glusterfs.git/tests/basic/afr/tarissue.t, branch v3.12.5 GlusterFS is a distributed file-system capable of scaling to several petabytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. tests: Add afr/tarissue.t to bad tests 2016-05-21T01:23:05+00:00 Ravishankar N ravishankar@redhat.com 2016-05-20T05:49:27+00:00 beebee772505017ed1ef24197880e1ccd0a2536c Likey a tar binary bug and nothing to do with gluster but adding to bad tests for now.

cluster/afr: Don't let NFS cache stat after writes 2016-05-05T01:42:14+00:00 Pranith Kumar K pkarampu@redhat.com 2016-03-19T06:10:26+00:00 4c4624c9bad2edf27128cb122c64f15d7d63bbc8 Problem: Afr does post-ops after write but the stat buffer it unwinds is at the time of write, so if nfs client caches this, it will see different ctime when it does stat on it after post-op is done. From NFS client's perspective it thinks the file is changed. Tar which depends on this to be correct keeps giving 'file changed as we read it' warning. If Afr instead has to choose to unwind after post-op, eager-lock, delayed-post-op will have to be disabled which will lead to bad performance for all write usecases. Fix: Don't let client cache stat after write.

Problem:
Afr does post-ops after write but the stat buffer it unwinds is at the
time of write, so if nfs client caches this, it will see different
ctime when it does stat on it after post-op is done. From NFS client's
perspective it thinks the file is changed. Tar which depends on this
to be correct keeps giving 'file changed as we read it' warning.
If Afr instead has to choose to unwind after post-op, eager-lock,
delayed-post-op will have to be disabled which will lead to bad
performance for all write usecases.

Fix:
Don't let client cache stat after write.
