* Support parallel build trees (VPATH builds)Turbo Fredriksson2015-07-1714-56/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake.

Since ZoL relies on the kernel asynchronously calling the shrinker to actually reap memory, the shrinker wakes up arc_reclaim_waiters_cv every time it runs. The arc_adapt_thread() function no longer calls arc_do_user_evicts() since the newly-added arc_user_evicts_thread() calls it periodically. Notable conflicting ZoL commits which conflicted with this patch or whose effects are either duplicated or un-done by this patch: 302f753 - Integrate ARC more tightly with Linux 39e055c - Adjust arc_p based on "bytes" in arc_shrink f521ce1 - Allow "arc_p" to drop to zero or grow to "arc_c" 77765b5 - Remove "arc_meta_used" from arc_adjust calculation 94520ca - Prune metadata from ghost lists in arc_adjust_meta Trace support for multilist_insert() and multilist_remove() has been added and produces the following output: fio-12498 [077] .... 112936.448324: zfs_multilist__insert: ml { offset 240 numsublists 80 sublistidx 63 } fio-12498 [077] .... 112936.448347: zfs_multilist__remove: ml { offset 240 numsublists 80 sublistidx 29 } The following arcstats have been removed: recycle_miss - Used by arcstat.py and arc_summary.py, both of which have been updated appropriately. l2_writes_hdr_miss The following arcstats have been added: evict_not_enough - Number of times arc_evict_state() was unable to evict enough buffers to reach its target amount. evict_l2_skip - Number of times arc_evict_hdr() skipped eviction because it was being written to the l2arc. l2_writes_lock_retry - Replaces l2_writes_hdr_miss. Number of times l2arc_write_done() failed to acquire hash_lock (and re-tries). arc_meta_min - Shows the value of the zfs_arc_meta_min module parameter (see below). The "index" column of the "dbuf" kstat has been removed since it doesn't have a direct analog in the new multilist scheme. Additional multilist- related stats could be added in the future but would likely require extensions to the mulilist API. The following module parameters have been added: zfs_arc_evict_batch_limit - Number of ARC headers to free per sub-list before moving on to the next sub-list. zfs_arc_meta_min - Enforce a floor on the amount of metadata in the ARC. zfs_arc_num_sublists_per_state - Number of multilist sub-lists per ARC state. zfs_arc_overflow_shift - Controls amount by which the ARC must exceed the target size to be considered "overflowing".

| | | | | | | | | | | | | | | | | | | | | | This commit updates the copyright boilerplate within the ZED subtree. The instructions for appending a contributor copyright line have been removed. Manually maintaining copyright notices in this manner is error-prone, imprecise at a file-scope granularity, and oftentimes inaccurate. These lines can become a pernicious source of merge conflicts. A commit log is better suited to maintaining this information. Consequently, a line has been added to the boilerplate to refer to the git commit log for authoritative copyright attribution. To account for the scenario where a file may become separated from the codebase and commit history (i.e., it is copied somewhere else), a line has been added to identify the file's origin. http://softwarefreedom.org/resources/2012/ManagingCopyrightInformation.html Signed-off-by: Chris Dunlap <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #3384

Volumes, like filesystems, are limited by the zfs_max_recordsize=1M module option. * By default the maximum record size is limited to 1M by the module option zfs_max_recordsize. This value may be safely increased up to 16M which is the largest block size supported by the on-disk format. At the moment, 1M blocks clearly offer a significant performance improvement but the benefits of going beyond this for the majority of workloads are less clear. * The illumos version of this patch increased DMU_MAX_ACCESS to 32M. This was determined not to be large enough when using 16M blocks because the zfs_make_xattrdir() function will fail (EFBIG) when assigning a TX. This was immediately observed under Linux because all newly created files must have a security xattr created and that was failing. Therefore, we've set DMU_MAX_ACCESS to 64M. * On 32-bit platforms a hard limit of 1M is set for blocks due to the limited virtual address space. We should be able to relax this one the ABD patches are merged. Ported-by: Brian Behlendorf <[email protected]> Closes #354

* Combine data-notify.sh with io-notify.shChris Dunlap2015-04-272-51/+16
| | | | | | | | | | | | | | | | | | The data-notify.sh ZEDLET serves a very similar purpose to io-notify.sh, namely, to generate a notification in response to a particular error event. Initially, data-notify.sh was separated from io-notify.sh since the "data" zevent does not (as I understand it) pertain to a specific vdev device. This stands in contrast to the "checksum" and "io" zevents (both handled by io-notify.sh) that can be attributed to a specific vdev. At the time, it seemed simpler to handle these two cases in separate scripts. This commit adds support for the "data" zevent to io-notify.sh, and symlinks io-notify.sh to data-notify.sh. It also adds the counts for vdev_read_errors, vdev_write_errors, and vdev_cksum_errors to the notification message. Signed-off-by: Chris Dunlap <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | This commit adds the zed_notify_pushbullet() function and hooks it into zed_notify(), thereby integrating it with the existing "notify" ZEDLETs. This enables ZED to push notifications to your desktop computer and/or mobile device(s). It is configured with the ZED_PUSHBULLET_ACCESS_TOKEN and ZED_PUSHBULLET_CHANNEL_TAG variables in zed.rc. https://www.pushbullet.com/ The Makefile install-data-local target has been replaced with install-data-hook. With the "-local" target, there is no particular guarantee of execution order. But with the zed.rc now potentially containing sensitive information (i.e., the Pushbullet access token), the recommended permissions have changed to 0600. The "-hook" target is always executed after the main rule's work is done; thus, the chmod will always take place after the zed.rc file has been installed. https://www.gnu.org/software/automake/manual/automake.html#Extending Signed-off-by: Chris Dunlap <[email protected]>
* Replace "email" ZEDLETs with "notify" ZEDLETsChris Dunlap2015-04-2715-258/+311
| | | | | | | | | | | | | | | | | | | | | | | | | Several ZEDLETs already exist for sending email in reponse to a particular zevent. While email is ubiquitous, alternative methods may be better suited for some configurations. Instead of duplicating the "email" ZEDLETs for every future notification method, it is preferable to abstract the notification method into a function. This has the added benefit of reducing the amount of code duplicated between ZEDLETs, and allowing related bugs to be fixed in a single location. This commit replaces the existing "email" ZEDLETs with corresponding "notify" ZEDLETs. In addition, the ZEDLET code for sending an email message has been moved into the zed_notify_email() function. And this zed_notify_email() has been added to a generic zed_notify() function for sending notifications via all available methods that have been configured. This commit also changes a couple of related zed.rc variables. ZED_EMAIL_INTERVAL_SECS is changed to ZED_NOTIFY_INTERVAL_SECS, and ZED_EMAIL_VERBOSE is changed to ZED_NOTIFY_VERBOSE. Note that ZED_EMAIL remains unchanged as its use is solely for the email notification method. Signed-off-by: Chris Dunlap <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit factors out several common ZEDLET code blocks into zed-functions.sh.

| | | | | | | | | | | | | | | | | | The "zpool status" output shows the full pathname for file-type vdevs, but only the basename component for disk-type vdevs. In commit bee6665, the "basename" command was dropped from altering the vdev name used when searching the "zpool status" output. Consequently, hot-disk sparing for disk vdevs broke since "zpool status" output was now being searched for the full pathname to the disk vdev. Parsing the "zpool status" output in this manner is rather brittle. It would be preferable to search for the vdev based on its guid. But until that happens, this commit adds back the "basename" command to fix the vdev name breakage.

| | | | | | | | | | | | Make the 'zpool import' command honor the overlay property to allow filesystems to be mounted on a non-empty directory. As it stands now this property is only checked by the 'zfs mount' command. Move the check into 'zfs_mount()` in libzpool so the property is honored for all callers.

* Check all vdev labels in 'zpool import'Brian Behlendorf2015-03-252-2/+2
| | | | | | | | | | | | | | | | | | When using 'zpool import' to scan for available pools prefer vdev names which reference vdevs with more valid labels. There should be two labels at the start of the device and two labels at the end of the device. If labels are missing then the device has been damaged or is in some other way incomplete. Preferring names with fully intact labels helps weed out bad paths and improves the likelihood of being able to import the pool. This behavior only applies when scanning /dev/ for valid pools. If a cache file exists the pools described by the cache file will be used.

* Cleanup _zed_event_add_nvpair()Chris Dunlap2015-01-301-232/+263
| | | | | | | | | | | | | | | | | | When _zed_event_add_var() was updated to be the common routine for adding zedlet environment variables, an additional snprintf() was added to the processing of each nvpair. This commit changes _zed_event_add_nvpair() to directly call _zed_event_add_var() for nvpair non-array types, thereby removing a superfluous call to snprintf(). For consistency, the helper functions for converting nvpair array types are similarly adjusted to add variables. The _zed_event_value_is_hex() and _zed_event_add_var() functions have been moved up in the file since forward declarations are not used, but no changes have been made to these functions.

* Protect against adding duplicate strings in ZEDChris Dunlap2015-01-304-151/+243
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The zed_strings container stores strings in an AVL, but does not check for duplicate strings being added. Within the AVL, strings are indexed by the string value itself. avl_add() requires the node being added must not already exist in the tree, and will assert() if this is not the case. This should not cause problems in practice. ZED uses this container in two places. In zed_conf.c, it is used to store the names of enabled zedlets as zed scans the zedlet directory listing; duplicate entries cannot occur here since duplicate names cannot occur within a directory. In zed_event.c, it is used to store the environment variables (as "NAME=VALUE" strings) that will be passed to zedlets; duplicate strings here should never happen unless there is a bug resulting in a duplicate nvpair or environment variable. This commit protects against adding a duplicate to a zed_strings container by first checking for the string being added, and removing the previous entry should one exist. This implements a "last one wins" policy. This commit also changes the prototype for zed_strings_add() to allow the string key (by which it is indexed in the AVL) to differ from the string value. By adding zedlet environment variables using the variable name as the key, multiple adds for the same variable name will result in only the last value being stored. Finally, this commit routes all additions of zedlet environment variables through the updated _zed_event_add_var(). This ensures all zedlet environment variable names are properly converted.

* Refactor arc_summary to simplify -p processingKyle Blatter2015-01-281-23/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The -p option is used to specify a specific page of output to be displayed. If omitted, all output pages would be displayed. arc_summary, as it stood, had really kludgy processing code for processing the -p option. It relied on a try-except block which was treated as an if statement and in normal operation would fail any time a user didn't specify the -p option on the command line. When the exception was thrown, the script would then display all output pages. This happened whether the -p option was omitted or malformed. Thus, in the principle use case, an exception would be raised in order to run the script as desired. The same except code would be called regardless of the exception, however, and malformed -p arguments would also cause the script to execute. Additionally, this required the function which handles the case where all output pages were to be displayed, _call_all, to be potentially called from several locations within main. This commit refactors the option processing code to simplify it and make it easier to catch runtime errors in the script. This is done by specializing the try-except block to only have an exception when the -p argument is malformed. When the -p option is correctly selected by the user, it calls a function in the unSub array directly, which will only display one page of output. Finally in the context of this refactoring the page breaks have been removed. Pages seem to have been added into the output in the FreeNAS version of the script. This patch removes pages from the output to more closely resemble the freebsd version of the script.

* Add arc_summary.py from FreeNAScburroughs2015-01-282-0/+1378
| | | | | | | | | | | | | | | | | | | | | | | | | | The arc_summary script is a useful utility for administrators on other ZFS platforms. It provides a quick and easy way to get a high level view of the current ARC state. Historically this was a perl script but it was rewritten in python for FreeNAS. We've decided to adopt the python version instead of the perl version for a few reasons. 1) ZoL has no existing perl dependencies, but it does have a python dependency for scripts such as arcstat.py and dbufstat.py. Using python for arc_summary.py helps us minimize dependencies. 2) Most major Linux distributions already depend heavily on python for their core infrastructure. This means it's very likely to be available even very early in the boot process.
