* zpool import -d to specify device pathChunwei Chen2018-01-261-12/+18
| | | | | | | | | | | | | | | | | When we know which devices have the pool we are looking for, sometime it's better if we can directly pass those device paths to zpool import instead of letting it to search through all unrelated stuff, which might take a lot of time if you have hundreds of disks. This patch allows option -d <dev_path> to zpool import. You can have multiple pairs of -d <dev_path>, and zpool import will only search through those devices. For example: zpool import -d /dev/sda -d /dev/sdb Reviewed-by: Tony Hutter <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Chunwei Chen <[email protected]> Closes #7077

* Remove vn_rename and vn_remove dependencyBrian Behlendorf2017-10-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Native Encryption for ZFS on LinuxTom Caputi2017-08-142-11/+403
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

When enabled a new thread writes uberblocks to the last slot in each label, at a set frequency, to indicate to other hosts the pool is actively imported. These uberblocks are the last synced uberblock with an updated timestamp. Property defaults to off. During tryimport, find the "best" uberblock (newest txg and timestamp) repeatedly, checking for change in the found uberblock. Include the results of the activity test in the config returned by tryimport. These results are reported to user in "zpool import". 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.

* 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.

* More ashift improvementsLOLi2017-05-031-20/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix nfs snapdir automountChunwei Chen2017-03-081-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | The current implementation for allowing nfs to access snapdir is very buggy. It uses a special fh for snapdirs, such that the next time nfsd does fh_to_dentry, it actually returns the root inode inside the snapshot. So nfsd never knows it cross a mountpoint. The problem is that nfsd will not hold a reference on the vfsmount of the snapshot. This cause auto unmounter to unmount the snapshot even though nfs is still holding dentries in it. To fix this, we return the inode for the snapdirs themselves. However, we also trigger automount upon fh_to_dentry, and return ESTALE so nfsd will revalidate and see the mountpoint and do crossmnt. Because nfsd will now be aware that these are different filesystems users must add crossmnt to their export options to access snapshot directories.

If so, do not dump it. Make a similar check when dumping Uberblocks for zdb -lu. Check whether a label already dumped contains an identical Uberblock. If so, do not dump the Uberblock. When dumping a configuration or Uberblock, state which labels it is found in (0-3), for example: labels = 1 2 3 Detecting redundant uberblocks or configurations is accomplished by calculating checksums of the uberblocks and the packed nvlists containing the configuration. If there is nothing unique to be dumped for a label (ie the configuration and uberblocks have checksums matching those already dumped) print nothing for that label. With additional l's or u's, increase verbosity as follows: -l Dump each unique configuration only once. Indicate which labels it appears in. -ll In addition, dump label space usage stats. -lll Dump every configuration, unique or not. -u Dump each unique, valid, uberblock only once. Indicate which labels it appears in. -uu In addition, state which slots are invalid. -uuu Dump every uberblock, unique or not. -uuuu Dump the uberblock blockpointer (used to be -uuu) Make exit values conform to the manual page. Failing to unpack a configuration nvlist is considered an error, as well as failing to open or read from the device. Add three tests, zdb_00{3,4,5}_pos to verify the above functionality.
