Hi, I have been tussling with a SAN problem for several weeks now and would like comments from you folks on it.
Situation: Equallogic iscsi san. Primary site has a 2TB volume (1.7TB used per the SAN, 1.5TB used per the operating system). The volume is used as the datastore for a Scalix (used to be HP OpenMail) mail server. File system is ext3 mounted with defaults and yes I plan to redo this over the weekend. It has about 30 million files of which 60% are less than 4K in size. Equallogic uses a 64K strip on its arrays with a 256K block size (not changeable). DR site has 6TB allocated for replicas. My primary problem is that the replication keeps failing for running out of space even though I have 6TB available. I can do the first replica, and sometimes a second or third, but then it starts failing due to lack of space. Change amounts ranges are 200 - 500GB. Even with that I should be able to create a few replicas into 6TB (I would thnk). What have you experienced with SAN's and applications that have millions of small files? What tricks did you use to make them work? Am I barking up the wrong tree and need to go in a totally different direction? cheers, ski -- "When we try to pick out anything by itself, we find it connected to the entire universe" John Muir Chris "Ski" Kacoroski, [email protected], 206-501-9803 or ski98033 on most IM services _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
