[Gluster-users] GlusterFS Changing Hash of Large Files?
I've got a new glusterfs 4 node replica cluster running under CentOS 7. All hosts are backed by SSD drives and are connected to a 1Gbps Ethernet network. 3 nodes are running on CentOS 7 under ESXi on the same physical host, 1 is running on CentOS 7 under Hyper-V. I use this for my docker swarm persistent storage and all seems to work well. Yesterday however, I copied a 4GB .ISO file to my volume for a friend to download. I noticed the SHA256 hash of the ISO was altered. I downloaded a fresh copy to my desktop, verified the hash, scp'd it to the local glusterfs host storage and again, re-verified the hash. The moment I copied it to my glusterfs volume, the file hash changed. When my friend downloaded the ISO, his hash matched changed hash. I am new to glusterfs, having deployed this as my first cluster ever about a week ago. Can someone help me work through why this file's hash would be changing? -------------- next part -------------- An HTML attachment was scrubbed...
