* posix: Reorganize posix xlator to prepare for reuse with rioShyamsundarR2017-12-0210-8338/+8830
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Split out entry and inode/fd based FOPs into separate files from posix.c 2. Split out common routines (init, fini, reconf, and such) into its own file, from posix.c 3. Retain just the method assignments in posix.c (such that posix2 for RIO can assign its own methods in the future for entry operations and such) 4. Based on the split in (1) and (2) split out posix-handle.h into 2 files, such that macros that are needed for inode ops are in one and rest are in the other If the split is done as above, posix2 can compile with its own entry ops, and hence not compile, the entry ops as split in (1) above. The split described in (4) can again help posix2 to define its own macros to make entry and inode handles, thus not impact existing POSIX xlator code. Noted problems - There are path references in certain cases where quota is used (in the xattr FOPs), and thus will fail on reuse in posix2, this needs to be handled when we get there. - posix_init does set root GFID on the brick root, and this is incorrect for posix2, again will need handling later when posix2 evolves based on this code (other init checks seem fine on current inspection) Merge of experimental branch patches with the following gerrit change-IDs > Change-Id: I965ce6dffe70a62c697f790f3438559520e0af20 > Change-Id: I089a4d9cf470c2f9c121611e8ef18dea92b2be70 > Change-Id: I2cec103f6ba8f3084443f3066bcc70b2f5ecb49a Fixes gluster/glusterfs#327 Change-Id: I0ccfa78559a7c5a68f5e861e144cf856f5c9e19c Signed-off-by: ShyamsundarR <srangana@redhat.com>
* storage/posix : options to override umaskSubha sree Mohankumar2017-12-022-12/+137
| | | | | | | | | | | | | | | | | | | | | Options "create-mask" and "create-directory-mask" are added to remove the mode bits set on a file or directory when its created. Default value of these options is 0777. Options "force-create-mode" and "force-create-directory" sets the default permission for a file or directory irrespective of the clients umask. Default value of these options is 0000. Command to set option: volume set <volume name> storage.<option-name> <value> The valid value range from 0000 to 0777.

* cluster/dht: Check for open fd only on EBADFN Balachandran2017-08-081-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | DHT fd based fops used to check if the fd was open on the cached subvol before winding the call. However, this introduced a performance regression of about 30% for reads. This check was introduced to handle cases where files were migrated while IOs were happening. As this is not the common case, dht will now check if the fd is open on the cached subvol only if the call fails with EBADF. This will prevent a performance hit where a rebalance is not running.

But we need to make sure backend size is correct on all the bricks and no crashes/manual modifications happened. Fix: At the time of get_size_version() we do 1 check to make sure size of the file is same across the bricks. From then on the FOPs will give the status of the fop, so we rely on this information to keep which bricks are good/bad.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a similar issue fixed for rename in https://review.gluster.org/#/c/16016/ For hardlinks, if cached and hashed subvolumes are different, then it will first create linkto file in hashed using root permission, but actually hardlink creation fails with EACESS and stale linkto file is never removed.All the followup hardlink calls with file name will result ESTALE because linktofile creation fails with EEXIST and follow up lookup on linkto file returns gfid-mismatching(old linkto file) and finally fails with ESTALE Steps to produce : (From link/00.t test from posix-testsuite) Steps executed in script * create a file "abc" using root * change the ownership of file to a non root user * create hardlink "link" for "abc" using a non root user, it fails with EACESS * delete "abc" * create directory "abc" using root * again try to create hadrlink "link" for "abc" using non root user, fails with ESTALE Also tried to fix other bugs in dht_linkfile_create_cbk() and posix_lookup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | stopped any volume Problem: After enabled brick mux if any volume has down and then try ot run mount with running volume , mount command is hung. Solution: After enable brick mux server has shared one data structure server_conf for all associated subvolumes.After down any subvolume in some ungraceful manner (remove brick directory) posix xlator sends GF_EVENT_CHILD_DOWN event to parent xlatros and server notify updates the child_up to false in server_conf.When client is trying to communicate with server through mount it checks conf->child_up and it is FALSE so it throws message "translator are not yet ready". From this patch updated structure server_conf to save child_up status for xlator wise. Another improtant correction from this patch is cleanup threads from server side xlators after stop the volume.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: While brick-muliplexing is on after restarting glusterd, CLI is not showing pid of all brick processes in all volumes. Solution: While brick-mux is on all local brick process communicated through one UNIX socket but as per current code (glusterd_brick_start) it is trying to communicate with separate UNIX socket for each volume which is populated based on brick-name and vol-name.Because of multiplexing design only one UNIX socket is opened so it is throwing poller error and not able to fetch correct status of brick process through cli process. To resolve the problem write a new function glusterd_set_socket_filepath_for_mux that will call by glusterd_brick_start to validate about the existence of socketpath. To avoid the continuous EPOLLERR erros in logs update socket_connect code.

* geo-rep: filter out xtime attribute during getxattrSaravanakumar Arumugam2017-04-113-8/+61
| | | | | | | | | | | | | | | | | | | | | | georep gsyncd's xtime needs to filtered irrespective of any process access. This way, we can avoid (unnecessarily)syncing xtime attribute to slave, which may raise permission denied errors. test case modified to check for xtime xattr only in backend.

* posix: use nanosecond accuracy when availableNiklas Hambüchen2017-03-071-7/+30
| | | | | | | | | | | | | | | | | | | | | | | | Programs that set mtime, such as `rsync -a`, don't work correctly on GlusterFS, because it sets the nanoseconds to 000. This creates problems for incremental backups, where files get accidentally copied again and again. For example, consider `myfile` on an ext4 system, being copied to a GlusterFS volume, with `rsync -a` and then `cp -u` in turn. You'd expect that after the first `rsync -a`, `cp -u` agrees that the file need not be copied.

This is to prevent the epoll thread from *potentially* being blocked on this lock in the worst case for extended period elsewhere in the brick stack, while the syscalls in xattrop are being performed under the same lock by a different thread. This could potentially lead to ping-timeout, if the only available epoll thread is busy waiting on the inode->lock, thereby preventing it from picking up the ping request from the client(s). Also removed some unused functions.

* posix: Fix creation of files with S_ISVTX on FreeBSDXavier Hernandez2017-02-181-3/+3
| | | | | | | | | | | | | | | | | | | On FreeBSD the S_ISVTX flag is completely ignored when creating a regular file. Since gluster needs to create files with this flag set, specialy for DHT link files, it's necessary to force the flag. This fix does this by calling fchmod() after creating a file that must have this flag set.
