[Gluster-devel] Statedumps as non-root can not be saved (under /var/run/gluster/...)

[Niels de Vos]

Hi,

Recently a new ability to trigger statedumps through the Gluster-CLI [0]
has been added. This makes it possible to get statedump from
applications that use gfapi. By default, statedumps are saved under
/var/run/gluster/... and this directory is only writable by root.
Applications that use gfapi do not require root permissions (like QEMU),
and therefore fail to write the statedump :-/

One approach would be to create a "gluster" group and give the group
permissions to write to /var/run/gluster/... Other 'fixes' include
setting ACLs on the directory so that specified users can write there.
because many daemons have a "home directory" that does not exist, it
probably is not a good idea to use $HOME to store statedumps.

What suggestions do others have?

Thanks,
Niels
