What exactly does that do?

Hi. Many thanks for your responses. Generally, the qualities of Lustre
appear great for a Storage Repository for virtual machine images in
XenServer since you would get a combination of fault tolerance, a
pretty much infinitely scalable distributed storage pool, speed and
ability to

Hello again,
Not sure if it is interesting to be noted, but if I use the following
command, my memory is freed:
sync; echo 3 /proc/sys/vm/drop_caches
What is surprising, though, is that the cache never expires (at least
it remains in memory for several days at the least).

Hello,
All servers and clients are having Lustre 1.8, on SLES 10 SP2. Clients
use patchless kernels, using same base revision as the ones for the
patched kernel servers.
We recurrently encounter this error :

Hi David,
I did some experiments last year with Lustre 1.6.x and a Dell iSCSI
enclosure. It was a little slow (proof of concept mainly) due to sharing MDT
and OST traffic on a single GigE strand, but as long as the operating system
presents a valid block device, Lustre works fine.

Hi,
After modification of TCP statck on OSS, it seems that failed
clients can reconnect again. The pressure test has persisted for 12 hours.
You should check for error messages on the server that might indicate
why it is having a problem. If all of the clients are

Hi Andreas. NFS is fine for XenServer so think it is worth evaluating
Lustre as a proof of concept for storage pool. First step I want to
take is to setup a single node (everything on the one node as you have
identified) to ensure XenServer can properly connect to NFS through
Lustre.
Either way Andres. We appreciate the talk. My masters OS design class
talked about this for 45 mins today :-) You are a celebrity.
