REVIEW: http://review.gluster.org/9106 (gluster/uss: change ctime attr of a dir when USS enabled) posted (#2) for review on master by Vijaikumar Mallikarjuna (vmallika) There are two problem mentioned in the bug description. Problem 1) If the current directory '/dir' is not a part of the snapshot say 'snap1', then the user cannot enter the '/dir/.snaps/snap1' directory. This is an expected behavior and not a bug Problem 2) Consider a testcase: mount -t nfs host1:/vol1 /mnt ls /mnt ls /mnt/.snaps (As expected this fails) gluster volume set vol1 features.uss enable Now `ls /mnt/.snaps` should work, but fails with No such file or directory. This is because NFS client and Kernel VFS caches the list of files in a directory. This cache is updated if there are any changes in the directory attributes. This problem will be fixed by patch: http://review.gluster.org/9106 COMMIT: http://review.gluster.org/9106 committed in master by Rajesh Joseph (rjoseph) ------ commit ed98d128a9413f7b8af328ca27bf4b27514d61e9 Author: vmallika <vmallika> Date: Tue Feb 2 14:34:19 2016 +0530 gluster/uss: change ctime attr of a dir when USS enabled Consider a testcase: mount -t nfs host1:/vol1 /mnt ls /mnt ls /mnt/.snaps (As expected this fails) gluster volume set vol1 features.uss enable Now `ls /mnt/.snaps` should work, but fails with No such file or directory.
