I have a block device (
/dev/mapper/vg0-data) on a server. I am planning to mount it locally on the server directly through Linux mount, but also expose is through iSCSI to another server, which will connect to it twice to have multi-path connection. I wonder if this is OK or will there be any data corruption because there might be potentially both local changes on the server and remote changes coming from iSCSI. If there is any caching involved there might be conflicts? Should I mount also locally the block device over iSCSI?
The block device contains an ext4 partition.
This is all on Linux, Ubuntu 16.04 LTS.
