As per the discussions with Shruti, from Everglades onwards we are failing both data/metadata operations on a file if any split-brain is present. |
Description of problem: ====================== Getting the extended attributes of a file which is in data-split-brain state gives "Input/Output" error whereas Setting the extended attributes on a file which is in data-split-brain state is still allowed. Version-Release number of selected component (if applicable): ============================================================== glusterfs 3.4.0.35.1u2rhs built on Oct 21 2013 14:00:58 How reproducible: ================== Often Steps to Reproduce: =================== 1.Create 1 x 3 replicate volume. Set self-heal-daemon to off. Start the volume 2.Create 2 fuse mounts. 3.From one mount point create a file : " dd if=/dev/urandom of=./test_file bs=1M count=1" 4. Bring down brick1 and brick2 5. From mount1 write data to "test_file": " dd if=/dev/urandom of=./test_file bs=2M count=1" 6. Bring back brick1 . Bring down brick3 7. From mount2 write data to "test_file" : " dd if=/dev/urandom of=./test_file bs=3M count=1" 8. Bring back brick2. Bring down brick1 9. From mount2 write data to "test_file" : " dd if=/dev/urandom of=./test_file bs=4M count=1" 10. Bring back brick1 and brick3. Note: At this state the file is in split-brain state. 11. From mount point set an extended attribute on the "test_file" {Successful} 12. From mount point get the extended attribute on the "test_file" Actual results: ================ getfattr fails with Input/output error. [2013-11-12 10:29:36.865710] W [fuse-bridge.c:4160:fuse_xattr_cbk] 0-glusterfs-fuse: 100: GETXATTR((null)) /test_file => -1 (Input/output error) Expected results: ================= TBD Additional info: ================= Following are the operations that are allowed on the file which are in data-split-brain state creating hardlinks creating symlinks mv setfattr chmod chown ls stat touch Following are the operations that are not allowed on the file which are in data-split-brain state Any writes (truncate, dd, echo, cp etc) cat getfattr
