* snapshot: append timestamp with snapnameMohammed Rafi KC2015-03-101-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Appending GMT time stamp with snapname by default. If no-timestamp flag is given during snapshot creation, then time stamp will not append with snapname; Initial consumer of this feature is Samba's Shadow Copy feature. This feature allows Windows user to get previous revisions of a file. For this feature to work snapshot names under .snaps folder (USS) should have timestamp in following format appended: @GMT-YYYY.MM.DD-hh.mm.ss PS: https://www.samba.org/samba/docs/man/manpages/vfs_shadow_copy2.8.html This format is configurable by Samba conf file. Due to a limitation in Windows directory access the exact format cannot be used by USS. Therefore we have modified the file format to: _GMT-YYYY.MM.DD-hh.mm.ss Snapshot scheduling feature also required to append timestamp to the snapshot name therefore timestamp is appended in snapshot creation itself instead of doing the changes in snapview server.

* features/snapview-server: check if the reference to the snapshot world isRaghavendra Bhat2014-10-281-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | correct before doing any fop The following operations might lead to problems: * Create a file on the glusterfs mount point * Create a snapshot (say "snap1") * Access the contents of the snapshot * Delete the file from the mount point * Delete the snapshot "snap1" * Create a new snapshot "snap1" Now accessing the new snapshot "snap1" gives problems. Because the inode and dentry created for snap1 would not be deleted upon the deletion of the snapshot (as deletion of snapshot is a gluster cli operation, not a fop). So next time upon creation of a new snap with same name, the previous inode and dentry itself will be used. But the inode context contains old information about the glfs_t instance and the handle in the gfapi world. Directly accessing them without proper check leads to ENOTCONN errors. Thus the glfs_t instance should be checked before accessing. If its wrong, then right instance should be obtained by doing the lookup.

* snapview-server: get the handle if its absent before doing any fopRaghavendra Bhat2014-09-121-5/+17
| | | | | | | | | | | | | | | | | | | | | | | * Now that NFS server does inode linking in readdirp, it can resolve the gfid (i.e. find the right inode from its inode table) present in the filehandle sent by the NFS client on which a fop came. So instead of sending the lookup on that entry, it directly sends the fop. But snapview-server does not get the handle for the entries in readdirp (because doing a lookup on each entry via gfapi would be costly. So it waits till a lookup is done on that inode, to get the handle and the fs instance and fill it in the inode context). So when NFS resoves the gfid and directly sends the fop, snapview-server will not be able to perform the fop as the inode contet would not contain the fs instance and the handle. So fops should check for the handle before doing gfapi calls. If the handle and fs instance are not present in the inode context they should get them by doing an explicit lookup on the entry.

* Regression test portability: mountEmmanuel Dreyfus2014-08-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Address various portability-related problems related to mount - In order to address the non-portability of NFS mount options, use the mount_nfs shell function everywhere, and use it to translate options. - Make sure NFS mounts are unmounted before shutting down the daemons in order to avoid deadlock. The change is done in every test that did not unmounted NFS mounts at the end of the script, and in global cleanup function as well. The force_umount shell function from volume.rc was duplicated as umount_nfs in nfs.rc so that we do not have to add an include on volume.rc for all NFS tests that do not need it. - The FUSE mount type on NetBSD is puffs|perfuse|fuse.glusterfs instead of just fuse.glusterfs, make the regexp configurable in include.rc - Finding wether the mount is RO or RW in mount output needs a system-dependent command configurable in include.rc - mount options in /proc/mounts may be limited to "rw", adjust the regexp for this case where there is no comma And while there change rm into rm -f in tests/basic/mount.t for removal opearation that should fail, since rm may ask for confirmation Change-Id: I1fb708486ec350b2885e2404879561c1020fa8fd BUG: 1129939 Signed-off-by: Emmanuel Dreyfus <manu@netbsd.org> Reviewed-on: http://review.gluster.org/8494 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Harshavardhana <harsha@harshavardhana.net> Tested-by: Harshavardhana <harsha@harshavardhana.net>
* make snapview-server more compatible with NFS serverRaghavendra Bhat2014-07-161-25/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * There was no handle based API for listxattr. With this change, glfs_h_getxattrs also handles the listxattr functionality by checking whether the name is NULL or not (like posix). But all the gfapi functions for listxattr (glfs_h_getxattrs AND glfs_listxattr AND glfs_flistxattr) returns the names of the xattrs in a buffer provided by the caller. But snapview-server has to return the list of xattrs in a dict itself (similar to posix xlator). But the buffer just contains the names of the xattrs. So for each xattr, a zero byte value is set (i.e. "") into the dict and sent back. Translators which do xattr caching (as of now md-cache which caches selinux and acl related xattrs) should not cache those xattrs whose value is a zero byte data (""). So made changes in md-cache to ignore zero byte values. * NFS server was not linking the inodes to inode table in readdirp. This was leading to applications getting errors. The below set of operations would lead to applications getting error 1) ls -l in one of the snaopshots (snapview-server would generate gfids for each entry on the fly and link the inodes associated with those entries) 2) NFS server upon getting readdirp reply would not link the inodes of the entries. But it used to generate filehandles for each entry and associate the gfid of that entry with the filehandle and send it as part of the reply to nfs client. 3) NFS client would send the filehandle of one of those entries when some activity is done on it. 4) NFS server would not be able to find the inode for the gfid present in the filehandle (as the inode was not linked) and would go for hard resolution by sending a lookup on the gfid by creating a new inode. 5) snapview-client will not able to identify whether the inode is a real inode existing in the main volume or a virtual inode existing in the snapshots as there would not be any inode context. 6) Since the gfid upon which lookup is sent is a virtual gfid which is not present in the disk, lookup would fail and the application would get an error. To handle above situation, now nfs server also does inode linking in readdirp.
