It is account and volume management which is crippled while the servers can not synchronize the relevant data with each other. SCM is the machine to perform such operations on. If your former SCM machine is down you are already out of luck and taking down the update daemons on the other servers does not make things worse. File service itself is not affected by update daemons being down. Note that you most probably want to take back / recreate the server which used to be your SCM as soon as possible, as long as it hosts some volumes or volume replicas. It is not supported to run with reduced number of replicas indefinitely, the modification logs will fill up at some point. Regards, RuneReceived on 2010-04-09 02:36:26
