NFS is picking up geo-rep's already open (read-only) file descriptor

2013-07-05T13:31:14+00:00

Add anonymous member to fd_t and use it instead of over-loading pid for
geo-rep and self heal

storage/posix: return -1 if lstat call returns non zero value apart from -1

2012-10-12T01:08:20+00:00

* If lstat() call in posix_{pstat, istat} returns non zero return value
  other than -1, then treat lstat() call to have been failed and return -1
  itself. This might happen if there is some bug in the backend filesystem.

storage/posix: Option to set brick(of a volume)'s root dir's uid/gid

2012-09-14T08:29:27+00:00

CLI
---
gluster volume set VOLNAME owner-uid uid
gluster volume set VOLNAME owner-gid gid
where uid,gid are the owner's user id and group id respectively that
would be set on the root of all brick (backend) fs.

TODO: uid/gid should not be -1. Today we don't validate that in CLI.

cluster/dht: Optimize readdirp calls in DHT

2012-08-17T05:25:17+00:00

Bring in option which is supported by posix xlator
to filter out directory's entries from being returned.
DHT would now request non-first subvols to filter out
directory entries.

dht xlator-option readdir-optimize will enable this
optimization

storage/posix: handle getxattr failures gracefully

2012-07-18T08:10:44+00:00

Use proper variable types for getting return value of getxattr calls,
which otherwise can lead to segfaulting of processes or page allocation
failures in the kernel.

cluster/stripe: implement the coalesce stripe file format

2012-07-16T04:39:39+00:00

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.
