Hello to all,

I have the following errors in /var/log/messages and I don't know what they mean

And /var/log/dmesg ends with

Code:

md: Autodetecting RAID arrays.
md: autorun ...
md: ... autorun DONE.

EXT3-fs warning: mounting fs with errors, running e2fsck is recommended
EXT3 FS on sdb3, internal journal

EXT3 FS on sda1, internal journal
EXT3-fs: mounted filesystem with ordered data mode.

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

2) w w w .supermicro.com/products/system/1U/5015/SYS-5015M-T.cfm

well, not entirely sure, but raid needs to be checked by the system every once in a while, so try running e2fsck see what happens .

good luck
