What are the advantages of replicating a ZFS file system?
The advantage of replicating a ZFS file system is that you can re-create a file system on a storage pool on another system, and specify different levels of configuration for the newly created pool, such as RAID-Z, but with identical file system data.
What happens if ZFS encounters a checksum error?
A mirror configuration of two disks is undoubtedly redundant, so (according to that paragraph) it is no data corruption error if ZFS encounters a checksum error on one of the disks (at the ZFS checksum level, not the hardware level).
Why are there so many errors on Solaris ZFS?
A small number of I/O errors might indicate a temporary outage, while a large number might indicate a permanent problem with the device. These errors do not necessarily correspond to data corruption as interpreted by applications.
What does a data corruption error in ZFS mean?
ZFS maintains a persistent log of all data errors associated with a pool. […] Data corruption errors are always fatal. Their presence indicates that at least one application experienced an I/O error due to corrupt data within the pool.
What does ZFS send and receive commands do?
Using the zfs send and zfs receive commands to replicate a ZFS file system enables you to re-create a file system on a storage pool on another system, and specify different levels of configuration for the newly created pool, such as RAID-Z, but with identical file system data.
When to use ZFS snapshots and rolling back?
File system snapshots and rolling back snapshots– Use the zfs snapshotand zfs rollbackcommands if you want to easily create a copy of a file system and revert to a previous file system version, if necessary. For example, to restore a file or files from a previous version of a file system, you could use this solution.
Is there a way to save ZFS files?
You can save incremental changes between snapshots, but you cannot restore files individually. You must restore the entire file system snapshot. These commands do not provide a complete backup solution for saving your ZFS data. Remote replication– Use the zfs sendand zfs receivecommands to copy a file system from one system to another system.
