[lvm-devel] [PATCH v2] clvmd: supress ENOENT error on testing connection

[Eric Ren]

In HA cluster, we have "clvm" resource agent to manage clvmd daemon.
The agent invokes clvmd like: "clvmd -T90 -d0", which  always prints
a scaring error message:

"""
local socket: connect failed: No such file or directory
"""

When specifed with "-d" option, clvmd tries to check if an instance
of the clvmd daemon is already running through a testing connection.
The connect() will fail with this ENOENT error in such case, so supress
the error message in such case.
