Configuration

1./*prepare disk, from 0 to num_of_your_disks for each node*/mkdir -p /opt/sdfs/data/cds/0mkfs.ext4 /dev/sdxblkid /dev/sdxecho 'UUID="you-disk-uuid" /opt/sdfs/data/cds/0 ext4 user_xattr,noatime,defaults 0 0' >> /etc/fstabmount /dev/sdx /opt/sdfs/data/cds/0/*prepare a ssd or nvme for redis mount*/mkdir -p /opt/sdfs/data/redis/0mkfs.ext4 /dev/sdyblkid /dev/sdyecho 'UUID="you-disk-uuid" /opt/sdfs/data/redis/0 ext4 user_xattr,noatime,defaults 0 0' >> /etc/fstabmount /dev/sdy /opt/sdfs/data/redis/02.modify config, only modify one of your nodes:vim /opt/sdfs/etc/cluster.confupdate hosts in first column, cds with num_of_disks for example:auto1.host155.vmnode31  redis[0,1] mond[0] cds[0,1,2,3,4,5,6] nfs[0]auto1.host155.vmnode32  redis[0,1] mond[0] cds[0,1,2,3,4,5,6] nfs[0]auto1.host155.vmnode33  redis[0,1] mond[0] cds[0,1,2,3,4,5,6] nfs[0]vim /opt/sdfs/etc/sdfs.conf update gloconf.networks, if only single host,then add config:solomode on; for example:networks {    192.168.140.0/8;}vim /etc/hostsupdate hosts, for example:192.168.140.31 auto1.host155.vmnode31192.168.140.32 auto1.host155.vmnode32192.168.140.33 auto1.host155.vmnode33
