Multipath mounted read-only

Hi,

I've mounted a partition of our HP P2000 SAN with multipath (/dev/mapper/multipath9p1 mounted as /backup) for our DB backups schedule. I used some of other partitions for Oracle ASM (Automatic Storage Management) on another host using multipath. Then I noticed that my first multipath (9p1) is having I/O problems. so I issued "multipath /dev/sda1" and now its back but it is in read-only state. issuing "multipath -ll" tells me the SAN partition is in r/w mode, but I can't write anything on it.
Any ideas?

fsck on the device? could be that you have some issues with the file system and the kernel mounts it read-only to protect it.

Sorry, umount the device and then run e2fsck or fsck on the devices.
