Description of problem:

It looks like that dd command with seek_bytes is not supported on centos6

Could you please confirm this?
How can we run this test on centos 7 if the above is true
Comment 1 Ashish Pandey 2017-12-01 07:02:43 UTC 
Please try one of these command to make sure it is working fine on centos 6

dd if=/dev/urandom of=./test_file bs=1000 count=1 oflag=seek_bytes,sync seek=2050 conv=notrunc

What do we need to do next? My patch is waiting on this.
Comment 5 Nigel Babu 2017-12-04 08:35:26 UTC 
You should be able to SSH in as jenkins.gluster.org. I'll take back the machine next Monday unless requested on the bug.
Comment 6 Ashish Pandey 2018-01-15 06:29:31 UTC 
Nigel,

Have you moved regression on centos7?

No. Please read the notes on last week's maintainer meeting to understand why this is taking time.
Comment 8 Nigel Babu 2018-01-19 00:28:26 UTC 
Machine back in the pool.
