similar to: read-only on certain client versions

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 r-helpers, Can anyone suggest why lm() doesn't complain here: summary(osss.lm1 <- lm(logOdds ~ c.setSize %in% task, data = osss)) whereas in package:nlme (and in package:lme4) osss.lmL <- lmList(logOdds ~ c.setSize %in% task | subj, data = osss) # Error in `contrasts<-`(`*tmp*`, value = "contr.treatment") : # contrasts can be applied only to factors with 2 or more

We are seeing some disturbing (probably due to our ignorance) behavior from lustre 1.6.3 right now. We have 8 OSSs with 3 OSTs per OSS (24 physical LUNs). We just created a brand new lustre file system across this configuration using the default mkfs.lustre formatting options. We have this file system mounted across 400 clients. At the moment, we have 63 IOzone threads running

Hi everyone, I have seen this question here before, but without a very satisfactory answer. One of our half a dozen clients has lost access to a set of OSTs: > lfs osts OBDS:: 0: lustre-OST0000_UUID ACTIVE 1: lustre-OST0001_UUID ACTIVE 2: lustre-OST0002_UUID INACTIVE 3: lustre-OST0003_UUID INACTIVE 4: lustre-OST0004_UUID INACTIVE 5: lustre-OST0005_UUID ACTIVE 6: lustre-OST0006_UUID ACTIVE

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

lustre-1.8 has OSD structures in place, what do I need to add in to make it work with OSD T10 standard? could anybody point me to some docs mentioning lustre internals - OSTs, OSSs, OBDs, and control flow when a read/write call is invoked by a client. thanks. -------------- next part -------------- An HTML attachment was scrubbed...

Our current Lustre servers run the version 1.8.1.1 with the regular ldiskfs. We are looking to expand our Lustre file system with new servers/storage and upgrade to all the lustre servers to 1.8.4 as well at the same time. We would like to make use of the ldiskfs-ext4 on the new servers to use larger OSTs. I just want to confirm the following facts: 1. Is is possible to run different versions

Dear Martin Maechler, I came accross your valuable contribution in the domain of statistical computing through Web site. I can't but appreciate your great endeavour. I would be grateful to you if you could kindly suggest me or help me to utilize the free statistical pckage like R with Mannual. I am esepcially interested in Time Series Analysis and plotting of experimental

Hi Experts, I remember we had this discussion before, but could find it. Can I run a command to generate a "Compiled catalog" for a specific node (on the master node)? And apply this on the client node? What are the limitations for doing this? Basically we have special handling for the webserver/CA part of puppet. Thank you very much! -Yushu

Hi, i just want to know whether there are any alternative file systems for HP SFS. I heard that there is Cluster Gateway from Polyserve. Can anybody plz help me in finding more abt this Cluster Gateway.

Hello Lustre Experts I am trying to solve a problem with very slow "ls" and other big amount of file operations but good overall read/write rates. We are running a small cluster of 3 OSSs with 9 OSTs, 1MDS (with SSD MDT) and currently two clients. All server nodes are centos 5.2 with lustre 1.8.1 while the clients are centos 5.4 with lustre 1.8.3. All components are networked with DDR

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

at least once a week I receive such an attack coming from a different ip. I will read the articles. Thanks again to everyone. Regards, Rodrigo Lang. 2010/6/29 Kenny Watson <kwatson at geniusgroupltd.com> > Hi, you can use fail2ban >

Hello, in preparation for CentOS 6.5 I was trying to build Lustre 1.8 client on CentOS 6.4 updated with 2.6.32-431 kernel.

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

First email was rejected due to size so the log files are inline in the msg now.. I have NEVER had so much trouble with a samba PDC before. I need to turn in my unix admin license, this is pathetic... Anyway, I am here. When trying to join a domain with the administrator account I get "no mapping between account name and security ID's was done" And the joining fails... All the
