* GFS2: Fix permissions on "recover" fileSteven Whitehouse2009-08-14
| | | | | | | | | | | Although this file is only ever written and not read by userspace, it seems that the utils are opening this file O_RDWR, so we need to allow that. Also fixes the whitespace which seemed to be broken. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com> Cc: David Teigland <teigland@redhat.com>
* GFS2: remove dcache entries for remote deleted inodesBenjamin Marzinski2009-07-30
| | | | | | | | | | | | | When a file is deleted from a gfs2 filesystem on one node, a dcache entry for it may still exist on other nodes in the cluster. If this happens, gfs2 will be unable to free this file on disk. Because of this, it's possible to have a gfs2 filesystem with no files on it and no free space. With this patch, when a node receives a callback notifying it that the file is being deleted on another node, it schedules a new workqueue thread to remove the file's dcache entry.

* GFS2: Fix incorrent statfs consistency checkBenjamin Marzinski2009-07-30
| | | | | | | | | | | Since both linked and unlinked inodes are counted by rgd->rd_dinodes, It makes no sense to count them with the used data blocks (first check that I changed), it makes sense to count them with the linked inodes (second check), and it makes no sense to care if there are more unlinked inodes than linked ones. This fixes these errors. Signed-off-by: Benjamin Marzinski <bmarzins@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* GFS2: Don't put unlikely reclaim candidates on the reclaim list.Benjamin Marzinski2009-07-30
| | | | | | | | | | | GFS2 was placing far too many glocks on the reclaim list that were not good candidates for freeing up from cache. These locks would sit there and repeatedly get scanned to see if they could be reclaimed, wasting a lot of time when there was memory pressure. This fix does more checks on the locks to see if they are actually likely to be removable from cache.

* GFS2: Don't try and dealloc own inodeSteven Whitehouse2009-07-30
| | | | | | | | | | When searching for unlinked, but still allocated inodes during block allocation, avoid the block relating to the inode that is doing the allocation. This fixes a hang caused when an unlinked, but still open, inode tries to allocate some more blocks and lands up finding itself during the search for deallocatable inodes.

* GFS2: Fix panic in glock memory shrinkerBenjamin Marzinski2009-07-30
| | | | | | | | | | | | | | | | It is possible for gfs2_shrink_glock_memory() to check a glock for demotion that's in the process of being freed by gfs2_glock_put(). In this case, gfs2_shrink_glock_memory() will acquire a new reference to this glock, and then try to free the glock itself when it drops the refernce. To solve this, gfs2_shrink_glock_memory() just needs to check if the glock is in the process of being freed, and if so skip it without ever unlocking the lru_lock.

* GFS2: keep statfs info in sync on growsBenjamin Marzinski2009-07-30
| | | | | | | | | | | | | | | | | | | GFS2 wasn't syncing its statfs info on grows. This causes a problem when you grow the filesystem on multiple nodes. GFS2 would calculate the new space based on the resource groups (which are always current), and then assume that the filesystem had grown the from the existing statfs size. If you grew the filesystem on two different nodes in a short time, the second node wouldn't see the statfs size change from the first node, and would assume that it was grown by a larger amount than it was. When all these changes were synced out, the total fileystem size would be incorrect (the first grow would be counted twice). This patch syncs makes GFS2 read in the statfs changes from disk before a grow, and write them out after the grow, while the master statfs inode is locked.

* GFS2: Shrink the shrinkerSteven Whitehouse2009-07-30
| | | | | | | | | | This patch removes some of the special cases that the shrinker was trying to deal with. As a result we leave fewer items on the list and none at all which cannot be demoted. This makes the list scanning more efficient and solves some issues seen with large numbers of inodes. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

* GFS2: Add tracepointsSteven Whitehouse2009-06-12
| | | | | | | | | | | This patch adds the ability to trace various aspects of the GFS2 filesystem. The trace points are divided into three groups, glocks, logging and bmap. These points have been chosen because they allow inspection of the major internal functions of GFS2 and they are also generic enough that they are unlikely to need any major changes as the filesystem evolves.

* push BKL down into ->put_superChristoph Hellwig2009-06-11
| | | | | | | | | | | | | | | | | Move BKL into ->put_super from the only caller. A couple of filesystems had trivial enough ->put_super (only kfree and NULLing of s_fs_info + stuff in there) to not get any locking: coda, cramfs, efs, hugetlbfs, omfs, qnx4, shmem, all others got the full treatment. Most of them probably don't need it, but I'd rather sort that out individually. Preferably after all the other BKL pushdowns in that area.

| * block: Do away with the notion of hardsect_sizeMartin K. Petersen2009-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by: Martin K.

* | GFS2: Remove args subdir from gfs2 sysfs filesSteven Whitehouse2009-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we can cat /proc/mounts there is no need to have this subdirectory in the gfs2 sysfs files. In fact this does not reflect the full range of possible mount argumenmts, where as /proc/mounts does. There was only one userland user of this set of sysfs files and it will function perfectly well without these files being present (in fact that subcommand of gfs2_tool is obsolete anyway). The tune/* subdirectory is also considered mostly obsolete, but there are a few uses of this until mount arguments can be added for the last few functions for which there are no equivalents currently. However the tune/* directory is still in my sights and new code should avoid using it. Only the gfs2_quota and gfs2_tool programs are know to use tune/* at the moment.

| | | | | | | | | | | | | | | | | | | | | | This patch increases the frequency with which gfs2 looks for unlinked, but still allocated inodes.

* | GFS2: Add a rgrp bitmap full flagSteven Whitehouse2009-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During block allocation, it is useful to know if sections of disk are full on a finer grained basis than a single resource group. This can make a performance difference when resource groups have larger numbers of bitmap blocks, since we no longer have to search them all block by block in each individual bitmap. The full flag is set on a per-bitmap basis when it has been searched and found to have no free space. It is then skipped in subsequent searches until the flag is reset. The resetting occurs if we have to drop the glock on the resource group for any reason, or if we deallocate some blocks within that resource group and thus free up some space.

* | GFS2: Improve resource group error handlingSteven Whitehouse2009-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the error handling in the case where we discover that the summary information in the resource group doesn't match the bitmap information while in the process of allocating blocks. Originally this resulted in a kernel bug, but this patch changes that so that we return -EIO and print some messages explaining what went wrong, and how to fix it. We also remember locally not to try and allocate from the same rgrp again, so that a subsequent allocation in a different rgrp should succeed. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

* | GFS2: Umount recovery race fixSteven Whitehouse2009-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a race condition where we can receive recovery requests part way through processing a umount. This was causing problems since the recovery thread had already gone away. Looking in more detail at the recovery code, it was really trying to implement a slight variation on a work queue, and that happens to align nicely with the recently introduced slow-work subsystem. As a result I've updated the code to use slow-work, rather than its own home grown variety of work queue. When using the wait_on_bit() function, I noticed that the wait function that was supplied as an argument was appearing in the WCHAN field, so I've updated the function names in order to produce more meaningful output.

| | | | | | | | | | | | | | | | | | | | | | For some reason GFS2 has been missing support for non-linear mappings. This patch fixes that, and also avoids taking any locks for mmap in the O_NOATIME case. In fact we don't actually need to take the lock here at all - just doing file_accessed() would be enough, but we have to take the lock eventually and this helps it hit disk (and thus be seen by other nodes) faster.

Also, the generic function was checking for a number of corner cases which cannot happen on the metadata address spaces so that this should be faster too.

Also I've managed to squash another call to ll_rw_block() along the way. There is still one part of the GFS2 I/O paths which are not correctly annotated and that is due to the sharing of the writeback code between the data and metadata address spaces.

* GFS2: Ensure that the inode goal block settings are updatedSteven Whitehouse2009-04-23
| | | | | | | | | | | | | | | | GFS2 has a goal block associated with each inode indicating the search start position for future block allocations (in fact there are two, but thats for backward compatibility with GFS1 as they are set to identical locations in GFS2). In some circumstances, depending on the ordering of updates to the inode it was possible for the goal block settings to not be updated on disk.
