Since snapshots never change, it's safe to read from replicas for them.
A common use for this would be reading from a parent snapshot shared by
many clones.
Convert LibrbdWriteback and AioRead to use the ObjectOperation api
so we can set flags. Fortunately the external wrapper holds no data,
so its lifecycle doesn't need to be managed.
Include a simple workunit that sets the flags in various combinations
and looks for their presence in the logs from 'rbd export'.

unit tests are added in test/filestore/store_test.cc for the
FileStore::_detect_fs method, when using ext4. It tests the following
situations:
* without user_xattr, ext4 fails
* mounted with user_xattr, ext4 fails if filestore_xattr_use_omap is false
* mounted with user_xattr, ext4 succeeds if filestore_xattr_use_omap is true
The tests are grouped in an ext4 dedicated class
TEST(EXT4StoreTest, _detect_fs)
The qa/workunits/filestore/filestore.sh script is added to prepare the
environment required for the unit tests ( create an image file,
formats it with ext4 etc.). It runs ceph_test_filestore with a sudo
to allow it to mount(2) and umount(2) the ext4 file system. It is
called with
ceph_test_filestore --gtest_filter=EXT4StoreTest.*
to only run the ext4 dependent tests.
The filestore.sh script is meant to be used as part of teuthology
in order to increase the code coverage for src/os/FileStore.cc. It is
self tested and can be checked from the source directory with
CEPH_TEST_FILESTORE=../../../src/ceph_test_filestore filestore.sh TEST

A few changes, now that a few rbd problems have been fixed.
First, the more substantive changes:
- Generate a source file, and compare what's read back from rbd
devices with the content of that file.
- Write to the rbd device such that the written data spans
an (assumed 4 MB) rbd object boundary, as well as starting
and ending on non-page-aligned offsets.
- Perform multiple reads on rbd devices: entirely within a range
before any written data; beginning before but ending within
written data; the exact written data (and validating what's
read); beginning within written data but ending after it;
reading after written data but within a written rbd object;
and reading from an unwritten rbd object.
- Have the sleep between iterations provide a non-integer value
to avoid zero (or quantized) delays.
Also, some a little less substantive (but possibly informative):
- Don't run with "set -x". It produces a ton of noise that is
not useful for this test. This is an exerciser, looking
really for system crashes during concurrent activity, and
knowing which commands were (concurrently) active isn't going
to help much in diagnosis.
- Create two more directories, used to track the degree of
concurrency (more or less) and the highest rbd id consumed.
Files whose names are numbers are touched in each, and the
highest at the end is the highest during the run. This gets
around issues passing environment info from sub-shells to the
top-level shell. As a bonus, it offers a better chance of
avoiding problems due to concurrent update.
- NAMESDIR is renamed NAMES_DIR, and it (and the others) is
set up in the setup() function.
- Increase the concurrency and iteration counts.
- Move the default definitions before the ceph secrets stuff
