Yes, I thought those symptoms sounded familiar, and consistent with a 
read-only filesystem.  I've seen that happen when a disk is in the 
process of dying, but it has happened occasionally for no apparent 
reason.  My *guess* (and not a well-documented one, at that) for when I 
am unable to pinpoint a disk error is that the filesystem got too busy 
for the controller (or slow disk) to keep up with.  Or a controller 
error.    If it's a hardware RAID (and a true hardware RAID) then either 
there is failure across multiple disks, or the controller has thrown an 
error.

At any rate, it's tough to pin down exactly, since by the time the error 
is encountered, the kernel has already dropped the filesystem to 
read-only, so there is no log entry.   If you catch it quickly enough 
and haven't rebooted, maybe dmesg can help.

Best of luck to Janwillem on this issue.
