Thank you very much , actually , i am looking for a way to reduce disk dynamiclly , i hope to reducing one node disk a time , our replication factor is 1 , we can accept one node data unaccessible at a period of time .
i think if i can reduce the disk size once at a time , I ask this question because I find the aerospike process will preallocated the disk when it start ,
ls -al will find the file size will be the value i had set in the configure file ,even if i don’t write any data to AS. so , i fear to lossing data if i change the file size after the data file has been allocated .
i also want to know why the documentation says ,resize the disk need a cold restart .what risk or error would happen if i use rolling restart .
Look forward to your reply : )
