We have a crash in the raid controller. After replacing it and assembling a new raid from old disks (without reinitializing them), we were able to access the file system.
But to our disappointment, the volumes of lvm were not available to us. It seems that the metadata of thin volumes was violated.
What actions can be taken in this situation, and is it realistic to save the data?
