Strange... today morning it created the pool without any issue... Yes, exactly - I've made a "physical" RAID (on P440ar raid controller) and it's connected to the VM as physical device. On StarWind vSAN side - the disk was in Ready state, but previously when creating a pool on one host it ...

No need to sacrifice the environment if the reconfiguration is done to one node at a time, starting with the not synchronized one. RAID0 seems a bad idea given no redundancy. Go for RAID1. RAID6 out of HDDs is against best practices (https://www.starwindsoftware.com/best-practices/starwind-virtual-...

ZFS for production is not good due to a huge performance hit. HDDs make it even worse. Try creating a physical array out of those 6 disks. Here, some remote assistance will be great to review and help you with reconfiguration, yet it is not possible as you have a FREE license. Please discuss conver...

P440 (HBA MODE) -> Backplane -> 2x "RAW" disks used for Proxmox -> ZFS Mirror P440 (HBA MODE) -> Backplane -> 6x "RAW" disks passed through to the CVM All these are HDDs. And no, I'm not using any windows based management console for vSAN - I only use CVM GUI to manage. Where I ...

Set the parameter value to the faster client response first. If no luck, use haSyncPriority and set the value 5. You can create a physical RAID and use something like raw-device-mapping (i.e., map the VD device to CVM in Proxmox). This is not an option in this case, because I have to rebuild whole ...

ZFS is generally not recommended for virtualization workloads. Could you please let me know what those disks are and what ZFS configuration you have? Try setting replication to 5% with the script. I cannot passthrough the P440 Controller in HBA mode, because proxmox boot disks are also connected to...

Set the parameter value to the faster client response first. If no luck, use haSyncPriority and set the value 5. How is the storage connected to CVM? Are they QUEMU, RDM, or pass through devices? Changed priority to "Faster client request processing" - not helped. I cannot see an option t...

Please reduce synchronization priority to 5% . I can see that the replication is stopping due to underlying storage delays. I think it might be related to the ZFS volume you use. Could you please tell me more about the storage configuration? Where I can configure sync priority by percentage? I don'...

Please pull the logs from all nodes (Log in to the Web management interface -> Select the gear-shaped button -> Expand the VM name view -> Support Bundle). Upload them here https://www.starwindsoftware.com/support-form using 1364582 as your reference.

Done.

I've changed the drivers to VMXNET3 on all vSAN VMs - no luck. My network looks like this: pve1 vmbr25a (x.x.100.1) -> pve2 vmbr25a (x.x.100.2) pve1 vmbr25b (x.x.101.1) -> pve3 vmbr25a (x.x.101.2) pve2 vmbr25a (x.x.100.2) -> pve1 vmbr25a (x.x.100.1) pve2 vmbr25b (x.x.102.1) -> pve3 vmbr25b (x.x.102....

Hi, I've been doing some tests before I'll go fully into production, restarted all the proxmox nodes (3 node cluster), and the vSAN failed to synchronize. Currently only one vSAN appliance is working OK, but in this way I'm not having any HA. It throws below error all the time for 2 vSAN appliances:...

Hi, I'm testing Starwind VSAN Free on Proxmox 8.4.5 (3-node cluster). I've noticed, that after host restart, at least the restarted host is not connecting to its own vSAN after it'll become alive again. Most probably it's because proxmox is connecting to all iscsi sessions at the start, but before S...
