This morning I''ve had both my infiniband and tcp lustre clients hiccup. They are evicted from the server presumably as a result of their high load and consequent timeouts. My question is- why don''t the clients re-connect. The infiniband and tcp clients both give the following message when I type "df" - Cannot send after transport endpoint shutdown (-108). I''ve

Hello, I''ve several problems with quota on our testcluster: When I set the quota for a person to a given value (e.g. the values which are provided in the operations manual), I''m able to write exact the amount which is set with setquota. But when I delete the files(file) I''m not able to use this space again. Here is what I''ve done in detail: lfs checkquota

We seemed to have it a stumbling block when building with the above (supported) versions. Our process... 1. Start with stock rhel5 2.6.18-8.1.14 source tree 2. Configure InfiniBand support out of the the kernel (we will build OFED separately). 3. Apply the 1.6.4.2 kernel patches to the kernel source. 4. Build the kernel. 5. Build OFED 1.2 against the patched kernel 6. Build Lustre using

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

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

Hello everybody, at the following pages: http://www.rit.edu/~rc/docs/Survey_of_Clustered_Parallel_File_Systems_004_LANL.ppt http://www.intel.com/cd/ids/developer/asmo-na/eng/dc/tools/threading/238284.htm?page=2 I read: "[...] Currently, one additional drawback to Lustre is that a Lustre client cannot be on a server that is providing OSTs. This solution is being worked on and may be
