* geo-rep: Fix syncing of files with non-ascii filenamesKotresh HR2018-12-261-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Creation of files/directories with non-ascii names fails to sync to the slave. It crashes with below traceback on slave. ... File "/usr/lib/x86_64-linux-gnu/glusterfs/python/syncdaemon/repce.py", line 118, in worker res = getattr(self.obj, rmeth)(*in_data[2:]) File "/usr/lib/x86_64-linux-gnu/glusterfs/python/syncdaemon/resource.py", line 709, in entry_ops [ESTALE, EINVAL, EBUSY]) File "/usr/lib/x86_64-linux-gnu/glusterfs/python/syncdaemon/syncdutils.py", line 546, in errno_wrap return call(*arg) File "/usr/lib/x86_64-linux-gnu/glusterfs/python/syncdaemon/libcxattr.py", line 83, in lsetxattr cls.raise_oserr() File "/usr/lib/x86_64-linux-gnu/glusterfs/python/syncdaemon/libcxattr.py", line 38, in raise_oserr raise OSError(errn, os.strerror(errn)) OSError: [Errno 12] Cannot allocate memory Cause: The length calculation arguments passed to blob creation was done before encoding. Hence was failing in gfid-access layer. Fix: It appears that the calculating lenght properly fixes this issue. But it will cause issues in other places in 'python2' and not in 'python3'. So encoding and decoding each required string to make geo-rep compatible with both 'python2' and 'python3' is a nightmare and is not fool proof. Hence kept 'python2' code as is with out encode/decode and applied encode/decode only to 'python3' Added non-ascii filename tests to regression Backport of: > Patch: https://review.gluster.org/21668 > BUG: 1650893 > Change-Id: I35cfaf848e07b1a0b5cb93c01b98b472f08271a6 > Signed-off-by: Kotresh HR <khiremat@redhat.com> fixes: bz#1648642 Change-Id: I35cfaf848e07b1a0b5cb93c01b98b472f08271a6 Signed-off-by: Kotresh HR <khiremat@redhat.com>
* geo-rep/hook-script: Fix ssh/scp optionsKotresh HR2018-08-031-6/+16
| | | | | | | | | | | | | | Always use ssh and scp with "-oPasswordAuthentication=no" and "-oStrictHostKeyChecking=no" options. It might hang the post script otherwise leading geo-rep setup failure Also increased geo-rep timeout. Occasionally, it's taking more time to reach Active/Passive status. Especially, the first start after create. fixes: bz#1610405 Change-Id: I9560d64dbe0edf5db73446a9fc97dda19b88d233 Signed-off-by: Kotresh HR <khiremat@redhat.com>

* tests: Enable geo-rep test casesKotresh HR2018-01-051-135/+142
| | | | | | | | | | | | | | | | | This patch re-enables the geo-rep test cases. Along with it does following optimizations. 1. Use EXPECT_WITHIN instead of sleep 2. Clean up geo-rep ssh key after test 3. Changes to gverify.sh and S56glusterd-geo-rep-create-post.sh to use the given ssh identity file for geo-rep create 4. Make gluster-command-dir configurable and introduce slave-gluster-command-dir which points the parent directory of gluster binaries in master and slave respectively.

* georep: tests for logrotate, create+rename, hard-link renameMilind Changire2016-08-091-0/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * log rotate eg. with rotate count as 2 and with the following files created x.log, x.log.1 and x.log.2, another iteration of logrotate results in the following operations to be performed x.log.2 is renamed to x.log.3 x.log.1 is renamed to x.log.2 x.log is renamed to x.log.1 x.log.3 is deleted x.log is created [possible gfid allocated that belonged to x.log.3] when a file is created, there's a big possibility that a gfid used earlier can be reassigned and reused. This causes RENAME operations to fail on slave nodes when logs are replayed, typically on a Georep restart. A function called logrotate_simulate has been added to tests/geo-rep.rc to help simulate this situation. Starting from a clean state, logrotate_simulate has to be called 4 times with a rotate count of 2 to help the logs roll over and cause a delete at the end and a gfid reallocation. With the bug-fix in place, this test should not cause the Georep session to go into a Faulty state. * create+rename On log replay after Georep restart, a create+rename causes an entry to be created for the original file, but it cannot be linked to the gfid back-end since it is associated with the renamed file before the Georep restart. A function create_rename simulates the create+rename scenario and the function create_rename_ok tests if the dangling entry is present at the slave mount. With the bug-fix in place, a dangling entry with the original name should not be found at the slave mount after logs are replayed after a Georep restart. * hard-link rename This case is similar to the create+rename case except that this is a case of renaming hard-link to one of its other names. A function hardlink_rename has been added to tests/geo-rep.rc which simulates the creation and rename of hard-link. After a Georep session restart, the test function hardlink_rename_ok should not find the source link name on the slave. With the bug-fix in place, this test should not fail. If changelogs have been enabled on the slave as well, then the logs should show an UNLINK entry for the source link name, since a rename operation of a hard link to one of its names essentially just drops the source name as per the 'mv' command semantics.

* geo-rep: Fix syncing chown in xsync crawlKotresh HR2015-11-081-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | GEO-REP INTEROP WITH SHARD FEATURE Problem: The sequence of entry creation and chown in master is recorded as creation of entry with resulted user:group in xsync changelog. During sync, entry creation is always split into two ops, MKNOD and SETATTR. Hence the issue is not being hit otherwise it would have failed with EPERM if parent is owned by different user. But with shard translator being enabled on slave, doing entry creation with MKNOD and SETATTR is not allowed, SETATTR fails as it accesses inode structure which is not linked. Solution: The sequence of entry creation and chown in master should be recorded as MKNOD and SETATTR separately always and do entry creation with single op in gfid-access xlator. The gfid-access patch will be sent separately.

* tests: New simple geo-rep regression test suiteKotresh HR2015-08-111-0/+183
This is a new simple regression test suite for geo-replication. This is written keeping in mind the run time for regression test. The existing regression test suite is rigorous one and could be run nightly. Hence the existing geo-rep tests are being removed as part of this. Also re-enable geo-rep regression with this patch. Thanks Aravinda for initial template and plan.
