Hi. I'm re-directing the conversation to the correct list. Maybe I misunderstand what you are saying, but it sounds like your nodes re-image themselves every time they reboot. If they 100% start from a clean slate, including wiping the PVFS storage space, then yeah, you'll lose data. One way to avoid this is to adjust your re-imaging process to leave certain partitions or file systems alone. You could re-image the / partition, but keep a separate /pvfs2-data partition, for example, which you would never wipe on re-imaging. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
