Dear, everyone We have stuck with the problem that the OSS connect one dead client or one with changed IP address all the time until we reboot the dead client. From the OSS log message, we can get the information as follows: Jul 7 14:45:07 com01 kernel: Lustre: 12180:0:(socklnd_cb.cLustre: 12180:0:(socklnd_cb.c:915:ksocknal_launch_packet()) No usable routes to 12345-202.Lustre:

Hi all, I used the method described below to build client rpms with the source kit lustre-1.8.5.tar.gz. There was only one error reported during the make rpms, relating to lustre-iolit-1.2-root, but the rpms were built under /usr/src/packages/RPMS/x86_64. The rpms lustre-modules, lustre and lustre-tests were then installed smoothly without any complaints. But the subsequent "modprobe

Hello, We had a problem with our disk controller that required a reboot. 2 of our OSTs remounted and went through the recovery window but clients hang trying to access them. Also /proc/fs/lustre/obdfilter/$UUID/ is empty for that OST UUID. LDISKFS FS on dm-5, internal journal on dm-5:8 LDISKFS-fs: delayed allocation enabled LDISKFS-fs: file extents enabled LDISKFS-fs: mballoc enabled

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

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
