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?

Thanks.

  • Do you unmount /tmp before resize and dd ? – Maxiko Feb 15 '16 at 9:19
  • not really ... I was not aware about and ran it accidentyl . – Krishna Bhatt Feb 15 '16 at 9:23

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.

Anyway, if xvda1 was your data partition, unfortunately your data are gone. Sorry...
