How do I increase the size of ZFS filesystem?
You can add the 5 Gb space in your current size (12Gb). In above command you can reserve the 17G space to root filesystem. You can check the new filesystem space using “zfs get quota” command.
Can you expand a ZFS pool?
Expanding storage in ZFS The heart of a ZFS storage system is the zpool —this is the most fundamental level of ZFS storage. A storage vdev can be one of five types—a single disk, mirror, RAIDz1 , RAIDz2 , or RAIDz3 . You can add more vdevs to a zpool , and you can attach more disks to a single or mirror vdev .
How does ZFS pool work?
Instead of forcing you to create virtualized volumes, ZFS aggregates devices into a storage pool. The storage pool describes the physical characteristics of the storage (device layout, data redundancy, and so on) and acts as an arbitrary data store from which file systems can be created.
Is the ZFS file system supported in Solaris 11?
−Only ZFS is supported for the system area (root file system) of Solaris 11. −The existing UFS file system can be used only for user areas. −The storage pool of the system area is called the “root pool.” Copyright 2012 -2016 FUJITSU LIMITED
Why does ZFS resilver while data is still in use?
ZFS will resilver while the data is still in use, it is a live recovery. The implication of this is that our disks are working harder than usual during this process, and this can increase the chances of a second drive failure.
What are some cool things that ZFS can do?
This means that ZFS can do some cool things like snapshots that a normal filesystem like NTFS could not. A snapshot can be thought of like it sounds, a photograph of how something was at a point in time. How a COW filesystem works, however, has some important implications that we need to discuss.
What does it mean to have ZFS on your hard drive?
What that means is ZFS directly controls not only how the bits and blocks of your files are stored on your hard drives, but it also controls how your hard drives are logically arranged for the purposes of RAID and redundancy. ZFS is also classified as a copy-on-write or COW filesystem.
