Hello guys! made an account just because of this thread. I’m a developer for the DANOS project at AT&T. I’ve worked with squashfs and imaging snapshots for the past few years amongst other dataplane related projects. I recently acquired myself a new PC for doing some storage projects on. Here’s the jist (I‘ll post more specifics later, on my phone right now): Desktop: ryzen 3960x 3 x 1TB Sabernet nvme 4 asrock trx40 creator Portable: lenovo x1 carbon 5th gen 512mb intel pro nvme anyways the goal is to create a end-all-be-all file system for me to use (for the rest of my life). The solutions I’ve been experimenting with is: Desktop: HW: - 3 x 1 TB nvme 4 - uefi chipset SW: - md raid 5 for a total of 2tb workable - Luks encryption - btrfs with multiple subvolumes for home/kernel files My hope is to use nvme over fabrics to mount first my desktop home partition as my home directory on my portable. However I’ve been encountering sync issues. My question to you all, do you know how file flushes behave with nvmeof? For example if I have a network mounted nvmeof+ext4 file system and a write a file to this portion, will other simultaneously mounted file system clients on the fabrics get a write update? As far as I can tell writes to the actual hardware don’t happen till the client unmounts. Other clients also need to re-mount in order to see the file changes. Has anyone encountered something like this or could I be using a dated set up? will be posting more exact config/details later on today but thought I’d get this rolling. thanks erik
