Steps to Reproduce: 1. Create ganesha cluster and create 2*(4+2) EC volume. 2. Enable nfs-ganesha on the volume with mdcache settings. 3. Mount the volume. 4. Create a file and write contents to it. 5. Create hard link to that file. 6. Read the contents of the file. Actual results: Contents of original file are not seen when hardlink is created Expected results: Contents should not get removed Additional info: [root@dhcp47-49 ec_test]# echo "testfile" > test1 [root@dhcp47-49 ec_test]# cat test1 testfile [root@dhcp47-49 ec_test]# ls -lhrtia test1 10548474259765385418 -rw-r--r--. 1 root root 9 Dec 27 20:38 test1 [root@dhcp47-49 ec_test]# ln test1 test1_hlink [root@dhcp47-49 ec_test]# ls -lhrtia test1 test1_hlink 10548474259765385418 -rw-r--r--. 2 root root 0 Dec 27 20:38 test1_hlink 10548474259765385418 -rw-r--r--. 2 root root 0 Dec 27 20:38 test1 [root@dhcp47-49 ec_test]# cat test1 [root@dhcp47-49 ec_test]# cat test1_hlink [root@dhcp47-49 ec_test]# [root@dhcp47-49 ec_test]# [root@dhcp47-49 ec_test]# cat test1 [root@dhcp47-49 ec_test]# cat test1_hlink [root@dhcp47-49 ec_test]# cat test1 [root@dhcp47-49 ec_test]# cat test1
