[Ocfs2-users] ocfs2 remounted read only

[Antonello Cioffi]

Hello

yesterday my ocfs2 fail after about 5 months of usage.

First I had high load on one of the two node. I rebooted it and at 
reboot these messeges appered:

Feb 10 20:33:22 posta-n kernel: [   90.342829] o2net: accepted 
connection from node posta2 (num 1) at 172.16.1.2:7777

Feb 10 19:44:01 posta-n kernel: [  727.825761] File system is now 
read-only due to the potential of on-disk corruption. Please run 
fsck.ocfs2 once the file system is unmounted.

OCFS2_VALID_FL not set
Feb 10 19:44:01 posta-n kernel: [  727.826728]

now I migrate all files to a new ocfs2 partition and I'm using this new 
one to come back online.

I'm using two SLES 11sp3 with this packages

ocfs2-tools-o2cb-1.8.2-0.15.5
ocfs2-kmp-default-1.6_3.0.76_0.9-0.16.24
ocfs2-kmp-trace-1.6_3.0.76_0.9-0.16.24
ocfs2-tools-1.8.2-0.15.5
ocfs2console-1.8.2-0.15.5
ocfs2-tools-devel-1.8.2-0.15.5

How can I figure what appened and is there anything I can do to avoid 
the occuring again?

According to software storage all disks are ok.

thank you

greetings
