@Gateway IT Tutorials: do you have a tutorial on how to make ZFS over iscsi work with proxmox? I tried with the newest versions but with no luck. Even patched from the most recent source code, but it is not working with TrueNAS. Seems not to work because truenas no longer use istgt for iscsi implementation. Do you have any suggestions for me?
@@selfhosted yes, true. But in that case you have a limited number of backups) when with snaps, on ZFS at least, numbers are limitless) Backups and snaps are just different. But there is a use case for both)
Edit: looks like I was mistaken. Proxmox doesn't appear to have a built in auto snapshot features. Just ability to create manual snapshots. Only automatic backups which don't use ZFS features. Probably a worthwhile feature request to have snapshot scheduling and retention exposed to the proxmox web UI.
Thanks for your comment. There were feature requests like that on ProxMox Jira and forums, but no one implemented them. That's why I decided to make a video that describes the functionality :) If there was a gui option, what would be the point of me wasting my time to make and edit this vid?)
@@GatewayITTutorials I'm also interested in this (ZFS over iSCSI using TrueNAS). I'm even more interested in your opinion about using TrueNAS as your iSCSI server. I'm about to build one, but I see there are some alternatives (OMV, AMAHI, OpenFiler, ...) and wondered which would be the best choice for iSCSI.
@@geoffhart I am against home built iSCSI storage altogether, hyperconverged setup is better, gives you a lot more flexibility.

@@GatewayITTutorials Thanks! That's the advice I was looking for! As for "hyperconverged", from their web site they appear to be some sort of cloud service? But with all the recent activity over here in the US in 2020, I'm intentionally trying to avoid all cloud services ;). I want to be able to pack up my 4 systems (and a few RPis) and be able to setup shop on a deserted island (or my cabin up north, with 20 solar panels) and work like I'm at work :D - that's what got me looking at TrueNAS in the first place.

If you include RAM - Proxmox pauses the VM until the contents of the RAM are fully dumped. Storage only snapshot should be instant (at least on ZFS it's instant) and should not affect your VM in any way.
Hi nice work can you help me ....i am using proxmox 6.2 with 4 window n 2 linux guest...i wonder can i fix a corn job for window like i need 4 window up at 10am each day n shutdown at 7pm....
@@prashantkachhawaha3707 you can stop and start VMs with commands: qm start VMID or qm stop VMID VMID is the VM or container number inside of ProxMox. Like 100, or 1004. From here you could create two bash scripts with few lines to start and stop the required list of VMs. Then just drop those to crontab as I did with the snapshotting tool.
Did you use this to setup zfs over iscsi? github.com/TheGrandWazoo/freenas-proxmox Im about to setup TrueNAS using zfs over iscsi, and have been researching how to do so. Any tips you have would be appreciated!
Yes, this is exactly what I used. Keep in mind that you'll have to apply the patch after each update on ProxMox. So I would recommend keeping away from updates at all (on both Prox and NAS) because I witnessed too many problems :)
@@GatewayITTutorials I hope to rack the new server in the DC in the next couple of weeks. I may make a video on how to use the GitHub repo to use zfs over iscsi. Moving from NFS shared to my Proxmox cluster on a Synology NAS to a dedicated server running TrueNAS Scale and zfs over iscsi. Should be an interesting process. Thanks for the info!

Cool script! Why not just take advantage of auto backups instead through the datacenter?
Backups are different. Snaps are incremental, but backups are full every time.
So if your VM is 100GB, after 5 backups, there's 500GB of space used.
Gateway IT Tutorials you can overwrite backups instead of letting them stack up. I do love snapshots though.

Can you do a video showing ZSH over ISCSI?
Sure thing. I was planning on doing so anyway :)

How does snapshotting hourly affect services running on the host? I noticed that my nextcloud install froze up during snapshotting when including ram.
If you include RAM - Proxmox pauses the VM until the contents of the RAM are fully dumped. Storage only snapshot should be instant (at least on ZFS it's instant) and should not affect your VM in any way.
@@GatewayITTutorials You're the best thanks!: )
I can't even get zfs over iscsi to work after the script. I wasn't able to write on it.
Hi nice work can you help me ....i am using proxmox 6.2 with 4 window n 2 linux guest...i wonder can i fix a corn job for window like i need 4 window up at 10am each day n shutdown at 7pm....
It's relatively easy to do. Is it just one ProxMox host? Or multiple?
Only one host n 7 guest window n some linux...linux i need 24*7 but window i need 10am to 7pm
I used in aws cloud watch pretty help full ...i need with proxmox...thank in advance
