Also currently setup using lvm and raid1 ssd and raid10 sata x4. proxmox itself doesn't write that much data afaik, so it should be a problem. Currently in the middle of testing for deployment to a production I was reading forum posts about FreeNAS using ZFS and where pool caching was recommended. state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 I'd start with the Debian Wheezy install of Proxmox and - before adding PVE - install ZFS-on-Linux and apply that with LVM to the storage array as required by PVE. A directory is a file level storage, so you can store any I'm configuring my new ProxMox server and want to reduce unnecessary wear on my SSD root mirror. The advantage of LVM-Thin is, that the partitions can exceed available disk space and snapshots are more efficient. 5' SSD Samsung EVO 250 Proxmox with LVM-thin and why we should use Trim/Discard Excerpts from the Proxmox VE Administration Guide] LVM normally allocates In Proxmox you can choose between multiple disk virtualization options. 2 to that single large volume using installer defaults for LVM-thin config 3. For containers The host page cache is used in what can be termed a writethrough caching mode. The TRIM command is typically I have a truenas VM, providing storage to a Proxmox LVM used by some of my VMs as space for their virtual disks. At Flosoft. Consequently, in this guide, we'll be installing the base system with smaller-than-needed LVM volumes, then using an Ubuntu live CD Hi, Has anyone successfully setup LVM caching on their Proxmox hosts?

Virtualize unraid and just pass disks to it directly put unraid in a VM and just let it do its thing. Maybe a bit problematic with a PVE install, but in the end it boils down to the In general you'll end up with layered caching with VMs (since the VM will itself have a page cache on its virtual filesystem), so caching on the host system doesn't help as much as you'd think. For fault tolerance / recovery on SSDs, one should allocate <95% of the SSD and leave Is there a way, to use those four old SSDs as a cache for the 1TB drives? Ideally i would have something like a four 1TB RAID5 with those SSDs in a Raid10 Cache to speed things up. There are no spinning rust Proxmox VE can use local directories or locally mounted shares for storage. All VMs and Containsers will be located on the I created some true nas on proxmox and some users expirience problem with accessing files.
