* Project Quota on ZFSNasf-Fan2018-02-131-0/+212
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Project quota is a new ZFS system space/object usage accounting and enforcement mechanism. Similar as user/group quota, project quota is another dimension of system quota. It bases on the new object attribute - project ID. Project ID is a numerical value to indicate to which project an object belongs. An object only can belong to one project though you (the object owner or privileged user) can change the object project ID via 'chattr -p' or 'zfs project [-s] -p' explicitly. The object also can inherit the project ID from its parent when created if the parent has the project inherit flag (that can be set via 'chattr +P' or 'zfs project -s [-p]'). By accounting the spaces/objects belong to the same project, we can know how many spaces/objects used by the project. And if we set the upper limit then we can control the spaces/objects that are consumed by such project. It is useful when multiple groups and users cooperate for the same project, or a user/group needs to participate in multiple projects. Support the following commands and functionalities: zfs set projectquota@project zfs set projectobjquota@project zfs get projectquota@project zfs get projectobjquota@project zfs get projectused@project zfs get projectobjused@project zfs projectspace zfs allow projectquota zfs allow projectobjquota zfs allow projectused zfs allow projectobjused zfs unallow projectquota zfs unallow projectobjquota zfs unallow projectused zfs unallow projectobjused chattr +/-P chattr -p project_id lsattr -p This patch also supports tree quota based on the project quota via "zfs project" commands set as following: zfs project [-d|-r] <file|directory ...> zfs project -C [-k] [-r] <file|directory ...> zfs project -c [-0] [-d|-r] [-p id] <file|directory ...> zfs project [-p id] [-r] [-s] <file|directory ...> For "df [-i] $DIR" command, if we set INHERIT (project ID) flag on the $DIR, then the proejct [obj]quota and [obj]used values for the $DIR's project ID will be shown as the total/free (avail) resource. Keep the same behavior as EXT4/XFS does.

* Fix zdb -R decompressionChunwei Chen2018-02-091-1/+3
| | | | | | | | | | | | | | | | | | | | There are some issues in the zdb -R decompression implementation. The first is that ZLE can easily decompress non-ZLE streams. So we add ZDB_NO_ZLE env to make zdb skip ZLE. The second is the random bytes appended to pabd, pbuf2 stuff. This serve no purpose at all, those bytes shouldn't be read during decompression anyway. Instead, we randomize lbuf2, so that we can make sure decompression fill exactly to lsize by bcmp lbuf and lbuf2. The last one is the condition to detect fail is wrong.

This would greatly improve performance for channel programs that just gather information, as they won't have to wait for synching context anymore. === What is implemented? This feature introduces the following: - A new command line flag in "zfs program" to specify our intention to run in open context. (The -n option) - A new flag/option within the channel program ioctl which selects the context. - Appropriate error handling whenever we try a channel program in open-context that contains zfs.sync* expressions. - Documentation for the new feature in the manual pages. === How do we handle zfs.sync functions in open context? When such a function is found by the interpreter and we are running in open context we abort the script and we spit out a descriptive runtime error. For example, given the script below ... arg = ... fs = arg["argv"][1] err = zfs.sync.destroy(fs) msg = "destroying " .. fs .. " err=" .. err return msg if we run it in open context, we will get back the following error: Channel program execution failed: [string "channel program"]:3: running functions from the zfs.sync submodule requires passing sync=TRUE to lzc_channel_program() (i.e. do not specify the "-n" command line argument) stack traceback: [C]: in function 'destroy' [string "channel program"]:3: in main chunk === What about testing? We've introduced new wrappers for all channel program tests that run each channel program as both (startard & open-context) and expect the appropriate behavior depending on the program using the zfs.sync module.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The only place vn_rename and vn_remove are used is when writing out an updated pool configuration file. By truncating the file instead of renaming and removing it we can avoid having to implement these interfaces entirely. Functionally an empty cache file is treated the same as a missing cache file. This is particularly advantageous because the Linux kernel has never provided a way to reliably implement vn_rename and vn_remove. The cachefile_004_pos.ksh test case was updated to understand that an empty cache file is the same as a missing one. The zfs-import-* systemd service files were not updated to use ConditionFileNotEmpty in place of ConditionPathExists. This means that after exporting all pools and rebooting new pools will not the scanned for on the next boot. This small change should not impact normal usage since pools are not exported as part of a normal shutdown. Documentation was updated accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change incorporates three major pieces: The first change is a keystore that manages wrapping and encryption keys for encrypted datasets. These commands mostly involve manipulating the new DSL Crypto Key ZAP Objects that live in the MOS. Each encrypted dataset has its own DSL Crypto Key that is protected with a user's key. This level of indirection allows users to change their keys without re-encrypting their entire datasets. The change implements the new subcommands "zfs load-key", "zfs unload-key" and "zfs change-key" which allow the user to manage their encryption keys and settings. In addition, several new flags and properties have been added to allow dataset creation and to make mounting and unmounting more convenient. The second piece of this patch provides the ability to encrypt, decyrpt, and authenticate protected datasets. Each object set maintains a Merkel tree of Message Authentication Codes that protect the lower layers, similarly to how checksums are maintained. This part impacts the zio layer, which handles the actual encryption and generation of MACs, as well as the ARC and DMU, which need to be able to handle encrypted buffers and protected data. The last addition is the ability to do raw, encrypted sends and receives. The idea here is to send raw encrypted and compressed data and receive it exactly as is on a backup system. This means that the dataset on the receiving system is protected using the same user key that is in use on the sending side. By doing so, datasets can be efficiently backed up to an untrusted system without fear of data being compromised.

* Add zgenhostid utility scriptOlaf Faaland2017-07-253-1/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turning the multihost property on requires that a hostid be set to allow ZFS to determine when a foreign system is attemping to import a pool. The error message instructing the user to set a hostid refers to genhostid(1). Genhostid(1) is not available on SUSE Linux. This commit adds a script modeled after genhostid(1) for those users. Zgenhostid checks for an /etc/hostid file; if it does not exist, it creates one and stores a value. If the user has provided a hostid as an argument, that value is used. Otherwise, a random hostid is generated and stored. This differs from the CENTOS 6/7 versions of genhostid, which overwrite the /etc/hostid file even though their manpages state otherwise. A man page for zgenhostid is added. The one for genhostid is in (1), but I put zgenhostid in (8) because I believe it's more appropriate. The mmp tests are modified to use zgenhostid to set the hostid instead of using the spl_hostid module parameter. zgenhostid will not replace an existing /etc/hostid file, so new mmp_clear_hostid calls are required.

Allow the user to control the period between MMP writes, and the duration of the activity test on import, via a new module parameter zfs_multihost_interval. The period is specified in milliseconds. The activity test duration is calculated from this value, and from the mmp_delay in the "best" uberblock found initially. Add a kstat interface to export statistics about Multiple Modifier Protection (MMP) updates. Include the last synced txg number, the timestamp, the delay since the last MMP update, the VDEV GUID, the VDEV label that received the last MMP update, and the VDEV path.

By default it is set to zero meaning that no MMP statistics are stored. When using ztest to generate activity, for automated tests of the MMP function, some test functions interfere with the test. For example, the pool is exported to run zdb and then imported again. Add a new ztest function, "-M", to alter ztest behavior to prevent this. Add new tests to verify the new functionality.

| | | | | | | | | | | | | | | | | | Currently, there is no way to pause a scrub. Pausing may be useful when the pool is busy with other I/O to preserve bandwidth. This patch adds the ability to pause and resume scrubbing. This is achieved by maintaining a persistent on-disk scrub state. While the state is 'paused' we do not scrub any more blocks. We do however perform regular scan housekeeping such as freeing async destroyed and deadlist blocks while paused.

* Make createtxg and guid properties publicChristian Schwarz2017-05-091-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Document the existence of `createtxg` and `guid` native properties in man pages and zfs command output. One of the great features of ZFS is incremental replication of snapshots, possibly between pools on different machines. Shell scripts are commonly used to auomate this procedure. They have to find the most recent common snapshot between both sides and then perform incremental send & recv. Currently, scripts rely on the sorting order of `zfs list`, which defaults to `createtxg`, and the assumption that snapshot names on either side do not change. By making `createtxg` and `guid` part of the public ZFS interface, scripts are enabled to use a) `createtxg` to determine the logical & temporal order of snapshots (the creation property is not an equivalent substitute since multiple snapshots may be created within one second) b) `guid` to uniquely identify a snapshot, independent of its current display name This has the potential of making scripts safer and correct.

| | | | | | | | | | | | | | | | | | | | | | | | | | This commit allow higher ashift values (up to 16) in 'zpool create' The ashift value was previously limited to 13 (8K block) in b41c990 because the limited number of uberblocks we could fit in the statically sized (128K) vdev label ring buffer could prevent the ability the safely roll back a pool to recover it. Since b02fe35 the largest uberblock size we support is 8K: this allow us to store a minimum number of 16 uberblocks in the vdev label, even with higher ashift values. Additionally change 'ashift' pool property behaviour: if set it will be used as the default hint value in subsequent vdev operations ('zpool add', 'attach' and 'replace'). A custom ashift value can still be specified from the command line, if desired. Finally, fix a bug in add-o_ashift.ksh caused by a missing variable.

* Prebaked scripts for zpool status/iostat -cTony Hutter2017-04-211-30/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the "zpool status/iostat -c" commands to only run "pre-baked" scripts from the /etc/zfs/zpool.d directory (or wherever you install to). The scripts can only be run from -c as an unprivileged user (unless the ZPOOL_SCRIPTS_AS_ROOT environment var is set by root). This was done to encourage scripts to be written is such a way that normal users can use them, and to be cautious. If your script needs to run a privileged command, consider adding the appropriate line in /etc/sudoers. See zpool(8) for an example of how to do this. The patch also allows the scripts to output custom column names. If the script outputs a line like: name=value then "name" is used for the column name, and "value" is its value. Multiple columns can be specified by outputting multiple lines. Column names and values can have spaces. If the value is empty, a dash (-) is printed instead. After all the "name=value" lines are read (if any), zpool will take the next the next line of output (if any) and print it without a column header. After that, no more lines will be processed. This can be useful for printing errors. Lastly, this patch also disables the -c option with the latency and request size histograms, since it produced awkward output and made the code harder to maintain.
