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.
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
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.
This article describes available ZFS versions, features of each version, and the Solaris release that provides the ZFS version and feature
Most ZFS errors I've experienced generally fall into one of three categories. missing devices, damaged devices and data corruption.
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)
In ZFS, I/Os are scheduled similarly to how jobs are scheduled on CPUs.
When disks are added to an existing mirrored or RAID Z pool, the ZFS is resilvered to redistribute the data.
