> I think ext3 is a bit slow on so big LUNS, try xfs or similar? there is no official support for xfs in RHEL5, so that is not an option. Besides, I'm talking about a drop of >150mb/s to ~10mb/s read performance when cracking the 2.2T size. This is clearly not in the ext3 (or FS for that matter) magnitude of performance issues. Also, numbers stay the same when dd'ing on the raw device (LUN). -Jens Eero Volotinen <eero.volotinen at iki.fi> Sent by: centos-bounces at centos.org 07/14/2010 11:35 AM Please respond to CentOS mailing list <centos at centos.org> To CentOS mailing list <centos at centos.org> cc Subject Re: [CentOS] GPT Partitions >2.2T with Centos 5.5 http://lists.centos.org/mailman/listinfo/centos -------------- next part -------------- An HTML attachment was scrubbed...
