proper way to do defrag of a mountpoint

2010-07-14T21:44:26+00:00

Usage: "glusterfs-defrag "

there are new features added to distribute with this patch:

* bash# getfattr -n trusted.distribute.linkinfo 
  Gives output in the format ":", 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 
  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 
  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.

fop namespace cleanup.

2010-03-31T09:22:11+00:00

removed 'lock_notify', 'lock_fnotify', 'setdents', 'getdents' from
'fop' list, and removed 'stats' from mop list, as they are no more
used in the codebase, and had made code bulky/buggy.

Server backend storage hang should not cause the mount point to hang.

Submitted-by: Krishna Srinivas 
NOTE: fixed compilation issues in posix.c introduced while merging

storage/posix polls for FS/kernel being functional by issuing
statvfs() call. In case statvfs expires the timer, storage/posix will
send CHILD_DOWN to upper translator. Ultimately this will cause
protocol/server to disconnect all clients connected and also cleans up
the data structures. Hence if soft lockup or other kernel bug causes
backend FS to hang, the clients will not be hung.

storage/posix: Hand off calling close() and closedir() to the janitor thread.

2010-01-19T13:56:35+00:00

Let the janitor thread handle calling close() and closedir() on fd's and DIR *
when posix_release is called. This avoids blocking the main server loop
due to close().
