In this example, we are going from a 100GB to a 200GB volume. Doing so will simply cut the end of the disk off and will cause data to lose. NOTE: This is critical nothing stops you from setting the new size to be smaller than the old size. Zfs get volsize DiskPool0/vol01 :~# zfs get volsize DiskPool0/vol01 We will see “volsize” properties for volumes only, as we can’t see the same for datasets. Zfs list -r DiskPool0 :~# zfs list -r DiskPool0 But zvols have to extend by setting the volsize property to a new size. The ZFS dataset can be grown by setting the quota and reservation properties. Please Like my post over here.In ZFS, there are two types of filesystems (datasets and zvol). PSU: Fractal ION 2+ 650WLike my post (or find it helpful)?.

It can live on the top-level dataset (which shares the pools name) or in any child dataset. 2 x WD Green 3D NAND (120GB, 2.5") - Boot drives (maybe mess around trying out the thread to put swap here too link) A zvol is a special type of dataset that provides a block device instead of a filesystem.1 x ASUS Z10PA-D8 (LGA 2011-v3, Intel C612 PCH, ATX) - Dual socket MoBo.Future changes to FreeBSD's zvol code will increase its performance. For high performance, file extents are recommended at this time. In practice, a file extent outperforms in reads/writes but this is only noticeable at 10 GB Ethernet speeds or higher. Aiming to mostly replicate the build from (with some mods, hopefully around about as good as that link) In theory, a zvol and a file extent should have identical performance.
