A
system can include a memory device comprising a plurality of
dynamic capacity devices and a
processing device, operatively coupled with the memory device. The
processing device is configured to perform operations including sending, to a memory device, an allocation request to allocate, for a
file system, a first memory section of a plurality of memory sections of a plurality of
dynamic capacity devices associated with the memory device; reserving, for the
file system, a first portion of the first memory section for storing file
metadata of
file system data; reserving, for the file
system, a second portion of the first memory section for storing file data of file
system data; sending, by a first process running on the host system, to the memory device, the file
metadata for storing the file
metadata in the first portion of the first memory section; sending, by a second process running on the host system, to the memory device, a second request to modify the file metadata stored in the first portion of the first memory section; and receiving, from the memory device, a second response indicating an error regarding the second request.
