Why doesn't ZFS have user or group quotas?
ZFS FAQ at OpenSolaris.orgZFS file systems can be used as logical administrative control points, which allow you to view usage, manage properties, perform backups, take snapshots, and so on. For home directory servers, the ZFS model enables you to easily set up one file system per user. ZFS quotas are intentionally not associated with a particular user because file systems are points of administrative control.
Related QuestionsWhy doesn't ZFS have an fsck-like utility?
ZFS FAQ at OpenSolaris.orgVerify file system integrity - Many times, administrators simply want to make sure that there is no on-disk corruption within their file systems. With most file systems, this involves running fsck while the file system is offline. This can be time consuming and expensive. Instead, ZFS provides the ability to 'scrub' all data within a pool while the system is live, finding and repairing any bad data in the process. There are future plans to enhance this to enable background scrubbing.

Related QuestionsWhat does ZFS stand for?
ZFS FAQ at OpenSolaris.orgOriginally, ZFS was an acronym for "Zettabyte File System." The largest SI prefix we liked was 'zetta' ('yotta' was out of the question). Since ZFS is a 128-bit file system, the name was a reference to the fact that ZFS can store 256 quadrillion zettabytes (where each ZB is 270 bytes). Over time, ZFS gained a lot more features besides 128-bit capacity, such as rock-solid data integrity, easy administration, and a simplified model for managing your data.
Related QuestionsWhy does ZFS have 128-bit capacity?
ZFS FAQ at OpenSolaris.orgFile systems have proven to have a much longer lifetime than most traditional pieces of software, due in part to the fact that the on-disk format is extremely difficult to change. Given the fact that UFS has lasted in its current form (mostly) for nearly 20 years, it's not unreasonable to expect ZFS to last at least 30 years into the future. At this point, Moore's law starts to kick in for storage, and we start to predict that we'll be storing more than 64 bits of data in a single filesystem.
Related QuestionsWhat limits does ZFS have?
ZFS FAQ at OpenSolaris.orgThe limitations of ZFS are designed to be so large that they will never be encountered in any practical operation. ZFS can store 16 Exabytes in each storage pool, file system, file, or file attribute. ZFS can store billions of names: files or directories in a directory, file systems in a file system, or snapshots of a file system. ZFS can store trillions of items: files in a file system, file systems, volumes, or snapshots in a pool.
Related QuestionsWhat can I do if ZFS panics on every boot?
ZFS FAQ at OpenSolaris.orgZFS is designed to survive arbitrary hardware failures through the use of redundancy (mirroring or RAID-Z). Unfortunately, certain failures in non-replicated configurations can cause ZFS to panic when trying to load the pool. This is a bug, and will be fixed in the near future (along with several other nifty features, such as background scrubbing).
Related QuestionsCan devices be removed from a ZFS pool?
ZFS FAQ at OpenSolaris.orgYou can remove a device from a mirrored ZFS configuration by using the zpool detach command. Removal of a top-level vdev, such as an entire RAID-Z group or a disk in an unmirrored configuration, is not currently supported. This feature is planned for a future release.
Related QuestionsCan I split a mirrored ZFS configuration?
ZFS FAQ at OpenSolaris.orgCurrently, ZFS does not support the ability to split a mirrored configuration for cloning or backup purposes. The best method for cloning and backups is to use ZFS clone and snapshot features. For information about using ZFS clone and snapshot features, see the ZFS Admin Guide. See RFE 6421958 to recursively send snapshots that will improve the replication process across systems.
Related QuestionsIs ZFS supported in a clustered environment?
ZFS FAQ at OpenSolaris.orgSunCluster 3.2 supports a local ZFS file system as highly available (HA) in the Solaris 10 11/06 release. This support allows for live failover between systems, with automatic import of pools between systems. If you use SunCluster 3.2 to configure a local ZFS file system as highly available, review the following caution: Do not add a configured quorum device to a ZFS storage pool.
