data loss by time travelling of open-e

Hello,

last weekend we restarted our open-e storages after we upgraded the system. One was on u60 and the other one on u55. Some iSCSI target have now only the data until 4.2. which is really strange. Can somebody explain this?

I bootet grml on our secondary open-e systems and can see the lvs. For each lv there is a lv with size 128 MB and the name lv+r+$UUID. The $UUID is the uuid of the original lv. Can somebody tell me what these lvs do? Is there any possibility to recover data?

greetings
Andi
