* Relax MBR partition scanning requirementBrian Behlendorf2016-03-101-21/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When checking a whole disk to see if it can be safely added to the pool a variety of checks are done. One of those checks is to attempt to determine the partition information and scan all the partitions for existing filesystems. Since ZoL contains a EFI library this partition scanning is easy to do for GPT partitioned disks. However, for non-GPT partitioned disks (MBR/EBR) things are a bit harder. The lack of a convenient library means non-GPT partitioned disks will not have all their partitions checked. For this reason, the default behavior was to require the force option. For example: invalid vdev specification use '-f' to override the following errors: /dev/vdb does not contain an GPT label but it may contain partition information in the MBR. However in practice requiring the force option for this case is counter-intuitively less safe. The reason is because only the first error is returned. By passing the force option it will suppress this first warning and potentially others you were not aware of. Therefore this patch inverts the default behavior for non-GPT formated disks (unformatted, MBR/EBR, etc). If no GPT table is detected and there is no file system detected on the provided block device. Then it will be assumed that block device is safe to use. Longer term it would be nice to see MBR/EBR scanning added to the utilities. This should be fairly straight forward to do. However these days it's somewhat less critical because Linux defaults to GPT partition tables for devices 2TB or larger. Signed-off-by: Brian Behlendorf <[email protected]> Closes #2660 Closes #2274
* Require libblkidBrian Behlendorf2016-03-092-12/+9
| | | | | | | | | | | | | | | | | | | | | | Historically libblkid support was detected as part of configure and optionally enabled. This was done because at the time support for detecting ZFS pool vdevs had just be added to libblkid and those updated packages were not yet part of many distributions. This is no longer the case and any reasonably current distribution will ship a version of libblkid which can detect ZFS pool vdevs. This patch makes libblkid mandatory at build time and libblkid the preferred method of scanning for ZFS pools. For distributions which include a modern version of libblkid there is no change in behavior. Explicitly scanning the default search paths is still supported and can be enabled with the '-s' command line option. Additionally making libblkid mandatory means that the 'zpool create' command can reliably detect if a specified device has an existing non-ZFS filesystem (ext4, xfs) and print a warning.

* Ensure zed _finish_daemonize() leaves fds 0-2 openChris Dunlap2016-03-081-1/+1
| | | | | | | | | | | | | | | In zed's _finish_daemonize(), /dev/null is open()d onto a temporary file descriptor which is then dup()d onto stdin, stdout, and stderr. But if file descriptors 0, 1, or 2 are not already open at the start of this function, then the temporary file descriptor will fall within this range and be inadvertently closed when the function cleans up. This commit adds a check to prevent inadvertently closing this (presumably temporary) file descriptor when it shouldn't.

* Change full path subcommand flag from -p to -PBrian Behlendorf2016-02-261-25/+25
| | | | | | | | | | | Commit d2f3e29 introduced the -p option which outputs full paths for vdevs to multiple zpool subcommands. When this was merged there was no conflict for this flag letter. However it's certain there will be a conflict with the -p (parsable) flag used by other subcommands. Therefore, -p is being changed to -P to avoid this.

* Add -gLp to zpool subcommands for alt vdev namesRichard Yao2016-02-251-73/+169
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following options have been added to the zpool add, iostat, list, status, and split subcommands. The default behavior was not modified, from zfs(8). -g Display vdev GUIDs instead of the normal short device names. These GUIDs can be used in-place of device names for the zpool detach/off‐ line/remove/replace commands. -L Display real paths for vdevs resolving all symbolic links. This can be used to lookup the current block device name regardless of the /dev/disk/ path used to open it. -p Display full paths for vdevs instead of only the last component of the path. This can be used in conjunction with the -L flag. This behavior may also be enabled using the following environment variables. ZPOOL_VDEV_NAME_GUID ZPOOL_VDEV_NAME_FOLLOW_LINKS ZPOOL_VDEV_NAME_PATH This change is based on worked originally started by Richard Yao to add a -g option. Then extended by @ilovezfs to add a -L option for openzfsonosx. Those changes have been merged, re-factored, a -p option added and extended to all relevant zpool subcommands.

* mount.zfs: use getopt_long instead of getopt to guarantee permutation of argv.Christian Neukirchen2016-01-251-1/+2
| | | | | | | | | | | | | | | | mount.zfs is called by convention (and util-linux) with arguments last, i.e. % mount.zfs <dataset> <mountpoint> -o <options> This is not a problem on glibc since GNU getopt(3) will reorder the arguments. However, alternative libc such as musl libc (or glibc with $POSIXLY_CORRECT set) will not permute argv and fail to parse the -o <options>. Use getopt_long so musl will permute arguments.

Writing 0 to this proc file clears the log. $ echo 1 >/sys/module/zfs/parameters/zfs_dbgmsg_enable $ echo 0 >/proc/spl/kstat/zfs/dbgmsg $ zpool import tank $ cat /proc/spl/kstat/zfs/dbgmsg 1 0 0x01 -1 0 2492357525542 2525836565501 timestamp message 1441141408 spa=tank async request task=1 1441141408 txg 70 open pool version 5000; software version 5000/5; ... 1441141409 spa=tank async request task=32 1441141409 txg 72 import pool version 5000; software version 5000/5; ... 1441141414 command: lt-zpool import tank Note the zfs_dbgmsg() and dprintf() functions are both now mapped to the same log. As mentioned above the kernel debug log can be accessed though the /proc/spl/kstat/zfs/dbgmsg kstat. For user space consumers log messages are immediately written to stdout after applying the ZFS_DEBUG environment variable. $ ZFS_DEBUG=on ./cmd/ztest/ztest -V Signed-off-by: Brian Behlendorf <[email protected]> Signed-off-by: Ned Bass <[email protected]> Closes #3728

* Rework zed_notify_email for configurable PROG/OPTSChris Dunlap2015-07-302-11/+51
| | | | | | | | | | | | | | | | | | | | | | | This commit reworks the zed_notify_email() function to allow configuration of the mail executable and command-line arguments. ZED_EMAIL_PROG specifies the name or path of the executable responsible for sending notifications via email. This variable defaults to "mail". ZED_EMAIL_OPTS specifies command-line options passed to ZED_EMAIL_PROG. The following keyword substitutions are performed: - @ADDRESS@ is replaced with the recipient email address(es) - @SUBJECT@ is replaced with the notification subject This variable defaults to "-s '@SUBJECT@' @ADDRESS@". ZED_EMAIL_ADDR replaces ZED_EMAIL (although the latter is retained for backward compatibility). This variable can contain multiple addresses as long as they are delimited by whitespace.

* 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".
