Sure. LVM is apples. OCFS is oranges. (-: OCFS is NOT a volume manager. It's a filesystem. Consider the hardware configuration where you have a hard disk that is physically connected to two or more computers through a shared SCSI bus or fiberchannel. (OCFS architecturally supports up to 32 hosts.) An OCFS filesystem exists on a single disk or partition, but on multiple computers in a cluster. OCFS defines a data layout on that shared disk and implements the basic filesystem operations -- mkdir, creat, read, write, unlink, and all the rest. It's designed so that all the computers in the cluster can be creating and destroying files at the same time, with an on-disk locking protocol to keep the metadata consistent. > tnx, yrwlcm. -- Bob Miller K<bob> kbobsoft software consulting http://kbobsoft.com [EMAIL PROTECTED] _______________________________________________ EuG-LUG mailing list [EMAIL PROTECTED] http://mailman.efn.org/cgi-bin/listinfo/eug-lug
