[Gluster-devel] Serious problem doing a perl operation

[Einar Gautun]

Hi all,

I've found a serious problem doing this command:

perl -i -pe 's/something/somethingelse/' filename 

from a gluster mount. This command does remove the content of the file,
making it 0 bytes in glusterfs v3.2.0, and in glusterfs v3.2.3 it also
kills the client so the mountpoint have to be unmounted and mounted
again.

Is this a known problem or does the inline editing of the -i switch in
perl doing something unsupported fileop?

 

Regard

Einar Gautun

 

Info:

 

Server and client: Centos 5.6 with glusterfs rpm packages:

 

glusterfs 3.2.3 built on Aug 23 2011 05:40:50

Repository revision: git://git.gluster.com/glusterfs.git

 

The command for blanking the file and crashing the client:

 

perl -i -pe 's/something/somethingelse/' filename

 

TRACE from client:
