Hello, I''ve several problems with quota on our testcluster: When I set the quota for a person to a given value (e.g. the values which are provided in the operations manual), I''m able to write exact the amount which is set with setquota. But when I delete the files(file) I''m not able to use this space again. Here is what I''ve done in detail: lfs checkquota

Are their issues with Samba and Lustre working together? I remember something about turning oplocks off in samba, and while testing samba I noticed this [2010/08/27 17:30:59, 3] lib/util.c:fcntl_getlock(2064) fcntl_getlock: lock request failed at offset 75694080 count 65536 type 1 (Function not implemented) But I also found out about the flock option for lustre. Should I set flock on all

Hi all, I am a grad student at Carnegie Mellon University. I had my course work in advanced storage systems in previous semester, and I am interested to work on Lustre. I prefer to take up a project that could be completed in a duration of a month or two. Since I am a novice w.r.t. my familiarity with Lustre code base, I seek your opinion to choose a project from the list:

This is the strangest problem I have seen. I have a lustre filesystem mounted on a linux server and its being exported to various alpha systems. The alphas mount it just fine however under heavy load the NFS server stops responding, as does the lustre mount on the export server. The weird thing is that if i mount the nfs export on another nfs server and run the same benchmark (bonnie) everything

Hi, thanks for previous help. I have some question about Lustre RPC and the sequence of events that occur during large concurrent write() involving many processes and large data size per process. I understand there is a mechanism of flow control by credits, but I''m a little unclear on how it works in general after reading the "networking & io protocol" white paper. Is

Hi, On a few of the hpc cluster nodes, i am seeing a new lustre error that is pasted below. The volumes are working fine and there is nothing on the oss and mds to report. LustreError: 5080:0:(import.c:607:ptlrpc_connect_interpret()) data3-OST0000_UUID at 192.168.2.98@tcp changed handle from 0xfe51139158c64fae to 0xfe511392a35878b3; copying, but this may foreshadow disaster

Hello everybody, at the following pages: http://www.rit.edu/~rc/docs/Survey_of_Clustered_Parallel_File_Systems_004_LANL.ppt http://www.intel.com/cd/ids/developer/asmo-na/eng/dc/tools/threading/238284.htm?page=2 I read: "[...] Currently, one additional drawback to Lustre is that a Lustre client cannot be on a server that is providing OSTs.

Hello, I googled for a while in order to find a solution to make dovecot work with local and virtual users. My Mailserver setup looks like the following: virtual users are stored in a mysql database, and having their Mailbox here: /srv/mail/$domain/$uid/ Local users have a Maildir folder in their home directory. The only point i found in the web concerning this issue is this post here:

I compiled Lustre with a vanilla 2.6.12.6 kernel, and it seems to work quite well, so far. However, I can''t seem to successfully export a Lustre filesystem via NFS using it, so I''m guessing that NFS export support hasn''t made it into the 1.6beta, yet. Is that correct? Are there plans for another beta with that support included in the near future, or does someone

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

Dear All, We have a really serious problem. This weekend we upgraded our mixed 1.6.0.1 + 1.6.4.1 cluster based on CentOS 4.4 i386 to CentOS 5.1 x86_64. We reformatted all drbd storages, so recreated the whole cluster and copy back from backup. Windows clients reached the cluster through a samba server, but now it''s just not working at all. This is my smb.conf # testparm Load smb

Hi, With help from Oleg we got the right patches applied and NFS working well. Maximum performance was about 60 MB/sec. Last week that dropped to about 12.5 MB/sec and I cannot find a reason. Lustre clients all obtain 100+ MB/sec on GigE. Each OST is good for 270 MB/sec. When mounting the client on one of the OSSs I get 230 MB/sec. Seems the speed is there. How can NFS and Lustre be tuned

This morning I''ve had both my infiniband and tcp lustre clients hiccup. They are evicted from the server presumably as a result of their high load and consequent timeouts. My question is- why don''t the clients re-connect. The infiniband and tcp clients both give the following message when I type "df" - Cannot send after transport endpoint shutdown (-108). I''ve

I installed 1 MDS , 2 OSS/OST and 2 Lustre Client.

Hello All, I''d like to announce the creation of a new lustre-community at lists.lustre.org mailing list. After discussions with the various Lustre parties in the community, we thought there should be a new list to focus the "meta" discussion related to Lustre development in the community, such as how feature design, code development, patch contribution, and landing is
