Problems with RAID1 array
Hi,
First let me thank you for your work on this. It's really nice software and quite helpful for a dual boot system.
I am running a dual boot system with Win10 21H1 and Linux Fedora34.
I decided to create a btrfs RAID1 volume on my Fed34 with two 14TB HDs, using BLAK2b as checksum algo and noatime for mounting. This is to store all my important files: my films, photos, music, etc. I use Win10 to watch the films, because Linux has not the same quality and speed, and for that I am using Winbtrfs to mount this volume on Windows, and, for safety, I set the volume only as readonly in Win10. Unfortunately, this configuration is not usable at all. Whenever I try to watch a film directly from this volume I hear a lot of noise coming from my computer (the intensive read access sound from the hard disks), the file explorer blocks completely, and I always have to shutdown my computer. I have another btrfs RAID0 volume on my Fed34 with two 1TB SSDs, using xxhash, and this works flawlessly on Win10. This I run with both R/W access. I already thought of running the RAID1 with R/W, but considering the behaviour I'm gettting I'm afraid of having the volume corrupted, so, I would rather not try that. I tried to see if I could mount the volume on Windows 10 with the noatime option, but I cannot find any setting for that, so, I'm assuming it's on, and maybe this could be the issue? I'm not sure if this is a bug or normal performance with hard disks, but considering that the disks get fully blocked, I suspect something is not right...
Please let me know if I could give you more info on how to debug this. I'm using version 1.7.8.1
Thanks!
An update after testing version 1.7.9...
It still has the problem, but is not as bad as 1.7.8.1: -on folders with a small number of files the system is usable, but if the number of files is significant (50+), it starts behaving the same way. However, it improved slightly, because if I close File Explorer, the system hangs for a few minutes, but eventually it closes File Explorer and stops the intense reading of the disks, and the system becomes responsive again without having to restart it. -I've tried mounting the volume as Read/Write, but same behaviour, so, not related to have it as Readonly. -I've noticed that on the RAID0 volume, the one that works fine, if I see the volume properties the "Allow files on this drive to have contents indexed..." is not enabled, however, on the RAID1 volume, it is enabled. I wonder if this could be one of the possible causes? -I have also tried to disable the automatic folder type detection, but I'm not sure if your driver is ignoring that. Maybe could also be one of the potential issues? -Is there any option to decide how to mount the volumes either with noatime or relatime?
Please let me know if I could help you debugging this in any way.
Thank you.
