Hi,
I met the same issue as https://github.com/westerndigitalcorporation/zenfs/issues/199
I set the memory backed to 1 but it still failed to mount because "No valid superblock found".
$ cat /sys/kernel/config/nullb/features memory_backed,discard,bandwidth,cache,badblocks,zoned,zone_size,zone_capacity,zone_nr_conv,zone_max_open,zone_max_active $ cat /sys/kernel/config/nullb/nullb0/memory_backed 1 $ sudo ./plugin/zenfs/util/zenfs mkfs --zbd=nullb0 --aux_path=./plugin/zenfs/logs ZenFS file system created. Free space: 7424 MB $ sudo ./db_bench --fs_uri=zenfs://dev:nullb0 --benchmarks=fillrandom --use_direct_io_for_flush_and_compaction Failed creating env: Invalid argument: NotFound: No valid superblock found: zenfs://dev:nullb0
Linux version: 5.10.0-9-amd64 #1 SMP Debian 5.10.70-1 (2021-09-30) x86_64 GNU/Linux RocksDB version: 7.3
