its local storage, but I can write to that local storage an order of magnitude quicker unless something is horribly misconfigured somewhere. To rule that out - I could try a backup restore to another node to see what speed that writes at - that should be coming in from the network at close to...

I recently set up three nodes running a fairly small VM which consists of 3 disks 25/4/25 Gb so 54Gb in total. Migration of that VM from one node to another tops out at 120 Megabit/s. You can quite clearly see the limitation on the IO graphs. I can quite happily get 950 Megabits between...

For some historical reason some of our VM's have kernel and init ram files. We specify these using the args shown at the bottom. I had putthe files into a network share that has been added to the proxmox host via cifs. Initially I put these files [vmlinuz-2.4.21-144-smp4G] into...

That code does pretty much what you'd expect - which looks fine to me. There are 4 containers in total and 1 vm. of the 4 their are two MariaDB clusters a primary and secondary. To put in perspective the busy workload is a central till journal that 350 retail shops report back to - so anything...

I doubt it- its an ultrawide bandwidth 8 SSD arrangement. That and cloning doesn't affect any other containers only the one the snapshot is from and it does it consistently. I have found a few other similar issues which relates to snapshotting and ZFS. Which could be the actual problem. But...

indeed the clone isn't linked. I don't know if this problem occurs on VM's or is specific to containers. Really the problem is squarely down to something that the clone / backup causes to interfere with MariaDB. By the time I realise there is a problem and mysql connections are stacked up I...

Using the UI, select the container, go to snapshots and then create snapshot. This is pretty quick no disruption to anything. Next right click on the still running container then click clone. You cannot clone a running container but you can clone from a previous snapshot. Do this and it...

I've asked a similar question but didn't get any response. I have a container with a large 250Gb busy database. Its Ubuntu 22.04 fully up to date and running latest MariaDB 10.6. Every 20 mins there are many commits to that database totalling a few GB per day. If I create a snapshot of that...

No response - since I wrote this I can confirm that cloning a running container from an earlier snapshot DOES interfere with the running container. I tried it again on a test and sure enough same again. I haven't done it since with the live one and no problems.

I created a small container running 22.04 and MariaDB and run a small database of about 250G in size. The database is busy and every 20 mins a couple of million rows gets fired into it from 8 threads. I created a snapshot of the container earlier and then proceeded to create a clone of the...

Ok, here is the sillyness, that I have figured out but I am still a bit confused. I am working remotely via VPN which goes via an intermediate network which is the 80 subnet (the real one). I am trying to get some of those servers into proxmox which is why I created the 80 subnet vmbr1. So...

I have 3 nodes in a cluster all running on a 192.168.6 subnet with a gateway of 6.4 and that all works fine, my containers can get a real IP via DHCP. I wanted to have a second subnet. 192.168.80. I tried this on my nested proxmox cluster and that all worked fine. When I add 80 subnet to my...

The scenario is that I have a NAT on node 1 using 192.168.1.64/24 thats because the VM's I imported to it are expecting a gateway of 64. That all works perfectly well. I then set up nodes 2 and 3 but not the NAT because I obviously can only have a single gateway of 64. So if I break my first...

Where is the discard option? What does it do and can I apply it retrospectively? Thanks.

I scrapped that installation and created one with slightly larger drives and enabled thin provisioning and it all worked well and disk space was much more modest. I am still in the dark on best practices with this, ZFS is new to me and I don't trust it, and I don't know what the performance and...

I think "allow thin provisioning" was not checked. The imported images I have are RAW format and fixed at 25Gb even though I don't think they are using much of that. So I hope there is a way I can get better efficiency.

All, hopefully a quick question, I am looking at using pve in HA and I am still playing at it at the moment. I have setup 3 VM's on a 128Gb* disk and I have joined two other nodes to that cluster. I configured replication and 2 of the VM's went fine but the final "fat" one fails at the...

The args were actually set to: -append 'root=/dev/vda ro console=tty1 console=ttyS0,115200 2' Once I saved the file I had edited but not saved to -append 'root=/dev/vda ro vdso=0 showopts vga=normal console=tty1 console=ttyS0,115200 3' This now boots and everything appears to be working...

I need to create a node with 3 servers, a DNS/DHCP an LDAP server and a WarehouseManagementSystem server. The LDAP is required for authentication into the other two. I started with the original KVM XML files and tried to match as closely as possible the settings for proxmox. A slight curveball...
