We made sure that write caching is disabled as those RAID arrays are not equipped with NVRAM (could be added tough, but the customer did not yet). Runs marvelously. Its also running on some individual servers in that cluster as well. Well and although the cluster is spread across two locations about 1 kilometer from each other and it was said that power supply could not fail... well it failed once for both data centers and the cluster survived that just fine ;-). BZW I didn't broke that GPG signature. It seems the mailinglist software being used for the xfs mailinglist mangles mails. -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
