hmm, judging from errpt and the format of the error message (0511-051 Read failed) i suppose it is indeed AIX (at least it looks like it). Still, it would help to know the version.

You do know that

Code:
nohup time dd if=/dev/zero of=/filesystem/file_$count bs=512m count=4 &

will have all the writer processes run in parallel in the background, do you? If i had to take a wild guess i'd ask myself if the blocksize might be kept in memory and if the 10 parallel dd-instances maybe taxed memory too much. You might want to run this again with a smaller blocksize and a higher count to make up.

What rbatte1 suggested (not mounted FS) seems still the most likely cause to me. If this can be verified not to be the case you might consider running "vmstat" in one window and then start the job again in another to see a more detailed picture of what is happening.

I hope this helps.

Examples "vgmerge -v databases my_vg" merges the inactive volume group named "my_vg" into the active or inactive volume group named "databases" giv- ing verbose runtime information. SEE ALSO
