ext3fs corruption problem?

[Igor Briski]

I've noticed several files missing in last few days and this 
also started happening:

webmail1 [/space/cwmail/mail/n_z1/f6/jejka74_Pmail_Ixxx_Ixx/2] # ls -la
total 32
drwx--S---    2 www-data www-data     4096 Nov 25 22:47 .

-rw-r--r--    1 www-data www-data      613 Nov 25 22:47 m_4.dat

Details:

(/dev/sda4 is a RAID-5 array with 5 disks, 36GB each on a ICP-VORTEX
controller).

And when mounted as ext2, the file stays the same:

webmail1 [/space/cwmail/mail/n_z1/f6/jejka74_Pmail_Ixxx_Ixx/2] # ls -la

drwx--S---    2 www-data www-data     4096 Nov 25 22:47 .

-rw-r--r--    1 www-data www-data      613 Nov 25 22:47 m_4.dat

I've successfully removed the file while mounted as ext2 (haven't tried it
when the partition was mounted as ext3).
