14 Severity : enhancement
16 Description: Interoperability at server side (Disk interoperability)
17 Details : Exported some ldiskfs functions which are required for iop
21 Description: OSS crashes frequently, e2fsck does not fix
22 Details : Add an extra check to ldiskfs extents code for the condition,
23 eh_entries = 0 & eh_depth != 0
27 Description: migrate ldiskfs - ldiskfs2 (extents on directories)
28 Details : disable preallocation for non-regular files.
31 Frequency : blocks per group < blocksize*8 and uninit_groups is enabled
33 Description: ldiskfs error: XXX blocks in bitmap, YYY in gd
34 Details : If blocks per group is less than blocksize*8, set rest of the
38 Frequency : only for filesystems larger than 8TB
40 Description: ldiskfs BUG ldiskfs_mb_use_best_found()
41 Details : The ldiskfs mballoc3 code was using a __u16 to store the group
42 number, but with 8TB+ filesystems there are more than 65536
43 groups, causing an oops.
45 Severity : enhancement
47 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
48 Details : FIEMAP ioctl will allow an application to efficiently fetch the
49 extent information of a file. It can be used to map logical blocks
50 in a file to physical blocks in the block device.
54 Description: Get RAID stripe size from superblock
55 Details : RAID striping parameters are now saved in the superblock itself,
56 so we should use these parameters instead of having to specify
57 a mount option each time.
61 Description: mkfs.lustre: Unable to mount /dev/cciss/c0d1: Cannot allocate memory
62 Details : correctly handle device paths using a subdirectory in /dev when
63 creating the per-device procfs directory under /proc/fs/ldiskfs.

67 2008-04-26 Sun Microsystems, Inc.
72 Description: Kernel BUG at ... ldiskfs/ldiskfs/mballoc.c:3853
73 Details : Removing the underlying device (e.g. via a SCSI rescan) can cause a
74 kernel BUG in ldiskfs_mb_discard_inode_preallocations().
78 Description: deadlock in ext3_expand_extra_isize
79 Details : Inode expansion during ext3_mark_inode_dirty may lead to deadlock.
80 This is solved by making sure that ext3_expand_extra_isize isn't
81 called from ext3_xattr_set_handle.
85 Description: soft lockups on 1.6.2 MDS (is_subdir)
86 Details : don't add dentries with ".." to dcache and ignore such dentries in
90 Frequency : very rare, if additional xattrs are used on kernels >= 2.6.12
92 Description: files may lose file attributes in some cases
93 Details : If there are multiple extended attributes stored on the inode,
94 in particular ACLs, SELinux, or user attributes (if user_xattr
95 is specified for the client mount options) then there is a risk
96 of attribute loss. If an additional attribute is be stored
97 initially in the inode and then increase in size enough to be
98 moved to the external attribute block (e.g. ACL growing in size)
99 for the attribute to be lost.
103 Description: inode version not being initialized on new inodes
104 Details : The inode i_version field was not being initialized on disk.
105 This field is currently unused but will be needed for VBR.
107 --------------------------------------------------------------------------------
109 2008-01-11 Sun Microsystems, Inc.
114 Description: Add support for vanilla-2.6.22 kernel.
116 --------------------------------------------------------------------------------
118 2007-12-07 Cluster File Systems, Inc. <info@clusterfs.com>
123 Description: statfs speedup patches.
124 Details : The patches improve statfs performance for very large
128 Frequency : if the uninit_groups feature is enabled on ldiskfs
130 Description: e2fsck reports "invalid unused inodes count"
131 Details : If a new ldiskfs filesystem is created with the "uninit_groups"
132 feature and only a single inode is created in a group then the
133 "bg_unused_inodes" count is incorrectly updated. Creating a
134 second inode in that group would update it correctly.

138 2007-09-27 Cluster File Systems, Inc. <info@clusterfs.com>
141 Severity : enhancement
143 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs
144 Details : FIEMAP ioctl will allow an application to efficiently fetch the
145 extent information of a file. It can be used to map logical blocks
146 in a file to physical blocks in the block device.
148 --------------------------------------------------------------------------------
150 2007-08-29 Cluster File Systems, Inc. <info@clusterfs.com>
156 Description: Multiple mount protection(MMP) support.
157 Details : This feature will protect the filesystem from being mounted more
158 than once simultaneously. It will also protect changes by e2fsprogs
159 to the filesystem if it is mounted. This assumes high importance
160 in a shared storage environment where multiple mounts can severely
161 corrupt the filesystem.
163 --------------------------------------------------------------------------------
165 2007-08-10 Cluster File Systems, Inc. <info@clusterfs.com>
167 * Initial release of ldiskfs as a separate package.
172 Description: Updated patchess for new RHEL4 kernel
173 Details : Add patch ext3-unlink-race.patch
174 Updated series file ldiskfs-2.6-rhel4.series
