I'm experiencing problem with fs, reflected by the following errors:

Distribution  - CentOS 5.2
Hardware used - IBM x3650 with ServerRAID10K raid controller and EXP3000 disk
bay (12 SATA disks, RAID0. Total LD size ~8TB).
Tested with different default centos kernels (kernel-2.6.18-92.el5,
kernel-2.6.18-92.1.22.el5), the same
error. Tested also with custom 2.6.28.2 kernel and different FS flags, no
changes.
Hardware used - IBM x3650 with ServerRAID10K raid controller and EXP3000 disk
bay (12 SATA disks, RAID0. Total LD size ~8TB).
Right now running test on 2.6.28.2 with different FS flags, partition sizes and
so on. More that that, dm-crypt module is used
for this partition. But I think it's not dm-crypt related issue.


Right now I'm trying to update mu e2fsprogs utulities and run tests. Still
running and it's seems like FS, created with new e2fsprogs,
 looks more stable.
