Hello all, I'm trying to take advantage of the shard xlator, however I've found it causes a lot of issues that I hope is easily resolvable
1) large file operations work well (copy file from folder a to folder b 2) seek operations and list operations frequently fail (ls directory, read bytes xyz at offset 235567) 3) Another issue is samba shares through samba-vfs show all files as 4MB, I've also seen this when mounting with fuse, however nfs-ganesha reflects correct file sizes always- Turning off the shard feature resolves this issue for new files created in the volume. mounted using the gluster fuse mount here's my volume settings, please let me know if there's some changes I can make.
