Best RAID for 6 Disks: Compare RAID 0, 5, 6, 10, 50 & 60 for Performance & Redundancy RAID 5 vs RAID 0+1: Key Differences Explained RAID Level 4: What Is RAID 4, How It Works ZFS RAID with Different Size Drives
For optimal performance, the pool sector size should be greater than or equal to the sector size of the underlying disks. Since the property cannot be changed after pool creation, if in a given pool, you ever want to use drives that report 4KiB sectors, you must set ashift=12 at pool ...
Another important factor when using any RAIDZ level is how ZVOL datasets, which are used for VM disks, behave. For each data block the pool needs parity data which is at least the size of the minimum block size defined by theashiftvalue of the pool. With an ashift of 12 the block siz...
By default zfsutils-linux will come with a crontab entry that will scrub the disks. $cat /etc/cron.d/zfsutils-linux PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin#Scrub the second Sunday of every month. 24 0 8-14 * * root [ $(date +\%w) -eq 0 ] &&...
when you care about your data and scale to more than one or two disks, this is probably the only reasonable approach a good idea even with pricy disks but especially with cheaper disks. (it relates to the whole "Bit Error Rate has stayed constant while arrays are getting much bigger" ...

In previous releases, ZFS was not able to replace an existing disk with another disk or attach a disk if the replacement disk was a slightly different size. In this release, you can replace an existing disk with another disk or attach a new disk that is nominally the same size provided ...

RAID-Z configurations with single-digit groupings of disks should perform better. RAID-Z具有自动修复数据的功能 当有损坏的数据块被检测到,ZFS不但能从备份中找到相同的正确的数据,而且还能自动的用正确数据修复损坏的数据。 创建ZFS存储池 1、创建一个基本的存储池,方法很简单: ...
