cannot start namenode

["Peng, Wei" <We...@xerox.com>]

Hi,

 

I was copying some files from an old cluster to a new cluster.

When it failed copying, I was not watching it. (I think over 85% of data
has been transferred).

The name node crashed, and I cannot restarted it.

 

I got the following error when I try to restart the namenode

Hadoop-daemon.sh: line 114: echo: write error: No space left on device.

 

Does someone know how to fix this problem ? I am in urgent need to
restart this cluster...

 

Thanks a lot

Wei

Possibly a stupid question but have you done a "df -h" on the namenode to verify that you didn't somehow fill up all of the free space on that mount? I can imagine that it would blow up if it was not able to initiate the namenode log for that session (and could potentially explain why it crashed in the first place).
