From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: The aacraid driver included in all 2.1 ES kernel versions from 2.4.9-e.24 -> 2.4.9-e.49 causes massive data corruption on HP 4M Raid controllers (and, we suspect, other hardware relying on this driver.) We are using Oracle 8i on this kit, and have conducted comprehensive tests on kernels from 2.4.9-e.3 -> 2.4.9-e.49. Patching the kernel with the 1.1.4 aacraid driver from Adaptec fixes this issue, but we note that the problematic 2.1 ES kernels still include a 0.9.9-test6 aacraid version number. This problem does not occur on Redhat 3ES, but again the aacraid driver is at a higher patch version. Version-Release number of selected component (if applicable): kernel-2.4.9-e.24 and above How reproducible: Always Steps to Reproduce: dbverify is an Oracle supplied tool that examines Oracle datafiles for block corruptions. With kernel-2.4.9-e.24 or higher of Redhat ES 2.1, dbverify fails with Oracle datablock corruption issues: DBVERIFY: Release 8.1.7.3.0 - Production on Sat Nov 13 22:47:02 2004 (c) Copyright 2000 Oracle Corporation. All rights reserved. DBVERIFY - Verification starting : FILE = /data/ukhot8i/sms01.dbf Page 3935 is influx - most likely media corrupt *** Corrupt block relative dba: 0x02400f5f (file 0, block 3935) Fractured block found during dbv: Data in bad block - type: 6 format: 2 rdba: 0x02400f5f last change scn: 0x0000.00007c5a seq: 0x1 flg: 0x00 consistency value in tail: 0x07706378 check value in block header: 0x0, block checksum disabled spare1: 0x0, spare2: 0x0, spare3: 0x0 *** The media corruption is sometimes fixed by a filesystem journal rebuild on reboot, but occasionally this does not resolve the problem - leaving the Oracle data corrupt. Additional info:
We will investigate this, and will update the driver in U7 as appropriate.
It looks like this was corrected prior to e.40 From the pensacola changelog: * Fri Jun 18 2004 Jason Baron <jbaron@redhat.com> - update mpt fusion to version 2.05.16, 2.05.11 to backup (Adam Manthei) - update ips to v. 7.00.15, 6.11.07 to backup (Adam Manthei) - update aacraid to 1.1.5-2440, backup 0.9.9 (Adam Manthei) Note the old driver is still shipped, in drivers/addon. The more recent driver can be found in drivers/scsi.
