Regression test portability: basic/file-snapshot.t

2014-12-03T18:13:51+00:00

- For some odd reason, setfattr(1) could fail on big-file just after
  it was created by touch(1). Add a test in between to wait for the
  file to be visible by ls(1).
- After switching to a snapshot, the file content is still in kernel
  cache, and the old content may be readen for a few seconds after
  the snapshot switch. Use ( cd $M0 && umount $M0 ) to flush vnodes
  and therefore invalidate the cache.
- Unmount the mount point at the end of the test for the cleanliness
  sake.

porting: various fixes regression tests OSX/FreeBSD

2014-08-29T16:13:02+00:00

- `wc -l` on OSX/FreeBSD adds spurious spaces, this clobbers
  up TAP output parsers - fix it.
- `umount -l` doesn't exist on OSX/FreeBSD use 'umount -f' if
   available.
- Add check for 'file' version, to handle mime type variations
  across versions
- Converge 'glusterfs --attribute-timeout=0 --entry-timeout=0'
  into '$GFS'
- Modify remaining 'mount -t nfs' to use 'mount_nfs'
- Update sha1sum for OSX to use 'openssl sha1'.

qemu-block: support readdirp

2013-09-17T18:22:01+00:00

Support the readdirp fop in qemu-block to ensure that image files
are handled correctly when readdirp is enabled. E.g., without
readdirp support, incorrect stat data for formatted files can be
reported back (and cached) via the client.

features/qemu-block: support for QCOW2 and QED formats

2013-09-03T18:26:26+00:00

This patch adds support for internals snapshots using QCOW2 and
general framework for external snapshots (next patch) with
QCOW2 and QED.

For internal snapshots, the file must be "initialized" or
"formatted" into QCOW2 format, and specify a file size.

Snapshots can be created, deleted, and applied ("goto").

e.g:

 // Format and Initialize

sh# setfattr -n trusted.glusterfs.block-format -v qcow2:10GB /mnt/imgfile
sh# ls -l /mnt/imgfile
-rw-r--r-- 1 root root 10G Jul 18 21:20 imgfile

 // Create a snapshot

sh# setfattr -n trusted.glusterfs.block-snapshot-create -v name1 imgfile

 // Apply a snapshot

sh# setfattr -n trusted.gluterfs.block-snapshot-goto -v name1 imgfile
