Hi, Lustre manual 1.6 v18 says that that in production lustre debug level should be set to fairly low. Manual also says that I can verify that level by running following commands: # sysctl portals.debug This gives ne following error error: ''portals.debug'' is an unknown key cat /proc/sys/lnet/debug gives output: ioctl neterror warning error emerg ha config console cat

I installed 1 MDS , 2 OSS/OST and 2 Lustre Client. My MDS shows: [code] [root at MDS ~]# lctl list_nids 10.94.214.185 at tcp [root at MDS ~]# [/code] On Lustre Client1: [code] [root at lustreclient1 lustre]# lfs df -h UUID bytes Used Available Use% Mounted on lustre-MDT0000_UUID 4.5G 274.3M 3.9G 6% /mnt/lustre[MDT:0]

Hi I used lustre-1.8.3 for Centos5.4. I patched the kernel according to Lustre 1.8 operations manual.pdf. I have a problem when I want to implement quota. My cluster configuration is: 1. one MGS/MDS host (with two devices: sda and sdb,respectively) with the following commands: 1) mkfs.lustre --mgs /dev/sda 2) mount -t lustre /dev/sda /mnt/mgt 3) mkfs.lustre --fsname=lustre

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

whoops, sent from wrong email address, form right address now: Hello, I am using Lustre 2.4.2 and have an OST that doesn't seem to be written to. When I check the MDS with 'lctl dl' I do not see that OST in the list. However when I check the OSS that OST belongs to I can see it is mounted and up; 0 UP osd-zfs l2-OST0003-osd l2-OST0003-osd_UUID 5 3 UP obdfilter l2-OST0003

Hello, We have running lustre 1.8.1 and have met "No space lest on device" error when uploading 500 Gb small files (less then 100 Kb each). The problem seems to depends on the number of files. If we remove one file, we can create one new file, even with Gb size; but if we haven''t remove something we can''t create even very little file, as an example using touch

Hello, When I run a "df -i" in my clients I get 95% indes used or 5% inodes free: Filesystem Inodes IUsed IFree IUse% Mounted on lustre-mds-01:lustre-mds-02:/cetafs 22200087 20949839 1250248 95% /mnt/data But if I run lfs df -i i get: UUID Inodes IUsed IFree I

Hi, I suffered an oss crash where my oss server had a cpu fault. I have it running again, but I am trying to decommission it. I am migrating the data off of it onto other ost''s using the lfs find command with lfs_migrate. It''s been nearly 36 hours and about 2 terabytes have been moved. This means I am about halfway. Is this a decent rate? Here are the particulars, which

I''m evaluating lustre. I''m trying what I think is a basic/simple ethernet config. with MDT and OST on the same node. Can someone tell me if the following (~150 second recovery occurring when small 190 GB OST is re-mounted) is expected behavior or if I''m missing something? I thought I would send this and continue with the eval while awaiting a response. I''m using

Hello, 1) when compiling the lustre modules for the server the ./configure script behaves a bit odd. The --enable-server option is silently ignored when the kernel is not 100% patched. Unfortunatly the build works for the server, but during the mount the error message claims about a missing "lustre" module which is loaded and running. What is really missing are the ldiskfs et al

Hi; One of our OSTs filled up. Once we realized this, we executed lctl --device 9 deactivate on our fs''s combo MDS/MGS machine. We saw in the syslog that the OST in question was deactivated: Lustre: setting import ufhpc-OST0008_UUID INACTIVE by administrator request However, ''lfs df'' on the clients does not show that the OST is deactivated there, unless we *also*

Greetings-- Packages for Lustre 1.0.2 are now available in the usual place http://www.clusterfs.com/download.html This bug-fix release resolves a number of issues, of which a few are user-visible: - the default debug level is now a more reasonable production value - zero-copy TCP is now enabled by default, if your hardware supports it - you should encounter fewer allocation failures

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

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

Hi all, we have two servers A, B as a failover MGS/MDT pair, with IPs A=10.12.112.28 and B=10.12.115.120 over tcp. When server B crashes, MGS and MDT are mounted on A. Recovery times out with only one out of 445 clients recovered. Afterwards, the MDT lists all its OSTs as UP and in the logs of the OSTs I see: Lustre: MGC10.12.112.28 at tcp: Connection restored to service MGS using nid

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