11 Description: Bring upstream patch for ldiskfs.
15 Description: add support for SLES11 SP1
17 -------------------------------------------------------------------------------
19 2010-07-31 Oracle, Inc.
24 Description: Reduce group prealloc size and skip groups with little free space.
28 Description: Fix issue with proc_remove.
32 Description: add mount option to disable mb_cache since it can cause slowdown.
36 Description: Disable delayed allocation by default for ext4-based ldiskfs on
41 Description: A mount failure can corrupt the slab. This is a bug in the latest
42 RHEL5.5 kernel and only ext4-based ldiskfs is impacted.

62 Frequency : in recovery
64 Description: ext3-corrupted-orphans-2.6.patch added.
65 Details : Backport of ext3 patch to handle corrupted orphans.
67 -------------------------------------------------------------------------------
69 2009-07-31 Sun Microsystems, Inc.
73 Frequency : in recovery
75 Description: don't mix llog inodes with normal.
76 Details : allocate inodes for log in last inode group
78 -------------------------------------------------------------------------------
80 2009-04-20 Sun Microsystems, Inc.
85 Description: minor fixes and cleanups
86 Details : use EXT_UNSET_BLOCK to avoid confusion with EXT_MAX_BLOCK.
87 Initialize 'ix' variable in extents patch to stop compiler warning.
91 Description: update FIEMAP ioctl to match upstream kernel version
92 Details : the FIEMAP block-mapping ioctl had a prototype version in
93 ldiskfs 3.0.7 but this release updates it to match the
94 interface in the upstream kernel, with a new ioctl number.
97 Frequency : only if MMP is active and detects filesystem is in use
99 Description: if MMP startup fails, an oops is triggered
100 Details : if ldiskfs mounting doesn't succeed the error handling doesn't
101 clean up the MMP data correctly, causing an oops.
103 -------------------------------------------------------------------------------
105 2009-04-06 Sun Microsystems, Inc.
111 Description: fix racy locking of mballoc block bitmaps causing BUG
112 Details : The locking of the mballoc buddy bitmap and the in-memory
113 block bitmap was using two different spin locks in some
114 cases. This made it possible to incorrectly access the
115 mballoc bitmap while another process was modifying it,
116 causing a sanity assertion to fail. While no on-disk corruption
117 was reported, there was some risk of this happening.

121 2009-02-07 Sun Microsystems, Inc.
124 Severity : enhancement
126 Description: Get RAID stripe size from superblock
127 Details : RAID striping parameters are now saved in the superblock itself,
128 so we should use these parameters instead of having to specify
129 a mount option each time.
132 Frequency : only if server is running on unsupported big-endian machine
134 Description: Disable big-endian ldiskfs server support.
135 Details : The ldiskfs code is not tested on big-endian machines, and
136 there are known compatibility problems in the extents code
137 when running for most of the kernels. Print an error message
138 and refuse to mount, in case anyone tests this. For existing
139 filesystems that might have been created in this way it is
140 possible to mount with the "bigendian_extents" option to
144 Frequency : only with software RAID-5
146 Description: MMP block reads may fail to detect another user of the filesystem
147 Details : with software RAID it is possible that the RAID driver will
148 cache the MMP block and not refetch it from disk. Force the
149 read to invalidate the RAID page cache and go directly to disk.

153 2008-08-31 Sun Microsystems, Inc.
156 Severity : enhancement
158 Description: Interoperability at server side (Disk interoperability)
159 Details : Exported some ldiskfs functions which are required for iop
163 Description: OSS crashes frequently, e2fsck does not fix
164 Details : Add an extra check to ldiskfs extents code for the condition,
165 eh_entries = 0 & eh_depth != 0
169 Description: migrate ldiskfs - ldiskfs2 (extents on directories)
170 Details : disable preallocation for non-regular files.
173 Frequency : blocks per group < blocksize*8 and uninit_groups is enabled
175 Description: ldiskfs error: XXX blocks in bitmap, YYY in gd
176 Details : If blocks per group is less than blocksize*8, set rest of the
180 Frequency : only for filesystems larger than 8TB
182 Description: ldiskfs BUG ldiskfs_mb_use_best_found()
183 Details : The ldiskfs mballoc3 code was using a __u16 to store the group
184 number, but with 8TB+ filesystems there are more than 65536
185 groups, causing an oops.
187 Severity : enhancement
189 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
190 Details : FIEMAP ioctl will allow an application to efficiently fetch the
191 extent information of a file. It can be used to map logical blocks
192 in a file to physical blocks in the block device.
196 Description: mkfs.lustre: Unable to mount /dev/cciss/c0d1:Cannot allocate memory
197 Details : correctly handle device paths using a subdirectory in /dev when
198 creating the per-device procfs directory under /proc/fs/ldiskfs.

202 2008-04-26 Sun Microsystems, Inc.
207 Description: Kernel BUG at ... ldiskfs/ldiskfs/mballoc.c:3853
208 Details : Removing the underlying device (e.g. via a SCSI rescan) can cause a
209 kernel BUG in ldiskfs_mb_discard_inode_preallocations().
213 Description: deadlock in ext3_expand_extra_isize
214 Details : Inode expansion during ext3_mark_inode_dirty may lead to deadlock.
215 This is solved by making sure that ext3_expand_extra_isize isn't
216 called from ext3_xattr_set_handle.
220 Description: soft lockups on 1.6.2 MDS (is_subdir)
221 Details : don't add dentries with ".." to dcache and ignore such dentries in
225 Frequency : very rare, if additional xattrs are used on kernels >= 2.6.12
227 Description: files may lose file attributes in some cases
228 Details : If there are multiple extended attributes stored on the inode,
229 in particular ACLs, SELinux, or user attributes (if user_xattr
230 is specified for the client mount options) then there is a risk
231 of attribute loss. If an additional attribute is be stored
232 initially in the inode and then increase in size enough to be
233 moved to the external attribute block (e.g. ACL growing in size)
234 for the attribute to be lost.
238 Description: inode version not being initialized on new inodes
239 Details : The inode i_version field was not being initialized on disk.
240 This field is currently unused but will be needed for VBR.
242 --------------------------------------------------------------------------------
244 2008-01-11 Sun Microsystems, Inc.
249 Description: Add support for vanilla-2.6.22 kernel.
251 --------------------------------------------------------------------------------
253 2007-12-07 Cluster File Systems, Inc. <info@clusterfs.com>
258 Description: statfs speedup patches.
259 Details : The patches improve statfs performance for very large
263 Frequency : if the uninit_groups feature is enabled on ldiskfs
265 Description: e2fsck reports "invalid unused inodes count"
266 Details : If a new ldiskfs filesystem is created with the "uninit_groups"
267 feature and only a single inode is created in a group then the
268 "bg_unused_inodes" count is incorrectly updated. Creating a
269 second inode in that group would update it correctly.
271 --------------------------------------------------------------------------------
273 2007-09-27 Cluster File Systems, Inc. <info@clusterfs.com>
276 Severity : enhancement
278 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
279 Details : FIEMAP ioctl will allow an application to efficiently fetch the
280 extent information of a file. It can be used to map logical blocks
281 in a file to physical blocks in the block device.
283 --------------------------------------------------------------------------------
285 2007-08-29 Cluster File Systems, Inc. <info@clusterfs.com>
291 Description: Multiple mount protection(MMP) support.
292 Details : This feature will protect the filesystem from being mounted more
293 than once simultaneously. It will also protect changes by e2fsprogs
294 to the filesystem if it is mounted. This assumes high importance
295 in a shared storage environment where multiple mounts can severely
296 corrupt the filesystem.

302 * Initial release of ldiskfs as a separate package.
307 Description: Updated patchess for new RHEL4 kernel
308 Details : Add patch ext3-unlink-race.patch
309 Updated series file ldiskfs-2.6-rhel4.series
