning rust and now learning how to VM/setup an enterprise. End goal...stay employed lol. Thanks again for the help.

Thank you once again for the excellent video and for sharing your knowledge with the community.

[BenRook]

Nice presentation of what's available and pros/cons... good vid!
Will stayed tuned for future content...thx.

For those interested, Wendell just did a "what were learned" review of Linus' (LTT) PetaByte ZFS drive failure - "A Chat about Linus' DATA Recovery w/ Allan Jude" - ZFS got another development boost (with more coming) as a result ..

Really love your content i hate that channels with way less info but just do flashy edits get the attention when the guys that know their shxt don't get the same views

[theundertaker]

Thank you for an amazing, straight to the point, and concise video. I have actually been spending a lot of time trying to put together all the bits and pieces of what you managed to put into this fantastic video for a project of mine I shall be undertaking soon. Thank you for the time you put into collecting, and presenting all the benchmarks.

You have a new subscriber.

One advantage of LVM over ZFS though, is that you can share it across hosts. If you have a cluster using shared iSCSI, FC or SAS storage (where every host sees the same disk) you can put LVM on that disk (on the first host, use vgscan on the rest), add it as shared LVM in the GUI and all other hosts see the same volume group. Allocate VM's out of that group, and it's easy and quick to do live migrations. ZFS cannot do this.

Great video.
It is worth mentioning that it is possible to use the same ZFS pool to store all kinds of data (vdisks, backups, isos etc.). The user may create 2 datasets, and assign the first dataset as zfs storage and the second one as a directory.

You are a smart Cooke. Thank you, this info is very helpful.

[nalle]

Thanks for a great video. I found ZFS to be the best way to go.

[MHMVRCK]

Thank you for these videos. Very clear and answers the questions that come up as I'm listening. Satisfying!

[andymok]

Thanks, very useful info in this video.

I’ve been trying to learn Proxmox the past couple days and this was SUPER helpful. Thanks a bunch man. Strait to the point and you explain your opinions on the facts presented.

[RetiredRhetoricalWarhorse]

I am getting to the point of realization how much Proxmox is not anywhere near ready to be competing with Vmware.
The way administration works, the absolutely bad documentation and all the resources online are just so jank...

Too bad. I'm considering even aborting switching my homelab over. I see no benefits even to just running the current ESXi without patches indefinitely.

Ceph RADOS is definitely the way to go, I hope that the performance for BTRFS is improved in the future, I do not really care for RAID5 or 6 and prefer 10, 1 or none generally anyway. BTRFS send and receive is a killer feature. I prefer that BTRFS is licensed and in kernel, this make booting and recovery senarios based on BTRFS potentially better with some work on proxmox side.

cross fingers for BTRFS.

[AdrianuX]

5:00..
After many years, the BTRFS project is still considered unstable.
Despite this, Synology uses BTRFS in its commercial products.

[gregoryfricker]

This was an excellent video. May the algorithm bless you.

[VladyslavKudlai]

Hello dear EW, please can you again review Proxmox 8 with ZFS vs BTRFS performance?
