Hi,
I'm experiencing what I think is data corruption issues when using the
iSER driver in CERN SLC5.5 (which is based directly off RHEL 5.5).
I just set up stgt with the iSER driver on a mellanox infiniband mesh
with 7 nodes in it. I was having problems with my OCFS2 cluster crashing
randomly on large data writes, so I simplified it down to 1 initiator
and 1 target and an ext4 partition.
The backing store is a 5 TB linux raid 6 softraid, running on SLC 5.5.
The initiators are running open-iscsi on Ubuntu Server 10.04. I'm using
the OFED packages from each respective distro.
On my test setup with 1 target and 1 initiator, copying files with
'dd if=/dev/zero of=/<ext4 array>/zeroes bs=64k count=10000'
generated a whole slew of ext4 errors on the initiator. A subsequent
fsck.ext4 showed thousands of inode errors. Trying to transfer a file
with cp generated similar errors.
Are there any known quirks with the iSER driver, or am I misconfiguring
something? My infiniband connection seems quite stable, and I'm using
ipoib quite heavily right now.
Thanks in advance for any replies,
Matt
