    SS4000-E problem

    kintech

      I have a problem with ss4000-e storage.

      At one point it refused mount requests and after restart does not start. System web console is not available with "The storage system is currently booting..." , ssh connection is refused also. To recover the data I tried to mount hard disks from ss4000-e to linux box. One of hard disks appeared to be damaged,  but I successfully mount root partition (it was raid of level 1 build from for partitions) and recover system configuration. Now I struggle with data partitions. I assemble and mount the raid5 device with data partition, but it is "Linux plain text" partition which it seems was used by falconstor system as raw device to store the actual xfs partitions.  It seems this is this partition layout from ipstor.conf:
