flashcache_create:Error #71

well, after installing, I just commanded "sudo flashcache_create -p back -s 1g -b 4k cachedev /dev/sda1 /dev/sdb1/"

but it didn't work...(Segmentation fault)

I have no idea how I fixed this problem...

here, what's happening after command :

cachedev cachedev, ssd_devname /dev/sda1, disk_devname /dev/sdb1 cache mode WRITE_BACK
block_size 8, md_block_size 0, cache_size 8
Flashcache metadata will use 4MB of your 0MB main memory
Proportion of main memory needed for flashcache metadata is high.
You can reduce this with a smaller cache or a larger blocksize.
Are you sure you want to proceed ? (y/n): y

Segmentation fault

@Sjafari

Same thing happened with me. Can anyone please help ?
I was testing flashcache on my machine with a 100 mb cache device and 1 gb disk (loop devices)

cachedev Flash, ssd_devname /dev/loop1, disk_devname /dev/loop2 cache mode WRITE_BACK
block_size 8, md_block_size 0, cache_size 8
Flashcache metadata will use 1075970048MB of your 2036MB main memory
Proportion of main memory needed for flashcache metadata is high.
You can reduce this with a smaller cache or a larger blocksize.
