this may be an stupid question. but .
1. does Lustre client directly access SAN/storage (like GFS, OCFS or
Sun Cluster SVM)
2. if client connects over network,
a. will TCP/IP performance directly hit on CFS
b. cannot I keep client on same machine as OSS/MDS etc.

Dear list,
with versions <= 1.8.0.1 is there a more elegant way of blocking
clients from mounting a Lustre fs than configuring IP tables accordingly?
Is it correct that with versions >= 2.0 Kerberos will deliver this
'functionality' as I can enforce the client to authenticate (which
it can't if
Hi all,
I'm copying around data between 2 MDTs in a test system. Having mounted
the partitione as 'ldiskfs', I had a look in MDT/ROOT. I found all my
test data there, but I'm puzzled by the indicated file sizes. For
example I had put one of my holiday's movies, it's 40MB. On the
ldiskfs-mounted MD

No, client only communicates with the server, and only a single server
will access storage at any one time.

Hi,
The manual has following instruction for erasing a file system.
If you have a separate MGS (that you do not want to reformat), then add
the "writeconf" flag to mkfs.lustre on the MDT, run:
$ mkfs.lustre --reformat --writeconf –fsname spfs --mdt --mgs /dev/sda
I am not sure, but wouldn't this

I don't think there is any other easy way to do this. I believe LLNL
had a patch to essentially impleme

I meant '--mgsnode' and not '-mgs' in my command.
$ mkfs.lustre --reformat --writeconf –fsname spfs --mdt
--mgsnode= /dev/sda
