similar to: Patch to recover orphans in offline slots

In the current recovery procedure, recovering node recovers orphans from the slot it is holding and the slots that dead nodes were holding. Other online nodes recover orphans from their slots. But orphans in offline slots are left un-recovered. This patch queues recovery_completion for offline slots. Signed-off-by: Srinivas Eeda <srinivas.eeda at oracle.com> --- fs/ocfs2/journal.c | 21

The following patch is a backport of patch that recovers orphans from offline slots. It is being backported from mainline to 1.4 mainline patch: 0001-Patch-to-recover-orphans-in-offline-slots-during-rec.patch Thanks, --Srini

During recovery, a node recovers orphans in it's slot and the dead node(s). But if the dead nodes were holding orphans in offline slots, they will be left unrecovered. If the dead node is the last one to die and is holding orphans in other slots and is the first one to mount, then it only recovers it's own slot, which leaves orphans in offline slots. This patch queues complete_recovery

The following series of patches comprises the bulk of our outstanding changes for Ocfs2. Aside from the usual set of cleanups and fixes that were inappropriate for 2.6.25, there are a few highlights: The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location meshes better with modern sysfs layout. A symbolic link has been placed in the old location so as to

Next 3 patches does the following 1) movies ocfs2_slot_info struct from slot_map.c to slot_map.h 2) patch to recover orphans during mount even if the journal is clean 3) patch to recovery orphans in offline slots

Please review the list of patches being applied to the ocfs2 1.4 tree. All patches list the mainline commit hash. Thanks Sunil

Currently we only queue recovery during mount if the journal is dirty. If the last node holding orphans in other node's orphan directory dies and is the first one to mount then it only recovers its orphan directory which leaves the orphans in other nodes slots. Since the other nodes journals are clean they will not queue to recover their orphan directory. This patch queues to recover orphans

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have

On unlink, all nodes check for the dentry in dcache and if present they mark the node as unlinked. The last node that purges the inode will clean it from orphan directory. When there is a memory pressure, a dentry may not be around and hence the inode is not marked as deleted and this will lead the file to be in the orphan directory till the slot is re-used during next mount. This patch initiates

Srini, Ok, you can go ahead and cook up the background orphan cleaner. Now, we can do this in a workqueue, a thread, or a timer. I don't see why a timer doesn't work. When the timer fires, you do this: 1. Take EX on a new orphan_scan lock. 2. check the LVB for the last scan time. If it's less than the scan timeout, reset the timer for (timeout - last scan), drop the EX, and

Hi, The following patches comprise the bulk of Ocfs2 updates for the 2.6.30 merge window. Aside from larger, more involved fixes, we're adding the following features, which I will describe in the order their patches are mailed. Sunil's exported some more state to our debugfs files, and consolidated some other aspects of our debugfs infrastructure. This will further aid us in debugging
