[ndctl PATCH 1/2] ndctl/check-namespace: improve error message in absence of a BTT

When a BTT info block is not found, check-namespace only reported something like: namespace5.0: namespace_check: Unable to recover any BTT info blocks error checking namespaces: No such device or address checked 0 namespaces This can be improved by suggesting a BTT might not have been present on the namespace at all, so emit an additional message such as: namespace5.0: namespace_check: This may not be a sector mode namespace Link: https://github.com/pmem/ndctl/issues/43 Reported-by: Jane Chu <jane.chu(a)oracle.com&gt; Reported-by: Scott Davenport <scott.davenport(a)oracle.com&gt; Signed-off-by: Vishal Verma <vishal.l.verma(a)intel.com&gt; --- ndctl/check.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/ndctl/check.c b/ndctl/check.c index 5969012..365abaf 100644 --- a/ndctl/check.c +++ b/ndctl/check.c @@ -1322,6 +1322,8 @@ int namespace_check(struct ndctl_namespace *ndns, bool verbose, bool force, rc = btt_recover_first_sb(bttc); if (rc) { err(bttc, "Unable to recover any BTT info blocks\n"); + err(bttc, + "This may not be a sector mode namespace\n"); goto out_close; } /* -- 2.20.1
