11 Frequency : in recovery
13 Description: ext3-corrupted-orphans-2.6.patch added.
14 Details : Backport of ext3 patch to handle corrupted orphans.
16 -------------------------------------------------------------------------------
18 2009-07-31 Sun Microsystems, Inc.
22 Frequency : in recovery
24 Description: don't mix llog inodes with normal.
25 Details : allocate inodes for log in last inode group
27 -------------------------------------------------------------------------------
29 2009-04-20 Sun Microsystems, Inc.
34 Description: minor fixes and cleanups
35 Details : use EXT_UNSET_BLOCK to avoid confusion with EXT_MAX_BLOCK.
36 Initialize 'ix' variable in extents patch to stop compiler warning.
40 Description: update FIEMAP ioctl to match upstream kernel version
41 Details : the FIEMAP block-mapping ioctl had a prototype version in
42 ldiskfs 3.0.7 but this release updates it to match the
43 interface in the upstream kernel, with a new ioctl number.
46 Frequency : only if MMP is active and detects filesystem is in use
48 Description: if MMP startup fails, an oops is triggered
49 Details : if ldiskfs mounting doesn't succeed the error handling doesn't
50 clean up the MMP data correctly, causing an oops.
52 -------------------------------------------------------------------------------
54 2009-04-06 Sun Microsystems, Inc.
60 Description: fix racy locking of mballoc block bitmaps causing BUG
61 Details : The locking of the mballoc buddy bitmap and the in-memory
62 block bitmap was using two different spin locks in some
63 cases. This made it possible to incorrectly access the
64 mballoc bitmap while another process was modifying it,
65 causing a sanity assertion to fail. While no on-disk corruption
66 was reported, there was some risk of this happening.
68 -------------------------------------------------------------------------------
70 2009-02-07 Sun Microsystems, Inc.
73 Severity : enhancement
75 Description: Get RAID stripe size from superblock
76 Details : RAID striping parameters are now saved in the superblock itself,
77 so we should use these parameters instead of having to specify
78 a mount option each time.
81 Frequency : only if server is running on unsupported big-endian machine
83 Description: Disable big-endian ldiskfs server support.
84 Details : The ldiskfs code is not tested on big-endian machines, and
85 there are known compatibility problems in the extents code
86 when running for most of the kernels. Print an error message
87 and refuse to mount, in case anyone tests this. For existing
88 filesystems that might have been created in this way it is
89 possible to mount with the "bigendian_extents" option to
93 Frequency : only with software RAID-5
95 Description: MMP block reads may fail to detect another user of the filesystem
96 Details : with software RAID it is possible that the RAID driver will
97 cache the MMP block and not refetch it from disk. Force the
98 read to invalidate the RAID page cache and go directly to disk.

102 2008-08-31 Sun Microsystems, Inc.
105 Severity : enhancement
107 Description: Interoperability at server side (Disk interoperability)
108 Details : Exported some ldiskfs functions which are required for iop
112 Description: OSS crashes frequently, e2fsck does not fix
113 Details : Add an extra check to ldiskfs extents code for the condition,
114 eh_entries = 0 & eh_depth != 0
118 Description: migrate ldiskfs - ldiskfs2 (extents on directories)
119 Details : disable preallocation for non-regular files.
122 Frequency : blocks per group < blocksize*8 and uninit_groups is enabled
124 Description: ldiskfs error: XXX blocks in bitmap, YYY in gd
125 Details : If blocks per group is less than blocksize*8, set rest of the
129 Frequency : only for filesystems larger than 8TB
131 Description: ldiskfs BUG ldiskfs_mb_use_best_found()
132 Details : The ldiskfs mballoc3 code was using a __u16 to store the group
133 number, but with 8TB+ filesystems there are more than 65536
134 groups, causing an oops.
136 Severity : enhancement
138 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
139 Details : FIEMAP ioctl will allow an application to efficiently fetch the
140 extent information of a file. It can be used to map logical blocks
141 in a file to physical blocks in the block device.
145 Description: mkfs.lustre: Unable to mount /dev/cciss/c0d1:Cannot allocate memory
146 Details : correctly handle device paths using a subdirectory in /dev when
147 creating the per-device procfs directory under /proc/fs/ldiskfs.
149 -------------------------------------------------------------------------------
151 2008-04-26 Sun Microsystems, Inc.
156 Description: Kernel BUG at ... ldiskfs/ldiskfs/mballoc.c:3853
157 Details : Removing the underlying device (e.g. via a SCSI rescan) can cause a
158 kernel BUG in ldiskfs_mb_discard_inode_preallocations().
162 Description: deadlock in ext3_expand_extra_isize
163 Details : Inode expansion during ext3_mark_inode_dirty may lead to deadlock.
164 This is solved by making sure that ext3_expand_extra_isize isn't
165 called from ext3_xattr_set_handle.
169 Description: soft lockups on 1.6.2 MDS (is_subdir)
170 Details : don't add dentries with ".." to dcache and ignore such dentries in
174 Frequency : very rare, if additional xattrs are used on kernels >= 2.6.12
176 Description: files may lose file attributes in some cases
177 Details : If there are multiple extended attributes stored on the inode,
178 in particular ACLs, SELinux, or user attributes (if user_xattr
179 is specified for the client mount options) then there is a risk
180 of attribute loss. If an additional attribute is be stored
181 initially in the inode and then increase in size enough to be
182 moved to the external attribute block (e.g. ACL growing in size)
183 for the attribute to be lost.
187 Description: inode version not being initialized on new inodes
188 Details : The inode i_version field was not being initialized on disk.
189 This field is currently unused but will be needed for VBR.
191 --------------------------------------------------------------------------------
193 2008-01-11 Sun Microsystems, Inc.
198 Description: Add support for vanilla-2.6.22 kernel.
200 --------------------------------------------------------------------------------
202 2007-12-07 Cluster File Systems, Inc. <info@clusterfs.com>
207 Description: statfs speedup patches.
208 Details : The patches improve statfs performance for very large
212 Frequency : if the uninit_groups feature is enabled on ldiskfs
214 Description: e2fsck reports "invalid unused inodes count"
215 Details : If a new ldiskfs filesystem is created with the "uninit_groups"
216 feature and only a single inode is created in a group then the
217 "bg_unused_inodes" count is incorrectly updated. Creating a
218 second inode in that group would update it correctly.
220 --------------------------------------------------------------------------------
222 2007-09-27 Cluster File Systems, Inc. <info@clusterfs.com>
225 Severity : enhancement
227 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
228 Details : FIEMAP ioctl will allow an application to efficiently fetch the
229 extent information of a file. It can be used to map logical blocks
230 in a file to physical blocks in the block device.
232 --------------------------------------------------------------------------------
234 2007-08-29 Cluster File Systems, Inc. <info@clusterfs.com>
240 Description: Multiple mount protection(MMP) support.
241 Details : This feature will protect the filesystem from being mounted more
242 than once simultaneously. It will also protect changes by e2fsprogs
243 to the filesystem if it is mounted. This assumes high importance
244 in a shared storage environment where multiple mounts can severely
245 corrupt the filesystem.
247 --------------------------------------------------------------------------------
249 2007-08-10 Cluster File Systems, Inc. <info@clusterfs.com>
251 * Initial release of ldiskfs as a separate package.
256 Description: Updated patchess for new RHEL4 kernel
257 Details : Add patch ext3-unlink-race.patch
258 Updated series file ldiskfs-2.6-rhel4.series
