Hi all, I'm using Ubuntu 14.04 samba 4.1.6 packages, attempting to set up a server for file shares AD clients can use. My previous setup was a simple AD join with a user map file (1 to 1 AD to unix user) that i've been migrating for approximately 7 years, and with the last 2003 AD server removed from the network it stopped working (2008 R2 DC's now). After approximately 2 weeks of

This may be in the documentation. If so, I missed it. If a site has multiple Lustre file systems, the documentation implies that there only needs to be a single MGS for an entire site (regardless of the number of file systems). However, I also know it is fairly common to have a combined MGS/MDT. So here are the questions. 1. If we are going to have several Lustre file systems,

Hi all, Here is the situation: I have 2 nodes MDS1 , MDS2 (10.0.0.22 , 10.0.0.23) I wish to use as failover MGS, active/active MDT with zfs. I have a jbod shelf with 12 disks, seen by both nodes as das (the shelf has 2 sas ports, connected to a sas hba on each node), and I am using lustre 2.4 on centos 6.4 x64 I have created 3 zfs pools: 1. mgs: # zpool

Hi, Our lustre environment is: 2.6.9-55.0.9.EL_lustre.1.6.3smp I would like to change recovery timeout from default value 250s to something longer I tried example from manual: set_timeout <secs> Sets the timeout (obd_timeout) for a server to wait before failing recovery. We performed that experiment on our test lustre installation with one OST. storage02 is our OSS [root at

Hi, I would like to know what TCP/UDP ports should i keep open in my firewall policies on my MGS server such that I can have my MGS server fire-walled. Also if in a event of loss of MGT would it be possible to recreate the MGT without loosing data or bringing the filesystem down (i.e. by using cached information from MDT''s and OST''s) Thanks Anand

Dear all, I wrote the following batch script on a iMac, and ran it on a linux mosix cluster. tu <- read.table("cage.mm5.tags.rna_lib.CAA-CAJ.tu-reshape.table") tu_reshaped <- t(reshape(tu[1:50,], direction="wide", timevar="tu", idvar=c("rna","lib"))) write.table(tu_reshaped, "cage.mm5.tags.rna_lib.CAA-CAJ.tu-reshaped.table")

I have 11 possible predictor variables and use them to model quite a few target variables. In search for a consistent manner and possibly non-manual manner to identify the significant predictor vars out of the eleven I thought the option "select=T" might do.

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

Greetings! I am working with Lustre-2.1.2 on RHEL 6.2. First I configured it using the standard defaults over TCP/IP. Everything worked very nicely usnig a real, static --mgsnode=a.b.c.x value which was the actual IP of the MGS/MDS system1 node. I am now trying to integrate it with Pacemaker-1.1.7. I believe I have most of the set-up completed with a particular exception. The "lctl

In 1.6.0, when creating a MDT, you could specify multiple --mgsnode options and it would failover between them. 1.6.3 only seems to take the last one and --mgsnode=192.168.1.252 at o2ib:192.168.1.253 at o2ib doesn''t seem to failover to the other node. Any ideas how to get around this? Robert Robert LeBlanc College of Life Sciences Computer Support Brigham Young University leblanc at

Any recommendation about the sequence to umount multiple lustre file system with combined MGS/MDT or separate MGS, MDT. Thanks.

OK, so our old MDS had hardware issues so I configured a new MGS / MDS on a VM (this is a backup lustre filesystem and I wanted to separate the MGS / MDS from OSS of the previous), and then did this: For example: mount -t ldiskfs /dev/old /mnt/ost_old mount -t ldiskfs /dev/new /mnt/ost_new rsync -aSv /mnt/ost_old/ /mnt/ost_new # note trailing slash on ost_old/ If you are unable to connect both
