* Dump unique configurations and Uberblocks in zdb -luOlaf Faaland2017-03-061-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For zdb -l, detect when the configuration nvlist in some label l (l>0) is the same as a configuration already dumped. 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.

* zdb: Introduce -V for verbatim importRichard Yao2014-07-171-1/+12
| | | | | | | | | | | | | When given a pool name via -e, zdb would attempt an import. If it failed, then it would attempt a verbatim import. This behavior is not always desirable so a -V switch is added to zdb to control the behavior. When specified, a verbatim import is done. Otherwise, the behavior is as it was previously, except no verbatim import is done on failure.

For consistenty with the vdev_disk.c code the upstream version leverages the Illumos bio interfaces. This makes sense for Illumos but not for ZoL for two reasons. 1) The vdev_disk.c code in ZoL has been rewritten to use the Linux block device interfaces which differ significantly from those in Illumos. Therefore, updating the vdev_file.c to use the Illumos interfaces doesn't get you consistency with vdev_disk.c. 2) Using the upstream patch as is would requiring implementing compatibility code for those Solaris block device interfaces in user and kernel space. That additional complexity could lead to confusion and doesn't buy us anything. For these reasons I've opted to simply move the existing vn_rdwr() as is in to the taskq function. This has the advantage of being low risk and easy to understand. Moving the vn_rdwr() function in to its own taskq thread also neatly avoids the possibility of a stack overflow. Finally, because of the additional work which is being handled by the free taskq the number of threads has been increased. The thread count under Illumos defaults to 100 but was decreased to 2 in commit 08d08e due to contention. We increase it to 8 until the contention can be address by porting Illumos #3581.

The script has been updated to download the latest documentations packages for Solaris and extract the needed ZFS man pages. These will still need a little markup to handle changes between the Solaris and Linux versions of ZFS. Howver, they should be pretty minor I've tried hard to keep the interface the same. In additional to the script update the zdb, zfs, and zpool man pages have been added to the repo.
