ext3-fs error with RAID 5 Array.

[Kannan Raghuprasath <raghuprasath yahoo com>]

Hi,

I have a Fedora core 4 machine (kernel-
2.6.11-1.1369_FC4smp) conneted to external DAS using
Ultra 320 SCSI controller card. The DAS is configured
as RAID 5 of 3.5 TB. I partitioned this array into two
partitions of size 1.9TB and 1.6 TB. These are
assigned to 2 different LUNS so that these two appear
as two partitions in the my Linux machine. 

I use this DAS for backup and after backing up for 30
hours i observe that partition gets remounted as
read-only with following error message in dmesg,

EXT3-fs error (device sdb1): ext3_add_entry: bad entry
in directory #2: directory entry across blocks -
offset=1080, inode=135216, rec_len=4132, name_len=25

Any suggestions on how to solve this problem?

Best regards and thanks in advance for your help,
