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! 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

Hi, We run four-node Lustre 2.3, and I needed to both change hardware under MGS/MDS and reassign an OSS ip. Just the same, I added a brand new 10GE network to the system, which was the reason for MDS hardware change. I ran tunefs.lustre --writeconf as per chapter 14.4 in Lustre Manual, and everything mounts fine. Log regeneration apparently works, since it seems to do something, but

All, I''ve added a new 2.2 TB OST to my cluster easily enough, but this new disk array is meant to replace several smaller OSTs that I used to have of which were only 120 GB, 500 GB, and 700 GB. Adding an OST is easy, but how do I REMOVE the small OSTs that I no longer want to be part of my cluster? Is there a command to tell luster to move all the file stripes off one of the nodes?

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.

Hi, I appreciate any help that can be given. For the life of me, I cannot create a writeable share on a specific box - a fairly new install of Fedora Core 5. I have posted on several forums over the past 2 weeks, but haven't gotten anywhere with the advice given, so I'm turning to this list as my last hope. This box runs as an NIS client, but I have had no problems with NIS. The problem

Hello, lfs prints different obd(idx) compared to lctl dl. We use single striping. cluster1 tmp # lfs find --obd scia-OST0017_UUID /data/scia/L0/V0.00/20100327/SCI_NL__0PNPDE20100327_193441_000040582088_00071_42209_1158.N1 /data/scia/L0/V0.00/20100327/SCI_NL__0PNPDE20100327_193441_000040582088_00071_42209_1158.N1 cluster1 tmp # lfs getstripe

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

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

I''m a Lustre newbie who just joined this list. I''d appreciate any help on the following Lustre 2.4 issue I''m running into: Every time I mount the MDT, the mount appears to succeed but /var/log/messages contains the message: "LustreError: 11-0: lustre-MDT0000-lwp-MDT0000: Communicating with 0@lo, operation mds_connect failed with -11". The MDT uses 4 local

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

Guys, I'm having troubles with Rmpi on Linux. I got it to work on windows, but on Linux (SuSE 64 bit), using OpenMPI, I can't seem to get it to work :( When I do library(Rmpi) I get the warning: mca: base: component_find: unable to open osc pt2pt: file not found (ignored) Interestingly enough all the examples from the snow tutorial ( http://www.sfu.ca/~sblay/R/snow.html) work despite

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

Folks, OK found it, omega.cc looks for multiple DB definitions and adds it to the search list. If the dbs are only one directory lower (e.g. not in default as in beta/default, but only "beta"), then modifying database_dir setting as follows will work: database_dir /svr/hda1/xapian then, ./omega.cgi 'P=pda' FMT='xml' DB="beta" DB="gamma"

Hello, I am having trouble installing the server modules for lustre 2.1.4 and use mellanox''s OFED distribution so we may use infiniband. Would you folks look at my procedure and results below and let me know what you think? Thanks very much! The mellanox ofed installation builds and installs some kernel modules too, so I used this method to ensure OFED compiled against the correct

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

Hi all, IHACWHAC (I have a colleague who has a customer - hello, if you''re listening :-) who''s trying to build and test a scenario where he can salvage the data off the (internal ?) disks of a T2000 in case the sysboard and with it the on-board raid controller dies. If I understood correctly, he replaces the motherboard, does some magic to get the raid config back, but even
