Recommended e2fsprogs version: 1.40.11-sun1
RHEL 4 and RHEL 5/SLES 10 clients behaves differently on cd ./ to a removed current working directory (refer to bugzilla 14399.
A new quota file format was introduced in 1.6.6 (for 2.6.16+ kernels). The format conversion from prior releases is handled transparently, but releases older than 1.6.6/1.8.0 don't understand this new format. The automatic format conversion can be avoided by running the following commands on the MDS and OSS servers (for pre 1.4.12-1.6.5 quota files):
tunefs.lustre --param="mdt.quota_type=ug1" $MDTDEV tunefs.lustre --param="ost.quota_type=ug1" $MDTDEV
or (for 1.4.12/1.6.5 quota files)
tunefs.lustre --param="mdt.quota_type=ug2" $MDTDEV tunefs.lustre --param="ost.quota_type=ug2" $MDTDEV
For more information, please refer to bugzilla 13904.
Output of lfs quota has been made less detailed by default, old (verbose) output can be obtained by using -v option.
File join has been disabled in this release. Refer to bugzilla 16929.
A new Lustre ADIO driver is available for MPICH2-1.0.7.
NFS export disabled when stack size < 8192. Since the NFSv4 export of Lustre file system with 4K stack may cause a stack overflow. For more information, please refer to bugzilla 17630
- Bugzilla: 19601
Severity: enhancement
Description: Update kernel to RHEL5.2 2.6.18-92.1.26.
- Bugzilla: 19453
Severity: critical, only with RHEL4/SLES9 MDS
Description: user xattr corruption
Details: setting extended attributes can corrupt other attributes stored in the inode body. Both user & lustre internal (LOV EA) attributes are concerned. In the latter case, the lustre filesystem can be damaged.
- Bugzilla: 16504
Severity: enhancement
Description: Update kernel to RHEL4.7 2.6.9-78.0.22.
- Bugzilla: 18289
Severity: enhancement
Description: allow the use of the kernel provided OFED stack
Details: This patch allows for lbuild to use the OFED stack provided by the kernel vendor. For the RHEL4 and RHEL5 kernels, we enable the kernel supplied OFED stack.
- Bugzilla: 18775
Severity: enhancement
Description: improve lctl set/get_param
Details: handle the bad options, support more than one arguments, add '-F' option to append the indicator to the parameters.
- Bugzilla: 19212
Severity: enhancement
Description: Update kernel to SLES10 SP2 2.6.16.60-0.37.
- Bugzilla: 19495
Severity: major
Frequency: rare
Description: fix lqs' reference which won't be put in some situations.
Details: This patch fixes:
- In quota_check_common(), this function will check quota for user and group, but only send one return via "pending". In most cases, the pendings should be same. But that is not always the case.
- If quotaoff runs between lquota_chkquota() and lquota_pending_commit(), the same thing will happen too. That is why it comes:
if (!ll_sb_any_quota_active(qctxt->lqc_sb)) RETURN(0);

- Bugzilla: 18810
Severity: major
Frequency : rare
Description: fix racy locking of mballoc block bitmaps causing BUG
Details: The locking of the mballoc buddy bitmap and the in-memory block bitmap was using two different spin locks in some cases. This made it possible to incorrectly access the mballoc bitmap while another process was modifying it, causing a sanity assertion to fail. While no on-disk corruption was reported, there was some risk of this happening.
- Bugzilla: 18480
Frequency: common
Description: correct count of recoverable clients
Details: if recovery failed for client for some reasons (goal inode or something else) server can wait failed clients for finish recovery.
- Bugzilla: 18695
Severity: critical
Frequency: when directories had atime set in past (e.g. untar)
Descriptoin: Lustre detected file system corruption with inode out of bounds
Details: don't update i_size on MDS_CLOSE for directories. This causes directory corruptions on the MDT.
- Bugzilla: 18895
Severity: normal
Frequency: on failed service startup
Description: replay-single test_61d: LustreError: 17392:0:(lprocfs_status.c:859:lprocfs_obd_cleanup()) ASSERTION(obd->obd_proc_exports_entry->subdir == NULL) failed
Details: cleanup lprocfs entries on error.
- Bugzilla: 18903
Severity: normal
Frequency: rare
Description: llmount.sh: BUG: spinlock wrong owner on CPU#0, mount.lustre/8180
Details: fix typo in import_set_conn() causing spinlock corruption.
- Bugzilla: 18859
Severity: normal
Frequency: rare, only when using group lock on client
Description: Group Lock in Lustre: write call is blocking
Details: fix wrong return code of ll_is_file_contended() causing processes to be blocked indefinitely.
- Bugzilla: 17757
Severity: normal
Frequency: rare
Description: ASSERTION(new_lock != NULL) failed:op 0x1 lockh 0x0
Details: DISP_OPEN_LOCK is not cleared properly in reconstruct_open() since intent_disposition() is used instead of intent_set_disposition().
- Bugzilla: 15428
Severity: major
Frequency: occasional when using software RAID5
Description: raid5 panics
Details: fix panic in raid5_end_read_request().

- Bugzilla: 16498
Severity: normal
Description: Get RAID stripe size from superblock
Details: RAID striping parameters are now saved in the superblock itself, so we should use these parameters instead of having to specify a mount option each time.
- Bugzilla: 16438
Severity: major
Description: Disable big-endian ldiskfs server support.
Details: The ldiskfs code is not tested on big-endian machines, and there are known compatibility problems in the extents code when running for most of the kernels. Print an error message and refuse to mount, in case anyone tests this. For existing file systems that might have been created in this way it is possible to mount with the "bigendian_extents" option to force the mount.
- Bugzilla: 15983
Severity: major
Description: workaround for OOM from o2iblnd
Details: OFED needs allocate big chunk of memory for QP while creating connection for o2iblnd, OOM can happen if no such a contiguous memory chunk. QP size is decided by concurrent_sends and max_fragments of o2iblnd, now we permit user to specify smaller value for concurrent_sends of o2iblnd(i.e: concurrent_sends=7), which will decrease memory block size required by creating QP.

- Bugzilla: 16081
Severity: normal
Frequency: rare
Description: don't skip ost target if they assigned to file
Details: Drop slow OSCs if we can, but not for requested start idx. This means "if OSC is slow and it is not the requested start OST, then it can be skipped, otherwise skip it only if it is inactive/recovering/out-of-space.

Severity: normal
Description: ll_read_ahead_pages()) ASSERTION(page_idx > ria->ria_stoff) failed
Details: Once the unmatched stride IO mode is detected, shrink the stride-ahead window to 0. If it does hit cache miss, and read pattern is still stride-io mode, does not reset the stride window, but also does not increase the stride window length in this case.
- Bugzilla: 16438
Severity: normal
Frequency: only for big-endian servers
Description: Check if system is big-endian while mounting fs with extents
Details: Mounting a file system with extents feature will fail on big-endian systems since ext3-based ldiskfs is not supported on big-endian systems. Can be bypassed with "bigendian_extents" mount option.
- Bugzilla: 16860
Severity: normal
Description: Excessive recovery window
Details: With AT enabled, the recovery window can be excessively long (6000+ seconds). To address this problem, we no longer use OBD_RECOVERY_FACTOR when extending the recovery window (the connect timeout no longer depends on the service time, it is set to INITIAL_CONNECT_TIMEOUT now) and clients report the old service time via pb_service_time.
- Bugzilla: 16522
Severity: normal
Description: Watchdog triggered on MDS failover
Details: enable OBD_CONNECT_MDT flag when connecting from the MDS so that the OSTs know that the MDS "UUID" can be reused for the same export from a different NID, so we do not need to wait for the export to be evicted.
- Bugzilla: 16839
Severity: normal
Frequency: start MDS on uncleanly shutdowned MDS device
Description: ll_sync thread stay in waiting mds<>ost recovery finished
Details: fix race due to two ll_sync threads processing the same lov target causing random failures in various tests. The solution is to send ACTIVATE event only if connect already finished and import is in FULL state.
- Bugzilla: 17895
Severity: major
Frequency: rare, only if using MMP with Linux RAID
Description: MMP doesn't work with Linux RAID
Details: While using HA for Lustre servers with Linux RAID, it is possible that MMP will not detect multiple mounts. To make this work we need to unplug the device queue in RAID when the MMP block is being written. Also while reading the MMP block, we should read it from disk and not the cached one.

- Severity: critical
Frequency: very rare, if additional xattrs are used on kernels >= 2.6.12
Bugzilla: 15777
Description: MDS may lose file striping (and hence file data) in some cases
Details: If there are additional extended attributes stored on the MDS, in particular ACLs, SELinux, or user attributes (if user_xattr is specified for the client mount options) then there is a risk of attribute loss. Additionally, the Lustre file striping needs to be larger than default (e.g. striped over all OSTs), and an additional attribute must be stored initially in the inode and then increase in size enough to be moved to the external attribute block (e.g. ACL growing in size) for file data to be lost.

Description: Grant leak when OSC reconnect to OST
Details: When osc reconnect ost, OST(filter) should check whether it should grant more space to client by comparing fed_grant and cl_avail_grant, and return the granted space to client instead of "new granted" space, because client will call osc_init_grant to update the client grant space info.

Details: When then OST is about to be full, if two bulk writing from different clients came to OST. Accord the avaliable space of the OST, the first req should be permitted, and the second one should be denied by ENOSPC. But if the seconde arrived before the first one is commited. The OST might wrongly permit second writing, which will cause grant space > avaiable space.

Details: when the import is evicted by server, it will fork another thread ptlrpc_invalidate_import_thread to invalidate the import, where the grant will be set to 0. While the original thread will update the grant it got when connecting. So if the former happened latter, the grant will be wrongly errased because of this race.

Bugzilla: 12316
Description: Add OFED1.2 support to o2iblnd
Details: o2iblnd depends on OFED's modules, if out-tree OFED's modules are installed (other than kernel's in-tree infiniband), there could be some problem while insmod o2iblnd (mismatch CRC of ib_* symbols). If extra Module.symvers is supported in kernel (i.e, 2.6.17), this link provides solution: https://bugs.openfabrics.org/show_bug.cgi?id=355 if extra Module.symvers is not supported in kernel, we will have to run the script in bug 12316 to update $LINUX/module.symvers before building o2iblnd. More details about this are in bug 12316.

Bugzilla: 11616
Description: o2iblnd handle early RDMA_CM_EVENT_DISCONNECTED.
Details: If the fabric is lossy, an RDMA_CM_EVENT_DISCONNECTED callback can occur before a connection has actually been established. This caused an assertion failure previously.
- Severity: major
Bugzilla: 11201
Description: lnet deadlock in router_checker
Details: turned ksnd_connd_lock, ksnd_reaper_lock, and ksock_net_t:ksnd_lock into BH locks to eliminate potential deadlock caused by ksocknal_data_ready() preempting code holding these locks.
- Severity: major
Bugzilla: 11126
Description: Millions of failed socklnd connection attempts cause a very slow FS
Details: added a new route flag ksnr_scheduled to distinguish from ksnr_connecting, so that a peer connection request is only turned down for race concerns when an active connection to the same peer is under progress (instead of just being scheduled).
