Hello!
I'm operating a GlusterFS installation running 2.0.7. After the good
experience with a patched 3.1.2 in an other project I think about an
upgrade.
It's a distribute/replicate setup over two servers with four bricks
each. Some of the files have metadata in their extended attributes:
# getfattr -m "" -Rd .
# file: directory
trusted.afr.Data1VolA=0sAAAAAAAAAAAAAAAA
trusted.afr.Data1VolB=0sAAAAAAAAAAAAAAAA
trusted.glusterfs.dht=0sAAAAAQAAAAAAAAAAP////g==
# file: directory/file
trusted.afr.Data1VolA=0sAAAAAAAAAAAAAAAA
trusted.afr.Data1VolB=0sAAAAAAAAAAAAAAAA
# file: directory/anotherfile
trusted.glusterfs.dht.linkto="Data2Mirror\000"
Is there any painless way to switch from the existing, manually
configured GlusterFS 2.x backend to the new glusterd generated setup in
3.1? An automatic or manual rewrite of the metadata?
Of course I'm able to recycle the existing volfiles and ignore glusterd,
but I like the new approach and I would prefer to use it. I'm also able
to dump / restore the content of the filesystem, but it will take ages
to do so :-)
Thanks for your feedback!
