Segmentation fault when starting redis server with non existent path to pmfile

[kasiawasiuta]

Having myconfig.conf file with following registration:

pmfile /mnt/non-existent-dir/redis.pm 3gb

and starting redis-server:
./redis-server myconfig.conf
we get:

760:C 07 Feb 18:02:52.638 * Start init Persistent memory file /mnt/non-existent-dir/redis.pm size 3.00G
Segmentation fault (core dumped)

The same situation is when starting two processes of redis-server with two config files pointing to the same pmfile path (which exists in this case)
Redis version: 3.2.7-25-g1e7aa59
Pmdk version: 1.3+b2-614-g1bc6897

I solved to run redis-server with sudo authority.
Or... make directory on user home (ex. /home/totorody/pmem-mnt), and mount /dev/pmem0 to it. then run redis-server without sudo authority.
