Hi! We''ve started to poke and prod at Lustre 1.6.4.1, and it seems to mostly work (we haven''t had it OOPS on us yet like the earlier 1.6-versions did). However, we had this weird incident where an active client (it was copying 4GB files and running ls at the time) got evicted by the MDS and all OST''s. After a while logs indicate that it did recover the connection

on our cluster that has been running lustre for about 1 month. I have 1 MDT/MGS and 1 OSS with 2 OST''s. Our cluster uses all Gige and has about 608 nodes 1854 cores. We have allot of jobs that die, and/or go into high IO wait, strace shows processes stuck in fstat(). The big problem is (i think) I would like some feedback on it that of these 608 nodes 209 of them have in dmesg

I am running on CentOS 5 distribution without adding any updates from CentOS. I am using the lustre 1.6.4.1 kernel and software. I have two NICs that run though different switches. I have the lustre options in my modprobe.conf to look like this: options lnet networks=tcp0(eth1,eth0) My MGS seems to be only listening on the first interface however. When I try and ping the 1st interface (eth1)

Hi, I am having problem to bring up the network using lustre 1.6.4.1 (2.6.18-8) with OFED-1.3 (InfiniBand).

I am having a problem writing/saving to a SMB share with O2K3(Word). In WORD, if I File/SaveAs \\machine\share\fred.doc - the windows machine hangs completely (Explorer+Word immediately, then all other processes after a period of say 1min). Most other scenarios succeed: ok: File/SaveAs C:\fred.doc, then move to \\machine\share using explorer. ok: Outlook.PST file on \\machine\share can be written

Hello, I'm using CentOS 5.5 / 16bit as a virtual machine in VMWare Workstation and have installed the "VMWare Tools" by running vmware-install.pl and vmware-config-tools.pl but can't figure out how to make the VM shutdown, when I shutdown the Windows PC hosting it. Does anybody please have any hints or scripts? Do I need to use any VMWare modules if I just want to shutdown the

Dear All, Yesterday evening or cluster has stopped. Two of our nodes tried to take the resource from each other, they haven''t seen the other side, if I saw well. I stopped heartbeat, resources, start it again, and back to online, worked fine. This morning I saw this in logs: Feb 22 03:25:07 node4 kernel: Lustre: 7:0:(linux-debug.c:98:libcfs_run_upcall()) Invoked LNET upcall

Chris, Perhaps you need to perform some write_conf like command. I''m not sure if this is needed in 1.6 or not.

Hi again! Same setup as before (Lustre 1.6.2 + 2.6.18 kernel). This time things suddenly started to be very slow (as in periodically stalling), and we found a bunch of llog_ LustreErrors on the MDS. Some time later stuff had automagically recovered and is back to normal speed. Any idea on the meaning/cause of these errors? What are the seriousness of "LustreError" errors in
