In testing how to cope with naive users generating millions of tiny
files, I noticed some surprising (to me) behavior on a lustre 2.10/ZFS
0.7.0 system.
The test directory (based on actual user data) contains about 4 million
files (avg size 8.6K) in three subdirectories. Making tar files of

Hi All,
We are gradually updating a cluster (OS, etc.) in-place, basically
switching blocks of nodes from the old head node to the new. Until we can
re-arrange the fabric at the next scheduled machine room power shutdown
event, we are running two independent Infiniband subnets. As I can't find
On a somewhat-related question, what are the expected trade-offs when
splitting the "striping" between ZFS (striping over vdevs) and Lustre
(striping over OSTs)?
Specific example: if one has an OSS with 40 disks and intends to use
10-disk raidz2 vdevs, how do these options compare?:
A) 4 OSTs,
orts running to match the IO potential.

Hi All,
I've been evaluating some of the newer options that should be available
with Lustre 2.9 on top of ZFSonLinux 0.7.0 (currently at rc3).
Specifically, trying 16MB RPCS/blocks on the OSTs and large dnodes on the
MDTs.
I've gathered bits and pieces from discussions in the zfs and lustre
Hi All,
I'm attempting to install Lustre on ZFS on EL6.7 using Truescale HCAs.
Not surprisingly, this involves several pre-release versions of various
packages. Also not surprisingly, there are some snags.
