Subject: LU-160 check the minimum available size of OST in test_155_load()
X-Git-Tag: 2.0.61.0~23
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=dc0317c7150f068cff7343051092236b5c9c29eb;ds=inline

LU-160 check the minimum available size of OST in test_155_load()

Fix test_155_load() in sanity.sh to check whether the minimum available
size of OST is bigger than the large file size. If not, then sanity test
155{a,b,c,d} would be skipped.
