During the boot sequence of a Xenta Server the message "Unmap block xxx at remount" occurs.
TAC I/NET, TAC Vista, Satchwell MicroNet
Sections of the flash drive are being declared bad and are being removed from the accessible drive map. This can be a natural pruning process of bad sections due to drive damage or that section exceeding the maximum number of writes.
The amount of lost space is:
# of pages * 2 bytes
All hardware 2 Xenta Servers have 16mb flash drives, so it takes a large number of pages to be lost before significant space is lost and will impact performance of the unit.
If the number of pages is low and is not increasing then the unit should function normally without any additional action.
If the number of pages is exceeding 50000 or increasing rapidly, then have the Xenta Server repaired or replaced depending on its age.
