Hi,
I am trying to run a performance test on Lustre, running Beta 5
software. I am getting the following error message:
LustreError: 4504:0:(client.c:579:ptlrpc_check_status()) @@@ type
== PTL_RPC_MSG_ERR, err == -28
Any ideas what might be the problem?
More detail below.
Thanks,
-David
I have a simple 2-node setup running beta 5 software. One node is
exporting a 1 Gig disk. I have created a single
file which is as big as I could make it before running out of disk
space.
On the second node, I have used losetup to create a loop0 device on top
of that same shared file. Then I run
xdd device test program to read and write to sectors on that loop0
device. The test can run a minute or two without
a problem, but then seems to start to degrade. Sometimes the reads
return success, but
only a partial read of the data, sometimes they return -1 with an errno
that just tells me I/O error.
