My company is using lvs and we've noticed a few issues. We have at least one local patch, and plan on making several more. =20 I cribbed and slightly modified an internal wiki page about our proposed changes and bugs. =20 In particular there is at least one verified bug in lvsd (mis-indexed re-read of config file), some missing features (as the documentation implies, or is missing - pulse re-reading the config file, doesn't pay attention to the status of it's child lvsd), nanny doesn't check it's arguments carefully and may unexpectedly exit etc. =20 =20 For a full detailed description of all the issues we've found, and for our proposed solutions, please see: =20 http://clift.org/fred/lvs/lvs.html =20 =20 I have a couple of questions. First, can you direct me to the process for submitting patches for lvs/pulse/nanny, and second, are there other known issues with these programs that we might likely trip over? In particular are there nanny options that currently are arguably non-valid parameters (cause immediate nanny exit) - for example, a timeout of 0 is one. Are there others? =20 =20 Anyway, I'd appreciate anyone's feedback on our proposed changes and the patch submission process. =20 Thanks. =20 Fred Clift [email protected] Verio Inc.
