ZFS RAID arrays can encounter various issues, from degraded pools to failed disks. Here's how to address some of the most common problems: Degraded Pool:If a pool is degraded, use thezpool statuscommand to identify the problematic disk. Replace the faulty disk withzpool replace. How to execu...
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 ...
上边这个例子创建了14个磁盘的RAID-Z , 这14个盘被分成了两组,但下边这句话有点不大明白: 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...
Storing Multiple Copies of ZFS User Data Solaris Express Community Edition, build 61: As a reliability feature, ZFS file system metadata is automatically stored multiple times across different disks, if possible. This feature is known as ditto blocks. In this Solaris release, you can specify that...

RAID-Z configurations with single-digit groupings of disks should perform better.(我的理解为:RAIDZ的配置使用单个的整颗硬盘作为磁盘组执行效率会更好,意思就是不要使用分区 ,使用整个硬盘) 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...
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 ...
Like RAID5, this uses a variable width strip for parity. Allows one to get the most capacity out of a bunch of disks with parity checking with a sacrifice to some performance. Allows a single disk failure without losing data. Example, creating a 4 VDEV RAIDZ: ...
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: ...
