Stephen Tweedie backported these two patches into RHEL 3. A RHEL 3 .31EL
beehive based test kernel with these two patches had been sent to customer
site.
*** Bug 161056 has been marked as a duplicate of this bug. *** Created attachment 116401 [details] aclbreak.tar.gz Test case from bug #161056. A fix for this problem has just been committed to the RHEL3 U6 patch pool this evening (in kernel version 2.4.21-32.12.EL). An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.3) Gecko/20040924 Description of problem: Based on the fsck log we collected from a customer site that reported data corruptions with a 1.8TB filesystem on RHEL 3 system, it was tentatively concluded that the issues found in bugzilla 138951 (opened against RHEL 4) was the cause. The filesystem is mounted as smb share that gets accessed via Window machines. The symptoms include "ls" error messages such as: [root@nycpr350fil graphics]# ls -al ls: athletic.zip: Input/output error ls: â¢DSC_0010.psd: Input/output error ls: â¢DSC_0014.psd: Input/output error ls: WeatherPlusLOGOfeb9.eps: Input/output erro From /var/log/messages file: EXT3-fs error (device power2(232,49)): ext3_free_blocks: bit already cleared for block 33103513 that shows bitmap corruption. The blocks that are in use may be marked as available for reuse and subsequently get allocated as "free" blocks. Version-Release number of selected component (if applicable): kernel-2.4.21-31.ELsmp How reproducible: Didn't try Steps to Reproduce: 1. (occurs twice on mission cirtical production system) 2. 3. Actual Results: filesystem corrupted Expected Results: no corrutions Additional info: This has been occurred twice on a mission critical system with large LUN (1.8TB). Other than downtime is not acceptable, the fsck time for the LUN with this size is also unmanageable.
