Subject: Superblock checksum problems
Date: Sat, 02 Sep 2006 18:36:50 -0400 [thread overview]
Message-ID: <1157236610.8070.7.camel@localhost> (raw)
Attempting to build a new raid5 md array across 4 hard drives. At the
exact moment that the drive finishes rebuilding, the superblock checksum
changes to an invalid value. During the rebuild, mdadm -E for the 4
drives shows:
Checksum : 70c0863a - correct
Checksum : 70c0864c - correct
Checksum : 70c0865e - correct
Checksum : 70c08670 - correct
The instant it finishes:
Checksum : 70c0bc47 - expected 70c0bc27
Checksum : 70c0bc59 - expected 70c0bc39
Checksum : 70c0bc6b - expected 70c0bc4b
Checksum : 70c0bc7d - expected 70c0bc5d
Kernel is 2.6.17.11.
Controller is 4-port silicon image:
0000:00:08.0 RAID bus controller: Silicon Image, Inc. SiI 3114
[SATALink/SATARaid] Serial ATA Controller (rev 02)
Drives are seagate 250G sata ST3250824AS
