/usr/include/asm/errno.h says -30 = -EROFS. That means your OST filesystem
has likely been remounted read-only because of a detected filesystem error.
Check your /var/log/messages for something like "LDISKFS-fs error ...:
Remounting filesystem read-only". This will be accompanied by the reason
the filesystem is read-only.
Cheers, Andreas
