* proper way to do defrag of a mountpointAmar Tumballi2010-07-145-30/+257
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Usage: "glusterfs-defrag <MOUNTPOINT>" there are new features added to distribute with this patch: * bash# getfattr -n trusted.distribute.linkinfo <file> Gives output in the format "<hostname>:<directory>", if there is a linkfile present, where hostname is server, directory is backend directory where the actual linkfile is present. * bash# getfattr -n trusted.glusterfs.pathinfo <path> Gives layout information if directory, and info about actual location of file in backend servers, in the form of 'hostname:directory'. (TODO: should extend it to all xlators) * bash# getfattr -n trusted.distribute.fix.layout <path> scales out the directory layout in distribute, so when new servers are added, layouts are fixed to include them. * removed 'scale-n-defrag.sh' as its no more required. * changed 'defrag.sh' to have a feature to specify target bricks, so defrag happens to only those nodes. moved the file to 'glusterfs-defrag', which now gets installed to '${prefix}/bin' * storage/posix: takes new option 'hostname' so it can resolve to same hostname given during 'gluster volume create'. with 'trusted.glusterfs.pathinfo' posix returns the value in 'hostname:real_path' format.

* nfs: Support directory level exportsShehjar Tikoo2010-07-047-49/+712
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nfsx has followed traditional approach of exporting whole volumes as NFS exports. The Platform requires and some users have approached us for introducing exports of only specific directories instead of full Gluster volumes. This commit introduces this support through two nfsx options: Option 1: ========= option nfs3.<volume-name>.export-dir <subdir1-in-vol>,<subdir2-in-vol>,..<subdirN-in-vol> export-dir will allow the export of a particular dir as a single export by itself. For eg.: volume posix type storage/posix option directory /export/ end-volume volume posix-ac type features/access-control subvolumes posix end-volume volume nfs type nfs/server subvolumes posix-ac option rpc-auth.addr.allow * option nfs3.posix-ac.export-dir /homes/shehjart end-volume A comma separate list of sub-directories will set up those dirs as separated exports. At the nfs client, the mount command will be: $ mount <nfsserver>:/posix-ac/homes/shehjart /mnt Option 2: ========= option nfs3.<volume-name>.export-volumes <on|off> There can be situations where users only want the directory level exports and require that volume exports be completely disabled. The above option allows us to do this. By default, volume exports are enabled. From the earlier example, replacing <volume-name> with posix-ac, will disable mounting of the posix-ac volume as a whole. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.

* performance/write-behind: explicitly enforce ordering of overlapping writes.Raghavendra G2010-07-021-173/+279
| | | | | | | | | | | | | | | | | - If there are non-contiguous offsets (offsets which do not start where previous write ended), wait for completion of previous writes to server, before sending new ones. - Send flush call to server only when all writes are completed. - If a file is opened with O_APPEND, at any point of time a maximum only one write call to server should be in transit. This is to avoid reordering of writes in the presence of afr which can result in data corruption. See bug #934 for more details.

| | | | | | | | | | | | | | | | When a lookup request comes in for (rootfh, ".."), we need to handle it in a way that returns the attributes and handle of the root dir. Not doing so crashes nfsx because the inode table is not able to find a inode for the root's parent. This inode was being referenced in nfs3_lookup_parentdir_resume when filling a loc for the lookup fop. For the record, such a lookup request is sent by vmkernel.

* nfs3: Funge . and .. ino/gen in readdir of rootShehjar Tikoo2010-06-013-39/+96
| | | | | | | | | | | | | | | | | In the readdir reply for the root of the export, replace the ino and gen number for the . and .. entries with 1 and 0 respectively. On clients which inspect this field, the client will error out due to the change in inode number of the root directory when see for "." .. also needs to be replaced because we do not have a concept of the parent directory of root. The return of 1 and 0 is the same as the behaviour of: stat /.. command. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.
