tests: use trap mechanism to ensure that proper cleanups happen

2016-04-12T12:04:24+00:00

This actually consists of several parts.

  * Added a generic cleanup-scheduling mechanism.  Instead of calling
    "trap ... EXIT" directly, just call "push_trapfunc ..." instead and
    your cleanup function will be called along with any others.

  * Converted a few tests to use push_trapfunc.

  * Added "push_trapfunc cleanup_lvm" to snapshot.rc to address the
    particular problem that's driving this - snapshot tests not calling
    cleanup_lvm on their own and leaving bad state for the next test.

cluster/ec: Fix invalid config check for directories

2016-03-01T07:56:41+00:00

The trusted.ec.config xattr is not defined for directories. However
sometimes it could be requested because the inode type of a directory
can temporarily be IA_INVAL.

Requesting such xattr using the xattrop fop when it doesn't exist,
returns a config value full of 0's, which is invalid and caused some
fops to fail.

This patch filters out this case by ignoring config xattr == 0.

cluster/ec: Automate heal for replace brick

2016-02-09T07:20:43+00:00

Problem:
After a replace brick command, newly added
brick does not contain data which existed
on old brick.

Solution:
Do getxattr after initialization of all the
bricks. This will trigger heal for brick root
as soon as it finds the version mismatch on
newly added brick.

Removing tests from ec-new-entry.t which were
required to simulate automation of heal after
replace brick.

storage/posix: Implement .unlink directory

2015-12-15T08:35:59+00:00

Problem: For EC volume, If a file descriptor is open and
file has been unlinked, any further write on that fd will
fail. When a write request comes, EC internally reads some
blocks using anonymous fd. This read will fail as the file
has already been unlinked.

Solution: To solve this issue, we are using .unlink directory
to keep track of unlinked file. If a file is to be unlinked
while its fd is open, move this to .unlink directory and unlink
it from .glusterfs and real path. Once all the fd will be closed,
remove this entry form .unlink directory.

bricks to be considered for reading.

Problem :
When a new entry is created dirty mark xattrs are not
created this will need full heal to be performed, even
when there are partial failures.

Solution :
Marks new entry changelog in self-heal.

PS: Also fixed erasing of dirty markers when no data heal
is required.

ec : trusted.ec.version xattr of all root directories of all bricks should be same.

2015-08-29T10:31:58+00:00

Problem:
After replacing the brick using "replace-brick" command and running "heal
full", the version of the root directory of the newly added brick is not
getting healed. heal starts running on the dentries of the root but does not
run on root directory.

Solution:
Run heal on root directory.
