Add ESXi df check to verify presence of ESXi OS filesystems. #40

Open sttardy opened 3 years ago

sttardy commented 3 years ago

Currently HyperCheck checks that these vfat filesystems are present and warn if at 100%.

cmd = "df -h | grep vfat | grep 100%"

HyperCheck should also check for the presence of the filesystems. Sometimes these filesystems go "missing" which prevents ESXi from upgrading/installing causing Hyperflex upgrade to fail.

In python, probably make sure len(cmd(df | grep vfat)) >= 3, otherwise warn about possible missing OS filesystem. Or verify the return code of cmd(df | grep vfat) = 0. Or maybe warn when return code of cmd(df | grep vfat) != 0.
