Illumos 4891 - want zdb option to dump all metadata
4891 want zdb option to dump all metadata Reviewed by: Sonu Pillai <[email protected]> Reviewed by: George Wilson <[email protected]> Reviewed by: Christopher Siden <[email protected]> Reviewed by: Dan McDonald <[email protected]> Reviewed by: Richard Lowe <[email protected]> Approved by: Garrett D'Amore <[email protected]> We'd like a way for zdb to dump metadata in a machine-readable format, so that we can bring that back from a customer site for in-house diagnosis. Think of it as a crash dump for zpools, which can be used for post-mortem analysis of a malfunctioning pool References: https://www.illumos.org/issues/4891 https://github.com/illumos/illumos-gate/commit/df15e41 Porting notes: - [cmd/zdb/zdb.c] - a5778ea zdb: Introduce -V for verbatim import - In main() getopt 'opt' variable removed and the code was brought back in line with illumos. - [lib/libzpool/kernel.c] - 1e33ac1 Fix Solaris thread dependency by using pthreads - f0e324f Update utsname support - 4d58b69 Fix vn_open/vn_rdwr error handling - In vn_open() allocate 'dumppath' on heap instead of stack - Properly handle 'dump_fd == -1' error path - Free 'realpath' after added vn_dumpdir_code block Ported-by: kernelOfTruth [email protected] Signed-off-by: Brian Behlendorf <[email protected]>
