6 Description: Bring upstream patch for ldiskfs.
10 Description: add support for SLES11 SP1

19 Description: Reduce group prealloc size and skip groups with little free space.
23 Description: Fix issue with proc_remove.
27 Description: add mount option to disable mb_cache since it can cause slowdown.
31 Description: Disable delayed allocation by default for ext4-based ldiskfs on
36 Description: A mount failure can corrupt the slab. This is a bug in the latest
37 RHEL5.5 kernel and only ext4-based ldiskfs is impacted.

57 Frequency : in recovery
59 Description: ext3-corrupted-orphans-2.6.patch added.
60 Details : Backport of ext3 patch to handle corrupted orphans.
62 -------------------------------------------------------------------------------
64 2009-07-31 Sun Microsystems, Inc.
68 Frequency : in recovery
70 Description: don't mix llog inodes with normal.
71 Details : allocate inodes for log in last inode group
73 -------------------------------------------------------------------------------
75 2009-04-20 Sun Microsystems, Inc.
80 Description: minor fixes and cleanups
81 Details : use EXT_UNSET_BLOCK to avoid confusion with EXT_MAX_BLOCK.
82 Initialize 'ix' variable in extents patch to stop compiler warning.
86 Description: update FIEMAP ioctl to match upstream kernel version
87 Details : the FIEMAP block-mapping ioctl had a prototype version in
88 ldiskfs 3.0.7 but this release updates it to match the
89 interface in the upstream kernel, with a new ioctl number.
92 Frequency : only if MMP is active and detects filesystem is in use
94 Description: if MMP startup fails, an oops is triggered
95 Details : if ldiskfs mounting doesn't succeed the error handling doesn't
96 clean up the MMP data correctly, causing an oops.
98 -------------------------------------------------------------------------------
100 2009-04-06 Sun Microsystems, Inc.
106 Description: fix racy locking of mballoc block bitmaps causing BUG
107 Details : The locking of the mballoc buddy bitmap and the in-memory
108 block bitmap was using two different spin locks in some
109 cases. This made it possible to incorrectly access the
110 mballoc bitmap while another process was modifying it,
111 causing a sanity assertion to fail. While no on-disk corruption
112 was reported, there was some risk of this happening.

116 2009-02-07 Sun Microsystems, Inc.
119 Severity : enhancement
121 Description: Get RAID stripe size from superblock
122 Details : RAID striping parameters are now saved in the superblock itself,
123 so we should use these parameters instead of having to specify
124 a mount option each time.
127 Frequency : only if server is running on unsupported big-endian machine
129 Description: Disable big-endian ldiskfs server support.
130 Details : The ldiskfs code is not tested on big-endian machines, and
131 there are known compatibility problems in the extents code
132 when running for most of the kernels. Print an error message
133 and refuse to mount, in case anyone tests this. For existing
134 filesystems that might have been created in this way it is
135 possible to mount with the "bigendian_extents" option to
139 Frequency : only with software RAID-5
141 Description: MMP block reads may fail to detect another user of the filesystem
142 Details : with software RAID it is possible that the RAID driver will
143 cache the MMP block and not refetch it from disk. Force the
144 read to invalidate the RAID page cache and go directly to disk.
146 -------------------------------------------------------------------------------
148 2008-08-31 Sun Microsystems, Inc.
151 Severity : enhancement
153 Description: Interoperability at server side (Disk interoperability)
154 Details : Exported some ldiskfs functions which are required for iop
158 Description: OSS crashes frequently, e2fsck does not fix
159 Details : Add an extra check to ldiskfs extents code for the condition,
160 eh_entries = 0 & eh_depth != 0
164 Description: migrate ldiskfs - ldiskfs2 (extents on directories)
165 Details : disable preallocation for non-regular files.
168 Frequency : blocks per group < blocksize*8 and uninit_groups is enabled
170 Description: ldiskfs error: XXX blocks in bitmap, YYY in gd
171 Details : If blocks per group is less than blocksize*8, set rest of the
175 Frequency : only for filesystems larger than 8TB
177 Description: ldiskfs BUG ldiskfs_mb_use_best_found()
178 Details : The ldiskfs mballoc3 code was using a __u16 to store the group
179 number, but with 8TB+ filesystems there are more than 65536
180 groups, causing an oops.
182 Severity : enhancement
184 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
185 Details : FIEMAP ioctl will allow an application to efficiently fetch the
186 extent information of a file. It can be used to map logical blocks
187 in a file to physical blocks in the block device.
191 Description: mkfs.lustre: Unable to mount /dev/cciss/c0d1:Cannot allocate memory
192 Details : correctly handle device paths using a subdirectory in /dev when
193 creating the per-device procfs directory under /proc/fs/ldiskfs.
195 -------------------------------------------------------------------------------
197 2008-04-26 Sun Microsystems, Inc.
202 Description: Kernel BUG at ... ldiskfs/ldiskfs/mballoc.c:3853
203 Details : Removing the underlying device (e.g. via a SCSI rescan) can cause a
204 kernel BUG in ldiskfs_mb_discard_inode_preallocations().
208 Description: deadlock in ext3_expand_extra_isize
209 Details : Inode expansion during ext3_mark_inode_dirty may lead to deadlock.
210 This is solved by making sure that ext3_expand_extra_isize isn't
211 called from ext3_xattr_set_handle.
215 Description: soft lockups on 1.6.2 MDS (is_subdir)
216 Details : don't add dentries with ".." to dcache and ignore such dentries in
220 Frequency : very rare, if additional xattrs are used on kernels >= 2.6.12
222 Description: files may lose file attributes in some cases
223 Details : If there are multiple extended attributes stored on the inode,
224 in particular ACLs, SELinux, or user attributes (if user_xattr
225 is specified for the client mount options) then there is a risk
226 of attribute loss. If an additional attribute is be stored
227 initially in the inode and then increase in size enough to be
228 moved to the external attribute block (e.g. ACL growing in size)
229 for the attribute to be lost.
233 Description: inode version not being initialized on new inodes
234 Details : The inode i_version field was not being initialized on disk.
235 This field is currently unused but will be needed for VBR.
237 --------------------------------------------------------------------------------
239 2008-01-11 Sun Microsystems, Inc.
244 Description: Add support for vanilla-2.6.22 kernel.
246 --------------------------------------------------------------------------------
248 2007-12-07 Cluster File Systems, Inc. <info@clusterfs.com>
253 Description: statfs speedup patches.
254 Details : The patches improve statfs performance for very large
258 Frequency : if the uninit_groups feature is enabled on ldiskfs
260 Description: e2fsck reports "invalid unused inodes count"
261 Details : If a new ldiskfs filesystem is created with the "uninit_groups"
262 feature and only a single inode is created in a group then the
263 "bg_unused_inodes" count is incorrectly updated. Creating a
264 second inode in that group would update it correctly.
266 --------------------------------------------------------------------------------
268 2007-09-27 Cluster File Systems, Inc. <info@clusterfs.com>
271 Severity : enhancement
273 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
274 Details : FIEMAP ioctl will allow an application to efficiently fetch the
275 extent information of a file. It can be used to map logical blocks
276 in a file to physical blocks in the block device.
278 --------------------------------------------------------------------------------
280 2007-08-29 Cluster File Systems, Inc. <info@clusterfs.com>
286 Description: Multiple mount protection(MMP) support.
287 Details : This feature will protect the filesystem from being mounted more
288 than once simultaneously. It will also protect changes by e2fsprogs
289 to the filesystem if it is mounted. This assumes high importance
290 in a shared storage environment where multiple mounts can severely
291 corrupt the filesystem.
293 --------------------------------------------------------------------------------
295 2007-08-10 Cluster File Systems, Inc. <info@clusterfs.com>
297 * Initial release of ldiskfs as a separate package.
302 Description: Updated patchess for new RHEL4 kernel
303 Details : Add patch ext3-unlink-race.patch
304 Updated series file ldiskfs-2.6-rhel4.series
