* 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]>
* Cleanup ZEDLETsChris Dunlap2015-04-2711-337/+630
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit factors out several common ZEDLET code blocks into zed-functions.sh. This shortens the length of the scripts, thereby (hopefully) making them easier to understand and maintain. In addition, this commit revamps the coding style used by the scripts to be more consistent and (again, hopefully) maintainable. It now mostly follows the Google Shell Style Guide. I've tried to assimilate the following resources: Google Shell Style Guide https://google-styleguide.googlecode.com/svn/trunk/shell.xml Dash as /bin/sh https://wiki.ubuntu.com/DashAsBinSh Filenames and Pathnames in Shell: How to do it Correctly http://www.dwheeler.com/essays/filenames-in-shell.html Common shell script mistakes http://www.pixelbeat.org/programming/shell_script_mistakes.html Finally, this commit updates the exit codes used by the ZEDLETs to be more consistent with one another. All scripts run cleanly through ShellCheck <http://www.shellcheck.net/>. All scripts have been tested on bash and dash. Signed-off-by: Chris Dunlap <[email protected]>

* Fix kernel panic due to tsd_exit in ZFS_EXIT(zsb)Chunwei Chen2015-04-242-1/+2
| | | | | | | | | | | | | | | | | | | | | | The following panic would occur under certain heavy load: [ 4692.202686] Kernel panic - not syncing: thread ffff8800c4f5dd60 terminating with rrw lock ffff8800da1b9c40 held [ 4692.228053] CPU: 1 PID: 6250 Comm: mmap_deadlock Tainted: P OE 3.18.10 #7 The culprit is that ZFS_EXIT(zsb) would call tsd_exit() every time, which would purge all tsd data for the thread. However, ZFS_ENTER is designed to be reentrant, so we cannot allow ZFS_EXIT to blindly purge tsd data. Instead, we rely on the new behavior of tsd_set. When NULL is passed as the new value to tsd_set, it will automatically remove the tsd entry specified the the key for the current thread. rrw_tsd_key and zfs_allow_log_key already calls tsd_set(key, NULL) when they're done. The zfs_fsyncer_key relied on ZFS_EXIT(zsb) to call tsd_exit() to do clean up. Now we explicitly call tsd_set(key, NULL) on them.

* Support the "version" property on volumes via the zfs_prop_get_int() APITim Chase2015-04-241-0/+3
| | | | | | | | | | | | | | | | | As of this commit, volumes do not possess the version property in any existing OpenZFS implementation. The zpool upgrade code, however, uses zfs_prop_get_int() to fetch the version property of all children in a pool. The semantics of the function, however, demand that it only be used for known valid properties so it returns a garbage value for volumes. This patch causes the version of a volume to appear to callers using the zfs_prop_get_int() API to be that of the default ZPL version for the implementation. In the future, should volumes gain the property, its actual value will be used. Signed-off-by: Tim Chase <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Fixes #3313

* Fix io-spare.sh to work with disk vdevsChris Dunlap2015-04-171-1/+1
| | | | | | | | | | | | | | | | | | 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.

* Allocate zfs_znode_cache on the Linux slabTim Chase2015-04-141-2/+4
| | | | | | | | | | | | | | | | | | | The Linux slab, in general, performs better than the SPl slab in cases where a lot of objects are allocated and fragmentation is likely present. This patch fixes pathologically bad behavior in cases where the ARC is filled with mostly metadata and a user program needs to allocate and dirty enough memory which would require an insignificant amount of the ARC to be reclaimed. If zfs_znode_cache is on the SPL slab, the system may spin for a very long time trying to reclaim sufficient memory. If it is on the Linux slab, the behavior has been observed to be much more predictible; the memory is reclaimed more efficiently.

* Fix arc_adjust_meta() behaviorBrian Behlendorf2015-03-202-23/+80
| | | | | | | | | | | | | | | | | | | | | | | | The goal of this function is to evict enough meta data buffers from the ARC in order to enforce the arc_meta_limit. Achieving this is slightly more complicated than it appears because it is common for data buffers to have holds on meta data buffers. In addition, dnode meta data buffers will be held by the dnodes in the block preventing them from being freed. This means we can't simply traverse the ARC and expect to always find enough unheld meta data buffer to release. Therefore, this function has been updated to make alternating passes over the ARC releasing data buffers and then newly unheld meta data buffers. This ensures forward progress is maintained and arc_meta_used will decrease. Normally this is sufficient, but if required the ARC will call the registered prune callbacks causing dentry and inodes to be dropped from the VFS cache. This will make dnode meta data buffers available for reclaim. The number of total restarts in limited by zfs_arc_meta_adjust_restarts to prevent spinning in the rare case where all meta data is pinned.

* Restructure per-filesystem reclaimBrian Behlendorf2015-03-206-43/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally when the ARC prune callback was introduced the idea was to register a single callback for the ZPL. The ARC could invoke this call back if it needed the ZPL to drop dentries, inodes, or other cache objects which might be pinning buffers in the ARC. The ZPL would iterate over all ZFS super blocks and perform the reclaim. For the most part this design has worked well but due to limitations in 2.6.35 and earlier kernels there were some problems. This patch is designed to address those issues. 1) iterate_supers_type() is not provided by all kernels which makes it impossible to safely iterate over all zpl_fs_type filesystems in a single callback. The most straight forward and portable way to resolve this is to register a callback per-filesystem during mount. The arc_*_prune_callback() functions have always supported multiple callbacks so this is functionally a very small change. 2) Commit 050d22b removed the non-portable shrink_dcache_memory() and shrink_icache_memory() functions and didn't replace them with equivalent functionality. This meant that for Linux 3.1 and older kernels the ARC had no mechanism to drop dentries and inodes from the caches if needed. This patch adds that missing functionality by calling shrink_dcache_parent() to release dentries which may be pinning inodes. This will result in all unused cache entries being dropped which is a bit heavy handed but it's the only interface available for old kernels. 3) A zpl_drop_inode() callback is registered for kernels older than 2.6.35 which do not support the .evict_inode callback. This ensures that when the last reference on an inode is dropped it is immediately removed from the cache. If this isn't done than inode can end up on the global unused LRU with no mechanism available to ZFS to drop them. Since the ARC buffers are not dropped the hottest inodes can still be recreated without performing disk IO.

* Increase Linux pipe buffer size on 'zfs receive'Richard Yao2015-03-201-0/+43
| | | | | | | | | | | | | | | | | | | | | I noticed when reviewing documentation that it is possible for user space to use fctnl(fd, F_SETPIPE_SZ, (unsigned long) size) to change the kernel pipe buffer size on Linux to increase the pipe size up to the value specified in /proc/sys/fs/pipe-max-size. There are users using mbuffer to improve zfs recv performance when piping over the network, so it seems advantageous to integrate such functionality directly into the zfs recv tool. This avoids the addition of two buffers and two copies (one for the buffer mbuffer adds and another for the additional pipe), so it should be more efficient. This could have been made configurable and/or this could have changed the value back to the original after we were done with the file descriptor, but I do not see a strong case for doing either, so I went with a simple implementation.

* Mark zfs_inactive() with PF_FSTRANSBrian Behlendorf2015-03-101-0/+8
| | | | | | | | | | | Allowing direct reclaim to re-enter the VFS in the zfs_inactive() call path has historically been problematic for ZoL. Therefore, in order to avoid an entire class of current and future issues caused by this PF_FSTRANS is set for all zfs_inactive() callers.

* Use cached feature info in spa_add_feature_stats()Ned Bass2015-03-054-11/+51
| | | | | | | | | | | | | | | | Avoid issuing I/O to the pool when retrieving feature flags information. Trying to read the ZAPs from disk means that zpool clear would hang if the pool is suspended and recovery would require a reboot. To keep the feature stats resident in memory, we hang a cached nvlist off of the spa. It is built up from disk the first time spa_add_feature_stats() is called, and refreshed thereafter using the cached feature reference counts. spa_add_feature_stats() gets called at pool import time so we can be sure the cached nvlist will be available if the pool is later suspended.

* Replace zfs.redhat.in with zfs.lsb.in init scriptBrian Behlendorf2015-03-041-104/+73
| | | | | | | | | | | | | | | | | | | | | | | | | This commit replaces the zfs.redhat.in init script with a slightly modified version of the existing zfs.lsb.in init script. This was done to minimize the functional differences between platforms. The lsb version of the script was choosen because it's heavily tested and provides the most functionality. Changes made for RHEL systems: * Configuration: /etc/default/zfs -> /etc/sysconfig/zfs * LSB functions: /lib/lsb/init-functions -> /etc/rc.d/init.d/functions * Logging: log_begin_msg/log_end_msg -> action Features in LSB which are now in RHEL: * USE_DISK_BY_ID=0 - Use the by-id names * VERBOSE_MOUNT=0 - Verbose mounts by default * DO_OVERLAY_MOUNTS=0 - Overlay mounts by default * MOUNT_EXTRA_OPTIONS=0 - Generic extra options Existing RHEL features which were removed: * Automatically mounting FSs on ZVOLs listed in /etc/fstab Signed-off-by: Brian Behlendorf <[email protected]> Issue #3153
