* afr: treat appending writes as stable writes.Anand Avati2013-08-131-2/+39
| | | | | | | | | | | | | Durability of appending writes is implicit in the file size. Therefore performing an explicit fsync() is unnecessary in such cases as self-heal can check for the size of file when pending changelog is not unambiguous.

* storage/posix: implement batched fsync in a single threadAnand Avati2013-07-231-0/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

The current implementation requires the filesystem to detect the storage error, after which it will notify the parent xlators and exit the glusterfsd (brick) process to prevent further troubles. The interval the health-check runs can be configured per volume with the storage.health-check-interval option. The default interval is 30 seconds. It is not trivial to write an automated test-case with the current prove-framework.

Block de-allocation is implemented via fallocate() (as requested via fuse and passed on to the brick fs) but a separate fop is created within gluster to emphasize the fact that discard changes file data (the discarded region is replaced with zeroes) and must invalidate caches where appropriate.

* dht,posix: support for case discoveryAnand Avati2013-05-251-0/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is support for discovering a filename in a given directory which has a case insensitive match of a given name. It is implemented as a virtual extended attribute on the directory where the required filename is specified in the key. E.g: sh# getfattr -e "text" -n user.glusterfs.get_real_filename:FiLe-B /mnt/samba/patchy getfattr: Removing leading '/' from absolute path names # file: mnt/samba/patchy user.glusterfs.get_real_filename:FiLe-B="file-b" In reality, there can be multiple "answers" as the backend filesystem is case sensitive and there can be multiple files which can strcasecamp() successfully. In this case we pick the first matched file from the first responding server. If a matching file does not exist, we return ENOENT (and NOT ENODATA). This way the caller can differentiate between "unsupported" glusterfs API and file not existing. This API is used by Samba VFS to perform efficient discovery of the real filename without doing a full scan at the Samba level.

* posix: fix dangerous "sharing" of fd in readdir between two requestsAnand Avati2013-04-031-2/+17
| | | | | | | | | | | | | | | | | | | | | | | posix_fill_readdir() is a multi-step function which performs many readdir() calls, and expects the directory cursor to have not "seeked away" elsewhere between two successive iterations. Usually this is not a problem as each opendir() from an application has its own backend fd, and there is nobody else to "seek away" the directory cursor. However in case of NFS's use of anonymous fd, the same fd_t is shared between all NFS readdir requests, and two readdir loops can be executing in parallel on the same dir dragging away the cursor in a chaotic manner. The fix in this patch is to lock on the fd around the loop. Another approach could be to reimplement posix_fill_readdir() with a single getdents() call, but that's for another day.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When posix-aio is enabled to perform aio fd is set with O_DIRECT whenever possible in read, writev fops. Rchecksum does not take this into account. If either offset/size/memory-buf passed to pread in rchecksum fop is not aligned, pread fails with EINVAL. Fix: Before doing pread necessary O_DIRECT manipulation is done when aio is enabled. Memory buffer passed to pread is now page-aligned. Test: 1) Create replica volume with aio enabled. 2) dd if=/dev/urandom of=a bs=1M count=1 3) kill one of the bricks in the replica pair 4) dd if=/dev/urandom of=a bs=1M count=1 5) bring back the brick. Self-heal succeeds after the change. The test above checks both rchecksum, writev fops that were changed in this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: For set/reset of outcast (ALL changelog bits set per transaction type i.e. data/mdata/entry) from afr the capability of OR/AND in xattrop is needed in posix. Otherwise marking outcast will only be possible in self-heals where appropriate locks are held so that no other transaction is in progress, so exact number can be computed with which when XATTROP_ADD happens all bits will be set for that changelog. Fix: Implemented new xattrop-op OR_ARRAY, AND_ARRAY. Made checks in __add_array to work well with __or_array. Tests: From Afr code made an OR_ARRAY with ALL bits set and it reflected on the changelog xattrs. changelog incrementing did not have any effects on the all-set changelog. From Afr code made an AND_ARRAY with 0 and it reflected in the changelog xattrs.

* cluster/stripe: implement the coalesce stripe file formatBrian Foster2012-06-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The coalesce file format for cluster/stripe condenses the striped files to a contiguous layout. The elimination of holes in striped files eliminates space wasted via local filesystem preallocation heuristics and significantly improves read performance. Coalesce mode is implemented with a new 'coalesce' xlator option, which is user-configurable and disabled by default. The format of newly created files is marked with a new 'stripe-coalesce' xattr. Cluster/stripe handles/preserves the format of files regardless of the current mode of operation (i.e., a volume can simultaneously consist of coalesced and non-coalesced files). Files without the stripe-coalesce attribute are assumed to have the traditional format to provide backward compatibility. extras/stripe-merge: support traditional and coalesce stripe formats Update the stripe-merge recovery tool to handle the traditional and coalesced file formats. The format of the file is detected automatically (and verified) via the stripe-coalesce attributes.

Then again the rename to same path is done by posix as before. The gfid-handles of the old '/d', 10 files in it are not unlinked. To prevent such problems, rename the directory to be removed to <landfill>/<gfid-str>.

| | | | | | | | | | | | | | | | | | | | | | | d_type should contain the type of the the dir-entry (man 3 readdir). Currently the d_type is always set to DT_UNKNOWN (0). The POSIX standard readdir() returns a 'struct dirent' on both Linux and NetBSD with the d_type attribute. Commit bb315cb180c3547218b5ed581d38e76aec74cf94 removed setting d_type in xlators/mount/fuse/src/fuse-bridge.c. This was using d_type_from_stat(). The stat() seems to have been removed for performance reasons. Instead of removing d_type completely, dirent->d_type could have been used. Therefore the fuse-brige can now add "fde->type = entry->d_type" back into fuse_readdir_cbk() without causing the previous performance impact.
