Hi everyone,
I am having some problems testing a GFS system using iozone. I am
running CentOS 2.6.18-128.1.6.el5 and have a two node cluster with a GFS
installed on a shared iSCSI target. The GFS sits on top of a 1.79TB
clustered logical volume and can be mounted successfully on both cluster
nodes.
When using iozone to test performance everything goes smoothly until I
get to a file size of 2GB and a record length of 2048. Then iozone exits
with the error
Error fwriting block 250, fd= 7
and (as far as I can tell) the GFS becomes corrupted
fatal: invalid metadata block
bh = 12912396 (magic)
function = gfs_get_meta_buffer
file = /builddir/build/BUILD/gfs-kmod-0.1.31/_kmod_build_/src/gfs/dio.c,
line = 1225
Can anyone shed some light on what is happening?
Kind regards, Mike O'S
