Description Hannes Landeholm 2011-08-18 22:17:52 UTC

Running a ZFS + Gluster stack could enable a range of useful features. However ZFS is based on solaris which implements the xattr model that was developed for nfsv4. This model does not support extended attributes on symlinks. It's a shame that such a small issue blocks deployment.

One fix for this is to write a workaround for it in gluster if it would be simple rather than waiting for a stable patch for zfs which might never come since it's fundamentally an incompatibility in capability specifications.

Hi Hannes,

I saw that there were few patches from ZFS-FUSE team to handle this issue. Did that work for you?

Comment 2 Hannes Landeholm 2011-08-22 09:32:47 UTC

Yes. With the new fuse patches the issue was resolved.

Comment 3 Amar Tumballi 2011-09-09 15:32:13 UTC

Issue closed as per comment from reporter.

Currently to use GlusterFS on any platform, one need to make sure xattrs are supported for all type of files.

Reporter marked it as working after applying zfs patch , no fix went from glusterfs.so leaving the bug status as it is.
