The server has 2 hdd raid (hardware) sata (250GB each) and CentOS 5.1 Final (2.6.18-53)

When the clients try to copy some files on the server (Samba file share) (~6GB total) when is almost over they receive an error that the disk may be full or write protected and I found that the partition was suddenly mounted read only. This is the first server I partitioned wrong, I mean I didn't use a separate partition for /home where my samba share is so the entire / partition was read only.

the partitions were
1) /
2) /boot
3) swap

I usualy use
1) /
2) /home
3) /boot
4) swap

Thank you

P.S. I don't know exactly (I didn't bought it) but one of this is the server
