If you want to create a raid with zfs using different disk sizes you need to use zpool create (name of your pool) raidz1 -f sdb sdc sdd the -f arqument force zfs to use different sizes example 500gb 1tb 250gb hd, From the ZFS admin guide: The devices can be individual slices on a preformatted disk, or they can be entire disks that ZFS formats as a single large slice. So yes, you could create two 1-TB partitions on those 2TB drives, use them for RAID-Z vdev and the remaining space for non-redundant storage.
1.0TB. 1.0TB + 0.5TB. 1.0TB + 0.5TB. 1.0TB + 0.5TB + 0.5TB. Then: Combine all 1.0TB partitions into a single raid-z with 7.0TB usable capacity. Combine two 0.5TB partitions into two mirrors, with 0.5TB usable each. Pool the 7.0TB raid-z with a 0.5TB mirror for.
6/19/2010 · ZFS with Different size disks? I have 3 disks, 2 3Tb and 1 6Tb that I want to use for a ZFS pool in Ubuntu 16.04. WHat is the best way to pool these? I would like to makimize use of space and have parity. I was thinking that a pool of the 6Tb drive mirrored with a vdev of the comnined 3Tb drives .
Different Disk and Partition Sizes . Next, the two disk drives needed to be formatted and partitioned. ZFS can handle physical drives and partitions on them of different sizes to form a ‘pool’, which is exactly what I needed for my target system.
ZFS – Wikipedia, ZFS – Wikipedia, That ZFS is both the filesystem and volume manager I understand. The different software raid capabilities I am also familiar with (striped, mirrored, z1-3). It is when I get to vdevs and zpools that my head starts to hurt. Especially when we are talking about different size drives .
9/10/2020 · Looking for info on combining different size drives in a vdev and using all of each of the drives space, while still maintaining parity; say a vdev of 10 4TB drives and 2 10TB drives in Z2, and having, well, some amount more than 40TB of formate usable space.
A RAID-Z group within a ZFS pool will always lock the size to the smallest disk within the pool. So, currently, you have what is essentially a RAID-Z of 3x 40GB drives. One disk worth is dedicated to parity bits, so you’ve got 2x 40GB, which is 76.29 GiB.
ZFS (old: Zettabyte file system ) combines a file system with a volume manager.It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris – including ZFS – were published under an open source license as OpenSolaris for around 5 years from 2005, before being placed under a closed source license when Oracle Corporation acquired Sun in 2009/2010.
3/19/2020 · Testing with 11.3 on a Supermicro X10SBA (J1900) with 8GB of ram. I have 4 x 250GB Seagate drives installed, 3 are the same model. I can get two of the drives to allow me to create a pool if I use the ‘suggest layout’ option but if I manually try to add the drives (again, 3 with the same model…
