* storage/posix: implement batched fsync in a single threadAnand Avati2013-07-235-1/+288
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because of the extra fsync()s issued by AFR transaction, they could potentially "clog" all the io-threads denying unrelated operations from making progress. This patch assigns a dedicated thread to issues fsyncs, as an experimental feature to understand performance characteristics with the approach. As a basis, incoming individual fsync requests are grouped into batches, falling in the same @batch-fsync-delay-usec window of time. These windows can extend in practice, as processing of the previous batch can take longer than @batch-fsync-delay-usec while new requests are getting batched. The feature support three modes (similar to the -S modes of fs_mark) - syncfs: In this mode one syncfs() is issued per batch, instead of N fsync()s (one per file.) - syncfs-single-fsync: In this mode one syncfs() is issued per batch (which, on Linux, guarantees the completion of write-out of dirty pages in the filesystem up to that point) and one single fsync() to synchronize or flush the controller/drive cache. This corresponds to -S 2 of fsmark. - syncfs-reverse-fsync: In this mode, one syncfs() is issued per batch, and all the open files in that batch are fsync()'ed in the reverse order of the queue. This corresponds to -S 4 of fsmark. - reverse-fsync: In this mode, no syncfs() is issued and all the files in the batch are fsync()'ed in the reverse order. This corresponds to -S 3 of fsmark.

* features/changelog: changelog translatorAvra Sengupta2013-07-2235-16/+5053
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the initial version of the Changelog Translator. What is it ----------- Goal is to capture changes performed on a GlusterFS volume. The translator needs to be loaded on the server (bricks) and captures changes in a plain text file inside a configured directory path (controlled by "changelog-dir", should be somewhere in <export>/.glusterfs/changelog by default). Changes are classified into 3 types: - Data: : TYPE-I - Metadata : TYPE-II - Entry : TYPE-III Changelog file is rolled over after a certain time interval (defauls to 60 seconds) after which a changelog is started. The thing to be noted here is that for a time interval (time slice) multiple changes for an inode are recorded only once (ie. say for 100+ writes on an inode that happens within the time slice has only a single corresponding entry in the changelog file). That way we do not bloat up the changelog and also save lots of writes. Changelog Format ----------------- TYPE-I and TYPE-II changes have the gfid on the entity on which the operation happened. TYPE-III being a entry op requires the parent gfid and the basename. Changelog format has been kept to a minimal and it's upto the consumers to do the heavy loading of figuring out deletes, renames etc.. A single changelog file records all three types of changes, with each change starting with an identifier ("D": DATA, "M": METADATA and "E": ENTRY). Option is provided for the encoding type (See TUNABLES). Consumers ---------- The only consumer as of today would be geo-replication, although backup utilities, self-heal, bit-rot detection could be possible consumers in the future. CLI ---- By default, change-logging is disabled (the translator is present in the server graph but does nothing). When enabled (via cli) each brick starts to log the changes. There are a set of tunable that can be used to change the translators behaviour: - enable/disable changelog (disabled by default) gluster volume set <volume> changelog {on|off} - set the logging directory (<brick>/.glusterfs/changelogs is the default) gluster volume set <volume> changelog-dir /path/to/dir - select encoding type (binary (default) or ascii) gluster volume set <volume> encoding {binary|ascii} - change the rollover time for the logs (60 secs by default) gluster volume set <volume> rollover-time <secs> - when secs > 0, changelog file is not open()'d with O_SYNC flag - and fsync is trigerred periodically every <secs> seconds. gluster volume set <volume> fsync-interval <secs> features/changelog: changelog consumer library (libgfchangelog) A shared library is provided for the consumer of the changelogs for easy acess via APIs. Application can link against this library and request for changelog updates. Conversion of binary logs to human-readable ascii format is also taken care by the library which keeps a copy of the changelog in application provided working directory.

For eg., if the gfid of a file is f3142503-c75e-45b1-b92a-463cf4c01f99, that file can be accessed using <gluster-mount>/.gfid/f3142503-c75e-45b1-b92a-463cf4c01f99 .gfid is a virtual directory used to seperate out the namespace for accessing files through gfid. This way, we do not conflict with filenames which can be qualified as uuids. * A new file/directory/symlink can be created with a pre-specified gfid. A setxattr done on parent directory with fuse_auxgfid_newfile_args_t initialized with appropriate fields as value to key "glusterfs.gfid.newfile" results in the entry <parent>/bname whose gfid is set to args.gfid. The contents of the structure should be in network byte order. struct auxfuse_symlink_in { char linkpath[]; /* linkpath is a null terminated string */ } __attribute__ ((__packed__)); struct auxfuse_mknod_in { unsigned int mode; unsigned int rdev; unsigned int umask; } __attribute__ ((__packed__)); struct auxfuse_mkdir_in { unsigned int mode; unsigned int umask; } __attribute__ ((__packed__)); typedef struct { unsigned int uid; unsigned int gid; char gfid[UUID_CANONICAL_FORM_LEN + 1]; /* a null terminated gfid string * in canonical form. */ unsigned int st_mode; char bname[]; /* bname is a null terminated string */ union { struct auxfuse_mkdir_in mkdir; struct auxfuse_mknod_in mknod; struct auxfuse_symlink_in symlink; } __attribute__ ((__packed__)) args; } __attribute__ ((__packed__)) fuse_auxgfid_newfile_args_t; An initial consumer of this feature would be geo-replication to create files on slave mount with same gfids as that on master. It will also help gsyncd to access files directly through their gfids. gsyncd in its newer version will be consuming a changelog (of master) containing operations on gfids and sync corresponding files to slave. * Also, bring in support to heal gfids with a specific value. fuse-bridge sends across a gfid during a lookup, which storage translators assign to an inode (file/directory etc) if there is no gfid associated it. This patch brings in support to specify that gfid value from an application, instead of relying on random gfid generated by fuse-bridge. gfids can be healed through setxattr interface. setxattr should be done on parent directory. The key used is "glusterfs.gfid.heal" and the value should be the following structure whose contents should be in network byte order. typedef struct { char gfid[UUID_CANONICAL_FORM_LEN + 1]; /* a null terminated gfid * string in canonical form */ char bname[]; /* a null terminated basename */ } __attribute__((__packed__)) fuse_auxgfid_heal_args_t; This feature can be used for upgrading older geo-rep setups where gfids of files are different on master and slave to newer setups where they should be same. One can delete gfids on slave using setxattr -x and .glusterfs and issue stat on all the files with gfids from master.

* mount/fuse: unlink the inode on revalidate if entry not foundBrian Foster2013-07-182-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | If an inode/dentry is linked via a client and removed via a separate client, the inode/dentry mapping in the initial client remains. A lookup of the removed name on the initial client typically returns ENOENT once the associated caches expire. If the initial client has multiple dentries linked to the same inode, however, lookups on the non-removed dentry create windows of time where lookups on the stale/removed name return successfully. This occurs because the stale mapping resolves to the still valid inode and tricks md-cache into returning valid lookup data. To correct this situation, unlink the stale inode mapping on a failed (ENOENT) revalidation lookup (i.e., when fuse has resolved the inode but a lookup returns ENOENT). Note that with this change, the state still occurs until an md-cache window has expired, allowed a lookup to pass through to the server and given the fuse translator an opportunity to clean up.

Why is this required: - stime means 'slave xtime', mainly used to keep track of slave node's sync status when distributed geo-replication is used. Logic of calculating 'min()' for this stime is very important as in case of crashes/reboots/shutdown, we will have to 'restart' with crawling from stime time value from the mount point, which gives the 'min()' of all the bricks, which means, we don't miss syncing any files in the above cases.
