REVIEW: http://review.gluster.org/13391 (cluster/tier: Create linkfiles to hardlinks correctly) posted (#1) for review on master by N Balachandran (nbalacha)
Steps to reproduce the issue: Create a tier volume with pure distribute hot and cold tiers of 4 bricks each. FUSE mount the volume Run the following commands (the file will be created on the hot tier): Issue 1 - file not visible on the mount --------------------------------------- [root@nb-rhs3-srv1 hardlinks]# touch file2; ln file2 hfile2; [root@nb-rhs3-srv1 hardlinks]# mv hfile2 nhfile2 [root@nb-rhs3-srv1 hardlinks]# l total 0 -rw-r--r-- 2 root root 0 Feb 6 15:11 nhfile2 Issue 2 - file listed twice on the mount ---------------------------------------- [root@nb-rhs3-srv1 hardlinks]# touch file2; ln file2 hfile2; mv file2 nfile2 ; [root@nb-rhs3-srv1 hardlinks]# l total 0 -rw-r--r-- 2 root root 0 Feb 6 16:13 hfile2 -rw-r--r-- 2 root root 0 Feb 6 16:13 nfile2 -rw-r--r-- 2 root root 0 Feb 6 16:13 nfile2 <-- duplicate listing

COMMIT: http://review.gluster.org/13391 committed in master by Dan Lambright (dlambrig) ------ commit eb362c74db84d95aac07febf0d888bd98b3fb2b9 Author: N Balachandran <nbalacha> Date: Sat Feb 6 21:09:29 2016 +0530 cluster/tier: Create linkfiles to hardlinks correctly There is a bug in the way hardlinks are handled in tiered volumes. Ideally, the tier linkto files on the cold tier to files that are hardlinks to each other on the hot tier, should themselves be hardlinks of each other. As they are not, they end up being files with the same gfid but different names for the cold tier dht, and end up overwriting the cached-subvol information stored in the dht inode-ctx.
