To summarize the explanations: My VIB file implements all required immediate actions on install and the recurring action (resource group modification) on every system boot. On normal system startups the line # chkonfig: on 10 90 (line 7) will make sure that it is executed before the likewise service startup script /etc/init.d/lwsmd, because it provides a lower startup sequence order number (10) then the latter. In this case the script will also restart the likewise daemon lwsmd to make it pick up the changed nf file (Kudos to William Lam for pointing out this undocumented feature). However, the script will also immediately be executed when the package is installed, and then the string "install" will be passed as a second parameter. It will then only do the resource group modification. This script will be executed on two occasions: At every system startup it will be executed with the parameter "start" passed.

modify the system in a way that - under normal circumstances - would render the system completely unsupported (you tinker with a bootbank file that should normally only be touched by the system install and update procedures),.

My hair stood on end when I was reading this! The instructions given The KB article describes a hard way to persistently change the file and provides instructions on how to update the bootbank file s.v00 to include a changed copy of the file. is that the file is read-only and cannot be easily changed in a persistent way. Second, the system resource pool for the likewise daemons needs to be modified to provide more RAM. Īpparently there are two actions needed to fully fix the issue: First, the buffer size in the configuration file /etc/likewise/openldap/nf needs to be raised - the article suggest doubling it from 4096 to 8192. But - sorry, VMware - this resolution is tremendous and furthermore incomplete! Let me explain why.
