Greetings, I am trying to get the Gluster "cluster/stripe" translator to work with a "storage/posix" directory on a tmpfs file system. Although "cluster/unify" works, it presents a limit to file sizes which may be created that I was hoping to avoid with striping. The documentation here: http://www.gluster.org/docs/index.php/GlusterFS_Translators_v1.3#Stripe_Translator indicates that "Stripe needs extended attribute support in the underlying FS". >From what I have been able to find, "recent" kernels have extended attributes enabled when tmpfs is enabled. However, I get the following error when trying to create a file (directory creation is fine): # df -hP /tmp/scratch Filesystem Size Used Avail Use% Mounted on glusterfs 12G 24K 12G 1% /tmp/scratch # touch /tmp/scratch/foo touch: cannot touch `/tmp/scratch/foo': Operation not supported >From this posting, it looks like there is also a "USER extended attributes" which might be needed in order to make striping work on a tmpfs filesystem: http://acl.bestbits.at/pipermail/acl-devel/2007-April/002031.html Can someone please clarify the difference between extended attributes and user extended attributes? Has anyone successfully gotten "cluster/stripe" working on a tmpfs file system? Does anyone have a lab setup where they could try the above patch and gluster on tmpfs? (If it works, I think it would be worth pushing the patch into the main kernel.org tree.) Might there be something else wrong that is preventing striping from working? Or a workaround to get striping working on filesystems without extended attributes? I am using fuse-2.7.2glfs8, glusterfs-1.3.7, and linux-2.6.20.20. Thanks, Nathan
