Help: Hard Disk & MySQL Server Suddenly Read-Only

Suddenly my Hard-disk & MySQL Server had gone read-only, thereby making this blog (because it is cached) and other sites inaccessible, including ssh access. Do you have any idea why this could have happened?

A hard reboot rectified the error for now. But I am concerned about what caused this in the first place. Any ideas?

Any help would be highly appreciated.

I’ve had this problem a few times now, but only on hosts running inside VMWare. Eg we have some mysql servers as virtual servers inside the VMWare environment and every now and then it gets set to read-only.
I have no idea of any resolution yet.

Maybe it’s outdated but I just bumped into this post. This happend to me twice in the last 6 months. Both time it was caused by the multiple hard disk/file system errors. “mount -o remount,rw /data” nor “hdparm -r 0 /dev/hdaX” helped as it does not clear the errors, only reboot did. I am not sure if the error was caused by hardware or software error but I changed the discs anyway, the data was to sensitive to risk loosing it.
