However, mount can't find a filesystem. Bit more info - I checked the partition sizes (I was playing around with some) - but they cylinder numbers are the same as the list I have before I started. Second - its a 3gb partition, and the missing logical volume is a 10Gb one. Hence, the last 7Gb are on the OK physical volumes. Can I get back at least those, if not the whole lot. Alternatively, at this point the question might better be asked to the reiserfs lists.
