Sorry for my weak descriptions.
here is a hopefully better list:

Tyan Tomcat i7230W
3,20GHz Pentium 541 S775
RAID bus controller: Adaptec Serial ATA II RAID 1420SA (weak driver support
known)
4x Samsung 320GB S-ATA2

disk 2+3 as raid 1
both raid devices in one volume group
LV 1 Size 19.53 GB (never had problems)
LV 2 Size 576.64 GB (problems during fsck)
No dmesg problems, no syslog problems
Server 2: (Dapper)
Tyan Tomcat i7230W
3,20GHz Pentium 541 S775
RAID bus controller: Adaptec Serial ATA II RAID 1420SA (weak driver support
known)

Server 3: (Dapper)
Tyan Tomcat i7230W
3,20GHz Pentium 541 S775
RAID bus controller: Adaptec Serial ATA II RAID 1420SA (weak driver support
known)
4x Samsung 320GB S-ATA2
all disks in one volume group
LV 1 Size 1.16 TB (problems during fsck)
No dmesg problems, no syslog problems
At these three machines I also chanced the prots at the S-ATA Controller
and the cables to be sure, that not one channel or cable is the bad one.
Nothing has chanced.
Right now the e2fsck.static you send is running and it finds continues errors
that it tries to correct.
If it gets finished with the message (message of Server 2 lv 5)
***** FILE SYSTEM WAS MODIFIED *****
54323/16744448 files (5.7% non-contiguous), 24520632/33464320 blocks
you can restart e2fsck.static as often as you want and he will still find
errors that it corrects.
Right now its running the 9th time and still finds errors.

Server 8 (Dapper)
was a dedicated Server, but doesn't exist anymore.
was an Athlon ~ 3Ghz
had 2 S-ATA Disks
no raid
one part of disk 1 was for OS, rest LVM, Disk 2 was complete LVM, both together
in one VG
had errors on one LV other LV's made no problems.
Sorry, but I can't find any documentation of this box anymore and it isn't sold
anymore.
I only listed Server where errors appeared and the Servers with the same
hardware where no errors appeared. Several other Servers with or without
Software Raid, nearly all with LVM have no problems at all. In total I'm
responsible for 27 Servers an a few Desktop / Notebook's. All running
under Ubuntu from Dapper to Hardy.
I hope this Informations are more helpful than my posts before.
Sorry for making more trouble then necessary.
If you still need more Informations, I'll try to give them.
