I ran this command on Ubuntu to resize the
/tmp and after that there is segmentation fault coming.
dd if=/dev/zero of=/dev/xvda1 bs=1024M count=2
Its our live server. Is there any way to get it working or get the data?
The segmentation fault was probably related to the selected block size: with
bs=1024M you asked for 1GB-sized blocks, which can be too much for your server.
xvda1 was your data partition, unfortunately your data are gone. Sorry...
