Subject: LU-13417 test: add mkdir_on_mdt0()
X-Git-Tag: 2.14.53~91
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=54fb8458db0bff4fdfe42ba7476de3129d7606cd;p=fs%2Flustre-release.git

LU-13417 test: add mkdir_on_mdt0()

Once default LMV is set on ROOT, and default stripe offset is "-1",
mkdir may not create directory on MDT0, but it's a premise for many
tests. Add a function mkdir_on_mdt0() to create directory on MDT0
by "lfs mkdir -i 0".

Replace mkdir with mkdir_on_mdt0() for such tests in sanity.sh and
sanityn.sh.
