[Stgt-devel] Bug report - create a file on mounted FS (ext3) with dd fails

[Eli Dorfman]

Hi,

I have the following test environment:
Initiator: RH4.4 with OFED1.3.1
Target: RH5.1 with Stgt latest snapshot 20080715
I'm using iser transport

I created an ext3 FS on the device
#mkfs.ext3 /dev/sdc

mounted the device
# mount /dev/sdc /mnt/sdc

Trying to create a file on the mounted FS
# dd if=/dev/zero of=/mnt/sdc/tempfile bs=1k count=40M

I got the following error on the initiator:

dd: writing `/mnt/sdc/tempfile': Read-only file system
1489+0 records in
1488+0 records out

And the following messages on the target:
tgtd: iser_rx_progress(1101) entry

Please advise.
