* synctask: minor enhancementsAnand Avati2013-08-281-4/+1
| | | | | | | | | | | | | | | | | | | | | | | - Enhance syncenv_new() to accept scaling parameters of syncproc. Previously the scaling parameters were hardcoded and decided at compile time. - New API synctask_create() which returns the created synctask. This is similar to synctask_new which only returned the status of whether a synctask could be created or not. The meaning of NULL cbk in synctask_create() means the task is "joinable". Until synctask_join() is called on such a synctask, the task is not reaped and resources are not destroyed. The task would be in a zombie state after synctask_fn returns and before synctask_join() is called.

* cluster/afr: Let two data-self-heals compete in new domainPranith Kumar K2013-07-031-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: At the moment data-self-heal acquires locks in following pattern. It takes full file lock then gets xattrs on files on both replicas. Decides sources/sinks based on the xattrs. Now it acquires lock from 0-128k then unlocks the full file lock. Syncs 0-128k range from source to sink now acquires lock 128k+1 till 256k then unlocks 0-128k, syncs 128k+1 till 256k block... so on finally it takes full file lock again then unlocks the final small range block. It decrements pending counts and then unlocks the full file lock. This pattern of locks is chosen to avoid more than 1 self-heal to be in progress. BUT if another self-heal tries to take a full file lock while a self-heal is already in progress it will be put in blocked queue, further inodelks from writes by the application will also be put in blocked queue because of the way locks xlator grants inodelks. So until the self-heal is complete writes are blocked. Here is the code: xlators/features/locks/src/inodelk.c - line 225 if (__blocked_lock_conflict (dom, lock) && !(__owner_has_lock (dom, lock))) { ret = -EAGAIN; if (can_block == 0) goto out; gettimeofday (&lock->blkd_time, NULL); list_add_tail (&lock->blocked_locks, &dom->blocked_inodelks); } This leads to hangs in applications. Fix: Since we want to prevent two parallel self-heals. We let them compete in a separate "domain". Lets call the domain on which the locks have been taken on in previous approach as "data-domain". In the new approach When a self-heal is triggered, it acquires a full lock in the new domain "self-heal-domain". After this it performs data-self-heal using the locks in "data-domain" as before. unlock the full file lock in "self-heal-domain" With this approach, application's writevs don't have to wait in pending queue when more than 1 self-heal is triggered.

* pump: Set self-heal readdir size in pumpPranith Kumar K2013-04-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In Pump entry self-heal happens for each directory during the first opendir using conservative merge. But in entry-self-heal readdir is issued with '0' size. So entry self-heal is not creating any files. After pump thinks entry self-heal is complete it proceeds to heal each of the file in the directory it just healed. Fortunately most of the times it chooses source-brick in pump as read-child for readdir. This happens because readchild is the subvolume on which lookup succeeds first. In pump lookup succeeds faster in local process than on the destination brick process most of the times. For all the entries pump finds in readdir it does a lookup. During this lookup the entry on the destination brick is created and healed. This is the reason why replace-brick succeeds whenever read-child for the directory is chosen as the source-brick. Which is most of the times. When read-child is chosen as the destination brick, readdir returns no entries so replace-brick completes without syncing the whole data. Fix: Set readdir-size in pump so that entry self-heal happens with 64k size. This ensures that entry self-heal triggered from opendir actually creates the files on the destination brick.

* cluster/afr: Make data selfheal trigger to be configurable.Pranith Kumar K2011-09-081-1/+1
| | | | | | | | | | | | | | | | | | | | By default, lookup triggers data self-heal but that is not the preferred way of operating replicated volumes. We would like the data self heals to be triggered in open instead. Number of back-ground self-heals allowed is 16 and lookups block until self-heal is completed. We want to prevent blocking in fops. We can not make lookups independent of self-heal frames because when there are gfid conflicts the decision of which file is correct is determined in self-heal phase. So in afr, lookup self-heal is going to guarantee name space consistency and open/fd fops will take responsibility for data consistency, these are non blocking. The user needs to set the option cluster.data-self-heal "open" for this behavior.

* PUMP: perform opendir on pump xlator instead of its childPranith K2011-06-161-4/+2
| | | | | | | | | | | | | | | | | | | | | | When replace-brick is performed, there is a high probability for the directories on the source brick to not have any pending entry xattrs. So for proper self-heal we need the force merge to kick in. If the opendir is performed on pump xlator directory is examined and if the entries on its children do not match then force merge is triggered, so missing entries will be created on the sink. Pending xattrs are set from source to sink on the files present on source in this process. So when the lookup happens the self-heal is triggered. Before this fix, the code is working because the self-heal source is decided based on what file is biggest in size which is a wrong and removed.
