Repairing a Damaged ZFS Device
This article describes how to determine ZFS device failure types, clear transient errors, and replace a device.

If a device cannot be opened, it displays as UNAVAILABLE in the zpool status output.
With ZFS filesystem, RAIDZ is very popular as it gives the best tradeoff of hardware failure protection versus storage.
You can use the zfs send command to send a copy of a snapshot stream and receive the snapshot stream in another pool
If you need to adjust the size of the swap volume after installation on an active system, review the following steps. See CR 6765386 for more info
ZFS has the ability to send and receive data. This can be used to combine snapshots, create backups, or replicate data between servers
Renaming a zpool is not as intuitive as I would expect, but it is still pretty simple. However, we can accomplish this through a three step process.
The following is a simple example of creating a ZFS filesystem and using it to hold a newly-created Solaris Zone (Solaris Container)
This is a standard question for Solaris administrators who unfortunately have requirements for an older Solaris 9 kernel for a legacy application.
The ability to resume an interrupted zfs send/receive data stream which is a representation of a snapshot is now part of Oracle Solaris 11.4
Using Shadow Migration is very easy; for example, we could migrate shared ZFS and UFS file systems through NFS or even through a local file system
Setting the size of a ZFS dataset can ensure an appropriate allocation of space configuration that contains multiple volumes to service different clients
This article describes available ZFS versions, features of each version, and the Solaris release that provides the ZFS version and feature
A simple method of extract the log files from a ZFS storage Appliance to browse at leisure
ZFS uses the concept of storage pools to manage physical storage. Historically, file systems were constructed on top of a single physical device.
The aim of this article is to show how to increase the virtual storage capacity on the ZFS Storage Appliance Smulator virtual machine.
This article shows how to configure iSCSI LUNs on an ZFS Storage Appliance and integrate them to a Ubuntu Server using the command line.
A short tip on how to increate the size of swap online for a given Solaris system under zfs.
Most ZFS errors I've experienced generally fall into one of three categories. missing devices, damaged devices and data corruption.
Because ZFS uses kernel addressable memory, we need to make sure to allow enough system resources to take advantage of its capabilities
Max Bruning wrote an excellent paper on how to examine the internals of a ZFS data structure.
A ZFS owned disk may be promoted to be a quorum disk on current Sun Cluster versions
Once the drive has been physically replaced, run the 'zfs replace' command against the device to allow it to be brought back online.
ZFS is a transactional file system. For each write request, a copy is made of the specified block protected by Copy-On-Write (COW)
If the filesystem is created in the global zone and added to the local zone via zonecfg, it may be assigned to more than one zone
The difference between a snapshot and a clone is that a clone is a writable, mountable copy of the file system.
In ZFS, I/Os are scheduled similarly to how jobs are scheduled on CPUs.
ZFS filesystems automatically stripe across all top-level disk devices. (Mirrors and RAID-Z devices are considered to be top-level devices)
Similar filesystems should be grouped together in hierarchies to make management easier.
ZFS uses the concept of storage pools to manage physical storage. Historically, file systems were constructed on top of a single physical device.
When disks are added to an existing mirrored or RAID Z pool, the ZFS is resilvered to redistribute the data.
how to perform a LiveUpgrade of a Solaris system with ZFS
A simple entry on how to discover or set the size for a given ZFS dataset as occasionaly we need to increase the size of a ZFS dataset.
