[ ... ] BTW, while 30TB is probably still in the real of the plausible if excessively large, and this is a 64b system, this is a good example of a gratuitously large filetree and an excessively wide RAID set under it. http://www.sabi.co.uk/blog/0805may.html#080516 A large single filetree only makes sense if one need a large and unified free space pool... But in this application all files are essentially independent and preallocated. A more manageable setup might have been a set of 4-8TB filetrees, for example on a group of 3TBx 2+1 or even 4+1 (split in two partitions) RAID5 sets. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
