I have installed centos 6.2 as virtual host with KVM on servers. Each is connected via SCSI cabling to a HP-MSA500-G2. I've mounted the storage box via multipathd on box machines and both machines can see the data ( ntfs-3g ). But when I add a file via server A, server B can't see it unless I unmount and remount the multipath device - what am I doing wrong? It doesn't matter if I tell the file system to sync etc. - any idea?
NTFS isn't a cluster-aware filesystem - it shouldn't be mounted on two systems at the same time.
Can you clarify what you're trying to achieve with this configuration?
